The role of dispersion type metal[middle dot][middle dot][middle dot][small pi] interaction in the enantiotropic phase transition of two polymorphs of tris-(thienyl)bismuthine

13.09.2017 | Ana Maria Preda; Wolfgang B. Schneider; Dieter Schaarschmidt; Heinrich Lang; Lutz Mertens; Alexander A. Auer; Michae ..., Dalton Transactions, 2017

Two polymorphs of the tris(thienyl)bismuthine Bi(2-C4H3S)3 (1) were isolated upon crystallization from n-hexane at different temperatures. The high temperature form 1-HT crystallized at 269 K in the trigonal space group R-3 whereas the low temperature form 1-LT crystallized at 245 K in the ...

Gold nanoparticles optical properties induced by water and ionic liquid (bmimBF4) inside cationic reverse micelles.

13.09.2017 | Diana Blach; Fernando Martínez, New Journal of Chemistry, 2017

In this work we report the effect of the polar solvent entrapped on benzyl-n-hexadecyldimethylammonium chloride (BHDC) reverse micelles (RMs), as nanoreactors for gold nanoparticles (AuNPs) synthesis. We have evaluated how the room temperature ionic liquid (RTIL) 1-butyl-3-methylimidazolium ...

Origin of spray formation during impact on heated surfaces

13.09.2017 | Michiel Antonius Jacobus van Limbeek; Paul Hoefnagels; Chao Sun; Detlef Lohse, Soft Matter, 2017

In many applications it is crucial to control the heat transfer rate of impacting drops on a heated plate. When the solid exceeds the so-called Leidenfrost temperature, an impacting drop is pre- vented from contacting the plate by its own evaporation. As the decrease in the resulting cooling ...
