The result of MD simulations presented the clear superheating phenomenon of pure liquid diethyl ether system in the studied environment. The obtained phase transition point was much higher than the reported one. The deviation between two temperatures was about 132.369K. It was also demonstrated that ...
We investigated the effect of various mixtures of diethylether, halothane, nitrous oxide and oxygen on the intracellular LMWI content and mitochondrial function of the rat myocardium. 展开 关键词: Nitrous oxide halothane oxygen radicals mitochondria iron diethylether ...
Briefly, lipids (POPC:POPG 3:1 molar ratio) were pooled, dried using rotary evaporator, and washed with diethyl ether. After diethyl ether was evaporated, the lipids were rehydrated in ND buffer (20 mM HEPES, 150 mM NaCl and 30 mM DDM) at a concentration of 10 mM. Purified ...
The calculated amount of ZnBr2 in diethyl ether or TiCl4 in toluene was added and stirred for 1 h at room temperature. The solution of PCL-OTMS in toluene was then added into the mix- ture and subject to react for 150 h at 60◦C on an oil bath. The polymer was collected by re...
Deprotection of the γ-Benzyl was performed in 4 equivalents (per carboxylic group) of 33% HBr in acetic acid and trifluoroacetic acid (TFA) at 1:1 (v:v) ratio for 1 h. The resulting PGA was precipitated in cold diethyl ether as the free acid. The precipitate was washed with acetone ...
Upon treatment with silicate-dissolving diethyl ether, >90% of 1H signals from the silicate cargo are retained, indicating that most of these cargos are well-protected and encapsulated nanoparticle core. Aside from the biodegradable and biocompatible synthetic polymers, polyethyleneimine (PEI) is ...
reaction, the chlorinated silicon compound is preferably used after diluting it with the inert hydrocarbon solvent, a chlorinated hydrocarbon such as 1,2-dichloroethane, o-dichlorobenzene, or dichloromethane, an ether-based medium such as diethyl ether or tetrahydrofuran, or a mixed medium of them. ...
3. A solid catalyst precursor as in claim 2 wherein the silicon containing molecular weight distribution regulator is tetraethoxysilane. 4. A solid catalyst precursor as in claim 2 wherein the silicon-containing molecular weight distribution regulator is diethyldiethoxysilane. ...
Commercial surfactants, including polyoxyethylene ether, petroleum sulfonate, and alky benzyl sulfonate, face stability issues when encounters with the harsh environment of the reservoir. In this work, we report the synthesis of four dicationic surfactants (DSs) that contain different lipophilic tail and...
Here we report that the tri-1-adamantylphosphine-nickel complex [Ad3PNiBr3]-[Ad3PH]+ upon activation with an alkylaluminoxane catalyzes the polymerization of ethylene to ultrahigh-molecular-weight, nearly linear polyethylene (Mn up to 1.68 × 106 g mol−1) with initial activities ...
