Reflection and structural characteristics of semi-bright and mirror bright nickel coatings / Refleksione i strukturne karakteristike polusjajnih i ogledalski sjajnih prevlaka nikla
(Serbian Chemical Society, 2002)
The reflection and structural characteristics of the nickel coatings obtained in the presence of a basic brightening addition agent only, and of both a basic and top brightening addition agent are examined. It is shown ...
The representative particle of copper powder and branch of copper dendrites / Reprezentativna čestica bakarnog praha i grananje dendrita bakra
(Serbian Chemical Society, 2002)
Electrochemically deposited copper powders, which are formed of particles of different size and morphology, are characterized by some properties like specific surface and apparent density. Aprocedure of the determination ...
The retention behaviour of some cholic acid derivatives on different adsorbents
(Research Inst Medicinal Plants, Budakalasz, 2002)
The thin-layer chromatographic behavior of cholic acid and fourteen of its synthetic derivatives has been studied in six reversed-phase and three normal-phase systems. Four significantly different adsorbents were used - ...
