Electrochemical method can be useful for the determination of diffusion coefficients in various media. For low polarity media, ultramicroelectrodes are preferably used. In this work, the electro-oxidation of ferrocene has been studied in dimethylformamide (DMF)–CO2 mixtures under various CO2 pressures, using a 100 lm diameter Pt microelectrode. Tetrabutylammonium perchlorate (TBAP) was chosen a...

An affinity ionic liquid, based on biomolecular recognition, was developed and found to be capable of quantitative partitioning of biomacromolecules from aqueous buffer to ionic liquid.

Dispersion of graphene sheets in ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate was successfully achieved with the aid of a polymerized ionic liquid (PIL).

High pressure behaviour of Na-hectorite in water media shows surprisingly strong similarities to graphite oxide compression in liquid media considering rather different chemical composition and structure of these two types of materials. Crystalline swelling with pressure induced insertion of additional solvent layer (not correlated with pressure point of liquid media solidification) was observe...

Studying the interaction of pharmaceutical ionic liquids with human serum albumin (HSA) can help investigating whether or not ionic liquid formation can enhance pharmacological profile of the discrete ingredients. In this respect, in the present work, the interactions of Benzalkonium Ibuprofenate, as a well-known active pharmaceutical ionic liquid, Benzalkonium Chloride, and also Sodium Ibuprof...

In this communication, we report the coexistence of liquid and solid phases of room temperature ionic liquid (IL) [Bmim][PF6] on mica surfaces, observed by tapping mode atomic force microscopy (AFM) in air. Multilayers as well as drop-on-the-layer structures of the ionic liquid are revealed. The solid layers were very stable, and their orientations were affected by the mica lattice, indicating ...

Isolated ion pairs of a conventional ionic liquid, 1-Ethyl-3-Methyl-Imidazolium Bis(trifluoromethylsulfonyl)imide ([Emim(+)][Tf(2)N(-)]), and a reactive hypergolic ionic liquid, 1-Butyl-3-Methyl-Imidazolium Dicyanamide ([Bmim(+)][Dca(-)]), are generated by vaporizing ionic liquid submicrometer aerosol particles for the first time; the vaporized species are investigated by dissociative ionizatio...

In this study, a novel acidic magnetic dicationic ionic liquid was prepared in three steps to serve as a green  catalyst  in  organic  synthesis.  The  newly  synthesized  catalyst  was  characterized UV- VIS,  and  VSM  analysis.  Additionally,  the  decomposition  steps  acatalyst  were investigated by thermal  analysis  techniques  (TGA/DSC).  The  synthesized  acidic magnetic dication...

The electrochemical behavior of a redox-active, ferrocene-modified ionic liquid (1-ferrocenylmethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide) in acetonitrile and in an ionic liquid electrolyte (1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide) is reported. Reversible electrochemical behavior was observed in each electrolyte with responses typical of those for unmodifie...
