Comparative study of ethanol oxidation at Pt-based nanoalloys and UPD-modified pt nanoparticles / Uporedno ispitivanje oksidacije etanola na platinskim nanolegurama i Pt nanočesticama modifikovanim podpotencijalnom depozicijom
(Serbian Chemical Society, 2010)
The activity of two alloys, Pt3Sn/C and Pt3Ru2/C, was compared with the activity of Pt/C modified with corresponding amounts of SnUPD (≈25%) and RuUPD (≈40%) in the oxidation of ethanol. Pt3Sn/C, Pt3Ru2/C and Pt/C catalysts ...
Comparison of α-amylase isoforms from the midgut of Cerambyx cerdo L. (Coleoptera: Cerambycidae) larvae developed in the wild and on an artificial diet / Uporedna analiza izoformi α-amilaze iz srednjeg creva larvi Cerambyx cerdo L. (Coleoptera: Cerambycidae) iz prirode i gajenih na veštačkoj podlozi
(Inst Bioloska Istrazivanja Sinisa Stankovic, Beograd, 2010)
α-Amylase isoforms of Cerambyx cerdo larvae from the wild (ML and SL) and reared in the laboratory (ADL) were compared. Three amylase isoforms were presented in the SL and ML extracts while two isoforms were presented in ...
Change of isoprenoids, steranes and terpanes during ex situ bioremediation of mazut on the industrial scale / Promena izoprenoidne, steranske i terpanske frakcije tokom ex situ bioremedijacije mazuta na industrijskom nivou
(Serbian Chemical Soc, Belgrade, 2010)
This paper presents the results of an ex situ bioremediation of soil contaminated by mazut (heavy residual fuel oil) in the field scale (600 m3). The treatment-bed (thickness 0.4 m) consisted of mechanically mixed ...
Methylprednisolone and its related substances in freeze-dried powders for injections / Метилпреднизолон и његове сродне супстанце у лиофилизату за раствор за инјекције
(Journal of the Serbian Chemical Society, 2010)
In this work, the behavior of the active pharmaceutical substances methylprednisolone (in a form of methylprednisolone sodium succinate) in finished pharmaceutical dosage form, i.e., freeze-dried powder for injections, was ...
Fluidized bed combustion of pesticide-manufacture liquid wastes / Sagorevanje tečnog otpada fabrike pesticida u fluidizovanom sloju
(Serbian Chemical Society, 2010)
Industrial liquid wastes can be in the form of solutions, suspensions, sludges, scums or waste oil and have organic properties. The objective of this work was to demonstrate the technical feasibility of a fluidized bed as ...
Synthesis, structure and solvatochromic properties of 3-cyano-4,6-diphenyl-5-(3- and 4-substituted phenylazo)-2-pyridones / Sinteza, struktura i solvatohromna svojstva 3-cijano-4,6-difenil-5-(3- i 4-supstituisanih fenilazo)-2-piridona
(Serbian Chemical Society, 2010)
A series of some new pyridone arylazo dyes was synthesized from the corresponding diazonium salts and 3-cyano-4,6-diphenyl-2-pyridone using the classical reaction for the synthesis of the azo compounds. The structures of ...
