The bonding character of liquid lead telluride \text{PbTe} is thermodynamically investigated in detail. Its possibility as an ionic melt composed of cation {\text{Pb}}^{2+} and anion {\text{Te}}^{2-} is not acceptable, by comparing the ionization ene

The former analysis of the structural data in liquid Pb–Te alloys, based on the neutron diffraction measurements for this system, was insufficient to obtain the microscopic and spatial configurations in this system. In order to obtain these configu

Ray-summation (raysum) images reconstructed from computed tomography (CT) volume data resemble digital radiography (DR) images. Therefore, they have a potential to be used instead of DR images.The aim of this study was to compare the physical image q

The electrical conductivity in aqueous solutions of electrolytes has been obtained in terms of inter-particle potentials and pair distribution functions, based on a generalized Langevin equation for the cation and anion. This treatment allows us to c

A microscopic description for the partial DC conductivities in molten salts developed by the present authors is briefly summarised, starting from the Langevin equation for the constituent ions. It is clarified that the memory function should be writt

The theory of the pre-melting phenomena in ionic crystals on the basis of the concept of the hetero phase fluctuation has been applied to KCl and AgCl crystal. The large scale molecular dynamics simulations (MD) in KCl and AgCl crystals are also perf

The inverse dielectric function 1/ɛ(q) is newly obtained in terms of the charge–charge correlation functions SZZ(q) by the re-examined theory of dielectric screening in molten salts. The new theory is applied to the molten noble-metal halides, i.e

The electrical conductivity of non-equivalent molten salts has been theoretically investigated based on the linear response theory, which is an extension from the expression for equivalent molten salts as we have developed in the previous papers. The

Regarding the ionic conductivities, Sundheim proposed the “universal golden rule” by experiments, i.e. the ratio of the partial ionic conductivities in molten binary salt is equal to the inverse mass ratio of the ions, σ + / σ − = m − / m +
