Summary: In this study, nonrelativistic spin-momentum coupling is predicted in two-dimensional materials. Twist operations in antiferromagnetic bilayers can induce spin splitting comparable to spin-orbit coupling, and generate a transverse spin current with a high charge-spin conversion ratio. These findings demonstrate the potential for achieving electrically controlled magnetism in materials without spin-orbit coupling.

Summary: This study investigated the photo reactivity of Ferric oxalate (Fe(III)-Ox) complex in atmospheric particles using Raman spectroscopy. It was found that the concentration of photoproduct Fe(II)-Ox was higher at the surface and inside of the droplets compared to bulk solution. Despite hindering the Fenton intermediate reaction, FeCO3, the photolysis rate of Fe(III)-Ox in droplets was significantly faster than in bulk solution. The mechanism and kinetics of Fe(III)-Ox photolysis varied between the aqueous/gas interface, inside of droplets, and bulk solution, leading to an underestimation of oxide species production from atmospheric Fe(III)-Ox droplets.

Summary: Increasing the Pt surface concentration can decrease the ignition temperature of CO oxidation and enhance the stability of the Pt/CeO2 catalyst. The improved reaction rate at higher Pt surface concentrations is attributed to the formation of larger oxidized Pt clusters and the aggregation of highly dispersed Pt species. The influence of the Pt surface noble metal concentration on the reaction rate is temporarily diminished when Pt particle formation is forced.

Summary: A new approach using mixtures of triphenylphosphine dichloride or oxalyl chloride and hydrogen peroxide in organic solvents was developed for the rapid dissolution of elemental noble metals (NMs). Almost complete dissolution of gold, palladium, and copper was observed within minutes at room temperature. This method has potential applications in the hydrometallurgical leaching and purification of NMs from ores, spent catalysts, and electronic and nano-wastes.

Summary: Vibrational spectroscopy coupled with isotopic labeling is used to study the dynamics of molecular processes, utilizing a newfound approach in surface-enhanced Raman scattering (SERS). The study focuses on noble metal-anchored thiol monolayers and demonstrates the distinctive difference in Raman shift value between two isotopologues on silver nanoparticles. The SERS intensity ratio of these isotopologues allows for quantitative monitoring of the entropy-driven exchange of molecules between the surface and solution, revealing a reversible and rapid activation behavior after a temperature increase.

Summary: This study compared three methods for quantitatively distinguishing the location of noble metal particles in mesopores from those on the external support surface, and evaluated the effectiveness of using phosphine/NM ratios and pore filling techniques to determine the distribution of NMs. The results showed that the method of filling pores with TEOS proved promising for accurately locating NMs on the external surface, providing insights for future research on the characterization and quantification of NM distribution in mesoporous materials.

Summary: The NgF(2) center dot MOF4 and XeF2 center dot 2MOF(4) complexes were synthesized using anhydrous HF solvent and melts, and their structures were characterized by single-crystal X-ray diffraction. The bond lengths in these complexes were found to follow fluoride-ion affinity trends, and quantum-chemical calculations revealed that the M---F-b bonds are predominantly electrostatic, sigma-hole type bonds.

Summary: The accumulation of naringenin in rice is regulated by genes such as Os07g32020, which encodes a glycosyltransferase that promotes the conversion of naringenin. Modification of the Os07g32020 gene could be used to increase the production of naringenin and sakuranetin rice flavonoids in a more targeted manner. This opens up new opportunities for selective breeding of this important rice metabolic trait.
