One-Step Solid-State Reactions at Ambient Temperature -A Novel Approach to Nanocrystal Synthesis.-A general and solvent-free procedure is developed to produce nanocrystals in over 90% yield. Nanocrystals of oxides (CuO), sulfides (CuS, ZnS, CdS, PbS)Ni, Mn, Co, Zn)], carbonates (MCO 3 , M: Ca, Ba), and salts of 8-hydroxyquinoline (HOxin) [M(Oxin)x (M: La, x = 3; M: Zn, x = 2)] are prepared at ambient temp. through rapid (10 s to 30 min), self-propagating solid state metathesis reactions of hydrated transition…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
