The key aroma compounds and the organoleptic quality of two Chinese Syrah wines from the Yunnan Shangri-La region and Ningxia Helan mountain region were characterized. The most important eighty aroma-active compounds were identified by Gas Chromatography-Olfactometry. In both Syrah samples, ethyl 2-methylpropanoate, ethyl 3-methylbutanoate, 3-methylbutyl acetate, 2- and 3-methyl-1-butanol, ethy...

Possibility of silver nanoparticle synthesis by reduction of silver trifluoro acetate inorganic media (ethylene glycol, 2-methoxyethanol, ethyl acetate) was studied. Quercetin, ascorbicacid and potassium citrate were used asreducing agents.

Dendron rod-coil molecules are a novel supramolecular building block, comprising a dendritic unit, a rodlike unit, and a coil unit (J. Am. Chem. Soc. 2001, 123, 4105). It was proposed that in solution these molecules assemble into ribbonlike aggregates of high aspect ratio. We report here on the self-assembly of DRC-molecules in 2-propanol and ethyl acetate as studied with static and dynamic li...
