Further sesquiterpene lactones from Anthemis carpatica
(Pergamon, 2000)
A new germacranolide, (E)-1α, 10β-epoxy-3β-acetoxy-6α-hydroxygermacra-4,11(13)-dien-12,8α-o lide, together with nine new highly oxygenated guaiadien-12,6α-olides of anthemolide, and cumambrin type were identified in the ...
Far infrared and transport properties of single crystal PBTE samples doped with Ce
(Bucharest : National Institute of Research and Development for Optoelectronic, 2000)
Single crystal samples of lead telluride doped with cerium were made using the Bridgman technique. Single crystals could be easily cleaved parallel to the (002) plane. Room temperature far infrared reflectivity was measured ...
A contribution to the knowledge of electrochemical deposition of W induced by Ni
(Elsevier Sequoia SA, 2000)
It was found that codeposition of Ni and W from an ammonia and citrate-containing electrolyte, is very sensitive to changes in operating conditions. The Ni-W alloy deposit exhibited sensitivity of chemical composition and ...
Direct liquefaction of soft brown coal from the Kosovo Basin / Likvefakcija mekog mrkog uglja Kosovskog Basena
(Association of the Chemical Engineers of Serbia, 2000)
The behaviour of Kosovo Basin (Yugoslavia) soft brown coal was studied during a direct liquefaction process by catalytic hydrogenation. A stream of hydrogen was passed through a tetralin dispersion of the pulverized coal ...
Characterization and carbon monoxide oxidation activity of La1-ySryCr1-xRuxO3 perovskites / Katalitička svojstva La1-ySryCr1-xRuxO3 perovskita u oksidaciji ugljenmonoksida
(Serbian Chemical Society, 2000)
The oxidation of CO over La1-ySryCr1-xRuxO3 perovskite type oxides with y=0.3 and 0 £x £0.100 have been studied. X-ray fluorescence analysis confirmed that content of elements in the bulk corresponds to the established ...
The structure of bright zinc coatings / Struktura sjajnih prevlaka cinka
(Serbian Chemical Society, 2000)
The structures of bright zinc coatings obtained from acid sulfate solutions in the presenceof dextrin/salicylaldehyde mixture were examined. It was shown by the STM technique that the surfaces of bright zinc coatings are ...
The effect of the presence of alcohol in the dispersing phase of oxide sols on the properties of RuO2-TiO2/Ti anodes obtained by the sol-gel procedure / Uticaj prisustva alkohola u disperznoj sredini oksidnih solova ha osobine RuO2-TiO2/Ti anoda dobijenih sol-gel postupkom
(Serbian Chemical Society, 2000)
The effect of the addition of ethanol and 2-propanol to the dispersing phase of TiO2 and RuO2 sols mixture on the morphology and, consequently, on the electrochemical properties of the sol-gel obtained activated titanium ...
