A lithium-ion conducting gel polymer electrolyte (GPE) membrane containing PEO as a polymer host and liquid electrolyte has been prepared by a simple one-step procedure. The prepared electrolyte membrane exhibits a good ionic conductivity of 3.3 10 3 S cm 1 and high lithium transference number of 0.76 at room temperature. Meanwhile, the gel polymer electrolyte membrane shows very good thermal s...

The adsorbate formed by adsorption of thiophenol on a polycrystalline gold electrode and brought into contact with aqueous solutions of 1 M HClO4 and 0.1 M KClO4 has been studied using cyclic voltammetry and surface-enhanced Raman spectroscopy. A strong adsorption is deduced from observations made using cyclic voltammetry. From the SER spectra, interactions of thiophenol with the gold surface v...

We describe a facile and high-recovery material for rare metals based on a polymer combining amino groups for water solubility and thiourea groups for metal complexation. Good solubility in aqueous metal ion solutions allows for homogeneous and efficient adsorption by the polymer, and a maximum Pd(II) recovery amount (0.508 gPd gpolymer(-1)) greater than those of other polymers reported in the ...

Solid polymer electrolyte system, polyethylene oxide (PEO) complexed with potassium bicarbonate (KHCO3) salt was prepared by solution-cast technique. Several experimental techniques such as infrared radiation (IR), differential scanning calorimeter (DSC), and composition dependence conductivity, temperature dependence conductivity in the temperature range of 308–368 K and transport number measu...

In this work, the eSAFT-VR Mie equation of state (EoS) is extended to low relative permittivity, non-aqueous solutions. The effect using different permittivity relations for electrolyte solutions studied, ranging from experimentally measured values a salt-composition independent permittivity. Furthermore, approaches characteristic diameters in Debye-Hückel and Born terms presented. EoS reparame...

Herein a novel class of solvent systems for cellulose is introduced. Surprisingly, organic electrolyte solutions, which contain just a small molar fraction of ionic liquid, dissolve instantaneously large amounts of cellulose. The solvation properties of the solvent systems, required for dissolving the polymer, are discussed here.

absorptive characteristics of polyaniline synthesized in different solvents were studied. water and mixture of water with other solvents were implemented for polyaniline synthesis. synthesized polyanilines in powder shape is used as an adsorbent to remove toxic hexavalent chromium from aqueous solutions. experiments were conducted in batch mode. removal mechanism involving polyaniline is the co...

Rheological studies were performed with aqueous salt solutions of viscoelastic cationic surfactant erucyl bis(hydroxyethyl)methylammonium chloride (EHAC) and its mixtures with hydrophobically modified polyacrylamide. The solutions of surfactant itself above the concentration of crossover of wormlike micelles exhibit two regions of rheological response. In the first region, they behave like poly...

The thermal stabilities of RNA:DNA hybrids are substantially greater than those of DNA:DNA duplexes in aqueous electrolyte solutions containing high concentrations of formamide. Association rates to form DNA:DNA duplexes and DNA:RNA hybrids have been measured in these solvents. There is a temperature range in which DNA:DNA rates are negligible and RNA:DNA rates close to optimal.
