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, ...
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, ...
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 ...
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 ...
Chain conformational statistics and mechanical properties of elastomer composites
(Progress in Advanced Materials and Processes: Proceedings of the Fifth Jugoslav Materials Research Society, YUCOMAT V, 2004)
A new equation of state for elastomer network under constrains due to fillers has been proposed and verified for two most common and industry important rubbers, natural rubber and styrene-butadiene rubber. A series of ...
Electrophoretic deposition of boehmite coatings on titanium from aqueous sols
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
The electrophoretic deposition from sots and colloidal suspensions of ceramic powders has many advantages over conventional ceramic powder processing methods. In this way it is possible to control the thickness and ...
Apparent enthalpies of activation for oxygen reduction at Pt3Co electrode in alkaline solution
(Progress in Advanced Materials and Processes: Proceedings of the Fifth Jugoslav Materials Research Society, YUCOMAT V, 2004)
Oxygen reduction (OR) at a Pt3Co alloy electrode has been examined in alkaline solutions of different pH's in the temperature range from 274 to 313 K. At all temperatures, two distinct E-log j rep-ions are observed. At low ...
Cell support studies aimed for cartilage tissue engineering in perfused bioreactors
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
Cartilage tissue engineering based on chondrogenic cells seeded onto biodegradable polymer supports and cultivated in bioreactors can potentially become an effective method for creating functional tissue equivalents. ...
