The title compound, [Na(C(10)H(9.5)N(2)O(2)S(2))(2)(H(2)O)], is a mol-ecular sodium complex with N'-(1,3-dithio-lan-2-yl)-2-hy-droxy-benzohydrazide ligands with the negative charge spread evenly over both, and a water mol-ecule. The Na(I) ion coordination is distorted trigonal-bipyramidal, formed by two N and three O atoms, with the Na(I) ion lying on a twofold rotation axis. Intra-molecular N-H⋯O hydrogen bonds occur. Mol-ecules pack as discrete units and the crystal packing is stabilized by strong O-H⋯O hydrogen bonds, which give rise to chains along [010]; the chains are inter-linked by strong O-H⋯O hydrogen bonds.

CYP105A1 exhibits monooxygenase activity to a wide variety of structurally different substrates with regio- and stereospecificity, making its application range broad. Our previous studies have shown that CYP105A1 wild type and its variants metabolize 12 types of nonsteroidal anti-inflammatory drugs (NSAIDs). In particular, the R84A variant exhibited a high activity against many NSAIDs.

The synthesis and characterization of benzo[d]thiazol-2-amine derivatives, which were prepared by reacting benzothiazole with para-aminobenzophenone in ethanol, supplemented with glacial acetic acid. Subsequently, compound (2) was synthesized from compound (1) using NaNO, HPO, and HNO in a water-based solvent, resulting in 2-hydroxy-1-naphthaldehyde. Another derivative, compound (3), was synthesized by reacting compound (1) with vanillin under similar conditions.

Organic hydrides can store hydrogen via chemical bonding under ambient conditions, enabling the safe storage and transportation of hydrogen gas using the same infrastructure for gasoline. However, in previous research, most organic hydrides have been produced from petroleum, and therefore replacing them with earth-abundant or renewable compounds is essential to ensure sustainability. This study demonstrates dihydrolevoglucosenone (CyreneTM), which is a biodegradable liquid ketone that is produced directly from biomass without pretreatments on an industrial scale, as a new renewable organic hydride.

Ice interfaces are pivotal in mediating key chemical and physical processes such as heterogeneous chemical reactions in the environment, ice nucleation, and cloud microphysics. At the ice surface, water molecules form a quasi-liquid layer (QLL) with properties distinct from those of the bulk. Despite numerous experimental and theoretical studies, a molecular-level understanding of the QLL has remained elusive.

The use of precious metals (PMs) in many areas, such as printed circuit boards, catalysts, and target drugs, is increasing due to their unique physical and chemical properties, but their recovery remains a great challenge in terms of zero-valent PMs as final product. We report a highly hydrophilic carbon dot (CD) as reductant (electron donor), the defects in CD served as efficient active sites for zero-valent PMs recovery with an electron-donating capacity is ~1.7 mmol g-1.
