Chronopotent iometry of chromate in the presence of NiC12 in molten LiCIKCI eutectic reveals a diffusion controlled, three electron reduct ion step. In the presence of excess NiC12, chromate is reduced at --0.35V vs. P t ( I I ) / P t reference electrode and the electroactive species responsible for the chronopotentiometric wave is estimated to have a diffusion coefficient of 1.06 9 10 -5 cm 2 ...

Concrete is seldom saturated due to its self-desiccation. Even the submerged concrete structures may remain unsaturated for quite a long time. It has been reported the saturation level of pore solution has significant effect on species penetration. However, very little work was proposed regarding the transport properties and serviceability of concrete structures made of blended cementitious mat...

a new poly(vinylchloride) membrane sensor for cr3+ ions based on di (benzylamino)glyoxime asan ionophore was prepared. the electrode has a linear dynamic range 1×10-6-1×10-1 mol l-1,with anernstian slope of 20.3 ± 0.5 mv per decade and a detection limit of 2×10-7. it has a fast responsetime of

1'HE data in the literature dealing with the permeability of the cornea give variable and dissimilar results both with regard to the irreciprocity of the.permeability and to the magnitude and quality of the necessary osmotic forces and to the rate of diffusion. The purpose of our experiments was to estimate these discrepancies using a different method, and to examine the points brought out abov...

We have developed a united atom (UA) nonpolarizable force field for 1-alkyl-3-methyl-imidazolium chloride ([C(n)mim][Cl], n = 1, 2, 4, 6, 8), a potential solvent for the pretreatment of lignocellulosic biomass. The charges were assigned by fitting the electrostatic potential surface (ESP) of the ion pair dimers. The Lennard-Jones parameters of the hydrogen atoms on the imidazolium ring were adj...

Synaptic transmission is the main process providing cross-connecting activity among neurons in central nervous system (CNS). In present study, 3D mathematical model of a neuronal bouton with cluster localization glycine receptors (GlyRs) on post-synaptic membrane was developed. The number and eventual position are defined by structural data GlyR-gephyrin complex. Furthermore, forming inhibitory...

Description The cystic fibrosis transmembrane regulator (CFTR) gene codes for the CFTR protein; a chloride channel protein that helps in the transportation of chloride ions and water molecules across the cell membranes of lungs, liver, pancreas, and skin. CFTR is a member of the ATP-binding cassette family of membrane transport proteins, but appears to be unique within this family by functionin...
