Through a combination of magnetic susceptibility, specific heat, and neutron powder diffraction measurements we have revealed a sequence of four magnetic phase transitions in the columnar quadruple perovskite Er2CuMnMn4O12. A key feature of the quadruple perovskite structural framework is the complex interplay of multiple magnetic sublattices via frustrated exchange topologies and competing magnetic anisotropies. It is shown that in Er2CuMnMn4O12, this phenomenology gives rise to multiple spin-reorientation transitions driven by the competition of easy-axis single ion anisotropy and the Dzyaloshinskii–Moriya interaction; both within the manganese B-site sublattice. At low temperature, one Er sublattice orders due to a finite f-d exchange field aligned parallel to its Ising axis, while the other Er sublattice remains non-magnetic until a final, symmetry-breaking phase transition into the ground state. This non-trivial low-temperature interplay of transition metal and rare-earth sublattices, as well as an observed k = (0, 0, ½) periodicity in both manganese spin canting and Er ordering, raises future challenges to develop a complete understanding of the R2CuMnMn4O12 family.

Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) is the enzyme responsible for the first step of carbon dioxide (CO2) fixation in plants, which proceeds via the carboxylation of ribulose 1,5-biphosphate. Because of the enormous importance of this reaction in agriculture and the environment, there is considerable interest in the mechanism of fixation of CO2 by RuBisCO. Here, a serial synchrotron crystallography structure of spinach RuBisCO is reported at 2.3 Å resolution. This structure is consistent with earlier single-crystal X-ray structures of this enzyme and the results are a good starting point for a further push towards time-resolved serial synchrotron crystallography in order to better understand the mechanism of the reaction.

Combined 100 ms resolved grazing-incidence small/wide-angle X-ray scattering and optical interferometry reveal that the additive diiodooctane can significantly double the solvent evaporation rate, thereby effectively suppressing the rapid spinodal decomposition process in the early stage of spin-coasting, favouring slow phase segregation kinetics with nucleation and growth.

The crystal structures of three mixed-valence copper cyanide alkanolamine polymers are presented, together with thermogravimetric analysis (TGA) and electron spin resonance (ESR) data. In all three structures, a CuII moiety on a crystallographic center of symmetry is coordinated by two alkanolamines and links two CuICN chains via cyanide bridging groups to form diperiodic sheets. The sheets are linked together by cuprophilic CuI–CuI inter­actions to form a three-dimensional network. In poly[bis­(μ-3-amino­propano­lato)tetra-μ-cyan­ido-dicopper(I)dicopper(II)], [Cu4(CN)4(C3H8NO)2]n, 1, propano­lamine bases have lost their hydroxyl H atoms and coordinate as chelates to two CuII atoms to form a dimeric CuII moiety bridged by the O atoms of the bases with CuII atoms in square-planar coordination. The ESR spectrum is very broad, indicating exchange between the two CuII centers. In poly[bis­(2-amino­pro­pan­ol)tetra-μ-cyanido-dicopper(I)copper(II)], [Cu3(CN)4(C3H9NO)2]n, 2, and poly[bis­(2-amino­ethanol)tetra-μ-cyanido-dicopper(I)copper(II)], [Cu3(CN)4(CH7NO)2]n, 3, a single CuII atom links the CuICN chains together via CN bridges. The chelating alkanolamines are not ionized, and the OH groups form rather long bonds in the axial positions of the octa­hedrally coordinated CuII atoms. The coordination geometries of CuII in 2 and 3 are almost identical, except that the Cu—O distances are longer in 2 than in 3, which may explain their somewhat different ESR spectra. Thermal decom­position in 2 and 3, but not in 1, begins with the loss of HCN(g), and this can be correlated with the presence of OH protons on the ligands in 2 and 3, which are not present in 1.

X-ray reflectometry (XRR) is a powerful tool for probing the structural characteristics of nanoscale films and layered structures, which is an important field of nanotechnology and is often used in semiconductor and optics manufacturing. This study introduces a novel approach for conducting quantitative high-resolution millisecond monochromatic XRR measurements. This is an order of magnitude faster than in previously published work. Quick XRR (qXRR) enables real time and in situ monitoring of nanoscale processes such as thin film formation during spin coating. A record qXRR acquisition time of 1.4 ms is demonstrated for a static gold thin film on a silicon sample. As a second example of this novel approach, dynamic in situ measurements are performed during PMMA spin coating onto silicon wafers and fast fitting of XRR curves using machine learning is demonstrated. This investigation primarily focuses on the evolution of film structure and surface morphology, resolving for the first time with qXRR the initial film thinning via mass transport and also shedding light on later thinning via solvent evaporation. This innovative millisecond qXRR technique is of significance for in situ studies of thin film deposition. It addresses the challenge of following intrinsically fast processes, such as thin film growth of high deposition rate or spin coating. Beyond thin film growth processes, millisecond XRR has implications for resolving fast structural changes such as photostriction or diffusion processes.

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.

Ownership and Share Structure

Around 35% of Jericho's shares are held by management, insiders, and insider institutional investors, the company said. They include CEO Brian Williamson, who owns 1.19% or about 3.1 million shares; founder Allen Wilson, who owns 0.76% or about 1.97 million shares; and board member Nicholas Baxter, who owns 0.44%, or about 1.14 million shares, according to Refinitiv' latest research.

Around 10% of shares are held by non-insider institutions, and approximately 55% are in retail, the company said.

On March 6, 2023, JEV completed an insider-led private placement financing, above the current share price, for gross proceeds of CA$2.23 million.

JEV's market cap is CA$25.19 million, and it trades in a 52-week range of CA$0.07 and CA$0.18. It has 259.75 million shares outstanding, approx.. 189.99 million floating.

On the eve of Killing Eve's series finale (airing this weekend), Deadline reports that "producer Sid Gentle Films is in early stage development on [a] spin-off, though it hasn’t got a greenlight yet." The spin-off (for BBC America and AMC Networks) would focus on Fiona Shaw's character, Carolyn Martens... but not as the cool, commanding spymaster we met in the show's first season. Instead, the potential spin-off would focus on her early days with MI6. From what we know of her history on the show, that could be incredibly compelling! Presumably such a series would focus on her time on Russia Desk and in Moscow during the waning days of the Cold War, when she recruited a crucial asset. I'm not so interested in this potential series because of its Killing Eve connection (though I do love that show's wit and tone and performances, and it would be nice to see them continue), but because of its setting. We don't see many Cold War era series, and when they do come along, I'll always be watching! It would be particularly cool to see one set in the late 80s with that focus. The Americans of course reveled in its 80s setting, but that was focused on Soviet agents undercover in America. A show about a British agent operating in Moscow at that time would be very different!

The locker sat empty in the happy clubhouse, its contents packed away and its occupant gone. Danny Espinosa has been a key contributor to the Nationals since his first promotion from the minor leagues late in the 2010 season. He has played 390 games for Washington, most of them at second base. But on Tuesday he was absent, a glaring void next to his normal spot alongside teammate Ian Desmond’s stall. Around the room loud music blasted from the stereo system after a thrilling 3-2 comeback win over the New York Mets on Tuesday night. Espinosa wasn’t there to enjoy it.

I'm a 40F who upon hearing the election results this week, felt a surge a gratitude about being a spinster. I figure there has to be articles, books, or some type of literature made by fellow spinsters throughout history about their experiences.

I'm a 40F who upon hearing the election results this week, felt a surge a gratitude about having no kids or a male partner. I of course have been on this path for years, mostly due to my total disinterest in dating and or sex. (I didn't realize I was a OG member of the 4B Movement.)
The choice to forego the things that many women consider their purpose in life does make you feel like the weird one.
I figure there has to be articles, books, or some type of literature made by fellow spinsters throughout history about their experiences. It find it a 95 percent positive experience, but I'd also be curious if these ladies have also written about the drawbacks (money troubles, not being anyone's person) as well.
I'd be curious how the stigma played out then as it does now, I figure it was worse then due to not being able to get good jobs, but I know in some places, these women served as elderly caretakers. I look forward to learning more.
