we performed molecular dynamics simulations using the coarse-grained model to study the freezing behavior of pure water and 14% water-salt mixture in a wide range of temperatures for a very long time around 50 nanoseconds. for the salty water, an interface in nanoscale was used. for both systems, the freezing behavior of water molecules was studied using some qualities such as density, total en...
In a paper from this laboratory, describing the dependence of the solubility of the plasma proteins in concentrated salt solutions on the salt and plasma concentrations (l), we pointed out the advantage of using potassium phosphate as a precipitating salt inasmuch as the salt concentration and pH of such solutions could be varied independently as described by Cohn (2). For the specific purpose ...

We propose a simple theoretical formula for describing the refractive indices in binary liquid mixtures containing salt ions. Our theory is based on the Clausius-Mossotti equation; it gives the refractive index of the mixture in terms of the refractive indices of the pure liquids and the polarizability of the ionic species, by properly accounting for the volume change upon mixing. The theoretic...
The electrostatics of micellar growth is reviewed and extended for solutions containing excess salt. In dilute solution the expansion of a linear micelle with increasing salt concentration is explained for a wide range of ionic strength. When the micellar charge density is very high, counterions condense nonuniformly onto the micellar rod. In that case the micelle may contract upon the addition...
An iodide ion-selective PVC membrane sensor based on copper (Π)-bis-Nphenilsalicyldenaminatocomplex as a novel sensing material is successfully developed. Theelectrode showed a good selectivity for iodide ion with respect to common inorganic anions. Thesensor exhibited a good linear response with slope of _58.6 ± 0.4 mV per decade over theconcentration range of 5.0 × 10-6 to 1.0 × 10-1 mol L-1,...
