Plastic crystallinity of lithium salt, [LiB(OCH(2)CH(2)OCH(3))(4)] (1), and its solid-state ionic conductivity are disclosed. The addition of small amounts of lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) to borate 1 led to the drastic increase of the ionic conductivity and lithium transport number of the electrolyte.

page 124 Abstract: Nanofluidic channels have many uses in the chemical field, including site specific combinatorial synthesis, macroand bio-molecular analysis, and other “lab on a chip” applications. The objective of this research is to fabricate arrays of nanochannels designed to facilitate the transport of aqueous ionic solutions by adapting a form of the nanoimprinting technique. Nanoimprint...

We studied the ionic/electronic transport and resistance degradation behavior of dielectric oxides by solving the electrochemical transport equations. Here, we took into account the non-periodical boundary conditions for the transport equations using the Chebyshev collocation algorithm. A sandwiched NijSrTiO 3 jNi capacitor is considered as an example under the condition of 1.0 V, 1.0 lm thickn...

Ionic transport coefficients for dense plasmas have been numerically computed using an effective Boltzmann approach. We have developed a simplified effective potential approach that yields accurate fits for all of the relevant cross sections and collision integrals. Our results have been validated with molecular-dynamics simulations for self-diffusion, interdiffusion, viscosity, and thermal con...

The skin from four species of North American tree frogs (Hylidae) was found in vitro, to be remarkably permeable to water in the presence or absence of the neurohypophysial hormone vasotocin. This property was, however, only seen in preparations from the ventral integument; osmotic water movement across the dorsal skin was negligible. The ionic permeability, reflected by the electrical resistan...

The description of transport phenomena in biological membranes is still unclear from the viewpoint of physical chemistry. Transport phenomena in ion exchange membranes can be controlled by several factors such as ionic concentration within the membrane, fixed charge concentration, solution composition, ionic fluxes, and water content. The ionic transport as well as distinctive selectivity is pr...

The transport of molecules in confined media is subject to entropic barriers. So theoretically, asymmetry of the confinement length may lead to molecular ratchets with entropy as the only driving force for the biased transport. We address experimentally this question by performing alternative ionic current measurements on electrolytes confined in neutral conical nanopores. In case anions and ca...

Ion transport through nanopores is an important process in nature and has important engineering applications. To date, most studies of nanopore ion transport have been carried out with electrolytes of relatively low concentrations. In this paper, we report on ionic current modulation from the translocation of dsDNA through a nanopore under high ionic strength and with an electrolyte concentrati...
