Dimensional analysis is shown to give an insight into the non-ergodic behaviour of spin ice below its apparent 'spin freezing' temperature. Expressions are derived for the temperature-dependent magnetic susceptibility that are found to be highly consistent with the previously reported field cooled and zero field cooled magnetization of the spin ice dysprosium titanate, Dy(2)Ti(2)O(7), as well a...

The variation of the activity coefficient aqueous sulfuric acid with concentration, solution's temperature, and solvent's (water) dielectric constant, clearly fits a typical strong 1–3 electrolyte behaviour [Fraenkel, J. Phys. Chem. B. 116, 11662 (2012)]. Therefore, was proposed to have molecular formula H4SO5, dissociate 3H+ (3H3O+) 1HSO53?. When above study reported, electric conductivity dat...

The fundamentals of a consistent relativistic approach to determination radiation and spectral characteristics the atomic systems (atoms, multicharged ions in plasmas conditions) strong external electromagnetic field (EMF), which is based on energy formalism (REA) (adiabatic Gell-Mann Low formalism) many-body perturbation theory (RMBPT) for are presented. Within an approximation formula express...

Reliable prediction of freezing point depression in liquid electrolytes will accelerate the development improved Li-ion batteries which can operate low temperature environments. In this work we establish a computational methodology to calculate activity coefficients and liquidus lines for battery-relevant electrolytes. Electronic structure methods are used conjuction with classical molecular dy...

Abstract The electroosmotic flow of non-Newtonian fluid–Eyring fluid in microparallel pipes under high zeta potential driven by the combination pressure and electric force is studied. Without using Debye–Hückel (DH) linear approximation, numerical solutions distribution velocity obtained finite difference method are compared with analytical approximate DH approximation. results show that this a...

Computer simulation by the method of Brownian dynamics is used to study the statistical properties of neutral and charged dendrimers up to the sixth generation (382 groups) in dilute solutions. Excluded-volume interactions are described by the Lennard–Jones repulsive potential corresponding to an athermal solvent. Electrostatic interactions are considered in the Debye–Hückel approximation. The ...

The adsorption of a flexible polyelectrolyte in a salt solution onto an oppositely charged spherical surface is investigated. An analytical solution is derived, which is valid for any sphere radius and consistently recovers the result of a planar surface in the limit of large sphere radii, by substituting the Debye-Hückel potential via the Hulthén potential. Expressions for critical quantities ...

Classical Coulomb systems at equilibrium, bounded by a plane dielectric wall, are studied. A general two-point charge correlation function is considered. Valid for any fixed position of one of the points, a new relation is found between the algebraic tail of the correlation function along the wall and the dipole moment of that function. The relation is tested first in the weak-coupling (Debye-H...
