The New Advanced Telescope for High ENergy Astrophysics (NewAthena) will be the largest space-based X-ray observatory ever built. It will have an effective area above 1.1 m2 at 1 keV, which corresponds to a polished mirror surface of about 300 m2 due to the grazing incidence. As such a mirror area is not achievable with an acceptable mass even with nested shells, silicon pore optics (SPO) technology will be utilized. In the PTB laboratory at BESSY II, two dedicated beamlines are in use for their characterization with monochromatic radiation at 1 keV and a low divergence well below 2 arcsec: the X-ray Pencil Beam Facility (XPBF 1) and the X-ray Parallel Beam Facility (XPBF 2.0), where beam sizes up to 8 mm × 8 mm are available while maintaining low beam divergence. This beamline is used for characterizing mirror stacks and controlling the focusing properties of mirror modules (MMs) – consisting of four mirror stacks – during their assembly at the beamline. A movable CCD based camera system 12 m from the MM registers the direct and the reflected beams. The positioning of the detector is verified by a laser tracker. The energy-dependent reflectance in double reflection through the pores of an MM with an Ir coating was measured at the PTB four-crystal monochromator beamline in the photon energy range 1.75 keV to 10 keV, revealing the effects of the Ir M edges. The measured reflectance properties are in agreement with the design values to achieve the envisaged effective area.

The advent of diffraction-limited storage rings (DLSRs) has boosted the brilliance or coherent flux by one to two orders of magnitude with respect to the previous generation. One consequence of this brilliance enhancement is an increase in the flux density or number of photons per unit of area and time, which opens new possibilities for the spatiotemporal resolution of X-ray imaging techniques. This paper studies the time-resolved microscopy capabilities of such facilities by benchmarking the ForMAX beamline at the MAX IV storage ring. It is demonstrated that this enhanced flux density using a single harmonic of the source allows micrometre-resolution time-resolved imaging at 2000 tomograms per second and 1.1 MHz 2D acquisition rates using the full dynamic range of the detector system.

Advances in physics have been significantly driven by state-of-the-art technology, and in photonics and X-ray science this calls for the ability to manipulate the characteristics of optical beams. Orbital angular momentum (OAM) beams hold substantial promise in various domains such as ultra-high-capacity optical communication, rotating body detection, optical tweezers, laser processing, super-resolution imaging etc. Hence, the advancement of OAM beam-generation technology and the enhancement of its technical proficiency and characterization capabilities are of paramount importance. These endeavours will not only facilitate the use of OAM beams in the aforementioned sectors but also extend the scope of applications in diverse fields related to OAM beams. At the FERMI Free-Electron Laser (Trieste, Italy), OAM beams are generated either by tailoring the emission process on the undulator side or, in most cases, by coupling a spiral zone plate (SZP) in tandem with the refocusing Kirkpatrick–Baez active optic system (KAOS). To provide a robust and reproducible workflow to users, a Hartmann wavefront sensor (WFS) is used for both optics tuning and beam characterization. KAOS is capable of delivering both tightly focused and broad spots, with independent control over vertical and horizontal magnification. This study explores a novel non-conventional `near collimation' operational mode aimed at generating beams with OAM that employs the use of a lithographically manufactured SZP to achieve this goal. The article evaluates the mirror's performance through Hartmann wavefront sensing, offers a discussion of data analysis methodologies, and provides a quantitative analysis of these results with ptychographic reconstructions.

An innovative dual-thickness semi-transparent beamstop designed to enhance the performance of small-angle X-ray scattering (SAXS) experiments is introduced. This design integrates two absorbers of differing thicknesses side by side into a single attenuator, known as a beamstop. Instead of completely stopping the direct beam, it attenuates it, allowing the SAXS detector to measure the transmitted beam through the sample. This approach achieves true synchronization in measuring both scattered and transmitted signals and effectively eliminates higher-order harmonic contributions when determining the transmission light intensity through the sample. This facilitates and optimizes signal detection and background subtraction. This contribution details the theoretical basis and practical implementation of this solution at the SAXS station on the 1W2A beamline at the Beijing Synchrotron Radiation Facility. It also anticipates its application at other SAXS stations, including that at the forthcoming High Energy Photon Source, providing an effective solution for high-precision SAXS experiments.

The crystal structure of a new 1:1 cocrystal of carbamazepine and S-naproxen (C15H12N2O·C14H14O3) was solved from powder X-ray diffraction (PXRD). The PXRD pattern was measured at the high-resolution beamline CRISTAL at synchrotron SOLEIL (France). The structure was solved using Monte Carlo simulated annealing, then refined with Rietveld refinement. The positions of the H atoms were obtained from density functional theory (DFT) ground-state calculations. The symmetry is ortho­rhom­bic with the space group P212121 (No. 19) and the following lattice parameters: a = 33.5486 (9), b = 26.4223 (6), c = 5.3651 (10) Å and V = 4755.83 (19) Å3.

Single-particle cryo-electron microscopy has become a widely adopted method in structural biology due to many recent technological advances in microscopes, detectors and image processing. Before being able to inspect a biological sample in an electron microscope, it needs to be deposited in a thin layer on a grid and rapidly frozen. The VitroJet was designed with this aim, as well as avoiding the delicate manual handling and transfer steps that occur during the conventional grid-preparation process. Since its creation, numerous technical developments have resulted in a device that is now widely utilized in multiple laboratories worldwide. It features plasma treatment, low-volume sample deposition through pin printing, optical ice-thickness measurement and cryofixation of pre-clipped Autogrids through jet vitrification. This paper presents recent technical improvements to the VitroJet and the benefits that it brings to the cryo-EM workflow. A wide variety of applications are shown: membrane proteins, nucleosomes, fatty-acid synthase, Tobacco mosaic virus, lipid nanoparticles, tick-borne encephalitis viruses and bacteriophages. These case studies illustrate the advancement of the VitroJet into an instrument that enables accurate control and reproducibility, demonstrating its suitability for time-efficient cryo-EM structure determination.

Type VII secretion (T7S) systems, also referred to as ESAT-6 secretion (ESX) systems, are molecular machines that have gained great attention due to their implications in cell homeostasis and in host–pathogen interactions in mycobacteria. The latter include important human pathogens such as Mycobacterium tuberculosis (Mtb), the etiological cause of human tuberculosis, which constitutes a pandemic accounting for more than one million deaths every year. The ESX-5 system is exclusively found in slow-growing pathogenic mycobacteria, where it mediates the secretion of a large family of virulence factors: the PE and PPE proteins. The secretion driving force is provided by EccC5, a multidomain ATPase that operates using four globular cytosolic domains: an N-terminal domain of unknown function (EccC5DUF) and three FtsK/SpoIIIE ATPase domains. Recent structural and functional studies of ESX-3 and ESX-5 systems have revealed EccCDUF to be an ATPase-like fold domain with potential ATPase activity, the functionality of which is essential for secretion. Here, the crystal structure of the MtbEccC5DUF domain is reported at 2.05 Å resolution, which reveals a nucleotide-free structure with degenerated cis-acting and trans-acting elements involved in ATP binding and hydrolysis. This crystallographic study, together with a biophysical assessment of the interaction of MtbEccC5DUF with ATP/Mg2+, supports the absence of ATPase activity proposed for this domain. It is shown that this degeneration is also present in DUF domains from other ESX and ESX-like systems, which are likely to exhibit poor or null ATPase activity. Moreover, based on an in silico model of the N-terminal region of MtbEccC5DUF, it is hypothesized that MtbEccC5DUF is a degenerated ATPase domain that may have retained the ability to hexamerize. These observations draw attention to DUF domains as structural elements with potential implications in the opening and closure of the membrane pore during the secretion process via their involvement in inter-protomer interactions.

Crystal polymorphism serves as a strategy to study the conformational flexibility of proteins. However, the relationship between protein crystal packing and protein conformation often remains elusive. In this study, two distinct crystal forms of a green fluorescent protein variant, NowGFP, are compared: a previously identified monoclinic form (space group C2) and a newly discovered ortho­rhombic form (space group P212121). Comparative analysis reveals that both crystal forms exhibit nearly identical linear assemblies of NowGFP molecules interconnected through similar crystal contacts. However, a notable difference lies in the stacking of these assemblies: parallel in the monoclinic form and perpendicular in the orthorhombic form. This distinct mode of stacking leads to different crystal contacts and induces structural alteration in one of the two molecules within the asymmetric unit of the orthorhombic crystal form. This new conformational state captured by orthorhombic crystal packing exhibits two unique features: a conformational shift of the β-barrel scaffold and a restriction of pH-dependent shifts of the key residue Lys61, which is crucial for the pH-dependent spectral shift of this protein. These findings demonstrate a clear connection between crystal packing and alternative conformational states of proteins, providing insights into how structural variations influence the function of fluorescent proteins.

The large Bunyavirales order includes several families of viruses with a segmented ambisense (−) RNA genome and a cytoplasmic life cycle that starts by synthesizing viral mRNA. The initiation of transcription, which is common to all members, relies on an endonuclease activity that is responsible for cap-snatching. In La Crosse virus, an orthobunyavirus, it has previously been shown that the cap-snatching endonuclease resides in the N-terminal domain of the L protein. Orthobunyaviruses are transmitted by arthropods and cause diseases in cattle. However, California encephalitis virus, La Crosse virus and Jamestown Canyon virus are North American species that can cause encephalitis in humans. No vaccines or antiviral drugs are available. In this study, three known Influenza virus endonuclease inhibitors (DPBA, L-742,001 and baloxavir) were repurposed on the La Crosse virus endonuclease. Their inhibition was evaluated by fluorescence resonance energy transfer and their mode of binding was then assessed by differential scanning fluorimetry and microscale thermophoresis. Finally, two crystallographic structures were obtained in complex with L-742,001 and baloxavir, providing access to the structural determinants of inhibition and offering key information for the further development of Bunyavirales endonuclease inhibitors.

A new polymorph of 1,3-diacetylpyrene has been obtained from its melt and thoroughly characterized using single-crystal X-ray diffraction, steady-state UV–Vis spectroscopy and periodic density functional theory calculations. Experimental studies covered the temperature range from 90 to 390 K and the pressure range from atmospheric to 4.08 GPa. Optimal sample placement in a diamond anvil cell according to our previously presented methodology ensured over 80% data coverage up to 0.8 Å for a monoclinic sample. Unrestrained Hirshfeld atom refinement of the high-pressure crystal structures was successful and anharmonic behavior of carbonyl oxygen atoms was observed. Unlike the previously characterized polymorph, the structure of 2°AP-β is based on infinite π-stacks of antiparallel 2°AP molecules. 2°AP-β displays piezochromism and piezofluorochromism which are directly related to the variation in interplanar distances within the π-stacking. The importance of weak intermolecular interactions is reflected in the substantial negative thermal expansion coefficient of −55.8 (57) MK−1 in the direction of C—H⋯O interactions.

3D electron diffraction (3DED) is increasingly employed to determine molec­ular and crystal structures from micro-crystals. Indomethacin is a well known, marketed, small-molecule non-steroidal anti-inflammatory drug with eight known polymorphic forms, of which four structures have been elucidated to date. Using 3DED, we determined the structure of a new ninth polymorph, σ, found within an amorphous solid dispersion, a product formulation sometimes used for active pharmaceutical ingredients with poor aqueous solubility. Subsequently, we found that σ indomethacin can be produced from direct solvent evaporation using di­chloro­methane. These results demonstrate the relevance of 3DED within drug development to directly probe product formulations.

SnGe4N4O4 was synthesized at high pressure (16 and 20 GPa) and high temperature (1200 and 1500°C) in a large-volume press. Powder X-ray diffraction experiments using synchrotron radiation indicate that the derived samples are mixtures of known and unknown phases. However, the powder X-ray diffraction patterns are not sufficient for structural characterization. Transmission electron microscopy studies reveal crystals of several hundreds of nanometres in size with different chemical composition. Among them, crystals of a previously unknown phase with stoichiometry SnGe4N4O4 were detected and investigated using automated diffraction tomography (ADT), a three-dimensional electron diffraction method. Via ADT, the crystal structure could be determined from single nanocrystals in space group P63mc, exhibiting a nolanite-type structure. This was confirmed by density functional theory calculations and atomic resolution scanning transmission electron microscopy images. In one of the syntheses runs a rhombohedral 6R polytype of SnGe4N4O4 could be found together with the nolanite-type SnGe4N4O4. The structure of this polymorph was solved as well using ADT.

Ion radii are derived here from the characteristic (grand mean) bond lengths for (i) 135 ions bonded to oxygen in 459 configurations (on the basis of coordination number) using 177 143 bond lengths extracted from 30 805 ordered coordination polyhedra from 9210 crystal structures; and (ii) 76 ions bonded to nitro­gen in 137 configurations using 4048 bond lengths extracted from 875 ordered coordination polyhedra from 434 crystal structures. There are two broad categories of use for ion radii: (1) those methods which use the relative sizes of cation and anion radii to predict local atomic arrangements; (2) those methods which compare the radii of different cations (or the radii of different anions) to predict local atomic arrangements. There is much uncertainty with regard to the relative sizes of cations and anions, giving rise to the common failure of type (1) methods, e.g. Pauling's first rule which purports to relate the coordination adopted by cations to the radius ratio of the constituent cation and anion. Conversely, type (2) methods, which involve comparing the sizes of different cations with each other (or different anions with each other), can give very accurate predictions of site occupancies, physical properties etc. Methods belonging to type (2) can equally well use the characteristic bond lengths themselves (from which the radii are derived) in place of radii to develop correlations and predict crystal properties. Extensive quantum-mechanical calculations of electron density in crystals in the literature indicate that the radii of both cations and anions are quite variable with local arrangement, suggesting significant problems with any use of ion radii. However, the dichotomy between the experimentally derived ion radii and the quantum-mechanical calculations of electron density in crystals is removed by the recognition that ion radii are pr­oxy variables for characteristic bond lengths in type (2) relations.

A polycrystalline sample LuCrO3 has been characterized by neutron powder diffraction (NPD) and magnetization measurements. Its crystal structure has been Rietveld refined from NPD data in space group Pnma; this perovskite contains strongly tilted CrO6 octahedra with extremely bent Cr—O—Cr superexchange angles of ∼142°. The NPD data show that below Néel temperature (TN ≃ 131 K), the magnetic structure can be defined as an A-type antiferromagnetic arrangement of Cr3+ magnetic moments, aligned along the b axis, with a canting along the c axis. A noticeable magneto­strictive effect is observed in the unit-cell parameters and volume upon cooling down across TN. The AC magnetic susceptibility indicates the onset of magnetic ordering below 112.6 K; the magnetization isotherms below TN show a nonlinear behaviour that is associated with the described canting of the Cr3+ magnetic moments. From the Curie–Weiss law, the effective moment of the Cr3+ sublattice is found to be μeff = 3.55 μB (calculated 3.7 μB) while the ΘCW parameter yields a value of −155 K, indicating antiferromagnetic interactions. There is a conspicuous increase of TN upon the application of external pressure, which must be due to shortening of the Cr—O bond length under compression that increases the orbital overlap integral.

Magnetic materials featuring triangular arrangements of spins are frequently investigated as platforms hosting magnetic frustration. Hexagonal perovskites with ordered vacancies serve as excellent candidates for two-dimensional triangular magnetism due to the considerable separation of the magnetic planes. In this work, the effects of chemical pressure on the ferromagnetic ground state of Ba2La2NiW2O12 by substitution of Ba2+ with Sr2+ to produce Sr2La2NiW2O12 are investigated. The two materials are characterized using synchrotron-based XRD, XANES and EXAFS in addition to magnetometry in order to correlate their crystal structures and magnetic properties. Both materials form in space group R3, yet as a result of the enhanced bending of key bond angles due to the effects of chemical pressure, the TC value of the magnetic Ni2+ sublattice is reduced from ∼6 K in Ba2La2NiW2O12 to 4 K in Sr2La2NiW2O12.

Two new copper dimers, namely, bis­(dimethyl sulfoxide)­tetra­kis­(μ-pyrene-1-carboxyl­ato)dicopper(Cu—Cu), [Cu2(C17H9O2)4(C2H6OS)2] or [Cu2(pyr-COO−)4(DMSO)2] (1), and bis­(di­methyl­formamide)­tetra­kis­(μ-pyrene-1-carboxyl­ato)dicopper(Cu—Cu), [Cu2(C17H9O2)4(C3H7NO)2] or [Cu2(pyr-COO−)4(DMF)2] (2) (pyr = pyrene), were synthesized from the reaction of pyrene-1-carb­oxy­lic acid, copper(II) nitrate and tri­ethyl­amine from solvents DMSO and DMF, respectively. While 1 crystallized in the space group Poverline{1}, the crystal structure of 2 is in space group P21/n. The Cu atoms have octa­hedral geometries, with four oxygen atoms from carboxyl­ate pyrene ligands occupying the equatorial positions, a solvent mol­ecule coordinating at one of the axial positions, and a Cu⋯Cu contact in the opposite position. The packing in the crystal structures exhibits π–π stacking inter­actions and short contacts through the solvent mol­ecules. The Hirshfeld surfaces and two-dimensional fingerprint plots were generated for both compounds to better understand the inter­molecular inter­actions and the contribution of heteroatoms from the solvent ligands to the crystal packing. In addition, a Cu2+/Cu1+ quasi-reversible redox process was identified for compound 2 using cyclic voltammetry that accounts for a diffusion-controlled electron-donation process to the Cu dimer.

The title compound, C20H16N2O2, is composed of two monosubstituted benzene rings and one benzimidazole unit. The benzimidazole moiety subtends dihedral angles of 46.16 (7) and 77.45 (8)° with the benzene rings, which themselves form a dihedral angle of 54.34 (9)°. The crystal structure features O—H⋯N and O—H⋯O hydrogen-bonding inter­actions, which together lead to the formation of two-dimensional hydrogen-bonded layers parallel to the (101) plane. In addition, π–π inter­actions also contribute to the crystal cohesion. Hirshfeld surface analysis indicates that the most significant contacts in the crystal packing are: H⋯H (47.5%), O⋯H/H⋯O (12.4%), N⋯H/H⋯N (6.1%), C⋯H/H⋯C (27.6%) and C⋯C (4.6%).

A new lanthanide coordination polymer, poly[[tri­aqua­bis­(μ4-phthalato)(μ3-pyridine-2,5-di­carboxyl­ato)dipraseodymium] monohydrate], {[Pr2(C7H3NO4)2(C8H4O4)(H2O)3]·H2O}n or {[Pr2(phth)2(pydc)(H2O)3]·H2O}n, (pydc2− = pyridine-2,5-di­carboxyl­ate and phth2− = phthalate) was synthesized and characterized, revealing the structure to be an assembly of di-periodic {Pr2(pydc)(phth)2(H2O)3}n layers. Each layer is built up by edge-sharing {Pr2N2O14} and {Pr2O16} dimers, which are connected through a new coordin­ation mode of pydc2− and phth2−. These layers are stabilized by inter­nal hydrogen bonds and π–π inter­actions. In addition, a three-dimensional supra­molecular framework is built by inter­layer hydrogen-bonding inter­actions involving the non-coordinated water mol­ecule. Thermogravimetric analysis shows that the title compound is thermally stable up to 400°C.

Lanthanide-containing materials are of inter­est in the field of crystal engin­eering because of their unique properties and distinct structure types. In this context, a new samarium–sodium heterometallic coordination polymer, poly[tetra­kis­(μ2-2-formyl-6-meth­oxy­phenolato)samarium(III)sodium(I)], {[SmNa(C8H7O3)4]·solvent}n (Sm-1), was synthesized and crystallized via slow evaporation from a mixture of ethanol and aceto­nitrile. The compound features alternating SmIII and NaI ions, which are linked by ortho-vanillin (o-vanillin) ligands to form a mono-periodic chain-like coordination polymer. The chains propagate along the [001] direction. Residual electron density of disordered solvent mol­ecules in the void space could not be reasonably modeled, thus the SQUEEZE function was applied. The structural, vibrational, and optical properties are reported.

A CuII coordination polymer, catena-poly[[[aqua­copper(II)]-bis­(μ-4-amino­benz­o­ato)-κ2N:O;κ2O:N] monohydrate], {[Cu(pABA)2(H2O)]·H2O}n (pABA = p-amino­benzoate, C7H4NO2−), was synthesized and characterized. It exhibits a one-dimensional chain structure extended into a three-dimensional supra­molecular assembly through hydrogen bonds and π–π inter­actions. While the twinned crystal shows a metrically ortho­rhom­bic lattice and an apparent space group Pbcm, the true symmetry is monoclinic (space group P2/c), with disordered Cu atoms and mixed roles of water mol­ecules (aqua ligand/crystallization water). The luminescence spectrum of the complex shows an emission at 345 nm, cf. 349 nm for pABAH.

Three new 1H-indole derivatives, namely, 2-(bromo­meth­yl)-3-methyl-1-(phenyl­sulfon­yl)-1H-indole, C16H14BrNO2S, (I), 2-[(E)-2-(2-bromo-5-meth­oxy­phen­yl)ethen­yl]-3-methyl-1-(phenyl­sulfon­yl)-1H-indole, C24H20BrNO3S, (II), and 2-[(E)-2-(2-bromo­phen­yl)ethen­yl]-3-methyl-1-(phenyl­sulfon­yl)-1H-indole, C23H18BrNO2S, (III), exhibit nearly orthogonal orientations of their indole ring systems and sulfonyl-bound phenyl rings. Such conformations are favourable for inter­molecular bonding involving sets of slipped π–π inter­actions between the indole systems and mutual C—H⋯π hydrogen bonds, with the generation of two-dimensional monoperiodic patterns. The latter are found in all three structures, in the form of supra­molecular columns with every pair of successive mol­ecules related by inversion. The crystal packing of the compounds is additionally stabilized by weaker slipped π–π inter­actions between the outer phenyl rings (in II and III) and by weak C—H⋯O, C—H⋯Br and C—H⋯π hydrogen bonds. The structural significance of the different kinds of inter­actions agree with the results of a Hirshfeld surface analysis and the calculated inter­action energies. In particular, the largest inter­action energies (up to −60.8 kJ mol−1) are associated with pairing of anti­parallel indole systems, while the energetics of weak hydrogen bonds and phenyl π–π inter­actions are comparable and account for 13–34 kJ mol−1.

The title compound, [Co(NCS)2(C6H7N)4] or Co(NCS)2(4-methyl­pyridine)4, was prepared by the reaction of Co(NCS)2 with 4-methyl­pyridine in water and is isotypic to one of the polymorphs of Ni(NCS)2(4-methyl­pyridine)4 [Kerr & Williams (1977). Acta Cryst. B33, 3589–3592 and Soldatov et al. (2004). Cryst. Growth Des. 4, 1185–1194]. Comparison of the experimental X-ray powder pattern with that calculated from the single-crystal data proves that a pure phase has been obtained. The asymmetric unit consists of one CoII cation, two crystallographically independent thio­cyanate anions and four independent 4-meth­yl­pyridine ligands, all located in general positions. The CoII cations are sixfold coordinated to two terminally N-bonded thio­cyanate anions and four 4-methyl­pyridine coligands within slightly distorted octa­hedra. Between the complexes, a number of weak C—H⋯N and C—H⋯S contacts are found. This structure represent a polymorphic modification of Co(NCS)2(4-methyl­pyridine)4 already reported in the CCD [Harris et al. (2003). NASA Technical Reports, 211890]. In contrast to this form, the crystal structure of the new polymorph shows a denser packing, indicating that it is thermodynamically stable at least at low temperatures. Thermogravimetric and differential thermoanalysis reveal that the title compound starts to decomposes at about 100°C and that the coligands are removed in separate steps without any sign of a polymorphic transition before decomposition.

The title compound, bis­[μ-2,2'-(4H-1,2,4-triazole-3,5-di­yl)di­acetato]­bis­[di­aqua­copper(II)] dihydrate, [Cu2(C6H5N3O4)2(H2O)4]·2H2O, is a dinuclear octa­hedral CuII triazole-based complex. The central copper atoms are hexa-coordinated by two nitro­gen atoms in the equatorial positions, two equatorial oxygen atoms of two carboxyl­ate substituents in position 3 and 5 of the 1,2,4-triazole ring, and two axial oxygen atoms of two water mol­ecules. Two additional solvent water mol­ecules are linked to the title mol­ecule by O—H⋯N and O⋯H—O hydrogen bonds. The crystal structure is built up from the parallel packing of discrete supra­molecular chains running along the a-axis direction. Hirshfeld surface analysis suggests that the most important contributions to the surface contacts are from H⋯O/O⋯H (53.5%), H⋯H (28.1%), O⋯O (6.3%) and H⋯C/C⋯H (6.2%) inter­actions. The crystal studied was twinned by a twofold rotation around [100].

Reaction of copper(I)chloride with 2,3-di­methyl­pyrazine in ethanol leads to the formation of the title compound, poly[[μ-chlorido-μ-(2,3-di­methyl­pyrazine)-copper(I)] ethanol hemisolvate], {[CuCl(C6H8N2)]·0.5C2H5OH}n or CuCl(2,3-di­methyl­pyrazine) ethanol hemisolvate. Its asymmetric unit consists of two crystallographically independent copper cations, two chloride anions and two 2,3-di­methyl­pyrazine ligands as well as one ethanol solvate mol­ecule in general positions. The ethanol mol­ecule is disordered and was refined using a split model. The methyl H atoms of the 2,3-di­methyl­pyrazine ligands are also disordered and were refined in two orientations rotated by 60° relative to each other. In the crystal structure, each copper cation is tetra­hedrally coordinated by two N atoms of two bridging 2,3-di­methyl­pyrazine ligands and two μ-1,1-bridg­ing chloride anions. Each of the two copper cations are linked by pairs of bridging chloride anions into dinuclear units that are further linked into layers via bridging 2,3-di­methyl­pyrazine coligands. These layers are stacked in such a way that channels are formed in which the disordered solvent mol­ecules are located. The topology of this network is completely different from that observed in the two polymorphic modifications of CuCl(2,3-di­methyl­pyrazine) reported in the literature [Jess & Näther (2006). Inorg. Chem. 45, 7446–7454]. Powder X-ray diffraction measurements reveal that the title compound is unstable and transforms immediately into an unknown crystalline phase.

BioXTAS RAW is a free open-source program for reduction, analysis and modelling of biological small-angle scattering data. Here, the new developments in RAW version 2 are described. These include improved data reduction using pyFAI; updated automated Guinier fitting and Dmax finding algorithms; automated series (e.g. size-exclusion chromatography coupled small-angle X-ray scattering or SEC-SAXS) buffer- and sample-region finding algorithms; linear and integral baseline correction for series; deconvolution of series data using regularized alternating least squares (REGALS); creation of electron-density reconstructions using electron density via solution scattering (DENSS); a comparison window showing residuals, ratios and statistical comparisons between profiles; and generation of PDF reports with summary plots and tables for all analysis. Furthermore, there is now a RAW API, which can be used without the graphical user interface (GUI), providing full access to all of the functionality found in the GUI. In addition to these new capabilities, RAW has undergone significant technical updates, such as adding Python 3 compatibility, and has entirely new documentation available both online and in the program.

Macromolecular crystallography contributes significantly to understanding diseases and, more importantly, how to treat them by providing atomic resolution 3D structures of proteins. This is achieved by collecting X-ray diffraction images of protein crystals from important biological pathways. Spotfinders are used to detect the presence of crystals with usable data, and the spots from such crystals are the primary data used to solve the relevant structures. Having fast and accurate spot finding is essential, but recent advances in synchrotron beamlines used to generate X-ray diffraction images have brought us to the limits of what the best existing spotfinders can do. This bottleneck must be removed so spotfinder software can keep pace with the X-ray beamline hardware improvements and be able to see the weak or diffuse spots required to solve the most challenging problems encountered when working with diffraction images. In this paper, we first present Bragg Spot Detection (BSD), a large benchmark Bragg spot image dataset that contains 304 images with more than 66 000 spots. We then discuss the open source extensible U-Net-based spotfinder Bragg Spot Finder (BSF), with image pre-processing, a U-Net segmentation backbone, and post-processing that includes artifact removal and watershed segmentation. Finally, we perform experiments on the BSD benchmark and obtain results that are (in terms of accuracy) comparable to or better than those obtained with two popular spotfinder software packages (Dozor and DIALS), demonstrating that this is an appropriate framework to support future extensions and improvements.

Characterization of crystallization processes in situ is of great importance to furthering knowledge of how nucleation and growth processes direct the assembly of organic and inorganic materials in solution and, critically, understanding the influence that these processes have on the final physico-chemical properties of the resulting solid form. With careful specification and design, as demonstrated here, it is now possible to bring combined X-ray diffraction and Raman spectroscopy, coupled to a range of fully integrated segmented and continuous flow platforms, to the laboratory environment for in situ data acquisition for timescales of the order of seconds. The facility used here (Flow-Xl) houses a diffractometer with a micro-focus Cu Kα rotating anode X-ray source and a 2D hybrid photon-counting detector, together with a Raman spectrometer with 532 and 785 nm lasers. An overview of the diffractometer and spectrometer setup is given, and current sample environments for flow crystallization are described. Commissioning experiments highlight the sensitivity of the two instruments for time-resolved in situ data collection of samples in flow. Finally, an example case study to monitor the batch crystallization of sodium sulfate from aqueous solution, by tracking both the solute and solution phase species as a function of time, highlights the applicability of such measurements in determining the kinetics associated with crystallization processes. This work illustrates that the Flow-Xl facility provides high-resolution time-resolved in situ structural phase information through diffraction data together with molecular-scale solution data through spectroscopy, which allows crystallization mechanisms and their associated kinetics to be analysed in a laboratory setting.

This article presents a web-based framework to build a database without in-depth programming knowledge given a set of CIF dictionaries and a collection of CIFs. The framework consists of two main elements: the public site that displays the information contained in the CIFs in an ordered manner, and the restricted administrative site which defines how that information is stored, processed and, eventually, displayed. Thus, the web application allows users to easily explore, filter and access the data, download the original CIFs, and visualize the structures via JSmol.

Bruce Timm's DC Comics animated universe, beginning with "Batman: The Animated Series" and continuing with "Superman," "Batman Beyond," "Justice League," "Justice League Unlimited" and more, remains one of the most beloved and critically acclaimed animated runs in existence. The run was so idenified with the producer that it was sometimes called the Timmverse, but the last show in that continuity ended in 2006 and Timm officially stepped down from working with DC animation in 2013.

Now Timm is back. He's providing a darker take than the optimistic world he became known for in "Justice League: Gods and Monsters," a three-part digital series launching spring 2015 that will be tied in with a full-length animated film that comes out later that year, according to a press release.

Timm's also re-teaming with Alan Burnett, who worked with Timm on "Batman: The Animated Series." It's part of DC Comics' efforts to set up their new film "Batman v Superman: Dawn of Justice," which hits in 2016, with the full Justice League film set for 2018.

DC Comics as a whole has been moving in a darker direction with Christopher Nolan's Batman trilogy, the "Man of Steel" reboot of Superman and a more serious direction in many of its comic books. The company has followed in its tradition of epic storytelling, passing on the quips Marvel has popularized in films from "Iron Man" to "Guardians of the Galaxy."

It's yet to be seen if Timm can recapture any of the magic from his classic cartoons, but there's reason to be optimistic for the creator of the series that introduced fan favorite Joker sidekick Harley Quinn, created a new origin for Mr. Freeze that cemented the character in the Batman mythos and led the team reimagining numerous characters in an iconic, broadly appealing way.

If you want to catch up on Timm's legacy, his previous two Justice League series are available on Netflix and Amazon Prime, along with "Batman Beyond," while the Batman and Superman animated series are available on Amazon Prime.

Timm also recently produced a short for the 75th anniversary of Batman called "Strange Days," setting the character in the retro world of the serialized pulp storytelling from the time Batman was originally created. You can watch that below:

The new Queen compilation "Queen Forever" includes three previously unreleased tracks, but the one that has people talking is a collaboration between two legends: Freddie Mercury and Michael Jackson.

The new song, "There Must Be More to Life Than This," was an unfinished track recorded during studio sessions for the 1981 Queen album "Hot Space," according to a press release on the new compilation. Queen also looked at the song for 1984's "The Works," but still don't go with it — the song finally landed, sans Jackson, on 1985's Mercury solo album "Mr. Bad Guy."

Listen to the new version of the song here:

Michael Jackson/Queen Soundcloud

Listen to the originally recorded version of the Queen/Jackson collaboration below:

Michael Jackson/Queen collabo

The new version was produced by William Orbit, who also did a remix of the song.

"Hearing Michael Jackson's vocals was stirring. So vivid, so cool, and poignant, it was like he was in the studio singing live. With Freddie's vocal solo on the mixing desk, my appreciation for his gift was taken to an even higher level," Orbit said in a press release.

The song is a call for peace, talking human rights in a general way. It almost didn't end up on the album — Queen's Brian May said that working with the Jackson family and Jackson's estate was like "wading through glue," according to Philly.com, but the track ended up making the cut.

The album also includes unreleased song "Let Me In Your Heart Again" and a new version of a song Mercury released solo, an acoustic take on "Love Kills." "Let Me In Your Heart Again" was previously recorded and released by May's wife Anita Dobson.

"Freddie sounds as fresh as yesterday," May said at a press conference while the new compilation was in the works.

American Salars Lithium Inc. (USLI:CSE; USLIF:OTC; Z3P:FWB; A3E2NY:WKN) announced it is strategically reviewing multiple Canadian mineral properties prospective for lithium close to recent pegmatite, or hard-rock, lithium discoveries.

The first project under review is about 150 kilometers north of Matagami, where there is a small town with a rail link to much of James Bay, and has the Billy Diamond Highway running through it.

American Salars said it's close to Q2 Metals Corp. (QTWOTSX-V; OTCQB:QUEXF) Cisco Lithium Project, which reported drill intercepts of 215.6 meters at 1.69% Li2O, including 64.6 meters at 2.29%. Also nearby are multiple projects owned by Sayona Mining Ltd (SYA:ASX), which is currently Canada's only lithium producer.

"Our primary objective remains the acquisition of low-cost lithium brine assets in Argentina while expanding our existing NI 43-101 lithium brine resources," said Chief Executive Officer and Director R. Nick Horsley. "We believe that Quebec-based hard rock lithium assets can now be acquired at deeply discounted prices and advanced with critical mineral flow through financing incentives in anticipation of the next lithium rally."

American Salars said it is reviewing additional projects close to Sayona, which will be subject to disclosure "once due diligence is completed and a deal is completed." The company stressed that its "intent to acquire property and current strategic review does not necessarily mean that a transaction will occur."

Current Assets Also in Argentina, Nevada

The company's existing portfolio of lithium deposits includes two NI 43-101-compliant Inferred Mineral Resource Estimates (MREs) consisting of 457,000 tonnes of lithium carbonate equivalent (LCE) at the Candela 2 Lithium Brine Project and a shared MRE at the Pocitos 1 Lithium Brine Project consisting of 760,000 tonnes LCE. The Pocitos MRE is shared with the neighboring Pocitos 2 property, which is not under contract or owned by American Salars, but the company noted that none of the drilling that makes up a partial basis for the MRE took place on the Pocitos 2 block. Both brine projects are located in Salta Province, Argentina.

Major mining company Rio Tino recently invested in Argentina by acquiring Argentina lithium producer Arcadium Lithium for US$6.7 billion, making the company the world's third-largest lithium producer.

American Salars recently released assay results from soil samples collected during its Phase 1 exploration program at its 100%-owned Black Rock South lithium project close to Tesla's Gigafactory in Nevada.

Technical Analyst Clive Maund wrote that the entire "San Emidio Desert basin is a highly prospective lithium exploration zone and is about 38 kilometers long and up to 11 kilometers wide at the widest point, with the central playa measuring about 8.5 kilometers north-south and 4.5 kilometers east-west."

Out of 38 samples, 33 recorded lithium concentration of more than 100 parts per million (ppm) or higher, the company said. The highest grade was 180.5 ppm with an average grade of 131 ppm across the 33 samples of the surface of the property.

Technical Analyst Clive Maund wrote that the entire "San Emidio Desert basin is a highly prospective lithium exploration zone and is about 38 kilometers long and up to 11 kilometers wide at the widest point, with the central playa measuring about 8.5 kilometers north-south and 4.5 kilometers east-west."*

"After a massive speculative runup in 2020 and especially in 2021, the lithium price fell victim to a severe bear market that ran from mid-2022 through the end of 2023," Maund continued. "By the end of last year, this bear market had exhausted itself, and a basing process began that has continued up to the present."

In addition to its location near the Gigafactory, Black Rock South is 93 miles southwest of Thacker and 215 miles northwest of the United States' only producing lithium mine, the Silver Peak lithium brine mine owned by Albermarle.

The Catalyst: More Growth Coming

Lithium is critical in the energy transition for its use in batteries for EVs and other applications. It also is used in electronics, medicine and other industries.

According to a report by Grand View Research, market size for the metal was estimated at US$31.75 billion last year and is projected to grow at a compound annual growth rate (CAGR) of 17.7% from this year through 2030.

"The automotive application segment is expected to witness substantial growth, driven by stringent regulations imposed by government bodies on ICE automakers to reduce carbon dioxide emissions from vehicles," researchers at Grand View said. "This has shifted the interest of automakers toward producing EVs, which is anticipated to benefit the demand for lithium and related products."

EVs and battery storage primarily will fuel future growth of the lithium market, Marin Katusa of Katusa Research wrote recently. He pointed out that all major electric vehicle batteries require lithium, about 1.55 pounds per kilowatt hour of battery capacity, on average.

"I think the data speaks for itself that there's more growth and opportunity on the horizon," Katusa wrote.

According to FastMarkets, prices for the metal have fallen over the past 18 months as weaker demand improved availability. However, this "has done little to deter the appetite for expansion," raw battery materials analyst Jordan Roberts told the publication.[OWNERSHIP_CHART-11095]

The consensus among market analysts points to a recovery in lithium prices in the fourth quarter of 2024, Fastmarkets reported.

"This optimism is grounded in expectations of increased activity . . . to meet end of year targets, strong battery production seen in March and April finally filtering through upstream and low inventory levels necessitating restocking," the website noted.

Ownership and Share Structure

American Salars said it has 28.8 million shares outstanding and 5.5 million warrants, according to the company.

As for insiders, the CEO Horsley owns about 1.83 million, or about 7.37%, with 4666,666 warrants. Strategic investor Hillcrest Merchant Partners owns 1 million shares or 4.03%. There are no institutional investors, and the rest is retail.

Its market cap is CA$4.79 million. It trades in a 52-week range of CA$0.45 and CA$0.08.

Atlas Lithium Corp. (ATLX:NASDAQ) announced that it has received the operational permit for its Neves Project. This marks a significant milestone for the company's ambitions in lithium production. The permit, approved by the Minas Gerais government in Brazil, allows Atlas Lithium to assemble and operate its processing plant, develop open-pit mining operations, and produce lithium concentrate. The unanimously voted October 25 decision officially progressed with the publication in Minas Gerais' government gazette the following day.

The Neves Project permit, a comprehensive triphasic license (LI/LP/LO), enables a more streamlined development, encompassing initial, installation, and operating permissions.

"Permitting is widely considered the most critical risk in any mining project," said Atlas Lithium CEO Marc Fogassa in the news release. The company's success in obtaining this permit underscores its commitment to sustainable, responsible operations in Brazil's "Lithium Valley."

The Allure of The Lithium Market

According to Visual Capitalist on September 29, battery metal prices have recently "struggled as a surge in new production overwhelmed demand." However, with battery demand projected to increase ninefold by 2040, companies positioned to produce high-quality lithium concentrate, such as Atlas Lithium, are likely to see enhanced market relevance as the demand trajectory for lithium-ion batteries strengthens significantly over the coming decades.

Jake Sekelsky from Alliance Global Partners reaffirmed his "Buy" rating for Atlas Lithium, setting a price target of US$45.00.

As Forbes wrote on October 8, 2024, recent industry dynamics have shown that "a 50% rise in the price of a downtrodden lithium producer has boosted investor hopes that a revival in the battery metal is possible after two grim years of oversupply and low prices."

This improvement in lithium prices reflects a broader trend that may positively impact companies like Atlas Lithium, whose operational progress aligns with the gradual sector recovery. The recent permitting for Atlas Lithium's Neves Project positions it to capitalize on these trends as it advances its lithium production capabilities.

On that same day, Barry Dawes of Martin Place Securities commented that "the lithium market is showing strong signs of upturn," anticipating "lithium shortages post-2027." This outlook emphasizes the sector's potential for heightened demand and supply constraints, which is particularly beneficial for projects advancing toward production. Atlas Lithium's strategy, which includes a modular processing plant and environmentally responsible operations, underscores the company's readiness to meet this anticipated demand.

What's Driving Atlas Forward?

Atlas Lithium's Neves Project's recent permit positions the company to advance toward its production goals with key environmental and operational clearances in place. According to the company's September 2024 investor presentation, this approval aligns with an expedited project timeline and enhances the company's potential to become a low-cost lithium concentrate producer. With Brazil's favorable mining conditions and Atlas Lithium's established partnerships with Tier 1 global companies, the Neves Project is poised for cost-effective operations and market alignment.

Atlas's modular processing plant, currently in the final pre-shipment stage, also demonstrates a strategic focus on efficiency and ESG standards. This advanced plant is set for rapid assembly and installation. It reflects Atlas Lithium's intention to minimize environmental impact and expedite production ramp-up, contributing to a streamlined path toward production in Brazil's burgeoning lithium sector.

Analysts On Atlas

Jake Sekelsky from Alliance Global Partners reaffirmed his "Buy" rating for Atlas Lithium, setting a price target of US$45.00. He described the recent operational permit issuance for the Neves Project as a "significant de-risking event," emphasizing that this milestone positions the project to move forward with construction and operations. Sekelsky highlighted that the approval "marks the final step in the permitting process" and grants Atlas Lithium the authorization to proceed with assembling its processing facility and initiating open-pit mining operations. This development aligns with a clear production path, with Sekelsky noting that the project is now at "shovel-ready status," a critical advancement toward fulfilling Atlas Lithium's strategic objectives. [OWNERSHIP_CHART-11040]

Sekelsky also pointed to the current market environment for lithium, expressing optimism regarding "signs of an upcoming recovery" in lithium prices. He interpreted recent merger and acquisition activities within the sector, including other acquisitions in Brazil's Lithium Valley, as indicators that larger players anticipate a rebound. Sekelsky remarked that this resurgence could benefit advanced hard-rock lithium projects, such as Neves, which "continue to command attention from potential suitors."

Ownership and Share Structure

About 34% of Atlas Lithium is owned by management and insiders. About 11% of the shareholders are institutional. Strategic partners hold another 12%. The rest, about 43%, is retail.

Top shareholders include Waratah Capital Advisors Ltd. with 4.34%, Mitsui & Co. Ltd. with 12.27%, and Candace Shira Associates LLC with 1.39%, according to Reuters.

Its market cap is about US$165 million. It trades in a 52-week range of US$34 and US$6.25.

Revolve Renewable Power Corp. (TSXV:REVV; OTCQB:REVVF) released its strongest financial results since going public in 2022, those for fiscal year 2024 (FY24) ended June 30, 2024, the company announced in a news release.

"FY24 marked significant progress for the company as it continues its transition to an owner and operator of renewable energy projects, incorporating a focus on building long-term recurring revenues and cash flow for the business," the release noted.

This company, headquartered in British Columbia, develops utility-scale solar, wind, hydro, and battery storage projects in North America. The Revolve Renewable Business Solutions division installs and operates sub-20-megawatt, behind-the-meter distributed generation assets.

FY24 revenue of US$6.7 million (US$6.7M) exceeded guidance by 35% and surpassed FY23 revenue by 509%. Significant contributors to total revenue for this latest fiscal year were deferred revenues and milestone payments of US$4.25M from the sale of the Bouse and Parker projects to ENGIE. Completion of the WindRiver Power Corp. acquisition in February added $671,738 of total revenue. In the future, WindRiver business is projected to generate recurring revenue of US$1.8M on a 12-month basis.

Adjusted EBITDA in FY24 also was up year over year (YOY), at US$2.7M versus US$1.5M of guidance and (US$2.1M) in FY23.

The gross margin in FY24 was strong at 96%. This was due to increased recurring revenues from the distributed generation portfolio, low operating costs of the rooftop solar projects therein, the addition of operating utility-scale projects in Canada, and sale proceeds from utility-scale projects in the U.S.

FY24 resulted in a net income of US$2.6M, whereas FY23 saw a net loss of US$2.3M.

As for the balance sheet, at FY24's end, Revolve had US$3.2M in cash. Total liabilities were US$10M, up from US$2.6M in FY23 due to nonrecourse debt taken on via the WindRiver acquisition plus additional loans granted by RE Royalties Ltd., a Canadian royalty finance company, throughout FY24.

Operational Progress Made

Operationally, in FY24, according to the release, Revolve generated 8,048,729 kilowatt-hours (8,048,729 kWh) of renewable energy, up 397% from 1,618,456 kWH the year before. The main drivers were continuing output from the company's operational distributed generation portfolio and power produced at the Box Springs wind farm.

During the 15 months between July 1, 2023, and Oct. 31, 2024, Revolve added of 76.1 megawatts (76.1 MW) net of development hydro projects in Canada through the WindRiver acquisition and 480 MW of new greenfield development projects in Canada and the U.S. These took the total of Revolve's utility-scale projects under development to 3,015 MW.

The company made significant progress on its 20 megawatt (20 MW)/80 MWh Vernal BESS battery storage project and 49.5 MW Primus wind projects, now in the late stage of development and expected to reach ready-to-build status at the end of 2025 (2025E).

Revolve is still building its two distributed generation assets in Mexico, totaling 3.45 MW. Permitting work continues on the 3 MW CHP project continues, and the final commissioning of the 450-KW-peak rooftop solar project is taking place.

The distributed generation project pipeline remains at about 150 MW, and efforts are ongoing to sign additional power purchase agreements for new projects from it.

Also, Revolve recently announced its acquisition of a 30-MW-peak solar development project in Alberta, Canada, and expects a 20-MW-peak first phase will be ready for construction by 2025E.

Independent Power Producer

Revolve is a revenue-generating, renewable-focused independent power producer formed in 2012 to capitalize on the growing global demand for renewable power, according to its October 2024 Corporate Presentation.

The company began as solely a developer of utility-scale projects, a line of business that provides investors access to higher returns. Currently, the company has two projects under construction, the ones in Mexico and 3,000-plus MW worth of projects in development in Canada, the U.S., and Mexico. To date, Revolve has developed and sold more than 1,550 MW of utility-scale projects and is now targeting 5,000 MW under development.

Today, Revolve is also an owner-operator of renewable energy distribution generation projects that provide recurring revenue and cash flow via long-term power purchase agreements. Currently, the portfolio contains 150-plus MW of generation projects in Canada and Mexico. The company will continue expanding this line of business through organic growth and mergers and acquisitions (M&A) activity.

Revolve's management team has a successful track record in taking renewable energy projects from greenfield to ready-to-build status and in selling them to large operators. Collectively, it has generated about US$23M in revenue historically from the sale of 1,550 MW of development assets and has raised US$10.3M in equity capital.

Significant Sector Growth Forecasted

The transition to net zero emissions continues driving the renewable energy industry after nearly 200 countries at the COP28 UN Climate Change Conference in December 2023 pledged to triple global capacity by the end of this decade. In a report last month, the International Energy Agency (IEA) forecasted global renewable capacity reaching almost 11,000 gigawatts (GW) by then, reflecting 2.7 times growth, falling short of the goal.

Solar Photovoltaic (PV) Power: Of the growth predicted for renewable energy during this period, solar photovoltaic power will make up 80% of it, according to the IEA, due to its increasing economic attractiveness in most countries.

"At the end of this decade, solar PV is set to become the largest renewable source, surpassing both wind and hydropower," the agency wrote. Hydropower currently is the top source worldwide.

Wind Power: Wind power will account for 15% of all forecasted renewable capacity growth, noted the IEA. This sector has suffered recently from macroeconomic factors and supply chain difficulties, but it is expected to recover. Global wind capacity is projected to expand between 2024 and 2029 at double the rate it grew between 2017 and 2023.

"Policy changes concerning auction design, permitting, and grid connection in Europe, the United States, India, and other emerging and developing economies are expected to enhance project bankability and help the wind sector recover from recent financial difficulties," the article noted.

Hydropower: As for hydropower, capacity is continuing to grow consistently, noted the IEA, due primarily to efforts by China, India, Africa and the Association of Southeast Asian Nations region.

In North America, the U.S. is expected to be the biggest market for hydropower, according to Mordor Intelligence. Between 2024 and 2029, the market is forecasted to expand at a compound annual growth rate of 1%, spurred by demand for renewable energy and investments in hydropower plants.

"The technological advancements in efficiency and decrease in the production cost of hydropower projects are expected to create ample opportunity for market players," the article noted.

The Catalysts: Results of Business as Usual

As Revolve continues effecting its growth strategies, numerous potential stock-boosting events should occur, according to its corporate presentation.

Catalysts resulting from ongoing efforts include further M&A transactions, signing additional power purchase agreements, and bringing new distributed generation projects online. wo increasing revenue and cash flow growth.

Specifically, the company reaching its goals of advancing 70 MW of the BESS and Wind projects to ready-to-build status as well as 30 MW of solar in Canada, in 2025. These have the potential to generate material revenue and add value.

Another catalyst is Revolve achieving ready-to-build status for its two wind projects in Mexico, the 103 MW El 24 and the 400 MW Presa Nueva. The company's ultimate goal with these assets is to partner on or sell them. [OWNERSHIP_CHART-10982]

Finally, payments toward the remaining US$45–55M balance still owed to Revolve regarding the ENGIE sale could boost its stock.

Ownership and Share Structure

About 60% of the company is owned by insiders and management, Revolve said.

Top shareholders include Joseph O'Farrell with 13.21%, Roger Norwich with 12.15%, the CEO and Director Stephen Dalton with 6.01%, President and Director Omar Bojorquez with 4.82%, and Jonathan Clare with 1.84%, according to Reuters and the company.

The rest is retail.

Revolve has a market cap of CA$17.96M. It has 63.04M outstanding shares and 38.75M free float traded shares. Its 52-week high and low are CA$0.50 and CA$0.21 per share, respectively.

Jericho Energy Ventures Inc. (JEV:TSX.V; JROOF:OTC; JLM:FRA) has announced a strategic move to spin off its hydrogen solutions platform into a separate entity. The new entity, to be named Hydrogen Technologies Corp. (HTC), was approved by the company's board of directors. The intention is to create two specialized companies focusing on hydrogen technology and traditional energy assets, respectively. Each Jericho Energy shareholder will retain their Jericho shares while receiving shares of the new HTC entity on a pro-rata basis in consideration of the transfer of Jericho's hydrogen assets.

The planned transaction, still subject to regulatory and shareholder approvals, aims to allow both companies to focus on their distinct markets and strategies. Jericho Energy expects this restructuring to enable each company to operate with tailored capital structures and investment plans, positioning them for growth within their specific sectors. The final terms of the spinout will be detailed in a management information circular to be shared with shareholders before they vote on the proposal.

Approval processes for the spinout include a review by the TSX Venture Exchange, shareholder consent, and possibly court approval in British Columbia if the plan proceeds via a formal arrangement. Jericho's CEO, Brian Williamson, noted in the news release, "By separating our hydrogen platform, we can create two agile, focused companies . . . positioning them for long-term growth and success."

Jericho Energy, which will continue trading on the TSX Venture Exchange under the symbol JEV, will retain its traditional oil and gas assets following the separation. The company's annual general meeting on January 15, 2025, may serve as a venue for shareholder approval, or a separate meeting may be scheduled.

Hydrogen Energy and Clean Tech

Energy Storage, in its November 5 report, underscored the growth potential for green hydrogen in the U.S. Supported by the government's US$7 billion Regional Clean Hydrogen Hubs program, this program aimed to boost clean hydrogen production and reduce costs. The report noted that the Mid-Atlantic Hydrogen Hub (MACH2) anticipated large-scale green hydrogen projects, generating over 20,000 jobs and incorporating hydrogen applications across sectors like steel, aviation, and maritime.

On November 6, Reuters reported that despite political shifts, U.S. clean energy momentum continues to be driven by federal tax credits and technology advancements. Renewable energy sources, including hydrogen, were identified as the fastest-growing segments on the power grid, benefiting from initiatives like the Inflation Reduction Act (IRA) and state mandates. Carl Fleming, a partner at McDermott Will & Emery, highlighted that "the jobs and the economic benefits have been so heavy in red states, it's hard to see an administration come in that says we don't like this." Although political challenges might impact renewable sectors like offshore wind, the trajectory of clean energy, including hydrogen, remained strong due to market demand and state-level support.

The International Energy Agency's (IEA) 2024 Global Hydrogen Review reported that global hydrogen demand reached 97 Mt (metric tons) in 2023. This demand was projected to approach 100 Mt in 2024. The IEA highlighted a rising focus on low-emissions hydrogen, particularly for refining and heavy industries. Although new applications in transport and energy storage accounted for less than 1% of global demand, industry interest grew, with chemical, refining, and shipping sectors making strides in contracting low-emissions hydrogen. The IEA also noted substantial investments in electrolyzer projects worldwide, with installed capacity expected to grow significantly.

Jericho's Catalysts

According to Jericho Energy's April 2024 investor presentation, the spinout of Hydrogen Technologies Corp. aligns with a broader strategy to drive advancements in hydrogen technology. Currently, an area experiencing significant momentum due to global energy transition efforts, the investor presentation highlights key growth drivers, including Jericho’s patented hydrogen-based boiler technology and emerging partnerships with institutions and companies across the hydrogen sector. [OWNERSHIP_CHART-7025]

The decision to separate hydrogen assets positions HTC to capture opportunities within the rapidly expanding hydrogen ecosystem, benefiting from policy support and rising market demand for green energy solutions. As part of its strategy, Jericho intends to leverage its expertise in traditional energy systems while directing resources to support innovation in hydrogen applications.

The Biden administration is quietly engineering a series of expansions to Medicaid that may bolster protections for millions of low-income Americans and bring more people into the program.

Biden's efforts — which have been largely overshadowed by other economic and health initiatives — represent an abrupt reversal of the Trump administration's moves to scale back the safety-net program.

The changes could further boost Medicaid enrollment — which the pandemic has already pushed to a record 80.5 million. Some of the expansion is funded by the COVID-19 relief bill that passed in March, including coverage for new mothers.

Others who could also gain coverage under Biden are inmates and undocumented immigrants. At the same time, the administration is opening the door to new Medicaid-funded services such as food and housing that the government insurance plan hasn't traditionally offered.

"There is a paradigm change underway," said Jennifer Langer Jacobs, Medicaid director in New Jersey, one of a growing number of states trying to expand home-based Medicaid services to keep enrollees out of nursing homes and other institutions.

"We've had discussions at the federal level in the last 90 days that are completely different from where we've ever been before," Langer Jacobs said.

Taken together, the Medicaid moves represent some of the most substantive shifts in federal health policy undertaken by the new administration.

"They are taking very bold action," said Rutgers University political scientist Frank Thompson, an expert on Medicaid history, noting in particular the administration's swift reversal of Trump policies. "There really isn't a precedent."

The Biden administration seems unlikely to achieve what remains the holy grail for Medicaid advocates: getting 12 holdout states, including Texas and Florida, to expand Medicaid coverage to low-income working-age adults through the Affordable Care Act.

And while some of the recent expansions – including for new mothers -- were funded by close to $20 billion in new Medicaid funding in the COVID relief bill Biden signed in March, much of that new money will stop in a few years unless Congress appropriates additional money.

The White House strategy has risks. Medicaid, which swelled after enactment of the 2010 health law, has expanded further during the economic downturn caused by the pandemic, pushing enrollment to a record 80.5 million, including those served by the related Children's Health Insurance Program. That's up from 70 million before the COVID crisis began.

The programs now cost taxpayers more than $600 billion a year. And although the federal government will cover most of the cost of the Biden-backed expansions, surging Medicaid spending is a growing burden on state budgets.

The costs of expansion are a frequent target of conservative critics, including Trump officials like Seema Verma, the former administrator of the Centers for Medicare & Medicaid Services, who frequently argued for enrollment restrictions and derided Medicaid as low-quality coverage.

But even less partisan experts warn that Medicaid, which was created to provide medical care to low-income Americans, can't make up for all the inadequacies in government housing, food and education programs.

"Focusing on the social drivers of health ... is critically important in improving the health and well-being of Medicaid beneficiaries. But that doesn't mean that Medicaid can or should be responsible for paying for all of those services," said Matt Salo, head of the National Association of Medicaid Directors, noting that the program's financing "is simply not capable of sustaining those investments."

Restoring federal support

However, after four years of Trump administration efforts to scale back coverage, Biden and his appointees appear intent on not only restoring federal support for Medicaid, but also boosting the program's reach.

"I think what we learned during the repeal-and-replace debate is just how much people in this country care about the Medicaid program and how it's a lifeline to millions," Biden's new Medicare and Medicaid administrator, Chiquita Brooks-LaSure, told KHN, calling the program a "backbone to our country."

The Biden administration has already withdrawn permission the Trump administration had granted Arkansas and New Hampshire to place work requirements on some Medicaid enrollees.

In April, Biden blocked a multibillion-dollar Trump administration initiative to prop up Texas hospitals that care for uninsured patients, a policy that many critics said effectively discouraged Texas from expanding Medicaid coverage through the Affordable Care Act, often called Obamacare. Texas has the highest uninsured rate in the nation.

The moves have drawn criticism from Republicans, some of whom accuse the new administration of trampling states' rights to run their Medicaid programs as they choose.

"Biden is reasserting a larger federal role and not deferring to states," said Josh Archambault, a senior fellow at the conservative Foundation for Government Accountability.

But Biden's early initiatives have been widely hailed by patient advocates, public health experts and state officials in many blue states.

"It's a breath of fresh air," said Kim Bimestefer, head of Colorado's Department of Health Care Policy and Financing.

Chuck Ingoglia, head of the National Council for Mental Wellbeing, said: "To be in an environment where people are talking about expanding health care access has made an enormous difference."

Mounting evidence shows that expanded Medicaid coverage improves enrollees' health, as surveys and mortality data in recent years have identified greater health improvements in states that expanded Medicaid through the 2010 health law versus states that did not.

Broadening eligibility

In addition to removing Medicaid restrictions imposed by Trump administration officials, the Biden administration has backed a series of expansions to broaden eligibility and add services enrollees can receive.

Biden supported a provision in the COVID relief bill that gives states the option to extend Medicaid to new mothers for up to a year after they give birth. Many experts say such coverage could help reduce the U.S. maternal mortality rate, which is far higher than rates in other wealthy nations.

Several states, including Illinois and New Jersey, had sought permission from the Trump administration for such expanded coverage, but their requests languished.

The COVID relief bill — which passed without Republican support — also provides additional Medicaid money to states to set up mobile crisis services for people facing mental health or substance use emergencies, further broadening Medicaid's reach.

And states will get billions more to expand so-called home and community-based services such as help with cooking, bathing and other basic activities that can prevent Medicaid enrollees from having to be admitted to expensive nursing homes or other institutions.

Perhaps the most far-reaching Medicaid expansions being considered by the Biden administration would push the government health plan into covering services not traditionally considered health care, such as housing.

This reflects an emerging consensus among health policy experts that investments in some non-medical services can ultimately save Medicaid money by keeping patients out of the hospital.

In recent years, Medicaid officials in red and blue states — including Arizona, California, Illinois, Maryland and Washington — have begun exploring ways to provide rental assistance to select Medicaid enrollees to prevent medical complications linked to homelessness.

The Trump administration took steps to support similar efforts, clearing Medicare Advantage health plans to offer some enrollees non-medical benefits such as food, housing aid and assistance with utilities.

But state officials across the country said the new administration has signaled more support for both expanding current home-based services and adding new ones.

That has made a big difference, said Kate McEvoy, who directs Connecticut's Medicaid program. "There was a lot of discussion in the Trump administration," she said, "but not the capital to do it."

Other states are looking to the new administration to back efforts to expand Medicaid to inmates with mental health conditions and drug addiction so they can connect more easily to treatment once released.

Kentucky health secretary Eric Friedlander said he is hopeful federal officials will sign off on his state's initiative.

Still other states, such as California, say they are getting a more receptive audience in Washington for proposals to expand coverage to immigrants who are in the country without authorization, a step public health experts say can help improve community health and slow the spread of communicable diseases.

"Covering all Californians is critical to our mission," said Jacey Cooper, director of California's Medicaid program, known as Medi-Cal. "We really feel like the new administration is helping us ensure that everyone has access."

The Trump administration moved to restrict even authorized immigrants' access to the health care safety net, including the "public charge" rule that allowed immigration authorities to deny green cards to applicants if they used public programs such as Medicaid. In March, Biden abandoned that rule.

Despite the racial reckoning going on in America right now, and despite the fact that attitudes towards race, inclusion and representation are different now than they were 30 years ago, new research from UC Berkeley shows that a large majority of American metro areas are more segregated now than they were in 1990. The new report from Berkeley’s Institute covers a number of topic areas, but among the key findings were from the national segregation report component of the project, which found Los Angeles to be the sixth-most segregated metro area with more than 200,000 people.

Today on AirTalk, we’ll talk with the lead researcher on the new report and a local historian to talk about how we see the findings of the report play out in Southern California.

The Los Angeles City Council votes Thursday on a proposal to ban sleeping or camping in certain parts of the city, including near schools, parks, libraries, and other “sensitive” facilities like daycares. It would also ban tents and encampments from blocking sidewalks if wheelchair users cannot access them. The motion is a departure from the city’s previous approach to the homelessness crisis.

Council members voted 12 to 3 on Tuesday to pull the draft ordinance out of Homelessness and Poverty Committee, where it had been stuck since November, and directed City Attorney Mike Feuer’s office to draft the new rules. Today on AirTalk, we’re speaking with Los Angeles Times reporter Ben Oreskes about the proposed rules, what Thursday’s vote means, and what we know about possible legal ramifications of the proposed changes.

California on Thursday scheduled a Sept. 14 recall election that could drive Democratic Gov. Gavin Newsom from office, the result of a political uprising largely driven by angst over state coronavirus orders that shuttered schools and businesses and upended life for millions of Californians.

The election in the nation’s most populous state will be a marquee contest with national implications, watched closely as a barometer of the public mood heading toward the 2022 elections, when a closely divided Congress again will be in play.

We’ll get the latest.

Copy of the book “Beyond Baseball’s Color Barrier: The Story of African Americans in Major League Baseball, Past, Present, and Future” (Rowman & Littlefield, May 2021)

Most of us are familiar with the story of Jackie Robinson, the first Black player to play baseball in the Major Leagues, and while Jackie’s story is arguably the biggest chapter in the story of how baseball was integrated, there’s plenty more to the story that happened both before and after Jackie broke into the Majors. Author, sports historian and Santa Barbara City College Director of Athletics Rocco Constantino dives into this rich history in his new book “Beyond Baseball’s Color Barrier: The Story of African Americans in Major League Baseball, Past, Present, and Future” where he explores the contributions of major figures like Hank Aaron, Willie Mays and Satchel Paige as well as the lesser known ones of players like Vida Blue, Mudcat Grant and Dwight Gooden.

Today on AirTalk, Constantino joins Larry Mantle to explore the history of Black players in baseball, their fight for recognition and integration into the Major Leagues and the issues of race that persisted well beyond Jackie Robinson breaking baseball’s color barrier.

Restoration of the imperiled sagebrush biome will require tools that assist resource managers in determining which restoration practices are most effective, and when and where restoration efforts will lead to the most ecosystem recovery. New research from USGS and Colorado State University provides biome-wide insights and spatially explicit tools that can inform restoration practices. 

The USGS is pleased to announce the release of new US Topo maps for Puerto Rico and the U.S. Virgin Islands. These updated topographic maps offer valuable, current geographic information for residents, visitors, and professionals, providing essential resources for communities in these areas.

The USGS is working with federal land management agencies to develop a series of structured science syntheses (SSS) to support National Environmental Policy Act (NEPA) analyses. This new synthesis is the third publication in the SSS series and provides science to support NEPA analyses for agency decisions regarding oil and gas leasing and permitting.
