Diffusion and Kinetics

Topics in the Diffusion part include: diffusion mechanisms, steady-state and non-steady-state diffusion, Fick's first and second laws, Kirkendall effect, short-circuit diffusions, diffusion in metallic, polymeric, ionic and semiconducting materials, Darken's first and second equations, marker's velocity, thin film diffusion. Topics in the Kinetics part include: experimental rate laws, reaction orders, determination of order of reaction (integral, differential, and half-life methods), Arrhenius equation, elucidation of mechanism, fluid-particle reactions, kinetic models (progressive-conversion, unreacted core, shrinking core model), reactor design (batch, plug flow, and mixed flow reactors).
