Proton-hydroxide permeability of liposomes.
Liposome permeability to net proton-hydroxide flux was compared under two conditions that have produced extreme values in previous studies. In the first [Nichols, J.W. & Deamer, D.W. (1980) Proc. Natl. Acad. Sci. USA 77, 2038-2042] small pH gradients were permitted to decay near pH 7 and permeability coefficients in the range of 10(-4) cm/sec were obtained. In the second [Nozaki, Y. & Tanford, ...
متن کاملProton Diffusion in Nickel Hydroxide Films
Electrochemical impedance spectroscopy (EIS) was used to measure the solid-state diffusion coefficient of protons in nickel hydroxide films at room temperature as a function of state of charge (SOC). A model for the complex faradaic impedance of the nickel hydroxide active material is presented and used to extract the diffusion coefficient of protons from the EIS data. Impedance data over a ran...
متن کاملCombine flake like magnesium hydroxide and cubic like aluminum hydroxide nanostructures in order to improve fire retardant of PVC and PMMA
In this study, Flake-like magnesium hydroxide (Mg(OH)2) and cubic-like aluminum hydroxide (Al(OH)3) nanostructures were synthesized via a simple co-precipitation method at relatively low temperature. Chemical properties and surface morphology of the magnesium hydroxide and aluminum hydroxide were characterized by X-ray diffraction analysis (XRD), scanning electron microscopy image (SEM), transm...
متن کاملComparison of apexification with mineral trioxide aggregate and calcium hydroxide.
PURPOSE The aim of this study was to compare mineral trioxide aggregate (MTA) with calcium hydroxide [Ca(OH)2] clinically and radiographically as materials used to induce root-end closure in necrotic permanent teeth with immature apices (apexification). METHODS Fifteen children, each with at least 2 necrotic permanent teeth requiring root-end closure (apexification), were selected for this st...
متن کاملStructures, energetics, and spectra of hydrated hydroxide anion clusters.
The structures, energetics, electronic properties, and spectra of hydrated hydroxide anions are studied using density functional and high level ab initio calculations. The overall structures and binding energies are similar to the hydrated anion clusters, in particular, to the hydrated fluoride anion clusters except for the tetrahydrated clusters and hexahydrated clusters. In tetrahydrated syst...
