This is a preview. Log in through your library . Abstract Radical formation in the reactions of hydrogen atoms with some cystinefree proteins and polyalanine was investigated by both ESR and ...

Because ketones are widespread in organic molecules, chemists are eager to develop new reactions that use them to form ...

Haze is formed when a cocktail of various gaseous pollutants is oxidized and forms particulate matter diffusing sunlight. This process is mainly mediated by hydroxyl radicals (OH), and researchers ...

Free radicals are unstable atoms or molecules with free outer electrons. This makes them highly reactive because free electrons always strive to form a stable bond. This stabilization involves gaining ...

Photochemical reactions begin by absorption of energy in the form of light, and involve formation of free radicals and transient excited states whose physical and chemical properties are very ...
