A general formalism to study the dynamics of polyelectrolyte solutions is presented. We show in particular that the Berne-Pecora equations for charged pointlike particles are obtained by neglecting the memory function and using the Debye-Huckel potential with the linear approximation exp( U /kB T)-===1 U /kB T. We generalize Berne-Pecora results by introducing the effect of hydrodynamic interac...

We deduce that charged liquid droplets minimizing Debye-Huckel-type free energy are spherical in the small charge regime. The variational model was proposed by Muratov and Novaga 2016 to avoid ill-posedness of classical one. By combining a recent (partial) regularity result with Selection Principle Cicalese Leonardi, we prove ball is unique minimizer

BACKGROUND Normal cell function requires timely and accurate transmission of information from receptors on the cell membrane (CM) to the nucleus. Movement of messenger proteins in the cytoplasm is thought to be dependent on random walk. However, Brownian motion will disperse messenger proteins throughout the cytosol resulting in slow and highly variable transit times. We propose that a critical...

The protonation of different species of glycylisoleucine were studied in the pH range of 1.5 - 10 at25 °C using potentiometric technique. Investigations were performed in sodium perchlorate andtetraethylammonium iodide as background electrolytes at I (0.1, 0.2, 0.3, 0.4, 0.5, and 0.6) moldm-3. The parameters based on the protonation constants were calculated, and their dependenceson ionic stren...

Neutrinos in core collapse supernovae are likely trapped by neutrino-nucleus elastic scattering. Using molecular dynamics simulations, we calculate neutrino mean free paths and ion-ion correlation functions for heterogeneous plasmas. Mean free paths are systematically shorter in plasmas containing a mixture of ions compared to a plasma composed of a single ion species. This is because neutrinos...

The prtnonation constant values of tryptophan were studied at 25 C. different ionic strengths. 0.1-1.0 moldm", and various ionic media of NaCIO, and N4N01, using a combination of spectrophotometrie andpotentiometric techniques. The general vend for the two protonation con Slant Vai net of tryptophan is in theorder of NaC104 > NaNO3 in different ionic media. The dependence of protonation constan...

The regular Einstein relation, connecting the coefficient of ambipolar diffusion and the Dember field with mobilities, is generalized for the case of an interacting electron-hole plasma. The calculations are presented for a nondegenerate plasma injected by light into semiconductors of silicon and germanium type. The Debye-Huckel correlation and the Wigner-Seitz exchange terms are considered. Co...

Due to intermolecular interactions, the surface composition of mixed self-assembled monolayers often differs markedly from the solution composition. In the case of charged surfactants, large deviations from the ideality have been reported. The effect of the electrostatic interactions between charged compounds on the surface composition is examined using a simple gas lattice model, in the Bragg-...

The electric field of dissolved ions accounts for the narrow spike at zero frequency shift, with the polarization signature of a polar longitudinal collective mode, in the high resolution hyper-Rayleigh light scattering (HRS) spectrum for liquid water and other polar solvents. This peak in the HRS spectrum probes both the structure factor and the fluctuation time for the ion charge density in s...
