Determination of acid-activated bentonite affinity towards soybean oil pigments during the decolourization process / Određivanje afiniteta kiselinski aktiviranog bentonita prema pigmentima sojinog ulja tokom procesa dekolorizacije
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije, Beograd, 2003)
Acid-activated bentonite clays partially or entirely remove pigments from oil by absorption in the process of its decolorization. However, in addition to pigments, they also remove other undesirable components such as ...
Lignans from the plant species Achillea lingulata / Лигнани биљне врсте Achillea lingulata
(Serbian Chemical Society, 2003)
Five lignans with a 2.6-diaryl-3.7-dioxabicyclo[3.3.0]octane skeleton, epieudesmin, kobusin, pinoresinol, fargesin and sesartemin, were isolated from the aerial parts and roots of Achillea lingulata. Their structures were ...
Oxidative fragmentation of 5-hydroxy-1-oxo-5α-cholestan-3β-yl acetate / Oksidativne fragmentacije 5-hidroksi-1-okso-5α-holestan-3β-il-acetata
(Serbian Chemical Society, 2003)
5-hydroxy-1-oxo-5α-cholestan-3β-yl acetate (11) was prepared in 5 steps starting from (E)-3β-acetoxy-5,10-seco-1(10)-cholesten-5-one (6). Treatment of the 1-oxo-5-hydroxy derivative 11 with lead tetraacetate (LTA) (under ...
The effect of ageing on YBa2Cu3O7-x obtained by the photoacoustic method
(Belgrade: International Institute for the Science of Sintering, 2003)
Thermal diffusivity and electric transport properties of fourteen years old superconducting YBa2Cu3O7-x pellets were obtained using the photoacoustic transmission technique and then compared with freshly made superconducting ...
Electrochemically deposed Ni/W composite coatings obtained under constant and pulsating current regimes / Kompozitne Ni/WC prevlake dobijene elektrohemijskim taloženjem konstantnom i pulsirajućom strujom
(Belgrade, Serbia : Engineering Society for Corrosion, 2003)
The properties of composite coatings are dependent on properties of the base metal, as well as on properties of incorporating particles. The Ni / W composite coatings were obtained by electro deposition from commercially ...
