linear energy transfer (biology)
Science; General science
A physical factor which is significant in biology because, in many biological actions of high-energy radiations, linear energy transfer (LET) strongly and characteristically ...
chromatography
Science; General science
A physical method of separation in which the components of a mixture of substances are separated from each other by differences in their distribution between two phases, one ...
stochastic process
Science; General science
A physical stochastic process is any process governed by probabilistic laws. Examples are (1) development of a population as controlled by mendelian genetics; (2) brownian motion ...
ion implantation
Science; General science
A process that utilizes accelerated ions to penetrate a solid surface. The implanted ions can be used to modify the surface composition, structure, or property of the solid ...
cracking
Science; General science
A process used in the petroleum industry to reduce the molecular weight of hydrocarbons by breaking molecular bonds. Cracking is carried out by thermal, catalytic, or ...
chemical separation (chemical engineering)
Science; General science
A process used to purify substances or to isolate them from other substances. In industrial applications, the ultimate goal is the isolation of a product of given purity. Most ...
flotation
Science; General science
A process used to separate particulate solids, which have been suspended in a fluid, by selectively attaching the particles to be removed to a light fluid and allowing this ...
