In atmospheric chemistry, the most common scavenger is the hydroxyl radical, a short-lived radical produced photolytically in the atmosphere. It is the most important oxidant for carbon monoxide, methane and other hydrocarbons, sulfur dioxide, hydrogen sulfide, and most of other contaminants, removing them from the atmosphere.
Oftentimes, scavenger communities differ in consistency due to carcass size and carcass types, as well as by seasonal effects as consequence of differing invertebrate and microbial activity. [4] Competition for carrion results in the inclusion or exclusion of certain scavengers from access to carrion, shaping the scavenger community.
The components of an oxygen absorber vary according to intended use, the water activity of the product being preserved, and other factors. Often the oxygen absorber or scavenger is enclosed in a porous sachet or packet but it can also be part of packaging films and structures. [4] Others are part of a polymer structure. [5]
Scavenger (chemistry), a method of removing impurities or other undesired chemicals from a mixture; Scavenger receptor (endocrinology) Scavenger receptor (immunology), a group of pattern recognition receptors of the innate immune system; Scavenging (engine), automotive process of pushing exhausted gas-charge out of the cylinder and drawing in ...
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Scientific terminology is the part of the language that is used by scientists in the context of their professional activities. While studying nature, scientists often encounter or create new material or immaterial objects and concepts and are compelled to name them.
The name "international scientific vocabulary" was first used by Philip Gove in Webster's Third New International Dictionary (1961). [1] As noted by David Crystal, [2] science is an especially productive field for new coinages.
The scavenger receptor superfamily is defined by its ability to recognize and bind a broad range of common ligands. These ligands include: polyanionic ligands including lipoproteins, apoptotic cells, cholesterol ester, phospholipids, proteoglycans, ferritin, and carbohydrates. [ 4 ]
