we performed molecular dynamics simulations using the coarse-grained model to study the freezing behavior of pure water and 14% water-salt mixture in a wide range of temperatures for a very long time around 50 nanoseconds. for the salty water, an interface in nanoscale was used. for both systems, the freezing behavior of water molecules was studied using some qualities such as density, total en...

water plays a vital and essential role in our ecosystem. this natural resource is becoming scarce, making its availability a major social and economic concern. use of a large variety of synthetic dyes in textile industries has raised an hazardous environmental alert. about 17 - 20% of freshwater pollution is caused by textile effluents. these effluents are recalcitrant to biodegradation and cau...

active carbons were produced from bagasse, millet and sorghum straws by chemical activation with h3po4. carbon precursors with particle size of 1180 î¼m were used, in order to overcome difficulties caused by low density and high ash content. the influence of preparation conditions (temperature, residence time, and acid impregnation ratio) on the yield of the active carbons was examined. the imp...

in this work, a molecular dynamics simulation of the transport of water - methanol mixture through the single wall carbon nanotube (swcnt) is reported. methanol and water are selected as fluid molecules since water represents a strongly polar molecule while methanol is as an intermediate between polar and strongly polar molecules. some physical properties of the methanol-water mixture such as r...

Lower critical solution temperature (LCST) phase transition of glycol ether (GE)-water mixtures induces an abrupt change in osmotic pressure driven by a mild temperature change. The temperature-controlled osmotic change was applied for the forward osmosis (FO) desalination. Among three GEs evaluated, di(ethylene glycol) n-hexyl ether (DEH) was selected as a potential FO draw solute. A DEH-water...
