The higher conversion of residual vinyl monomer and pendant double bonds built up in the Michael network was achieved by a photo-initiated free radical polymerization in the second step of polymer network synthesis. The lifetime of trapped radicals was estimated by following the decay of radicals ...
The results of a 22-week study of pyrolysis liquid properties during storage at various conditions confirm that free radicals are important in the chemical reactions that cause property changes. Past research suggested that oxidation of liquid fuels involves free radical mechanisms (e.g., via ...

ESR Study of Free Radical Decomposition of N,N-Bis(arylsulfonyl)hydroxylamines in Organic Solution The formation of p-tolylsulfonyl radicals has been proved by spin trapping using 2-methyl-2-nitrosopropane (MNP) and 5,5-dimethyl-1-pyrroline N-oxide... MY Balakirev,VV Khramtsov - 《Journal...
The most stable free-radical N 9 cluster is structure 1 with C 2 v symmetry and that of anion N 9 is structure 3 with C s symmetry. Only one stable structure of the N + 9 cation with C 2 v symmetry was predicted. Their potential application as high-energy-density materials has been...

Carotenoids are natural products having a broad spectrum of biological applications, such as, anti-cancer, anti-oxidants, anti-inflammatory and anti-ageing etc. Chemically, they contain long chains of carbon atoms having conjugation and these conjugated
PURPOSE: To obtain a variant Escherichia colli ribonuclease H retained in original enzymatic activity and improved in stability by replacing 95th lysine of natural type Escherichia colli ribonuclease H with glycine. ;CONSTITUTION: 95th lysine of natural type Escherichia colli ribonuclease H is replaced ...
