Electrodeposition of cobalt powders with novel three-dimensional structure
(Metalurgija, 2011)
Novel three-dimensional cobalt powder structures were successfully prepared by electrodeposition. Electrodeposited cobalt powder was characterized by scanning electron microscopy (SEM) and light microscopy. It was possible ...
Elektrohemijska redukcija tartrazina na kompozitnim pilarena glina/ugljenik/nafion elektrodama
(Savez inženjera i tehničara Srbije, 2011)
Bentonitna glina iz rudnika Bogovina (Srbija) pilarena je Al3+ i Al3+/Fe3+ polioksokatjonima. Ispitana je mogućnost primene pilarenih glina za elektrohemijsku detekciju tartrazina iz rastvora. Metodom SW voltametrije je ...
Preventing and removing of heat tint / Sprečavanje i uklanjanje termičkog oksida (heat tint)
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2014)
Heat tinting is a thickening of the naturally occurring oxide layer on the surface of the stainless steels during welding. The thickness of the oxide layer next to the weld depends on the temperature, heating time, and ...
The application of the zeolyte powder for the construction of the dense composite membranes for the carbon-dioxide separation / Primena zeolitnih prahova za izradu kompozitnih polimernih membrana za separaciju ugljen-dioksida
