The effect of ionic liquid (IL) constituents and other monovalent salts on the stability of polystyrene latex particles was studied by electrophoresis and light scattering in dilute aqueous suspensions. The surface charge and the aggregation rate were both sensitive to the type of ion leading to different critical coagulation concentration (CCC) values. Systematic variation of the type of IL ca...

Spinning of cellulosic fibers requires the prior dissolution cellulose. 3-Alkyl-1-methylimidazolium ionic liquids have proven to be suitable solvents for that purpose, but degradation cellulose in spinning dope can severe. Suitable stabilizers are therefore required prevent degradation, do not adversely affect spinnability or long-term yellowing behavior fibers. A group twelve renewables-based ...

After overcoming 25% of the power conversion efficiency (PCE) for perovskite solar cells (PSCs), lots efforts are being put into modularization. In order to advance this, development passivation materials that can operate effectively without affecting cell areas is essential. This study introduces 1-decyl-3-methylimidazolium bromide (DMIMB), which an imidazole-based passivator, working well for...

Ionanofluids (INFs) combine the advantages of ionic liquids (ILs) and nanofluids. They are characterized by higher thermal conductivity than pure ILs, as well non-flammability enhanced stability conventional Such an augmentation leads to efficient safe heat transfer fluids. The along with rheological characteristics these hybrid systems profoundly depend on protocol preparation. Therefore, in t...

The title mol-ecular salt, C8H13N2 (+)·Br(-), crystallizes with two independent 3-amino-pyridinium cations and two bromide anions in the asymmetric unit (Z' = 2). In the pyridine ring, the N atom is alkyl-ated by a propyl group. The dihedral angle between the mean planes of the pyridinium ring and the propyl group is 84.84 (2)° in cation A, whereas the corresponding angle is 89.23 (2)° in catio...

A variety of different compounds of fused uracils were prepared simply by the heating of 6-hydrazinyl-1-methyl-, 6-hydrazinyl-1-propyl-, or 6-hydrazinyl-1,3-dipropyluracil under reflux with ninhydrin, isatin, benzylidene malononitrile, benzylylidene ethyl cyanoacetate, benzil, and phenacyl bromide derivatives. The newly synthesized compounds were completely screened for antimicrobial and antitu...

The pH-profiles of the extraction of Cs(+) into four conventional (1-butyl-3-methylimidazolium hexafluorophosphate and bis[trifluoromethyl)sulphonyl]imides of 1-butyl-3-methylimidazolium, 1-hexyl-3-methylimidazolium, and 1-(2-ethylhexyl)-3- methylimidazolium) and two novel (trioctylmethylammonium salicylate and tetrahexylammonium dihexylsulfosuccinate) room temperature ionic liquids have been d...

Extractive fermentation using aqueous biphasic systems (ABS) is a promising separation process since it provides a nondenaturing environment for biomolecules and improves the stability of cells. Due to environmental concerns and toxicity issues related with common volatile organic solvents, ionic liquids (ILs), a new class of nonvolatile alternative solvents, are being currently investigated fo...
