**Molecular diffusion** — This article is about spontaneous dispersion of mass. For a more generic treatment of diffusion, see Diffusion. Diffusion from a microscopic and macroscopic point of view. Initially, there are solute molecules on the left side of a barrier… … Wikipedia

**Surface diffusion** — [ adatom diffusing across a square surface lattice. Note the frequency of vibration of the adatom is greater than the jump rate to nearby sites. Also, the model displays examples of both nearest neighbor jumps (straight) and next nearest neighbor … Wikipedia

**Fick's laws of diffusion** — For the technique of measuring cardiac output, see Fick principle. Molecular diffusion from a microscopic and macroscopic point of view. Initially, there are solute molecules on the left side of a barrier (purple line) and none on the right. The… … Wikipedia

**Fick's law of diffusion** — Fick s laws of diffusion describe diffusion and can be used to solve for the diffusion coefficient D . They were derived by Adolf Fick in the year 1855. First law Fick s first law relates the diffusive flux to the concentration field, by… … Wikipedia

**Stefan flow** — Stefan flow, occasionally called Stefan s flow (Slovene Stefanov tok ), is a transport phenomena concerning the movement of a chemical species by a flowing fluid (typically in the gas phase) that is induced to flow by the production or removal of … Wikipedia

**Mixing (physics)** — In physics, a dynamical system is said to be mixing if the phase space of the system becomes strongly intertwined, according to at least one of several mathematical definitions. For example, a measure preserving transformation T is said to be… … Wikipedia

**concentration gradient** — The change in solute concentration per unit distance in solute. Concentration gradients cause Fickian diffusion (spreading) of solutes from regions of highest to regions of lowest concentrations. In slowing moving ground water, this is the… … Lexicon of Cave and Karst Terminology

**Amorphous computing** — refers to computational systems that use very large numbers of identical, parallel processors each having limited computational ability and local interactions. The term Amorphous Computing was coined at MIT in 1996 in a paper entitled [http://www … Wikipedia
