Diffusion Coefficient: Gas, Liquids, Solids

This lecture covers the diffusion coefficient in gases, liquids, and solids, including the Matano method and the atomic theory of diffusion. It explores Fick equations, Nernst-Einstein equation, and transport forces, as well as cubic and non-cubic structures, simple and interstitial mechanisms, and the influence of temperature and pressure. The lecture delves into chemical diffusion, diffusion in ionic crystals, and the diffusion of electrolytes in liquids. It also discusses self-diffusion in metals, dissemination mechanisms, and diffusion in compound alloys.
