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...

in this work, a molecular dynamics simulation of the transport of water - methanol mixture through the single wall carbon nanotube (swcnt) is reported. methanol and water are selected as fluid molecules since water represents a strongly polar molecule while methanol is as an intermediate between polar and strongly polar molecules. some physical properties of the methanol-water mixture such as r...

Values of ionic transport numbers and ionic mobilities were determined for the fused system KCl-PbCl2. Cation transport numbers of 0.24 (525°C) and 0.78 (850°C) were found for PbCl2 and KCl, respectively. In each mixture studied tdeviated positively and both t+ and t++ deviated negatively from linearity when plotted against equivalent fraction. The initial very rapid depression of total equival...

Solar cells based on organic-inorganic halide perovskites have recently shown rapidly rising power conversion efficiencies, but exhibit unusual behaviour such as current-voltage hysteresis and a low-frequency giant dielectric response. Ionic transport has been suggested to be an important factor contributing to these effects; however, the chemical origin of this transport and the mobile species...

Understanding the mechanisms of lithium-ion transport in polymers is crucial for the design of polymer electrolytes. We combine modular synthesis, electrochemical characterization, and molecular simulation to investigate lithium-ion transport in a new family of polyester-based polymers and in poly(ethylene oxide) (PEO). Theoretical predictions of glass-transition temperatures and ionic conducti...

Non-linear ion transport through nanoscale structures can be used in new types of microcircuit, inspired by biological processes such as adenosine triphosphate synthesis and neural transmission. The non-linear current resulting from preferential direction of ion flow can be used for signal transmission as well as signal processing, for example, ionic current rectification and amplification as i...

A theoretical analysis is presented that allows in situ measurements of the physical properties of a composite electrode, namely, the electronic conductivity, the ionic conductivity, the exchange-current density, and the double-layer capacitance. Use is made of the current-voltage responses of the composite electrode to dc and ac polarizations under three different experimental configurations. ...

The transport of polystyrene microspheres was examined in packed glass beads under a variety of environmentally relevant ionic strength and flow conditions. The observed profiles of numbers of retained microspheres versus distance from the column entrance were much steeper than expected based on a constant rate coefficient of deposition acrossthe length of the column, indicating apparent decrea...

In this study, ion exchange nanocomposite membranes was prepared by addition of Mg(OH)2 nanoparticles to a blend containing sulfonated polyphenylene oxide and sulfonated polyvinylchloride via a simple casting method. Magnesium hydroxide nanoparticles were synthesized via a facile sono-chemical reaction and were selected as filler additive in fabrication of ion exchange nanocomposite membranes. ...

The transport coefficients of three ionic liquids, lithium bromide ~LiBr!, rubidium bromide ~RbBr!, and molten silica (SiO2) are calculated by the mixture mode-coupling theory. The static partial structure factors required are obtained from the interionic interaction potential by the Ornstein– Zernike/hypernetted-chain integral equation. The anomalous pressure dependence of the transport proper...
