The lack of suitable nonflammable electrolytes has delayed battery application in electric vehicles. A new approach to improve the safety performance for lithium battery is proposed here. This technology is based on a nanogelator-based solid electrolyte made of porous oxides and an ionic liquid. The electrolyte is fabricated using an in situ method and the porous oxides serve as a nonflammable ...

The solvation and rotational relaxation dynamics of coumarin 153 have been investigated in a dicationic ionic liquid (IL), 1,6-bis-(3-methylimidazolium-1-yl)hexane bis-(trifluoromethylsulfonyl)amide ([C6(MIm)2][NTf2]2), for the first time to provide a comprehensive and a quantitative understanding of the nature of the ionic fluid and its influence on the average solvation and rotational relaxat...

Dynamic tribochemical processes for dicationic ionic liquid containing a geminal imidazolium cation head group bridged by a poly(ethylene glycol) and a bis(trifluoromethylsulfonyl)imide anion were studied using time-resolved mechanically stimulated gas emission mass-spectrometry (MSGE-MS). In comparison with similar monocationic imidazolium ionic liquids with short alkyl or long polyether side ...

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...

Liquid-liquid extraction is an alternative method that can be used for desulfurization and denitrification of gasoline and diesel fuels. Recent approaches employ different ionic liquids as selective solvents, due to their general immiscibility with gasoline and diesel, negligible vapor pressure, and high selectivity to sulfur- and nitrogen-containing compounds. For that reason, five imidazolium...

Dynamic tribochemical processes for dicationic ionic liquid containing a germinal 14 imidazolium cation head groups bridged by a poly(ethylene glycol) and 15 bis(trifluoromethylsulfonyl)imide anion were studied using time-resolved Mechanically 16 Stimulated Gas Emission Mass-Spectrometry (MSGE-MS). In comparison with similar 17 monocationic imidazolium ionic liquids with short alkylic or long p...

We employ, for the first time, a shell-isolated nanoparticle-enhancement strategy to extend Raman spectroscopy studies to single crystal electrode surfaces in ionic liquids, and combine density functional theory (DFT) calculations to elucidate the structural details of the imidazolium-based ionic liquid-Au single crystal electrode interfaces.

In this article, we describe an efficient synthetic pathway and the characterization of liquid crystal luminescent imidazolium salts based on a naphthalene unit. The imidazolium-naphthalene rigid part is decorated with benzyl group functionalized by two or three dodecyloxy chains. A crystalline structure shows unambiguously segregation between ionic flexible parts conducive to emergence mesomor...

in this thesis protic and aprotic ammonium-based ionic liquids were synthesized and their surface tensions were measured in the range of 298-373k. the protics are alkyl ammonium-based ils with the carboxylate (formate, acetate, propionate) anion and aprotics are quaternary ammonium-based ils with bis(trifluoromethylsulfonyl)imide anion. capillary rise method was used for surface tension measure...
