Processing of composite rod with embedded optical fiber
(Kluwer Academic Publ, Dordrecht, 1998)
Heat-treated iron(III) tetramethoxyphenyl porphyrin supported on high-area carbon as an electrocatalyst for oxygen: I. Characterization of the electrocatalyst
(Electrochemical Soc Inc, Pennington, 1998)
Iron(III) tetramethoxyphenyl porphyrin chloride adsorbed on the Black Pearls carbon (FeTMPP-Cl/BP) was heat-treated at temperatures from 200 to 1000°C in Ar atmosphere and characterized by using cyclic voltammetry, X-ray ...
Oxygen reduction on iron. Part VII. Temperature dependence of oxygen reduction on passivated iron in alkaline solutions
(Elsevier Science Sa, Lausanne, 1995)
The temperature dependence of the kinetics of O2 reduction was studied on passivated Fe in NaOH solutions having a concentration ranging from 0.010 to 1.0 mol dm-3 and in the temperature range from 2 to 42 °C. The apparent ...
Dobijanje biološki-aktivnog vlakna sa anestezijskim efektom / Herstellung von biologischaktiven Faser mit anästhetischen Wirkung
(Loznica : Viskoza, 1993)
Biološki aktivna vlakna se uglavnom koriste u medicinske svrhe. Osnovna funkcija im je da doprinesu što povoljnijim rezultatima kod raznovrsnih lekarskih intervencija, kao i u sprovođenju preventivnih mera.

Cathodic processes on corroding low-carbon steel: the effect of the degree of deformation
(Pergamon-Elsevier Science Ltd, Oxford, 1992)
The influence of the degree of deformation of low-carbon steel (0.48% Mn, 0.47% Si, 0.085% C) caused by mono-axial stretching was investigated with respect to the kinetics of electrochemical hydrogen evolution and the ...
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 ...
