This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

A spin group (SG)‐based mechanism is proposed to realize a single pair of Weyl points. PT‐symmetric nodal lines (NLs) persist under T‐breaking, protected by the combination of SG and P symmetry. When considering spin‐orbit coupling, the SG‐protected NL will split into Weyl points, which will also induce anomalous transport phenomena arising from ...

In this work, the tandem catalyst consisted of single Fe atom and Fe3C nanoparticles on porous carbon sheet is initially proposed and developed to facilitate the dissociation of Li(solvent)x+ to release more isolated Li+ to participate in the subsequent polysulfide redox conversions by decreasing the related barriers, contributing to fast kinetics of ...

A copper‐induced atom ordering strategy is developed for the reconstruction of raw commercial Pt catalyst into ordered PtFeCu intermetallic compounds for hydrogen fuel cells. Abstract Carbon‐supported platinum intermetallic compound nanoparticles are seen as the next‐generation cathodic catalysts for hydrogen fuel cells due to their high activity and ...
