Degradation of transformer oil on the basis of polychlorinated bifenyls without degrading the existing quality of the environment / Degradacija transformatorskog ulja na bazi polihlorovanih bifenila bez narušavanja postojećeg kvaliteta životne sredine
(Elektroprivreda, 2003)
This paper deals with results of laboratory experiments referring to transformer oil chemical degradation on the basis of polychlorinated bifenyls, results referring to rinsing of transformer insulation material, as well ...
Chemical modification of β-lactoglobulin by quinines / Hemijske modifikacije β-laktoglobulina hinonima
(Serbian Chemical Society, 2003)
The avarone/avarol quinone/hydroquinone couple, as well as their derivatives show considerable antitumor activity. In this work, covalent modifications of β-lactoglobulin, isolated from cow milk, by avarone, its model ...
Energy spectra and dynamics of surface states on silicon investigated by the photoacoustic method
(AIP Publishing, 2003)
The spectral and dynamic characteristics of surface energy states (SES) on a Si wafer are investigated by photoacoustic (PA) spectroscopy. The PA spectra were measured as a function of the wavelength and modulation frequency ...
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 ...
Dithiophenes and other constituents of roots of Centaurea nicolai
(Oxford : Pergamon-Elsevier Science Ltd, 2003)
Centaurea nicolai Bald. is an endemic species found in the Mediterranean part of Montenegro, and in Albania. Roots of C. nicolai were collected on the south slopes of mountain Rumija on the Adriatic coast of Montenegro.
A glucan from active dry baker’s yeast (Saccharomyces cerevisiae): A chemical and enzymatic investigation of the structure / Glukan iz suvog aktivnog pekarskog kvasca (Saccharomyces cerevisiae) - hemijsko i enzimsko izučavanje strukture
(Serbian Chemical Society, 2003)
The structure of a polysaccharide consisting of D-glucose isolated from the cell-wall of active dry baker’s yeast (Saccharomyces cerevisiae) was investigated by using methylation analysis, periodate oxidation, mass ...
The properties of carbon-supported hydrous ruthenium oxide obtained from RuOxHy sol
(Elsevier, 2003)
Preparation of RuOxHy/carbon black nanocomposite material was performed by the impregnation method starting from RuOxHy sol as a precursor. Black Pearls 2000® (BP) and Vulcan® XC-72 R (XC) were used as supporting materials. ...
