1928Michaelis & Flexner in Jrnl. Biol. Chem. LXXIX. 689 The success met on application of the theoretical fundamentals of oxidation-reduction potentials (hereinafter to be referred to by us as ‘redox’ potentials)..to organic redox systems..has given great impetus to more elaborate study of physiological materials. 1938Nature 15 Oct. 723/1 Increasing use of redox indicators is being made with marked success in analytical chemistry. 1940Glastone Text-bk. Physical Chem. xii. 932 A reversible oxidation-reduction electrode..sometimes abbreviated to..‘redox’ electrode. 1959Engineering 2 Jan. 25/2 A mercaptan modifier and redox catalyst are employed to obtain the desired molecular structure in the shortest possible reaction time. 1965Phillips & Williams Inorg. Chem. ix. 312 Since galvanic cells consist essentially of two redox couples opposed one against the other, it is convenient to choose one couple arbitrarily and regard it as having zero potential. 1970Ambrose & Easty Cell Biol. ii. 66 Note..that a favourable redox potential does not necessarily mean that a particular reaction will take place, but simply that it is thermodynamically feasible. 1971Nature 4 June 311/2 An internal redox apparently occurs, and the electron moves from cation to anion. Ibid. 12 Nov. 89/1 The red colour of Mars suggests the presence of ferric iron which is not readily explained by the redox state implied by the second hypothesis. 1978P. W. Atkins Physical Chem. xii. 362 In a redox titration a reduced form of an ion (e.g., Fe2+) is oxidized by the addition of some oxidizer (e.g., Ce4+). |
