Two-electron mediation enables fast alkali peroxide cycling and suppresses side reactions in metal-O2 cells

This paper demonstrates that employing two-electron mediators in aprotic alkali metal–O2 batteries enables direct control over the second electron transfer to form peroxides, thereby suppressing the degradation-causing disproportionation of superoxide intermediates and transforming the reaction mechanism from a difficult-to-control chemical-electrochemical process into a fully mediated electrochemical one.

Effect of Calcination Temperature on the Synthesis of Silicon Carbide from Rice Husk with Copper Additive

This study demonstrates that adding copper as a catalyst enables the efficient synthesis of high-purity silicon carbide from rice husk at significantly reduced temperatures (900–1300°C) via a Vapor–Liquid–Solid mechanism, achieving an 88.47% yield at 1300°C compared to traditional non-catalytic methods requiring temperatures above 1500°C.

Real-time Multi-instrument Autonomous Materials Screening for Discovery of Novel Phase-change Memory Materials

This paper introduces the Multi-instrument Autonomous Discovery (MAD) framework, which integrates heterogeneous data from X-ray diffraction and electrical resistance measurements via a co-regionalized multi-output model to simultaneously optimize structural mapping and functional properties, thereby accelerating the discovery of novel Mn-Sb-Te phase-change memory materials by seven-fold through a closed-loop autonomous process.

In doped NiCo-LDH as bifunctional electrocatalysts for overall water splitting

This study reports a facile one-step electrodeposition strategy to synthesize indium-doped NiCo layered double hydroxides on nickel foam, where an optimal 1.0% In doping creates interstitial defects that enhance electronic structure and active sites, resulting in a highly efficient and stable bifunctional electrocatalyst capable of driving overall water splitting at a low cell voltage of 1.73 V.
