Bulk nanobubbles which are usually observed in pure water have a mean diameter typically around 100 nm. We use combination of physical and chemical techniques to prove the hypothesis that nanoentities stable clusters much smaller nanobubbles. The stability bulk nanobubble is affected by factors such as ionic strength or internal energy system. show on order nm exist cluster form neutral basic m...

The thermal stability of SAMs generated from the adsorption of n-octadecanethiol (n-C18), 2-hexadecylpropane-1,3-dithiol (C18C2), 2-hexadecyl-2-methylpropane-1,3-dithiol (C18C3), and 1,1,1-tris(mercaptomethyl)heptadecane (t-C18) on colloidal gold and evaporated "flat" gold was investigated. The optical extinction of the monolayer-protected nanoparticles (MPCs) was monitored as a function of the...
