Solid-State Lithium Batteries In article number 2201762, Maoxiang Jing, Xiangming He, and co-workers report a composite solid-state electrolyte (CSE) formed by in-situ polymerization of 1.3-dioxolane (DOL) catalyzed nano yttria stabilized zirconia. Excellent cycle stability provides new research idea for the practical application PDOL based CSE at high voltage.
Aluminosilicates Catalysts Synthesis from Low-Grade Indonesian Kaolin for the Acetalization Reaction
Aluminosilicate and ZSM-5 catalyst were synthesized from local materials, low-grade Indonesian kaolin. High quartz impurities content in the kaolin was successfully reduced by consecutive treatment process including washing, centrifugation, Fe3+ treatment. All showed mesoporous structure with pore diameter around 3.5 nm. The catalytic activity investigated acetalization of 3,4-dimethoxybenzalde...
The total synthesis of plakortide E (1a) is reported. A novel palladium-catalyzed approach towards 1,2-dioxolanes as well as an alternative substrate-controlled route leading exclusively to cis-highly substituted 1,2-dioxolanes have been developed. A lipase-catalyzed kinetic resolution was employed to provide optically pure 1,2-dioxolane central cores. Coupling of the central cores and side cha...
IN THE CRYSTAL STRUCTURE OF THE TITLE COMPOUND [SYSTEMATIC NAME: 2-(4b-fluoro-5-hy-droxy-4a,6a,8,8-tetra-methyl-2-oxo-2,4a,4b,5,6,6a,9a,10,10a,10b,11,12-dodeca-hydro-7,9-dioxa-penta-leno[2,1-a]phenanthren-6b-yl)-2-oxoethyl acetate], C(26)H(33)FO(7), the mol-ecules are connected by inter-molecular O-H⋯O hydrogen bonds into an infinite supra-molecular chain along the b axis. The mol-ecular framew...
