In mechanochemical devulcanization of GSBR in the presence of TESPT, homolytic cleavage of S~S bond of TESPT occurs which in turn produces fragmented devulcanizing agent (FDA) free radical as temperature rises due to mechanical shearing.
The homolytic scission of the endoperoxide bond followed by the immediate formation of an [[S.
Among homo and heterolytic fermentation, homolytic fermentation is considered more desirable because of high recovery of dry matter and energy.
In other conditions free radicals may forms, for example, homolytic cleavage of either an OH bond or the OO bond in hydrogen peroxide give rise to H + OOH and 2 OH which is hydroxyl radical.
The great benefit of using this plasma technique, especially non-thermal glow-discharge plasma, which is the type of plasma for the present work, is that only the topmost polymeric stratum of material is modified, causing homolytic bond fission and generating free radicals on the polymer surface by abstracting hydrogen free radicals (1) while maintaining the bulk properties intact.
The reaction path occurs presumably through homolytic cleavage of benzoyl peroxide to form two benzoyloxy radicals, which further decompose to carbon dioxide and aryl radical [20, 21] (Figure 1).
Free radical can be formed in three ways: (1) By Homolytic Fission: Radicals can easily be formed when a covalent bond is broken if one electron from each of the pair shared remains with each atom.
29), (34), (36) This high energy of the siloxane bond gives rise to its strong resistance to homolytic cleavage.
The hydroxyl radical is formed in vivo by high energy irradiation leading to homolytic cleavage of water or from [H.
The light-induced homolytic nitrogen-oxygen bond cleavage of N-methoxy nitrogen onium salts produces two transient species, each of which has been shown to damage DNA.
