Chemical composition and phase structure of Zn-Ni alloys obtained by electrochemical deposition under various conditions were investigated. The alloys were deposited on a rotating disc electrode and steel panel from chloride ...
The kinetics of the reactions of 2-substituted nicotinic acids with diazodiphenylmethane in various alcohols / Kinetika reakcija 2-supstituisanih nikotinskih kiselina sa diazodifenilmetanom u različitim alkoholima
(Serbian Chemical Society, Belgrade, 2003)
The rate constants of 2-substituted nicotinic acids in reaction with diazodiphenylmethane (DDM) in eight alcohols at 30 ºC have been determined. In order to explain the obtained results through solvent effects, the second ...
Micromechanical and structural properties of nickel coatings electrodeposited on two different substrates / Mikromehanička i strukturna svojstva elektrodeponovanih prevlaka nikla na različitim supstratima
(Serbian Chemical Society, Belgrade, 2009)
Fine-structured nickel coatings were electrodeposited from a sulfamate-based electrolyte onto different substrates: polycrystalline cold-rolled copper and single crystal silicon with (111) orientation. The influence of the ...
Electrophoretic deposition and thermal treatment of boehmite coatings on titanium / Elektroforetsko taloženje i sinterovanje prevlaka bemita na titanu
(Serbian Chemical Society, Belgrade, 2007)
An aqueous boehmite sol was prepared by the peptization of Al(OH)3. The electrophoretic deposition of boehmite coatings on titanium from the aqueous sol was performed at a constant voltage (from 1.0 to 10 V) and for a ...
