OXIDATION–REDUCTION POLYMERS: III. STANDARD OXIDATION POTENTIALS OF 2,5-DIHYDROXYDIPHENYL SULPHONES

Radiation-induced Oxidation of Polymers

A polymer is a macromolecule formed by the combination of simple molecules, monomers, of low molecular weight. A polymer molecule usually has at least 2000 atoms linked by covalent bonds. In general, polymers can be divided into inorganic and organic, and also into naturally occurring and synthetically produced. Polymers may contain additives such as dyes, fi llers, antioxidants, fl ame retarda...

Oxidation-Reduction Potentials

In the first part of the book purely physico-chemical considerations of redox potentials are lucidly and thoroughly dealt with, and in the second part their applications to physiology are systematically developed. To a student of physiology, who is not well versed in the principles of electrochemistry, this book will be of great value as the author initiates the reader first into those parts of...

Oxidation - Reduction Potentials of the Cytochrome

There have been many investigations of the oxidation-reduction potential of the cytochrome c system. Some of the results are concordant, though none at the time this work was undertaken included a complete potentiometric titration of the system over a range of pH values. Potentials have been reported for the system at varying pH values, usually within a narrow range bordering on the physiologic...

Xcvii. Oxidation-reduction Potentials of Haemolytic Streptococci

PEROXIDE formation has a marked effect on the electrode potential behaviour of bacterial cultures and it has been shown in previous communications that the course of development of reducing and oxidising conditions in cultures of the peroxide-forming organisms haemolytic streptococci [Hewitt, 1930, 1] and pneumococci [1930, 4] differs characteristically from that in cultures of the catalase-con...
