(1) Elemental bromine is made by oxidation , removal of electrons from bromide ions in brine.(2) The drop in pH is probably mainly due to oxidation of upward diffusing sulphide.(3) On ageing, textiles are usually damaged by oxidation or acid-catalysed hydrolysis.(4) In the case of ethanol, oxidation can occur under the action of certain species of bacteria.(5) The silver metal gives up some of its electrons and forms silver sulfide in a process called oxidation .(6) AITiN has a higher aluminum content than the TiAIN coating, which is said to result in a coating with higher hardness that increases hot hardness and the oxidational stability of the coating.(7) Peroxidase and polyphenol oxidase activities were measured as markers of oxidative metabolism.(8) The role of nitric oxide derivatives in oxidative stress and fatigue is controversial.(9) Copper-induced damage can be considered an oxidative stress mediated by activated oxygen species.(10) Free radicals catalyzed by metal can present an oxidative stress to lung tissue.(11) Oxidational wear of tin coatings on tool steel and nitrided tool steel in unlubricated fretting.(12) Antioxidants delay or inhibit this oxidative damage by mopping up the free radicals responsible for autoxidation.
