Efficient Low‐temperature Ammonia Cracking Enabled by Strained Heterostructure Interfaces on Ru‐free Catalyst

Advanced Materials, EarlyView.
Leveraging the strong metal‐support interaction effect, heterostructured interfaces in a Co‐based catalyst are designed to enable low‐temperature ammonia (NH3) decomposition. The induced tensile lattice strain within the core‐shell structure modulates d‐band center of Co, enhancing NH3 adsorption and facilitating N─H bond dissociation. Furthermore, the

Engineered Plasmonic and Fluorescent Nanomaterials for Biosensing, Motion, Imaging, and Therapeutic Applications

Advanced Materials, EarlyView.
A schematic illustration of how noble metals can be used to create nanoparticles (NPs) or nanoclusters (NCs). Noble metal NPs, due to their plasmonic properties, enable photothermal therapy and surface‐enhanced Raman scattering (SERS). In contrast, NCs, which lack a plasmonic resonance band, exhibit fluorescence, making them ideal for bioimaging ...
