in this research using the theory of induction motor (um), a um with liquid as secondary part is planned and manufactured. the main objective for planning of this motor is to investigate the possibility of chemical liquids pumping such as liquid poison and acids. results of many laboratory tests are shown to conclude that pumping force in the manufactured pump is dependent on many factors su...

A new class of compounds, called as ionic liquids, has recently emerged as potential substitute for volatile organic solvents. Ionic liquids possess certain special physico-chemical characteristics that render them very useful in different areas of research and development. In this review, the physico-chemical properties and the applications of ionic liquids in chemical processes are critically...

Following the success of electronic noses in a variety of applications related to many areas such as industrial, medical, environmental, spatial, etc. where the objective was to construct chemical images of volatile compounds including odors, here we introduce another system able to perform chemical images of liquids of different origin, quality, and composition. In line with mammalian senses s...

Ionic liquids have favorable intrinsic properties that make them of interest as solvents for various chemical reactions. The same properties that make the liquids effective solvents also make them interesting liquids for studies involving sonochemistry, acoustic cavitation, and sonoluminescence. Recent interest in using ultrasound to accelerate chemical reactions conducted in ionic liquids nece...

in recent years, ionic liquids have been used in pharmaceutical processes. therefore, having a deep insight into the ion association behavior of ionic liquids in the presence of a drug is of particular importance. so, in this work, the molar conductivities of the ionic liquids, 1-alkyl-3-methylimidazolium bromide, [cnmim]br (n = 4, 6 and 8) in various concentrations of aspirin (asa) in acetonit...

Imidazole-based energetic ionic liquids capable of dual-mode chemical monopropellant or bipropellant and electric electrospray rocket propulsion are investigated. A literature review of ionic liquid physical properties is conducted to determine an initial set of ionic liquids that show favorable physical properties for both modes, followed by numerical and analytical performance simulations. Of...

A systematic study of the physico-chemical properties of a series of new catanionic surfactants with ionic liquid properties is reported. Importantly, by avoiding environmentally unfriendly halide and imidazolium based moieties highly tunable surfactant ionic liquids have been prepared.

We present a colourimetric litmus test for simple differentiation of organic liquids based on wetting, which achieves chemical specificity without a significant sacrifice in portability or ease-of-use. Chemical specificity is derived from the combination of colourimetric wetting patterns produced by liquids in an array of inverse opal films, each having a graded wettability, but using different...

A QCM device employing ionic liquids as the sensing materials for organic vapors has been developed and evaluated. The sensing mechanism is based on the fact that the viscosity of the ionic liquid membrane decreases rapidly due to solubilization of analytes in the ionic liquids. This change in viscosity, which varies with the chemical species of the vapors and the types of ionic liquids, result...
