A new method based on time-resolved X-ray diffraction is proposed in order to measure the elastic strain and stress during ultrasonic fatigue loading experiments. Pure Cu was chosen as an example material for the experiments using a 20 kHz ultrasonic fatigue machine mounted on the six-circle diffractometer available at the DiffAbs beamline on the SOLEIL synchrotron facility in France. A two-dimensional hybrid pixel X-ray detector (XPAD3.2) was triggered by the strain gage signal in a synchronous data acquisition scheme (pump–probe-like). The method enables studying loading cycles with a period of 50 µs, achieving a temporal resolution of 1 µs. This allows a precise reconstruction of the diffraction patterns during the loading cycles. From the diffraction patterns, the position of the peaks, their shifts and their respective broadening can be deduced. The diffraction peak shift allows the elastic lattice strain to be estimated with a resolution of ∼10−5. Stress is calculated by the self-consistent scale-transition model through which the elastic response of the material is estimated. The amplitudes of the cyclic stresses range from 40 to 120 MPa and vary linearly with respect to the displacement applied by the ultrasonic machine. Moreover, the experimental results highlight an increase of the diffraction peak broadening with the number of applied cycles.

Rietveld/MEM analysis applied to synchrotron powder X-ray diffraction data of dehydrated CHA zeolites with catalytically active Cu2+ reveals Cu2+ in both the six- and eight-membered rings in the CHA framework, providing the first complete structural model that accounts for all Cu2+. Density functional theory calculations are used to corroborate the experimental structure and to discuss the Cu2+ coordination in terms of the Al distribution in the framework.

A review of recent and ongoing development and results within the field of biological solution small-angle X-ray scattering (BioSAXS), with a focus on the increasing complexity of biological samples, data collection and data evaluation strategies.

A novel sample cell with control of temperature and relative humidity permitted collection of data of excellent quality, enabling unrestrained refinement of all atomic parameters. One of the K atoms in the structure is disordered; very strong anisotropy in three of the four water O atoms indicates partial static disorder, which does not involve the bonded H atoms.

The title compound, C24H18FNO3, crystallizes in the monoclinic centrosymmetric space group P21/n and its mol­ecular conformation is stabilized via C—H⋯O intra­molecular inter­actions. The supra­molecular network mainly comprises C—H⋯O, C—H⋯F and C—H⋯π inter­actions, which contribute towards the formation of the crystal structure. The different inter­molecular inter­actions have been further analysed via Hirshfeld surface analysis and fingerprint plots.

The preferred orientation growth characteristics and surface roughness of polycrystalline bis­muth (Bi) thin films fabricated on glass substrates using the molecular beam epitaxy method were investigated at temperatures ranging from 18 to 150°C. The crystallization and morphology were analyzed in detail and the polycrystalline metal film structure-zone model (SZM) was modified to fit the polycrystalline Bi thin film. The boundary temperature between Zone T and Zone II in the SZM shifted to higher temperatures with the increase in film thickness or the decrease of growth rate. Furthermore, the effect of the thickness and surface roughness on the transport properties was investigated, especially for Bi thin films in Zone II. A two-transport channels model was adopted to reveal the influence of the film thickness on the competition between the metallic surface states and the semiconducting bulk states, which is consistent with the results of Bi single-crystal films. Therefore, the polycrystalline Bi thin films are expected to replace the single-crystal films in the application of spintronic devices.

A scanning soft X-ray spectromicroscope was recently developed based mainly on the photon-in/photon-out measurement scheme for the investigation of local electronic structures on the surfaces and interfaces of advanced materials under conditions ranging from low vacuum to helium atmosphere. The apparatus was installed at the soft X-ray beamline (BL17SU) at SPring-8. The characteristic features of the apparatus are described in detail. The feasibility of this spectromicroscope was demonstrated using soft X-ray undulator radiation. Here, based on these results, element-specific two-dimensional mapping and micro-XAFS (X-ray absorption fine structure) measurements are reported, as well as the observation of magnetic domain structures from using a reference sample of permalloy micro-dot patterns fabricated on a silicon substrate, with modest spatial resolution (e.g. ∼500 nm). Then, the X-ray radiation dose for Nafion® near the fluorine K-edge is discussed as a typical example of material that is not radiation hardened against a focused X-ray beam, for near future experiments.

Synchrotron X-ray diffraction (XRD) measured on the XMaS beamline at the ESRF was used to characterize the alloy composition and crystalline surface corrosion of three copper alloy Tudor artefacts recovered from the undersea wreck of King Henry VIII's warship the Mary Rose. The XRD method adopted has a dynamic range ∼1:105 and allows reflections <0.002% of the height of major reflections in the pattern to be discerned above the background without smoothing. Laboratory XRD, scanning electron microscopy–energy dispersive spectroscopy, synchrotron X-ray fluorescence and X-ray excited optical luminescence–X-ray near-edge absorption structure were used as supporting techniques, and the combination revealed structural and compositional features of importance to both archaeology and conservation. The artefacts were brass links believed to be fragments of chainmail and were excavated from the seabed during 1981 and 1982. Their condition reflects very different treatment just after recovery, viz. complete cleaning and conservation, chemical corrosion inhibition and chloride removal only, and distilled water soaking only (to remove the chlorides). The brass composition has been determined for all three at least in the top 7 µm or so as Cu(73%)Zn(27%) from the lattice constant. Measurement of the peak widths showed significant differences in the crystallite size and microstrain between the three samples. All of the links are found to be almost chloride-free with the main corrosion products being spertiniite, sphalerite, zincite, covellite and chalcocite. The balance of corrosion products between the links reflects the conservation treatment applied to one and points to different corrosion environments for the other two.

The crystal structure of the organic pigment 2-monomethyl-quinacridone (Pigment Red 192, C21H14N2O2) was solved from X-ray powder diffraction data. The resulting average structure is described in space group Poverline 1, Z = 1 with the molecule on the inversion centre. The molecules are arranged in chains. The molecules, which have no inversion symmetry, show orientational head-to-tail disorder. In the average structure, the methyl group is disordered and found on both ends of the molecule with an occupancy of 0.5 each. The disorder and the local structure were investigated using various ordered structural models. All models were analysed by three approaches: Rietveld refinement, structure refinement to the pair distribution function (PDF) and lattice-energy minimization. All refinements converged well. The Rietveld refinement provided the average structure and gave no indication of a long-range ordering. The refinement to the PDF turned out to be very sensitive to small structural details, giving insight into the local structure. The lattice-energy minimizations revealed a significantly preferred local ordering of neighbouring molecules along the [0ar 11] direction. In conclusion, all methods indicate a statistical orientational disorder with a preferred parallel orientation of molecules in one direction. Additionally, electron diffraction revealed twinning and faint diffuse scattering.

The crystal structure of the nanocrystalline pigment mono­methyl-quinacridone was solved from X-ray powder data. The orientational disorder was investigated using Rietveld refinements, structure refinement to the pair-distribution function, and lattice-energy minimizations of various ordered structural models.

Structural investigations of amorphous and nanocrystalline phases forming in solution are historically challenging. Few methods are capable of in situ atomic structural analysis and rigorous control of the system. A mixed-flow reactor (MFR) is used for total X-ray scattering experiments to examine the short- and long-range structure of phases in situ with pair distribution function (PDF) analysis. The adaptable experimental setup enables data collection for a range of different system chemistries, initial supersaturations and residence times. The age of the sample during analysis is controlled by adjusting the flow rate. Faster rates allow for younger samples to be examined, but if flow is too fast not enough data are acquired to average out excess signal noise. Slower flow rates form older samples, but at very slow speeds particles settle and block flow, clogging the system. Proper background collection and subtraction is critical for data optimization. Overall, this MFR method is an ideal scheme for analyzing the in situ structures of phases that form during crystal growth in solution. As a proof of concept, high-resolution total X-ray scattering data of amorphous and crystalline calcium phosphates and amorphous calcium carbonate were collected for PDF analysis.

A new type of X-ray LLL interferometer, a `hard' interferometer, which has both a base and a `ceiling', is tested for experimental investigations. The tested interferometer has no preliminary uncontrollable moiré and can be used for object and deformation investigations.

A Washington, D.C., think tank issued a report that says California Virtual Acadmies, a major online school network, has had more dropouts than graduates in most years.; Credit: Jeff J Mitchell/Getty Images

A report released Thursday by a labor group-affiliated Washington think tank is questioning the education provided by an online public school program that says it is in a union fight.

The report by In the Public Interest, a group funded by unions, says the thousands of students enrolled in the California Virtual Academies online public school known as CAVA are receiving a  substandard education by most measures.

"So in every year since CAVA began graduating students, with the exception of 2013, it has produced more dropouts than graduates,” said Shahrzad Habibi, who authored the report.

She said state test score data show that 71 percent of California public schools performed better than the virtual academies.

The report calls on California officials to investigate the online schools’ administration and finances.

California Virtual Academies enrolls about 14,000 kindergarten to 12th grade students through 11 sites, including those in Los Angeles, San Diego, and Fresno. It is run by a national for-profit company called K12 Inc.

In a written statement, California Virtual Academies did not dispute the reported low student performance numbers, but denied other allegations in the study, which it called “inaccurate and deeply flawed.”

“The report relies primarily on misinformation from the California Teachers Association — the union currently engaged in a coordinated and well-funded distortion campaign to unionize the eleven independent California Virtual Academies charter schools.”

In the Public Interest, which supports the work of labor unions, partnered with the American Federation of Teachers last year on a website to track for-profit charter school companies.

Commercial-stage biotechnology company Portola Pharmaceuticals Inc. (PTLA:NASDAQ), which focuses on blood-related disorders, and global biopharmaceuticals firm Alexion Pharmaceuticals Inc. (ALXN:NASDAQ) announced that they have entered into a definitive merger agreement for Portola to be acquired by Alexion.

The acquisition is said to provide a key addition to Alexion's diversified commercial portfolio. The report indicated that the merger agreement has already been unanimously approved each of the company's boards of directors.

The report explained that "Portola's commercialized medicine, Andexxa^® [coagulation factor Xa (recombinant), inactivated-zhzo], marketed as Ondexxya^® in Europe, is the first and only approved Factor Xa inhibitor reversal agent, and has demonstrated transformative clinical value by rapidly reversing the anticoagulant effects of Factor Xa inhibitors rivaroxaban and apixaban in severe and uncontrolled bleeding."

Portola's President and CEO Scott Garland commented, "In developing and launching Andexxa, Portola has established a strong foundation for changing the standard of care for patients receiving Factor Xa inhibitors that experience a major, life-threatening bleed. Andexxa rapidly reverses the pharmacologic effect of rivaroxaban and apixaban within two minutes, reducing anti-Factor Xa activity by 92 percent...Given their enhanced resources, global footprint and proven commercial expertise, we look forward to working with Alexion to maximize the value of Andexxa. With their commitment to commercial excellence, together, we will be able to drive stronger utilization of Andexxa, increase penetration and accelerate adoption in the critical care setting."

Ludwig Hantson, Ph.D., CEO of Alexion, remarked, "The acquisition of Portola represents an important next step in our strategy to diversify beyond C5. Andexxa is a strategic fit with our existing portfolio of transformative medicines and is well-aligned with our demonstrated expertise in hematology, neurology and critical care...We believe Andexxa has the potential to become the global standard of care for patients who experience life-threatening bleeds while taking Factor Xa inhibitors apixaban and rivaroxaban. By leveraging Alexion's strong operational and sales infrastructure and deep relationships in hospital channels, we are well positioned to expand the number of patients helped by Andexxa, while also driving value for shareholders."

The firms advised that "under the terms of the merger agreement, a subsidiary of Alexion will commence a tender offer to acquire all of the outstanding shares of Portola's common stock at a price of $18 per share in cash." Alexion plans to fund the purchase with existing cash on hand and the transaction is expected to close in Q3/20. The purchase is subject to approval by a majority interest of Portola's common stockholders tendering their shares along with ordinary closing conditions and regulatory approvals. The company noted that "following successful completion of the tender offer, Alexion will acquire all remaining shares not tendered in the offer at the same price of $18 per share through a merger."

Alexion is a global biopharmaceutical company based in Boston, Mass., with offices in 50 countries worldwide. The company states that it has been "the global leader in complement biology and inhibition for more than 20 years and that it has developed and commercializes two approved complement inhibitors to treat patients with paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome, as well as the first and only approved complement inhibitor to treat anti-acetylcholine receptor antibody-positive generalized myasthenia gravis and neuromyelitis optica spectrum disorder."

Portola is headquartered in South San Francisco, Calif., and is a commercial-stage biopharmaceutical company focused on treating patients with serious blood-related disorders. Specifically, the company is engaged in developing and commercializing novel therapeutics in order to advance the fields of thrombosis and other hematologic conditions. The firm listed that its first two commercialized products are Andexxa^® and Bevyxxa^® (betrixaban), and that it is also advancing and developing cerdulatinib, a SYK/JAK inhibitor for use in treatment of hematologic cancers.

Portola Pharmaceuticals started off the day with a market capitalization of around $609.0 million with approximately 78.5 million shares outstanding and a short interest of about 23.0%. PTLA shares opened 130% higher today at $17.85 (+$10.09, +130.03%) over yesterday's $7.85 closing price. The stock has traded today between $17.71 and $17.91 per share and is currently trading at $17.83 (+$10.07, +129.77%).
