Photoresponsive molecular devices can be a valuable tool to promote chemical changes in response to multiple signals, such as photons and pH, to deliver drugs or to detect physiological conditions in vivo. For example, trans-chalcones (Ct) from 4′-

Vapor-phase molecular simulation studies of aromatic compounds with five or more fluorine atoms on the ring reveal emission spectra characterized by S0 → πσ* and πσ*→S0 transitions. In this study, the absorption, excitation, and solvent-depen

Flavylium ions (6a–6e) were synthesized using Aldol condensation to compare the spectroscopic properties caused by the different numbers and locations of hydroxy groups on the flavylium cations (AH+). Without the addition of acid, increasing the co

First generation dendron bis-1,2-(4-acetylphenylethynyl)-4,5-dimethoxybenzene with a photo cleavable linkage to (t-butyloxycarbonyl-γ-aminobutyric acid (t-Boc-GABA) was synthesized for photo release study to apply for drug delivery. Both the diverge

Summary This paper reviews 10 years of dry-gas miscible-flood operations in three Brazeau River Nisku pinnacle reefs in Alberta. In addition, actual pool performance is compared with the original black-oil-model simulation forecasts. Through June 199

Processes that inject gases such as carbon dioxide and natural gas have long been and still continue to be used for recovering crude oil from petroleum reservoirs. It is well known that the interfacial tension between the injected gas and the crude o
