solute diffusion
71Taylor dispersion — is an effect in fluid mechanics in which a shear flow can increase the effective diffusivity of a species. Essentially, the shear acts to smear out the concentration distribution in the direction of the flow, enhancing the rate at which it… …
72coefficient — 1. The expression of the amount or degree of any quality possessed by a substance, or of the degree of physical or chemical change normally occurring in that substance under stated conditions. 2. The ratio or factor that relates a quantity… …
73Grain boundary — A grain boundary is the interface between two grains in a polycrystalline material. Grain boundaries disrupt the motion of dislocations through a material, so reducing crystallite size is a common way to improve strength, as described by the Hall …
74crystal — crystallike, adj. /kris tl/, n., adj., v., crystaled, crystaling or (esp. Brit.) crystalled, crystalling. n. 1. a clear, transparent mineral or glass resembling ice. 2. the transparent form of crystallized quartz. 3. Chem., Mineral. a solid body… …
75Crystal — /kris tl/, n. 1. a city in SE Minnesota, near Minneapolis. 25,543. 2. a female given name. * * * I Any solid material whose atoms are arranged in a definite pattern and whose surface regularity reflects its internal symmetry. Each of a crystal s… …
76Chemical potential — Chemical potential, symbolized by μ, is a measure first described by the American engineer, chemist and mathematical physicist Josiah Willard Gibbs. It is the potential that a substance has to produce in order to alter a system.[1] In broadest… …
77Electrochemical gradient — An electrochemical gradient is a spatial variation of both electrical potential and chemical concentration across a membrane; that is, a combination of the membrane potential (delta psi) and the pH gradient (delta pH). Both components are often… …
78Solution (chimie) — Pour les articles homonymes, voir Solution. Une solution est un mélange homogène de deux ou plusieurs substances, initialement dans un état (solide, liquide, gazeux). La substance majoritaire est appelée solvant, les substances minoritaires sont… …
79Xylem — Multiple cross sections of a flowering plant stem showing primary and secondary xylem and phloem[1] Xylem is one of the two types of transport tissue in vascular plants. (Phloem is the other). The word xylem is derived from the Classical Greek… …
