It has been shown that the use of mixed high/low vapor pressure solvents can surpass the minimum fiber diameter achieved in electrospinning. N-methyl pyrrolidone (NMP) is added to N, N-dimethylformamide (DMF) in different weight ratios (0/100, 25/75, 50/50, 75/2...
The dependence of the ratio Ks/Ke (equations 24 and 25) on the solvent vapor pressure P0;8 (○), experimental data for unbranched alkanes and tristearin in various solvents; (▴) calculated points from equation (24) by putting (k1A1+k2A2)/(k3A1)=6 × 107 cal dyne−1 mol−1...
Anti-solvents, such as diethyl ether (P: 2.9), chlorobenzene (P: 2.7), and toluene (P: 2.4), are high-vapor-pressure solvents with low polarity indices that are miscible with dispersion solvents but not with perovskites. They enable the rapid removal of excessive high-solvation solvents ...
It has good chemical stability, resistance to alkali and general organic solventsLinear low-density polyethylene (LLDPE) is non-toxic, tasteless and odorless milky white particles with a density of .918~0.935g/cm3. Compared with LDPE, it has a higher softening temperature and ...

One of the main classes investigated, volatile aliphatic esters, are biologically ubiquitous, maintain unique fragrant properties, and serve as additives in cosmetics, food, solvents, coatings, and as biofuels [4, 5]. Ester bioproduction is attractive due to the relative ease with which alcohols an...
Chemical stability: PFA material has excellent chemical stability and can resist a wide range of chemicals, including strong acids, strong bases and organic solvents. High temperature resistance: PFA acid purifier can operate at high temperatures, usually with a...
The pre-wetting method using DMF/DMSO solvents is also beneficial for alleviating the problems caused by the non-wettability of the PTAA surface48. However, the effect of this method on improving wettability is not obvious because most DMF/DMSO solvents evaporate quickly during the rapid spin-...

Ionic liquids (ILs) are potential green alternatives to volatile organic solvents due to their negligible vapor pressure and volatility. Most ILs absorb gases via a physical mechanism, therefore the solvent regeneration step requires less energy in comparison to processes with chemical absorption such as...
