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 ...
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 ...
The roughness analysis of metal coatings by STM technique part III: Analysis of copper coatings electrodeposited with thiourea as brightening additive / Analiza hrapavosti galvanskih prevlaka tehnikom skenirajuće tunelske mikroskopije III deo - analiza prevlaka bakra istaloženih sa tioureom kao aditivom za sjaj
(Belgrade, Serbia : Engineering Society for Corrosion, 2003)
In this work is given the analysis of roughness of copper coatings electrodeposited from a sulfate bath in the presence of thiourea, by methodology which is described in part I of this work. It was shown that the ...
Hyperatomarin, an antibacterial prenylated phloroglucinol from Hypericum atomarium ssp degenii
(American Chemical Society (ACS), 2003)
As shown by quantitative 1H NMR measurements, a lipophilic extract of the aerial parts of Hypericum atomarium ssp. degenii contained a high percentage (3.1% per weight of dried plant material) of a prenylated phloroglucinol ...
Osmotic coefficient of the ZnCl2(aq) at T = 298.15 K
(Elsevier, 2003)
The osmotic coefficient of ZnCl2 (aq) has been measured at T = 298.15 K by the isopiestic method over the range of molalities from (0.4 to 2.4)mol·kg -1 with KCl(aq) as the reference solution. The available literature data ...
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 ...
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. ...
