Summary: The high-pressure behavior of natural stellerite has been studied and compared with Na-rich stilbite using single-crystal X-ray diffraction. Both minerals undergo pressure-induced hydration, but the presence of sodium in stilbite affects its behavior. The changes in structure and hydration behavior are less significant in Na-bearing stilbite compared to stellerite.

Summary: The study found that the water density around antifreeze proteins is related to the hydrophobicity of the proteins. There are differences in water density around the ice-binding and non-ice-binding surfaces of antifreeze proteins with different activities, which may contribute to the differences in their ability to inhibit ice growth.

Summary: In this study, magnesium slag was modified by quenching hydration to improve its desulfurization activity. Crystal structure and morphology characteristics were obtained by XRD and TEM, and desulfurization experiments were carried out by TGA to understand the relationship between crystal structure and performance. The results showed that naturally cooled magnesium slag mainly consisted of gamma-C2S and beta-C2S, with beta-C2S exhibiting higher hydration activity than gamma-C2S.

Summary: Rapid phase elucidation is crucial in the development of new materials. However, routine X-ray diffraction analysis is often limited by the small size and quantity of crystalline phases. In this study, we demonstrate the use of SerialRED for high-throughput phase identification of complex polycrystalline zeolite products. By automating the analysis of hundreds of crystals, SerialRED enables the identification of zeolite phases that are undetectable using X-ray diffraction, providing new opportunities for rapid development of polycrystalline materials.

Summary: High-pressure synchrotron X-ray diffraction was used to compress a single crystal of mascagnite in a diamond anvil cell, and the results showed that the sample maintained its crystal structure at high pressures. The incompressibility of sulphate polyhedra and the increase in density were attributed to changes in weaker hydrogen bonds.

Summary: Porous mineral interaction with liquids, especially water, is crucial in many technological and geochemical processes. The behavior of apophyllite, a mixed layered and framework microporous silicate, was studied under high pressure and high temperature conditions using in situ Raman spectroscopy. Results showed that the composition of the pressure medium and temperature influenced its behavior. Regardless of the compressing medium, the lattice vibrational modes of apophyllite showed consistent pressure shifts at high temperature. The behavior of apophyllite was similar in both penetrating and nonpenetrating media, indicating no pressure-induced overhydration. These findings emphasize the importance of structural factors such as limited water mobility and strong contacts between silicate layers in determining the tolerance towards the penetration of additional molecules. Elevated temperature did not affect the mobility of interlayer water molecules for pressure-induced intercalation in apophyllite.

Summary: Three samples of fluorapophyllite-(K) with different cation composition were studied. The deficiency of large cations K+ and (NH4)(+) in the A site in Nidym and Akhaltsykhe samples is compensated by the presence of medium-sized Na+ cations. The occurrence of ammonium ions is found in Nidym and Talnakh samples and their concentrations are estimated.

Summary: The partitioning of nitrogen between different hosts was studied using partially devolatilized natural quartz-muscovite-chlorite schist (mica schist) containing NH4+-rich muscovite, under conditions corresponding to hot subduction. The results showed that the contents of NH4+ in the analyzed metapelite decrease with increasing pressure and temperature, suggesting the efficiency of ammonium outgassing from subducting metasediments. The nitrogen partitioning under hot subduction conditions is controlled by devolatilization of metasediments, phase transitions in Nbearing micas, and changes in fluid composition.

Summary: The unique minerals of the Au-Pd-Hg system in gold grains from heavy concentrates of the Itchayvayam placers and watercourses draining and ore samples of the Barany outcrop at the Itchayvayam mafic-ultramafic complex (Kamchatka, Russia) were studied. The composition and structure of the minerals were analyzed using XRD and EBSD. The results revealed the presence of Pd,Hg-rich low-fineness gold, Pd,Hg-poor high-fineness gold, and other compositions in the Au-Pd-Hg system. The genesis of Pd,Hg-rich gold is still not fully understood, but it may be related to meteoric waters or low-temperature hydrotherms rich in Pd and Hg.

Summary: MOF materials with adjustable pore structure and polymetallic sites have been explored as electrocatalysts for OER. Bimetallic materials show higher electrocatalytic activity than monometallic materials, while carbon-coated and doped MOF catalysts exhibit stable and good OER activity. The synergistic interaction between polymetallic active sites effectively improves the intrinsic activity of MOF on OER.

Summary: This study investigates the evolution and autoreduction behavior of Cu species in CuCl/NaY adsorbent during vacuum thermal activation. It is found that Cu species migrate from supercages to the nearby plane of the six-membered ring connecting the supercage and sod cage during vacuum activation. At 150 degrees C, vacuum autoreduction occurs, resulting in the formation of Cu+Cl- species. The results provide reference for the preparation of pi-complex adsorbents.

Summary: Hierarchical porous system with two types of mesopores provides a solution to the diffusion limitation in conventional zeolites. Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations. Catalytic activity analysis showed that Co-oxide/ZSM-5 with inter-crystalline mesopores exhibited higher activity in methane partial oxidation reaction compared to Co-oxide/ZSM-5 with intra-crystalline mesopores.

The strong adsorption of benzene on Co is found to lower the activation energy for methane dissociation and promote the formation of toluene precursor.
