An experimental attempt was made to analyze structural and ion transport properties in the case of a new mixed system viz., (BiI3)y (Ag2WO4)100-y where y = 10, 20, 30, 40, 50, 60, 70, 80 and 90 mol% respectively. The samples synthesized by the rapid melt-quenching technique were analyzed using Fourier Transform Infrared (FT–IR) spectroscopy, differential scanning calorimetric (DSC) analysis and...

Selective ion transport across membranes is critical to the performance of many electrochemical energy storage devices. While design strategies enabling ion-selective transport are well-established, enhancements in membrane selectivity are made at the expense of ionic conductivity. To design membranes with both high selectivity and high ionic conductivity, there are cues to follow from biologic...

The potential of room-temperature molten salts (ionic liquids) as solvents for electrolytes for dye-sensitized solar cells has been investigated during the last decade. The non-volatility, good solvent properties and high electrochemical stability of ionic liquids make them attractive solvents in contrast to volatile organic solvents. Despite this, the relatively high viscosity of ionic liquids...

The gill of fishes is modified for gas exchange, thereby providing a site for net movement of salts and water down their respective gradients. Specialized cells in the gill epithelium are joined by tight junctions of variable depth and express a variety of transporters and channels. These cells mediate NaCl extrusion in marine fishes and NaCl uptake in freshwater fishes. These transport steps a...

The organic electrochemical transistor (OECT), capable of transducing small ionic fluxes into electronic signals in an aqueous environment, is an ideal device to utilize in bioelectronic applications. Currently, most OECTs are fabricated with commercially available conducting poly(3,4-ethylenedioxythiophene) (PEDOT)-based suspensions and are therefore operated in depletion mode. Here, we presen...

Wurtzite CuInS2 nanoleaves were synthesized by Cu1.94S-assisted growth. By observing the evolution of structures and phases during the growth process, Cu1.94S nanocrystals were found to be formed after uninterrupted oxidation and sulfidation of copper nanoparticles at the early stage, serving as catalysts to introduce the Cu and In species into CuInS2 nanoleaves growth for inherent property of ...

Single channel current-voltage (IV) relations were measured from proteins that form channels across the outer membranes of Gram-negative bacteria – porins and their mutants in solutions of KCl. The wild-type porins and some of their specific mutants have known x-rays structures, which lays the foundation for this theoretical work. The ionic strength of KCl ranges from 100mM to 3M. Using the alr...

The transition behavior and dynamics of ionic transport were strongly influenced by changes in the crystal structure and interaction field of the crystalline ionic gel electrolytes with respect to chemical compositions, as proven by impedance, (7)Li NMR, PCA and 2D IR COS.

A series of ionic liquids containing different paramagnetic anions have been prepared and all show paramagnetic behavior with potential applications for magnetic and electrochromic switching as well as novel magnetic transport; also, the tetraalkylphosphonium-based ionic liquids reveal anomalous magnetic behavior.
