The intrinsic diffusion coefficients for the two components are found to be in the order of magnitude 10-7 and 10-13~10-14 cm2s-1, respectively, with an apparent value for the slow component in the order of 10-10cm2s-1.展开更多

Equilibrium properties of water-based liquids are well understood via localized atomic and molecular orbital theories. However, the mechanism of electrical conductivity of pure water has proven elusive. We show here it is trapping limited drift of positive and negative quasi-protons (or protons and proton-vacancies) on the extended water lattice, which is accounted for by the long-range correlation inherent in the Fermion (electrons and protons) and Boson (phonons) energy band theory of quasi-particles in solids, with vigorous adherence to equilibrium and nonequilibrium states.展开更多

In this second report, we present the theoretical charge control capacitances of pure and impure water as a function of the DC electric potential applied to water.展开更多
