Microporous polymers based on anionic macroinitiator and toluene 2,4-diisocyanate were used as a support for 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]) and 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([emim][Tf2N]) immobilization. The polymeric support was modified by using silica particles associated in oligomeric media, and the influence of the modifier used on the polymeric structure was studied. The supported ionic liquid membranes (SILMs) were tested for He, N2, NH3, H2S, and CO2 gas separation and ideal selectivities were calculated. The high values of ideal selectivity for ammonia-based systems with permanent gases were observed on polymer matrixes immobilized with [bmim][PF6] and [emim][Tf2N]. The modification of SILMs by nanosize silica particles leads to an increase of NH3 separation relatively to CO2 or H2S.

Ionic liquids (ILs) are widely used in diverse scientific and industrial fields, yet many of these substances exhibit significant cytotoxicity, challenging their classification as “green solvents”. To facilitate access to established experimental cytotoxicity data on ILs, we present ILToxDB - a curated, open-access database containing 3844 cytotoxicity assay entries for 1224 ILs tested across 154 ...

The following article focuses on several points. First, it deals with the research of phraseological units and precedent expressions, second, with the elaboration of possible distinctions between them, since these linguistic units are close to each other. Phraseological units are structurally separable units, which possess sustainability and reproducibility, and which have absorbed implicit cultural meanings. ...

Throughout human history, the progress of human society has invariably been accompanied by more efficient utilization of energy. Currently, approximately 15 % of the total energy consumed by humans is utilized in the process of separating and purifying substances. Therefore, novel separation methods are urgently needed. In the field of gas separation, emerging membrane separation and ...

The weak point of ionic liquids is their high viscosity, limiting the maximum polymer concentration in the forming solutions. A low-viscous co-solvent can reduce viscosity, but cellulose has none. This study demonstrates that dimethyl sulfoxide (DMSO), being non-solvent for cellulose, can act as a nominal co-solvent to improve its processing into a nanofiltration membrane by ...

rganosubstituted silica derivatives were synthesized and investigated as modifiers of block copolymers based on macroinitiator and 2,4-toluene diisocyanate. A peculiarity of the modified block copolymers is the existence in their structure of coplanar rigid polyisocyanate blocks of acetal nature (O-polyisocyanates). Organosubstituted silica derivatives have a non-additive effect on high-temperature relaxation and α-transitions of modified polymers ...

A novel triphenylamine derivative-linked ionic liquid unit, 1-(6-((4-(bis(4-(thiophen-2-yl)phenyl)amino)benzoyl)oxy)hexyl)-3-methyl-imidazolium tetrafluoroborate (TTPAC6IL-BF4), was designed and synthesized successfully, and its corresponding polymer PTTPAC6IL-BF4 was obtained by the electropolymerization method. The highest occupied molecular orbital energy band of TTPAC6IL-BF4 is higher and the onset oxidative potential lower compared with that of 6-bromohexyl 4-(bis(4-(thiophen-2-yl)phenyl)amino) benzoate (TTPAC6Br) without modifying the ionic ...

В статье рассмотрена идея телесной модификации как эмансипаторной практики, которую можно обнаружить в работе Негри и Хардта "Империя".Теоретики считают телесные преобразования первым признаком антропологического исхода - трансформации субъекта, которая способна избавить его от капиталистической эксплуатации. С целью проблематизации этой идеи мы обращаемся к телесным мотивам в творчестве Кроненберга. ...
