Kinetics of O-2 reduction on a Pt electrode covered with a thin film of solid polymer electrolyte
(Electrochemical Soc Inc, Pennington, 1997)
The kinetics of O-2 reduction on both oxidized and reduced Pt rotating disk surfaces covered with thin films (1 to 15 mu m) of recast polybenzimidazole (PBI) or Nafion have been examined in 0.1 M aqueous solutions of H3PO4, ...
An intensity based optical fibre sensor for flexural damage detection in woven composites
(Sage Publications Ltd, London, 1999)
Flexural deformation of the composite laminate and the integrity of the embedded optical fibres under three-point bending load were monitored. Signal attenuation in optical fibres was used as the damage indicator. The ...
Oxygen reduction on iron-V. Processes in boric acid-borate buffer solutions in the 7.4-9.8 pH range
(Pergamon-Elsevier Science Ltd, Oxford, 1991)
O2 and H2O2 reduction was studied on Puratronic iron (99.995%) in borate buffer solutions of various pH ranging from 7.4 to 9.8. In solutions of pH < 9.3 the E-j curves are of quite irregular shapes and the limiting ...
Pertraction of Solutes in Double Hollow-Fiber Membrane Pertractors, In book: Chemical and Process Engineering-IcheaP-2
(AIDIC Associazione Italiana di Ingegneria Chimica, 1995)
Oxygen reduction on iron-IV. The reduction of hydrogen peroxide as the intermediate in oxygen reduction reaction in alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 1991)
The kinetics of hydrogen peroxide reduction were studied on iron in borate buffered and unbuffered solutions of pH ranging from 8.6 to 13.8, with and without the presence of chloride ions. A rotating disk electrode was ...
Copper Separation from Aqueous Effluents by Liquid Membrane Pertraction
(International Ecological Congress, Voronezh, Russia, September 22-28, 1996)
In this paper the feasibility of applying liquid membrane pertraction to the copper
recovery from aqueous effluents has been examined. A continuos laboratory-scale
hollow fiber-in-fiber type membrane pertractor was ...
Recovery of Indium in a Hollow Fiber Membrane Pertractor
(International Ecological Congress, Voronezh, Russia, September 22-28, 1996)
In the present work, the recovery of indium from sulfate media using a continuos-type membrane
pertractor with hollow fiber geometry was investigated as a study of the feasibility of the industrial
application of this ...
