Preliminary organic geochemical investigation of Upper-Jurassic dolomites of Plješvica (Yugoslavia)
(Elsevier, 1984)
The amounts and compositions of the total and soluble organic matter were determined in 17 samples of Upper Jurassic dolomites from the slopes of the mountain Plješivica (Lika, Yugoslavia; locations Vrelo-Mrsinj Grad, ...
Anodic deposition of colloidal gold
(Elsevier, 1984)
Colloidal gold solutions were prepared following classical recipes. When electrolysed between graphite electrodes, gold was found to deposit at the anode. The rate of deposition was dependent on the anode potential, on the ...
Multistage alkaline permanganate degradation of a type II kerogen
(Elsevier, 1984)
The products of a 27-step alkaline permanganate degradation of a type II kerogen from a sample of Toarcian shale, Paris Basin, have been studied. The high yield of oxidation products consisted of 1.86% neutrals and bases, ...
Lanthanum-molybdenum coating for hydrogen evolution on titanium
(Switzerland : Springer Nature, 1984)
There is practical interest in the use of titanium as a cathode material in brine electrolysis processes. The overvoltage of hydrogen evolution on titanium is, however, very high and, at the same time, hydrogen penetrates ...
The evolution of hydrogen on cobalt-molybdenum coating: polarization characteristics
(Switzerland : Springer Nature, 1984)
It is shown that good quality deposits of cobalt-molybdenum alloys may be produced using pulse plating and it is demonstrated that such coatings on titanium have a low overpotential for hydrogen evolution under typical ...
Electrocatalytic optimization of faradaic yields in the chlorate cell process
(Elsevier, 1984)
It has been shown that while the mixed RuO2TiO2 coated titanium anode deteriorates very quickly in the presence of ionic phosphate species, the electrode containing palladium and tin oxides in the coating mixture as well ...
Two-dimensional electrocrystallization of thallium oxide on the single crystal gold surfaces
(Elsevier, 1984)
The electrocrystallization of thin anodic films on metal electrodes continues
provoke interest since the original work of Bewick et al. [1]. These
studies have been focused on the film formation on mercury [1--3] ...
Structural effects in electrocatalysis. Oxygen reduction on the Au (100) single crystal electrode
(Elsevier, 1984)
The kinetics of O2 reduction on the Au (100) single crystal electrode have been examined in alkaline electrolytes using the rotating dise method. A comparison has been made with the Au (110) and Au (111) surfaces. The ...
Fundamental aspects of pulsating current metal electrodeposition VIII: The effect of pause-to-pulse ratio on microthrowing power of metal deposition
(Elsevier, 1984)
The effect of a pulsating current on the microthrowing power of metal deposits in the early stage of deposition was investigated by scanning electron microscopy. It is shown that at the same average current density the ...
Fundamental aspects of pulsating current metal electrodeposition IX: The prevention of spongy deposit formation on inert substrates
(Elsevier, 1984)
It is shown that spongy deposits are obtained under d.c. conditions and that compact deposits are obtained in pulsating current (PC) deposition with high pause-to-pulse ratios at the same average current density and ...
