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 ...
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 ...
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 ...
Scientists have created the world's thinnest gold leaf, which is just a single atom thick ... with the gold atoms coagulating into nanoparticles as soon as the support was removed.
A zinc oxide nanoparticle has a diameter of 32 nm. The diameter of a zinc atom is 0.28 nm. Estimate how many times larger the nanoparticle is compared to a zinc atom. A cube-shaped nanoparticle ...
Methods: We developed a novel method to analyze stacks of confocal fluorescence images of single cells interacting ... uptake of 80-nm mesoporous silica nanoparticles into HeLa cells.
