Adsorption — is a process that occurs when a gas or liquid solute accumulates on the surface of a solid or a liquid (adsorbent), forming a film of molecules or atoms (the adsorbate). It is different from absorption, in which a substance diffuses into a liquid … Wikipedia

Molecular clusters — Atomic and molecular clusters are aggregates of 5 105 atomic or molecular units. They classify according to the forces holding them together: Van der Waals clusters attraction between induced electric dipoles and repulsion between electron cores… … Wikipedia
Molecular imprinted polymer — A Molecularly Imprinted Polymer (MIP), or plastic antibody is a polymer that is formed in the presence of a molecule that is extracted afterwards, thus leaving complementary cavities behind. These polymers show a certain chemical affinity for the … Wikipedia
adsorption — When a thin layer of a substance adheres strongly to another, holding to it on a molecular level as if it were glued to it. This situation is more likely to occur with substances in a gelatinous state and with the receiving surface absolutely… … Glossary of Art Terms
Vacuum swing adsorption — Vacuum Swing Absorption (VSA) is a non cryogenic gas separation technology. Using special solids, or absorbents, VSA segregates certain gases from a gaseous mixture under minimal pressure according to the species molecular characteristics and… … Wikipedia
DNA separation by silica adsorption — is an important method of DNA separation that is used in novel technologies that use micro channels. The principle behind this type of separation relies on DNA molecules binding to silica surfaces in the presence of certain salts and under… … Wikipedia
Pressure swing adsorption — (PSA) is a technology used to separate some gas species from a mixture of gases under pressure according to the species molecular characteristics and affinity for an adsorbent material. It operates at near ambient temperatures and so differs from … Wikipedia
Catalyst for pressure swing adsorption — Pressure Swing Adsorption (PSA) processes rely on the fact that under pressure gases tend to be attracted to solid surfaces, or adsorbed. The higher the pressure, the more gas is adsorbed; when the pressure is reduced, the gas is released, or… … Wikipedia
