The crystal growth process in colloidal nanocrystal systems is usually associated with the Ostwald-ripening mechanism. Here, we report on experimental evidence indicating that another took place a system at room temperature. This based grain rotation among neighboring grains, resulting coherent grain–grain interface, which, by eliminating common boundaries, causes grains to coalesce, thereby forming single larger nanocrystal. phenomenon was observed SnO2 nanocrystals (particle size ranging...
Thom's catastrophe theory applied to the evolution of topology electron localization function (ELF) gradient field constitutes a way rationalize reorganization pairing and powerful tool for unambiguous determination molecular mechanisms given chemical reaction.

The paper collects the answers of authors to following questions: Is lack precision in definition many chemical concepts one reasons for coexistence partition schemes? Does adoption a given scheme imply set more precise definitions underlying concepts? How can use results improve clarity Are schemes subject scientific Darwinism? If so, what is influence community's sociological pressure "natural selection" process? To extent does/can/should investigated systems choice particular scheme? Do...
A combined experimental and theoretical study was conducted on the structure electronic properties of α-Ag2WO4 to clarify nucleation growth processes Ag filaments crystals induced by electron beam irradiation under microscopy.
