61Semipermeable membrane — Scheme of semipermeable membrane during hemodialysis, where red is blood, blue is the dialysing fluid, and yellow is the membrane. A semipermeable membrane, also termed a selectively permeable membrane, a partially permeable membrane or a… …
62Membrane technology — The membrane technology covers all process engineering measures for the transport of substances between two fractions with the help of permeable membranes. That means in general mechanical separation process for separation of gaseous or liquid… …
63Glossary of fuel cell terms — The Glossary of fuel cell terms lists the definitions of many terms used within the fuel cell industry. The terms in this glossary may be used by fuel cell industry associations, in education material and fuel cell codes and standards to name but …
64IONS (ÉCHANGEURS D’) — Un échangeur d’ions est un solide comportant des groupements fonctionnels ionisés, fixes, porteurs de charges positives ou négatives et des ions mobiles de signe contraire échangeables avec d’autres provenant d’une solution. Pour accélérer ces… …
65Membrane transport protein — A membrane transport protein (or simply transporter) is a membrane protein[1] involved in the movement of ions, small molecules, or macromolecules, such as another protein across a biological membrane. Transport proteins are integral membrane… …
66law — 1. A principle or rule. 2. A statement of fact detailing a sequence or relation of phenomena that is invariable under given conditions. SEE ALSO: principle, rule, theorem. [A.S. lagu] Alexander l. states that a jerky nystagmus becomes worse when… …
67Scheil equation — In metallurgy, the Scheil Gulliver equation (or Scheil equation) describes solute redistribution during solidification of an alloy. This approach approximates non equilibrium solidification by assuming a local equilibrium of the advancing… …
68Péclet number — 1. measure of the relative contribution of mechanical dispersion and diffusion to solute transport. It relates the effectiveness of mass transport by advection to the ? =? ? ? ?!!! ? ? ? vx D C x P C x e ? ? …
69Column chromatography — A chemist in the 1950s using column chromatography. The Erlenmeyer receptacles are on the floor. Column chromatography in chemistry is a method used to purify individual chemical compounds from mixtures of compounds. It is often used for… …
70Poultice — A poultice, also called cataplasm, is a soft moist mass, often heated and medicated, that is spread on cloth over the skin to treat an aching, inflamed, or painful part of the body. It can also be a porous solid filled with solvent used to remove …
