Energy-Positive Thiosulfate Production Enabled by Coupling Waste Sulfide Oxidation with Oxygen Reduction
Here we develop a galvanic electrochemical-chemical cascade strategy that couples the sulfide oxidation reaction (SOR) with the two-electron oxygen reduction reaction (ORR), enabling sulfide valorization with net positive electrical energy output.

Multivariate approach of metal-chiral covalent organic frameworks for leaching-resistant asymmetric transfer hydrogenation
Here, we introduce a modular multivariate approach strategy coupled with post-synthetic metalation to engineer metal-chiral COFs (MCCOFs) with tunable crystallinity, porosity, and stereocontrol.

Lattice distortion strain modulation of twin-defective noble-metal-free high-entropy alloy electrocatalyst for Li−O2 batteries
Here, authors demonstrate that lattice strain induced by large-size Ce doping generates coherent five-fold twinning in noble-metal-free high-entropy alloy nanoparticles, which serve as efficient electrocatalysts for non-aqueous Li–O2 batteries.
