Abstract The water-gas shift reaction (WGSR) is an intermediate reaction in hydrocarbon reforming processes, considered one of the most important reactions for hydrogen production. Here, water and carbon monoxide molecules react to generate hydrogen and carbon dioxide. From the thermodynamics aspect, pressure does not…
Abstract Discovering new functional genes, designing perfect crystal structures, and developing high‐performance materials are the goals being pursued by scientists. Herein, the first antimony pyrophosphate, K 2 Sb(P 2 O 7 )F, possessing an optimal layered structure, is reported, where the perfect structural arrangeme…
The article has been presented at the 30th Annual Meeting of the Japanese Glaucoma Society on 7 September 2019.

Microcrystal electron diffraction (MicroED) is becoming a powerful tool in determining the crystal structures of biological macromolecules and small organic compounds. An advantage of electron diffraction is that its resolution is just weakly influenced by the performance of the objective lens. Therefore, even on a lo…
Abstract Thermal demagnetization furnaces are widely used paleomagnetic facilities for progressive removal of naturally acquired magnetic remanence or the imparting of well controlled laboratory magnetization. An ideal thermal demagnetizer should maintain “zero” magnetic field in the sample chamber during thermal trea…
Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species.
Nanoparticle (NP) delivery to solid tumors has recently been questioned. To better understand the magnitude of NP tumor delivery, we reanalyzed published murine NP tumor pharmacokinetic (PK) data used in the Wilhelm et al. study. Studies included in their analysis reporting matched tumor and blood concentration versus…

The photoelectric absorption mass attenuation coefficients (m.a.c.) of ɤ- rays in Cu are measured using a two 3"x3" NaI(Tl) detector coincidence spectrometer at 511, 1173 and 1332keV energy gates using Na-22 and Co-60 point sources. The m.a.c. (in cm²/g) measured by coincidence method were lower than those obtained fr…
To engineer tunable thin film materials, accurate measurement of their mechanical properties is crucial. However, characterizing the elastic modulus with current methods is particularly challenging for sub-micrometer thick films and hygroscopic materials because they are highly sensitive to environmental conditions an…
Understanding pressure-induced structural changes in amorphous dioxides (a-AO2) is of great importance in many fields of science. Here we report new experimental results of high pressure polyamorphism in amorphous TiO2 (a-TiO2) with the Ti-O coordination number (CN) close to 9. Our experimental data show that CN incre…
Scientific experiments that require the need to use extreme sample environments are ideally suited for neutron experiments due to the high penetration and non-destructive nature of biomass. The Bio-SANS instrument at Oak Ridge National Laboratory has developed a pressure cell that allows to heat the cell up to 300 C a…
Understanding the function of disordered proteins or soft-matter complexes requires understanding of their conformational ensembles. However, experimental data alone is often insufficient for defining all degrees of freedom of such systems, whereas simulations may be biased by poor sampling or force field limitations.…
Actins are among the most abundant proteins in cells. They form filaments, which are involved in essential processes in the cell, including cell division, transport, motility, and structural functions. Polymerization involves a transition of monomeric (G-form) actin to the filamentous F-form. Conformational changes up…
Many framework materials such as metal-organic frameworks (MOF) or porous coordination polymers (PCPs) are synthesized as polycrystalline powders, which are too small for structure determination by single crystal X-ray diffraction (SCXRD). Here, we show that a three-dimensional (3D) electron diffraction method, namely…
A perovskite LaCoO3 was prepared by combustion and citrate-gel methodsin order to test its possible application as a chemical sensor. The crystal evolution, structure, composition, texture, morphology, and particle size were analyzed by X-ray diffraction, BET and scanning electron microscopies. The effects of doped Sr…
A special advantage of protein crystallography is quick determination of target proteins for biological science and high-throughput structure determination of a large number of protein-compound complexes for pharmaceutical science. To achieve the quick structure determination, utilization of well-experienced protein c…
