Liquefaction behaviour of Kolubara soft brown coal
(Elsevier B.V., 1994)
The behaviour of Kolubara soft brown coal during direct liquefaction by catalytic hydrogenation was studied and was compared with the Banovići brown coal investigated previously. A sample of washed and dried coal was ground ...
Sinteza i karakterizacija fosforom interkalisanih molibdenskih bronzi
(Belgrade : Serbian Chemical Society, 1994)
Nedavno publikovani radovi 1,2 o termalno indukovanim faznim transformacijama fosforvolframove heteropolikiseline, pokazali su da se ova jedinjenja opšte formule H3+xAM12O40.nH2O (x=0-1; A=P, Si, B, As i Ge; M=Mo, W i V; ...
Modifikacije hemoglobina kod alkoholičara
(Belgrade : Serbian Chemical Society, 1994)
Za istraživanja acctaldchidnih adukata hemoglobina upotrcbljcni su liemolizati lironičnih alkoholičara, koji nisu bili pod terapijom i hemolizati zdravih osoba radi poredenja. Pored toga analizirana su i acetaldchidna ...
Effect of sulfur oxides on surface state and carbon monoxide oxidation activity of CuxZnl-xCr204 mixed oxides
(Elsevier B.V., 1994)
The effect of mixed sulfur oxides pretreatment on the surface state and carbon monoxide oxidation activity of CuxZn1−xCr2O4 mixed oxides, has been investigated using X-ray photoelectron spectroscopy (XPS) and kinetic ...
Корунд из дистенско-силиманитског шкриљца Боболош-Брза Паланка
(Geoinstitut, 1994)
Korund iz distensko silimanitskog škriljca lokalnosti Bobološ je detaljnije mineraloško-kristalografski ispitan pomoću nekoliko metoda. Dobijeno je učešće korunda od oko 15 %, čime je ova stena postala značajna kao sirovina ...
Oxygen reduction on Au(111) and vicinal Au(332) faces: A rotating disc and disc-ring study
(Elsevier, 1994)
The kinetics of oxygen reduction on the Au(111) surface in acidic solution has been re-examined by means of a rotating disc electrode technique. Its vicinal Au(332) = Au[6(111) × (111)] surface has been chosen to examine ...
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], ...
Ispitivanje dinamike protonskih vrsti kod fosformolibdenove kiseline metodom infracrvene i mikro-ramanske spektroskopije
(Belgrade : Serbian Chemical Society, 1994)
U ovom radu izloženi su najnoviji rezultati sistematskog ispitivanja heteropolikiselina kao protonskih provodnika, posebno 29-hidrata fosformolibdenove koseline (MoPA-29).
Metodama infracrvene i mikro-Ramanske spektroskopije, ...
Structural effects in electrocatalysis: oxygen reduction on platinum low index single-crystal surfaces in perchloric acid solutions
(Elsevier, 1994)
Oxygen reduction has been studied in 0.1 M HClO4 on the platinum low index surfaces, employing a hanging meniscus rotating-disk technique. A special cleaning procedure has been developed to remove impurities from the surface ...
Photochemically induced mercuric oxide - iodine oxidation of some unsaturated steroid compounds
(Pergamon, 1994)
Photochemically induced HgO/I2 oxidation of cholest-5-en-3α-ol (6) and cholest-5-en-3β-ol (7) afforded (Scheme 3) products arising from the corresponding alkoxy radicals (12, 13 and 14a,b) and from attack of the I2O ...
