EARLIER, Ingalls and Wall 1,2 reported the use of electron-spin resonance spectroscopy to investigate the reactions of hydrogen and other gaseous free radicals with polymers in a finely divided fluff ...

THE spatial distribution of free radicals produced by irradiation is of interest in radiation chemistry and radiation biology. Although there have been many theoretical treatments of this problem, ...

These compounds can readily aggregate, increasing the viscosity of the oil, which can plug wellbores and flowlines during the extraction and processing. In addition, asphaltenes can also deactivate ...
