This book reviews new information in chemical and biochemical physics, including research on polymers in polluted atmospheres, free radical and ion-radical conversions initiated by nitrogen oxides, selective catalytic oxidation of hydrocarbons, the mechanism of the ethylbenzene oxidation with dioxygen, catalysed by cobalt complexes, measurements of the total phenol type antioxidant content in berry, fruit and vegetable juice mixes, as well as some applications of nanocarbon materials for novel devices, functionalisation of some oligomers in the presence of different catalytic systems and others.
