Suppressing Aluminum Self-Corrosion and Hydrogen Evolution in Alkaline Aluminum–Air Batteries via Stable Interfacial Reorganization and Hydrophobic Shielding Induced by Tetrabutylphosphonium Methanesulfonate

This study demonstrates that tetrabutylphosphonium methanesulfonate (TBPMS) acts as an effective multifunctional additive in alkaline aluminum–air batteries by forming a stable, hydrophobic interfacial layer that significantly suppresses aluminum self-corrosion and parasitic hydrogen evolution through interfacial reorganization and surface smoothing.

Fabrication and H2S gas sensitive performance of NiO ultrathin film encapsulated VO2(A) nanowire core-shell heterojunction structure

This study demonstrates that a NiO ultrathin film encapsulated VO2(A) nanowire core-shell heterojunction, fabricated via chemical precipitation and annealing with a 1:0.5 precursor molar ratio, achieves high sensitivity and rapid response/recovery for H2S gas detection at 100°C due to the synergistic effects of the heterojunction and NiO's catalytic activity.
