The crystallization and optical properties of LiNbO3 single crystals / Kristalizacija i optičke osobine monokristala LiNbO3
(Belgrade : Serbian Chemical Society, 2000)
LiNbO3 single crystals were grown by the Czochralski technique in an air
atmosphere. The critical crystal diameter Dc = 1.5 cm and the critical rate of rotation wc
= 35 rpm were calculated from the dynamic of fluids ...
Isolation and antimicrobial activity of anthraquinones from some species of the lichen genus Xanthoria / Изоловање и антимикробна активност антрахинона неких врста лишајева рода Xanthoria
(Belgrade : Serbian Chemical Society, 2000)
The isolation of six anthraquinones erythroglaucin, physcion, xanthorin, emodin, fallacinal, teloschistin, from three species of the lichen genus Xanthoria (X.fallax, X.elegans and X.policarpa) is reported. Physcion is the ...
Peracids oxidation of cholesta-5,8-dien-3β-yl acetate / Oksidacija holesta-5,8-dien-3β-il acetata sa perkiselinama
(Serbian Chemical Society, 2000)
Expoxidation of cholesta-5,8-dien-3β-yl acetate (1) with peracids takes place preferentially at the more highly substituted Δ8-olefinic double bond to give: (a) with monoperphthalic acid, 8α,9α-epoxycholest-5-en-3β-yl ...
Antimicrobial activity of essential oils and ethanol extract of Phlomis fruticosa L. (Lamiaceae)
(John Wiley and Sons LtdJohn Wiley and Sons Ltd., 2000)
The essential oils and an ethanol extract of Phlomis fruticosa L. were evaluated for antibacterial and antifungal activities. Seven bacterial and seven fungal species were used. Among them were human, animal and plant ...
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 ...
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 ...
