Single-atom catalysts (SACs) — which involve isolated, single metal atoms — have emerged as the next generation of catalysts. Compared to nanoparticles or clusters, SACs provide great activity ...
Single-atom catalysts are defined by their structure where single atoms are dispersed on a suitable substrate, maximizing the exposure of active sites. Unlike nanoparticles or bulk materials, SACs ...
Physicists have now visualized the shape of a photon—the smallest unit of light—using a novel theoretical model. These findings offer new insights into how light behaves, potentially paving the way ...
