We reported a composite electrolyte prepared by incorporating layered α-titanium phosphate (α-TiP) into an iodide-based electrolyte using 1-ethyl-3-methylimidazolium tetrafluoroborate(EmimBF4) ionic liquid as solvent. The obtained composite electrolyte exhibited excellent electrochemical and photovoltaic properties compared to pure ionic liquid electrolyte. Both the diffusion coefficient of tri...

1. The interaction of 1-anilinonaphthalene-8-sulphonate with ox liver glutamate dehydrogenase was examined. 2. The fluorescence of the dye is enhanced 100-fold on binding. 3. A further enhancement is observed when NADH and GTP are added to the enzyme. 4. By using this property of the dye to measure conformational equilibria in the enzyme the effects of coenzyme, inhibitors, enzyme concentration...

The degradation of the AB1 dye by electro-generated species using a BDD electrode was performed. The results were explained by the generation of OH radical, S2O8 in the presence of sulfate, and active halide species in the presence of halide salt. The discoloration rate increases in this order: sulfate, KCl, KBr. In the presence of KCl, the discoloration is affected by the current density, init...

The electrolytic conductivities for C.I. Acid Orange 15 and C.I. Acid Red 97 have been studied. The electrolytic conductivities have been analyzed by Deby HUckel-Onsager theory, The degree of ionization, α, Van’t Hoffs factor, i, and thickness of ionic atmosphere, X –1 . were calculated. Each value diminishes with increasing dye concentration. The dye anion transport number, t, mobility’s, μ we...

Calcium-binding stoichiometry, dissociation equilibrium constants at zero ionic strength @Lo), and molar extinction difference coefficients (At,) at the wavelength )r of the metallochromic indicators arsenazo I (ArsI) and tetramethylmurexide (TMX) were reevaluated with a computerized method based on mass conservation and thermodynamic consistency checks. This new method is shown to provide a mo...

A rapid fluorescence imaging system was developed and utilised to investigate the time-course of intracellular calcium concentration ([Ca]i) gradients generated by action potentials in CA1-CA3 pyramidal cells within brain slices of the rat hippocampus. The system, which is based on a fast commercial CCD camera, can acquire hundreds of 128×128 pixel images in sequence, with minimal inter-frame i...

the reduction capacity of ammonia while present even at ppm level can be demonstrated by the increased encounter probability between ammonia and methylene blue dye (mb+) incorporated in nanomordenite and na-mor zeolites. the rate of reduction methylene blue dye by ammonia on the surface nanomordenite zeolite is faster than na-mordenite (na-mor) zeolite.because nanomordenite zeolite with high si...

When striated muscle cells of the jellyfish Polyorchis penicillatus were dissociated at 30 degrees C they retained their in vivo morphology and the integrity of ionic currents. This contrasted with cells dissociated at room temperature that rarely expressed any inward currents. Whole-cell, patch-clamp recordings from dissociated muscle cells revealed that the inward component of the total ionic...

Novel polymer gel electrolytes have been prepared by incorporating LiI-I(2) solutions into a polyethylene oxide matrix supported by a TiO(2) filler. The gel electrolytes, based on either acetonitrile or propylene carbonate solvents are compared with liquid standard ones and are examined by (7)Li solid state nuclear magnetic resonance relaxometry and diffusion measurements. In parallel, the trii...
