Cu‐Pd Dual Single Atoms Promoting Selective CO2 Photoreduction to C2 Products in Seawater
Cu and Pd dual single atoms anchored on TiO2 cooperatively enhance C─C coupling during CO2 photoreduction in seawater. Under xenon‐light irradiation and without a sacrificial reagent/alkaline trapping agent, the catalyst achieves highly selective acetic acid formation.

GRAIN-BOUNDARY SULPHUR SEGREGATION AND EMBRITTLEMENT OF HIGH-PURITY NICKEL
Sulphur grain boundary segregation in vacuum-melted nickel of a special production probe were studied by Auger Electron Spectroscopy. Heat-treated samples of high-purity Ni were electrolytically deuterium doped and fractured by tension and measuring the

Gold‐stabilized copper suppresses hydroxide‐driven deactivation during anodic hydrogen evolution from furfural. Pairing this low‐potential anode with CO‐to‐ethylene electroreduction enables sub‐1 V operation at 400 mA cm−2, high single‐pass CO conversion, and co‐production of ethylene, furoic acid, and a separate hydrogen stream.

Engineering Exciton g‐Factors With Light in Type‐II Heterostructures
All‐optical approaches have emerged as cutting‐edge alternatives for ultrafast, energy‐efficient, and spatially localized tuning and switching of material properties. In our work, we demonstrate how light intensity alone can be leveraged to engineer g‐factors from a single‐type of carrier in type‐II heterostructures through Coulomb‐induced wavefunction
