Direct hydroliquefaction of a low rank soft brown coal
(Elsevier B.V., 1998)
The behaviour of the soft brown coal from the Kostolac Mine (Serbia, Yugoslavia) was investigated during hydroliquefaction carried out in a batch reactor by direct catalytic hydrogenation of the pulverized coal (- 160 μm) ...
Erratum to: “A simple approximative method for determination of Auger 1 lifetime in degenerate narrow gap semiconductors (Infrared Physics 34 (1993) 601-605)”
(Elsevier, 1995)
An error appeared in Fig. 3 in the part regarding low electron concentrations.
Međusobna zavisnost uslova sinterovanja, mikrostrukture i magnetnih svojstava sinterovanih SmCo5 magneta
(Savez inženjera metalurgije Srbije, 1999)
Razmatran je uticaj procesnih promenljivih na mikrostrukturu i magnetna svojstva sinterovanih SmCo5 magneta. Neposredan uticaj mikrostrukture na magnetna svojstva sinterovanih uzoraka omogućava sagledavanje procesa dobijanja ...
Phase-structure analysis of brass by anodic linear-sweep voltammetry
(Springer, 1992)
Anodic linear-sweep voltammetry (ALSV) was applied to electrodeposited alloy layers and to metallurgically obtained Cu−Zn alloys of different composition and structure. Metallurgically obtained samples covered the range ...
Selenium content and distribution in rat tissues irradiated with gamma rays
(Heidelberg : Springer, 1992)
The effects of supplementation with selenous yeast and ionizing radiation on selenium (Se) content and distribution were evaluated in rat tissues (liver, kidney, spleen, heart, muscle, blood, front brain, hind brain, ...
Identification of intermetallic compounds in thin layers of electrodeposited Cu–Cd alloys using electrochemical techniques
(USA :Taylor & Francis INC, 1991)
An attempt was made to analyse the phase structure of thin layers of electrodeposited Cu–Cd alloys using anodic linear sweep voltammetry combined with a potentiostatic pulse technique (ALSV–PPT). The results were compared ...
Regioselectivity in Cyclofunctionalization of Olefinic Alcohols with Benzeneselenenyl Halides at Different Temperatures
(Wiley, 1992)
The regioselectivity in cyclofunctionalization of some acyclic olefinic alcohols with benzeneselenenyl halides (PhSeCl and PhSeBr) at different temperatures (−78°C, 0°C and room temperature) is investigated. It has been ...
Sesquiterpene lactones from Achillea crithmifolia
(American Chemical Society, 1994)
The isolation of three highly oxygenated guaianolides, desacetyl-1α-4α- dihydroxybishopsolicepolide [1], its 4β-hydroxy epimer 2 (a new compound), and 1β,2β:3β,4β-diepoxy-8α,10α-dihydroxyguai-12(13)-en-12,6α-olide [3], ...
Sesquiterpene lactones from Achillea crithmifolia
(Elsevier, 1991)
The isolation of guaianolides rupicolin-A, rupicolin-B, their acetates and a new germacranolide 1β,10α-epoxy-3β,9β-diacetoxy-11α,13-dihydrocostunolide, identified by means of PS DQF COSY and PS NOESY, from Achillea ...
Oxygen reduction on single crystal platinum electrodes in phosphoric acid solutions / Redukcija kiseonika na monokristalnim platinskim elektrodama u rastvorima fosforne kiseline
(Belgrade : Serbian Chemical Society, 1999)
Oxygen reduction reaction has been studied on Pt low index planes in 0.1 M and 85% H3PO4 using hanging meniscus rotating disc electrode technique. The first-order kinetics of O2 reduction reaction was found for all three ...
