Smaller nonmetallic nanoparticles are more inert: Metal-insulator transition of Au nanoparticles on silica is closely related to the metal-support charge transfer, which has a strong influence on chemisorption reactivity of Au. Smaller nonmetallic Au

As predicted by Moore’s Law, [1] the feature size of semiconductor devices reached the 90 nm node in 2004. [2] Presently, research is focused on reaching 32 nm. [3] Unfortunately, standard UV lithography cannot be used at this scale. [3] Thus, seve
