Investigation of ion-beam modified silicon by photoacoustic method
(IEEE Computer Society, 2000)
Thermal, elastic and electronic transport properties of ion-modified silicon samples were investigated by a photoacoustic frequency transmission technique. The experimental photoacoustic data vs the modulating frequency ...
A new heterocyclization product of adhyperforin from Hypericum perforatum (St. John's Wort)
(Molecular Diversity Preservation International, 2000)
Heat transfer in the vertical two-phase flow of coarse particles
(VINCA Institute of Nuclear Sciences, 2000)
Wall-to-bed heat transfer in hydraulic transport of spherical glass particles 1.20,1.94, and 2.98 mm in diameter and in single-phase flow regime was studied. Experiments were performed by transporting spherical glass ...
Selective area epitaxial growth of Hg1-xCdxTe by isothermal vapor-phase epitaxy
(IEEE Computer Society, 2000)
We used mechanical shadow masks, which are made by silicon micromachining, to obtain selective area epitaxial (SAE) growth of (Hg,Cd)Te on CdTe substrates. The layers were grown by isothermal vapor phase epitaxy (ISOVPE) ...
Activity of some disiloxanes toward the cation exchange resin-catalyst in the siloxane equilibration reaction / Aктивност дисилоксана према катјонској јоноимењивачкој смоли - катализатору реакције силоксанске еквилибрације
(Belgrade : Serbian Chemical Society, 2000)
The relative activities of four disiloxanes toward the cation exchange resin, which was used as an equilibration catalyst, were determined in such a way that the equilibrium initialy present in an arbitrary chosen equilibrate ...
The synthesis of some unsaturated 4-substituted-g-lactones / Sinteza nekih nezasićenih 4-substituisanih-g-laktona
(Belgrade : Serbian Chemical Society, 2000)
The synthesis of conjugated and nonconjugated unsaturated 4-substituted lactones
of type 1 and 2 are described. The type 1 lactone was prepared by a two step
procedure employing Bredereck s reagent. The type 2 lactone ...
Lead tetraacetate oxidation of the Diels-Alder adduct of 7-dehydrocholestryl acetate with maleic anhydride / Olovotetraacetatna oksidacija Dils-Adlerovog adukta 7-dehidro-holesteril-acetata sa anhidridom maleinske kiseline
(Belgrade : Serbian Chemical Society, 2000)
The Diels-Alder adduct (3), obtained by cycloaddition of 7-dehydrocholesteryl
acetate (1) and maleic anhydride (2), was heated at ca. 90 oC with a large excess of lead
tetraacetate in pyridine solution for 5 h. Under ...
Determination and structural correlation of the pKa values of p-substituted trans-2,3-epoxy-4-oxo-4-phenylbutanoic acids / Određivanje pKa vrednosti i korelacija sa strukturom p-supstituisanih trans-2,3-epoksi-4-okso-4-fenilbutanskih kiselina
(Srpsko hemijsko društvo, Beograd, 2000)
The pKa values for a series of eight p-substituted trans-2,3-epoxy-4-phenyl butanoic acids (p-substituted trans-β-aroylepoxyacrylic acids) have been determined potentiometrically in aqueous media at 25 °C at an ionic ...
The crystal structure of 14-oxo-13,14-seco-5α-cholest-13(18)-en-3β-yl acetate and the assignment of the configuration of its acetoxy derivatives / Kristalna struktura 14-okso-13,14-seko-5α-holest-13(18)-en-3β-il-acetata i određivanje konfiguracije njegovih acetoksi derivata
(Serbian Chemical Society, 2000)
The crystal structure of 14-oxo-13,14-seco-5α-cholest-13(18)-en-3β-yl acetate (2), obtained (in addition to the (E)-Δ12-isomer 3) by oxidative fragmentation of the C(13)-C(14) bond of 14α-hydroxy-5α-cholestan-3β-yl acetate ...
Effect of methyl oleate and Tween 80 on the antibiotic productivity and the fatty acid composition of the total lipids of Streptomyces hygroscopicus CH-7 / Dejstvo metil oleata i Tween-a 80 ha produkciju antibiotika i sadržaj masnih kiselina u ukupnim lipidima soja Streptomyces hygroscopicus CH-7
(Serbian Chemical Society, 2000)
The effects of methyl oleate and Tween 80, hexaene H-85 production stimulators, on the fatty acid composition of the total lipids of S. hygroscopicus CH-7 were investigated. Besides oleic acid in the biomass, an increase ...
