The zero-length column method was designed to measure this process within zeolite crystals. Its rate is the denominator of the Thiele modulus.  The effective constant for it is a function of its bulk constant along with tortuosity and hindrance factors. Large scale enriching uranium is accomplished using centrifugation or this process.  The mass flux is a function of the partial derivative of concentration with respect to length in Fick's law describing this. Osmosis is this of water across a membrane.  For 10 points, name this phenomenon resulting from the random movement of particles that sees transfer between regions of high concentration to regions of low concentration.
