the ionic liquid li(ohch2ch2nh2)(cf3oac) was found to efficiently catalyze the three-component reaction between different enols, aldehydes, and malononitrile , leading to rapid synthesis of 2-amino-4h-chromene derivatives in fairly high yields. the catalyst is easily prepared, highly stable, simple to handle and recycled for several times without significant loss of activity. the method is simp...

a carbon nanocomposite electrode has been designed by incorporation of montmorillonite nanoclayinto the carbon ionic liquid electrode for the electrochemical determination of amitriptiline . the surface ofthe proposed electrode was characterized by scanning electron microscopy. the presence of ionic liquid asa binder is believed to be responsible for the electrocatalytic activity of the propose...

an efficient protocol for the selective oxidation of primary alcohols to aldehydes withh5io6/v2o5 in ionic liquid [bmpy][pf6] has been developed. high yields of the products, mildreaction conditions and simple experimental procedure make this protocol complementary tothe existing methods. the catalyst can be reused for several times without obvious loss of thecatalytic activity.

Simple and low temperature hydrothermal process is employed to synthesize exotic nanostructures of TiO2. The nanostructures are obtained merely by changing the nature of the precursors and processing parameters. The chloride and isopropoxide salts of titanium are used to grow high quality thin films comprising anatase nanocorals, rutile nanorods and rutile nanoflowers respectively. A novel rout...

The adsorption of the perfluoro-sulfonic acid polymer Nafion and ionic liquid (IL) 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide on surface Pt was investigated via voltammetric analyses, using stepped single-crystal electrodes with (111) terraces (110) steps, surface-enhanced infrared absorption spectroscopy (SEIRAS) analyses a polycrystalline electrode. Sulfonate anion in adso...

Abstract Nano-MgO was prepared by microwave irradiated ionic liquid method. The influence of the volume ([BMIM]Ac), radiation power and temperature on morphology nano-MgO were investigated. characterized TG, XRD, EDS SEM. results showed that this method has a short rod-like shape, uniform particle size, good dispersibility. average diameter rod-shaped 25 nm, length 67 specific surface area 48.2...

Abstract In this study, we fabricated nano-capillary emitter arrays for stable ion emission of ionic liquid electrospray thrusters, employing the fabrication field or gated nano electron sources. A was successfully with a 100–300 nm capillary diameter, which prevented leakage by significantly increasing fluidic impedance compared to previously proposed emitter. An experiment conducted 1-ethyl-3...

the density (d), speed of sound (u) and electrolytic conductivity (λ) for systems containing acetaminophen, ionic liquid {1-octyl-3-methyl imidazolium bromide, [omim] br} and water have been measured at t = 293.15-308.15 k. the measured data have been applied to calculate, standard partial molar volume ( ), hepler’s constant , apparent molar isentropic compressibility (kφ), transfer volume ( ),...
