Surface area to volume ratio — In chemical reactions involving a solid material, the surface area to volume ratio is an important factor for the reactivity, that is, the rate at which the chemical reaction will proceed. In some industries it is abbreviated sa/vol.Physical… … Wikipedia
Surface area — is the measure of how much exposed area an object has. It is expressed in square units. If an object has flat faces, its surface area can be calculated by adding together the areas of its faces. Even objects with smooth surfaces, such as spheres … Wikipedia
Surface enhanced Raman spectroscopy — Surface Enhanced Raman Spectroscopy, or Surface Enhanced Raman Scattering, often abbreviated SERS, is a surface sensitive technique that results in the enhancement of Raman scattering by molecules adsorbed on rough metal surfaces. The enhancement … Wikipedia
Volume form — In mathematics, a volume form is a nowhere zero differential n form on an n manifold. Every volume form defines a measure on the manifold, and thus a means to calculate volumes in a generalized sense. A manifold has a volume form if and only if… … Wikipedia
surface analysis — ▪ chemistry Introduction in analytical chemistry (chemistry), the study of that part of a solid that is in contact with a gas or a vacuum. When two phases of matter are in contact, they form an interface. The term surface is usually… … Universalium

Surface-conduction electron-emitter display — A surface conduction electron emitter display (SED) is a flat panel display technology that uses surface conduction electron emitters for every individual display pixel. The surface conduction emitter emits electrons that excite a phosphor… … Wikipedia
Volume entropy — Among the various notions of entropy found in dynamical systems, differential geometry, and geometric group theory, an important role is played by the volume entropy.Let (M,g) be a closed surface with a Riemannian metric g . Denote by ( ilde{M},… … Wikipedia
Air permeability specific surface — The air permeability specific surface of a powder material is a single parameter measurement of the fineness of the powder. The specific surface is derived from the resistance to flow of air (or some other gas) through a porous bed of the powder … Wikipedia
Ocean surface wave — Ocean surface waves are surface waves that occur on the free surface of the ocean. They usually result from wind, and are also referred to as wind waves. Some waves can travel thousands of miles before reaching land. They range in size from small … Wikipedia
Bowen ratio — A Bowen ratio is the ratio of energy fluxes from one medium to another by sensible and latent heating respectively. It is calculated by the equation : B = {frac{Q h}{Q e,where Q h is sensible heating and Q e is latent heating. The quantity was… … Wikipedia
