Advanced Science, EarlyView.Fe@WO3/ZnCo2O4 n‐p heterojunction sensor exhibits excellent room‐temperature sensing toward tetradecane, with a low detection limit of 78.4 ppb and short recovery time. The good performance is attributed to synergistic effects from heterojunctions, heteroatom doping, oxygen vacancies, high‐energy facets, and theoretical validations.

Advanced Science, EarlyView.A novel sunlight‐driven synthesis produces Ag–Cu bimetallic nanoparticles (NPs) in just 10 min using nontoxic surfactants. These high‐quality NPs show excellent catalytic activity, functioning as reusable polytetrafluoroethylene (PTFE) and activated carbon fiber (ACF) supported catalysts for efficient conversion of p‐nitrophenol to p‐aminophenol, and ...

Packaging Metal Atomic Clusters for Universal and Robust Protection through Cluster Beam Process
Advanced Science, EarlyView.Gas‐phase‐aggregated metal clusters are packaged and well‐protected in poly(methyl methacrylate) (PMMA) through controlled beam implantation. The packaged precise clusters show robust protection against oxidation and agglomeration. This protection also demonstrates universality, as it successfully protects metal clusters composed of various elements ...
