Ferrofluids based on maghemite nanoparticles (NPs), typically 10 nm in diameter, are dispersed an ionic liquid (1-ethyl 3-methylimidazolium bistriflimide – EMIM-TFSI).

ethylammonium propionate with high polarity and ionic conductivity was synthesized andcharacterized with 1hnmr and ir. this ionic liquid which is prepared from readily available startingmaterial in high yield shows reasonably high at viscosity and heat stability up to 150 °c. this ionicliquid is able to dissolve most of organic solvents due to the hydrogen interaction between ionicliquid and th...

In this study, an easy, fast, sensitive and accurate technique has been described for extraction and quantitative analysis of fluoxetine and propafenone using off-line coupling of ionic liquid–based dispersive liquid–liquid micro-extraction with high performance liquid chromatography. The effective extraction variables including: the ionic liquid volume, the type and volume of dispersive solven...

in this work, reactive absorption of gases in aqueous electrolyte solutions has been investigated resulting in the development of a procedure in order to calculate the concentrations of ionic and molecular species in the liquid phase. two duplicate experiments were conducted to investigate simultaneous reactive absorption of ammonia and carbon dioxide in partially carbonated ammonia solutions. ...

Topological insulators with broken time-reversal symmetry and the Fermi level within magnetic gap at Dirac cone provides exotic topological magneto-electronic phenomena. Here, we introduce an improved magnetically doped insulator, Fe-doped BiSbTe2Se (Fe-BSTS) bulk single crystal, ideal level. Scanning tunneling microscopy spectroscopy (STM/STS) measurements revealed that surface state possesses...

A simple and mild procedure for the conversion of anilines into aryl isocyanates is described using the 3-hydroxypropylammonium acetate (HPAA) ionic liquid as a novel and efficient media has been explored in the synthesis of aryl isocyanates from the reaction of substituted urea with sodium nitrite in a water immiscible solvent. This ionic liquid can be easily recovered and reused for many time...

An ionic liquid "reagent" bearing a succinimidyl activated ester is reported that can be used to synthesize a variety of small molecule and macromolecular ionic liquids. In addition, the ionic liquid reagent was used to modify lysozyme, and the protein retained its structure and function after modification. This study describes a facile and reliable route to new ionic liquid compositions.
