Diffusion — This article is about the generic concept of the time dependent random process. For other uses, see Diffusion (disambiguation). Diffusion describes the spread of particles through random motion from regions of higher concentration to regions of… … Wikipedia
Diffusion-controlled reaction — Diffusion controlled (or diffusion limited) reactions are reactions that occur so quickly that the reaction rate is the rate of transport of the reactants through the reaction medium (usually a solution).[1] As quickly as the reactants encounter… … Wikipedia
Diffusion MRI — Diagnostics DTI Color Map MeSH D038524 Diffusion MRI is a mag … Wikipedia
Diffusion control — refers to reactions whose rate is governed by transport of the reactants through the reaction medium (usually a solution). The process of chemical reaction can be considered as involving the diffusion of reactants till they encounter each other… … Wikipedia
Diffusion creep — refers to the deformation of crystalline solids by the diffusion of vacancies through their crystal lattice.[1] Diffusion creep results in plastic deformation rather than brittle failure of the material. Diffusion creep is more sensitive to… … Wikipedia
Transport phenomena — In physics, chemistry, biology and engineering, a transport phenomenon is any of various mechanisms by which particles or quantities move from one place to another. The laws which govern transport connect a flux with a motive force . Three common … Wikipedia
Diffusion of innovations — The diffusion of innovations according to Rogers. With successive groups of consumers adopting the new technology (shown in blue), its market share (yellow) will eventually reach the saturation level. In mathematics the S curve is known as the… … Wikipedia
Rate-determining step — The rate determining step (RDS) is a chemistry term for the slowest step in a chemical reaction. The rate determining step is often compared to the neck of a funnel; the rate at which water flows through the funnel is determined by the width of… … Wikipedia
diffusion — 1. The random movement of molecules or ions or small particles in solution or suspension under the influence of brownian (thermal) motion toward a uniform distribution throughout the available volume; the rate is relatively rapid among liquids an … Medical dictionary
Radiative transfer equation and diffusion theory for photon transport in biological tissue — Photon transport in biological tissue can be equivalently modeled numerically with Monte Carlo simulations or analytically by the radiative transfer equation (RTE). However, the RTE is difficult to solve without introducing approximations. A… … Wikipedia
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
