Summary: In this study, a ternary photocatalyst of g-C3N4/Ag-TMCs was prepared by photodepositing Ag nanoparticles on the surface of titanium dioxide mesocrystals followed by loading them on g-C3N4. The prepared photocatalyst exhibited excellent photocatalytic activity and the deposited Ag content positively influenced the photocatalytic degradation efficiency. The improved photocatalytic properties were attributed to the synergistic effect created by the LSPR effect of Ag, electron-conduction bridge role of Ag, and the heterojunction structure formed between Ag, TMCs, and g-C3N4.

Summary: Composite cathodes consisting of LiNi0.8Co0.1Mn0.1O2 (NCM) and Li3InCl6 (LIC) are investigated for all-solid-state Li-ion batteries (ASSLIBs). The particle morphologies of NCM cathode materials affect the internal cracking within the composite electrodes and consequently the electrode performance. High current rates result in widespread microcracking in polycrystal NCM particles, while single-crystal NCM particles show fewer grains and better contact with the solid-state electrolytes (SSEs). A low-pressure single-crystal NCM ASSLIB exhibits good cycle stability comparable to liquid-electrolyte cells.

Summary: In this study, a new low density electrolyte based on hexyl methyl ether (HME) and 1,3-dioxalane (DOL) was introduced, which allows the use of graphite as anode material for Li-S batteries. By using symmetric graphite vs. graphite cells, an average Coulombic efficiency of 99.94% per electrode could be achieved. Furthermore, the cycling conditions for Li-S cells with graphite anodes were optimized for the first time, and the feasibility of the concept was demonstrated in multilayer pouch cells under realistic conditions.

Summary: The interfacial photocatalysis of metal oxide electron transport layers (ETLs), especially TiO2, in organometal halide perovskite solar cells (PSCs) has detrimental effects on device stability. A UV absorber, 4,4'-oxybisbenzoic acid (OBBA), was used as a modification layer between TiO2 and perovskite to prevent UV photocatalytic degradation. The modified device showed a high power conversion efficiency (PCE) of up to 22.14% and excellent stability under extreme UV irradiation (365 nm, 600 mW cm(-2); 275 nm, 10 mW cm(-2)).

Summary: To improve the performance of perovskite solar cells (PSCs), researchers have used passivators to address the defects of perovskite. In this study, a passivator called TA-MN, which has a symmetric bidentate acceptor, was found to have a strong synergistic passivating ability due to the presence of two symmetric cyano groups (CN). This passivator achieved a higher power conversion efficiency (PCE) of 21.19% compared to the TA-CA passivator (20.54%) and the control group (19.49%). The TA-MN-based PSCs also demonstrated good stability and scalability. These findings provide useful insights for the design of passivators with symmetric bidentate acceptors.

The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
