Ionic liquids (ILs) play an important role in conducting polymer poly(3,4-ethylenedioxythiophene) (PEDOT) based electronics and thermoelectrics through regulating morphology electronic properties.
Ionic liquids (ILs) have received continuous attention owing to their unique chemical and physical properties successful integration in several applications.
We have developed a highly stable supported liquid membrane based on ionic liquids (ILs) for the separation of rare-earth metals, employing N,N-dioctyldiglycol amic acid as a mobile carrier. The quantitative transport of Y and Eu through the membrane was successfully attained, and separation from metal impurities, Zn, was efficiently accomplished. A membrane stable enough for long-term operatio...
Despite many previous important contributions to the characterization of the liquid-liquid phase behavior of ionic liquids (ILs) plus water systems, a gap still exists as far as the effect of isomers (of ILs) is concerned. Therefore, in this work, a comprehensive study of the liquid-liquid equilibria between water and isomeric pyridinium-based ionic liquids has been performed. Atmospheric press...
Ionic liquids (ILs) incorporating cyclic phosphonium cations are a novel category of materials. We report here on the synthesis and characterization of four new cyclic phosphonium bis(trifluoromethylsulfonyl)amide ILs with aliphatic and aromatic pendant groups. In addition to the syntheses of these novel materials, we report on a comparison of their properties with their ammonium congeners. The...
A computational methodology for designing ionic liquids (ILs) with an enhanced water absorption capacity to be used in absorptionrefrigeration systems is presented here. It is based on increasing the hydrogen bond (HB)-acceptor ability of the anion and combining it with a cation that presents a weak cation–anion interaction. Employing this strategy, we identified and prepared three novel dianio...
Ionic liquids (ILs) have been exploited to improve the absorption of poorly water-soluble drugs. Custom-made ILs solubilized very high quantities of the poorly water-soluble drugs, danazol and itraconazole, and maintained drug solubilization under simulated gastro-intestinal conditions. A danazol-containing self-emulsifying IL formulation gave rise to 4.3-fold higher exposure than the crystalli...
1 Ionic liquids (ILs) dissolve lignocellulosic biomass and have a high potential as pretreatment 2 prior to total enzymatic hydrolysis. ILs are, however, known to inactivate cellulases. In this 3 article, enzymatic hydrolysis of microcrystalline cellulose (MCC) and enzyme binding onto 4 the cellulosic substrate were studied in the presence of cellulose-dissolving ionic liquids. Two 5 different ...
In situ labelling and spectroscopic experiments are used to explain the key points in the stabilisation of ruthenium nanoparticles (RuNPs) generated in imidazolium-based ionic liquids (ILs) by decomposition of (eta(4)-1,5-cyclooctadiene)(eta(6)-1,3,5-cyclooctatriene)ruthenium(0), Ru(COD)(COT), under dihydrogen. These are found to be: (1) the presence of hydrides at the RuNP surface and, (2) the...
This work reports a promising approach to the development of novel self-buffering and biocompatible ionic liquids for biological research in which the anions are derived from biological buffers (Good's buffers, GB). Five Good's buffers (Tricine, TES, CHES, HEPES, and MES) were neutralized with four suitable hydroxide bases (1-ethyl-3-methylimidazolium, tetramethylammonium, tetraethylammonium, a...
