Electrochemically deposited Ni+WC composite coatings obtained under constant and pulsating current regimes
(Netherlands : Kluwer Academic Publishers, 2004)
A series of Ni+WC composite coatings were obtained by electrodeposition on a rotating disc electrode (RDE)from a commercially available Watts bath containing additives for brightness and smoothing and insoluble WCparticles, ...
Reflection and structural analyses of mirror-bright metal coatings
(Springer, 2004)
Reflection and structural analyses of different copper and zinc coatings were performed. The copper coatings were electrodeposited from a sulfate solution in the presence of thiourea, as well as in the presence of modified ...
The influence of oxide sol properties on the capacitive behavior of carbon supported hydrous ruthenium oxide
(Progress in Advanced Materials and Processes: Proceedings of the Fifth Jugoslav Materials Research Society, YUCOMAT V, 2004)
Carbon supported hydrous ruthenium oxide was prepared by ail ultrasonic threatment of carbon black-RuOxHy sol mixture (impregnation). Black Pearl 2000(R) was used as a supporting material, while an oxide sol was prepared ...
Drying of suspensions in the draft tube spouted bed
(Canadian Society for Chemical Engineering, 2004)
A draft tube spouted bed dryer with inert particles was used for drying suspensions. The effects of the operating conditions on dryer throughput and product quality were investigated. Experiments were performed in a ...
Heavy metals in petroleum-contaminated surface soils in Serbia
(Societa Chimica Italiana, 2004)
Investigation of heavy metal contamination levels as well as their association types with substrates in petroleum-contaminated surface soil was carried out using modified sequential extraction method. In that way, ...
