• Mechanisms behind enhanced CO 2 /CH 4 gas mixture selectivity are explored from the aspect of aperture configurations. Variation pristine configuration gives lower selectivity. Addition ionic liquids improves stability apertures and hence enhances separation efficiency. Viscosity ILs can affect stability, with viscosities smaller than 90 Cp. using (ILs) encapsulated metal-organic frameworks (...

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...

We discuss the dependence of phase diagram a hypothetical isotope helium with nuclear mass less than 4 atomic units. argue that decreasing nucleus mass, temperature superfluid transition (about 2.2 K in real He-4) increases, while liquid-gas critical point 5.2 decreases. various scenarios may occur when two temperatures approach each other and order parameters transitions interact other. The si...

Liquid hydrogen (LH2) spills share many of the characteristics liquefied natural gas (LNG) spills. LNG on water sometimes result in localized vapor explosions known as rapid phase transitions (RPTs), and are a concern industry. LH2 RPT is not well understood, its relevance to safety be determined. Based established theory from research, we present theoretical assessment an accidental spill cryo...

The sonication of ionic organic liquids leads to decomposition of the liquids. Multibubble sonoluminescence spectra and headgas analysis reveal a variety of decomposition products from the sonolysis of N,N'-dialkylimidazolium ionic liquids. The decomposition is a result of acoustic cavitation, which generates localized hot spots from the implosive collapse of bubbles in the ionic liquids. Despi...

In recent years there has been a great deal of attention paid by researchers in investigating ionic liquids (ILs) mainly due to the tremendous potential that ionic liquids have in reaction and separation technology. Sonic speed is an important thermodynamic property of ionic liquids (ILs) and always chosen as a source to determine other properties. A database for the sonic speed of pure ILs cre...

the antibacterial activity of a series of ionic liquids containing short-chained 1-alkyl-3-methylimidazolium cations ([cnmim+]; n = 2, 4, 6 and 8) and bis (trifluoromethylsulfonyl) imide anion ([tf2n]) against e. coli and b. subtilis was measured, for the first time. all ils used in this work were synthesized and analyzed by fourier transform infrared (ft-ir) spectroscopy, nmr, and karl-fischer...
