Preparation and studies on immobilized alpha-glucosidase from baker's yeast Saccharomyces cerevisiae / Добијање и проучавање имобилизације α-глукозидазе из пекарског квасца Saccharomyces cerevisiae
(Belgrade : Serbian Chemical Society, 2007)
α-Glucosidase from S. cerevisiae was covalently immobilized onto Sepabeads EC-EA by the glutaraldehyde method. An analysis of the variables controlling the immobilization process is first presented and it is shown that the ...
Formation of Disperse Silver Deposits by the Electrodeposition Processes at High Overpotentials
(Esg, Belgrade, 2012)
In this study, electrodeposition of silver from nitrate solution at the high overpotentials was analyzed. Morphologies of silver deposits obtained at the different overpotentials and with the different electrodeposition ...
Hydrogen Evolution on Columnar Ni Thin Films Obtained by GLAD
(Esg, Belgrade, 2017)
Nanostructured nickel thin films were deposited on glass using glancing angle deposition (GLAD) technique. Cross-sectional field emission scanning electron microscopy images have shown that obtained Ni thin films consist ...
Palladium(II) complexes with R2edda derived ligands. Part VI. 0,0-Diisopropyl ester of N,N'-1,2-ethanediylbis-L-leucine, dihydrochloride dihydrate and its palladium(II) complex: Synthesis and characterization / Kompleksi paladijuma(II) sa ligandima R2edda tipa.

Comparative Spectroscopic Characterization of the Basic and the Higher Fullerenes
(Taylor & Francis Inc, Philadelphia, 2013)
The basic C-60 and C-70, and the higher fullerenes, mainly C-76 and C-84, were extracted by original procedures, with p-xylene and the mixture of xylenes from the samples of initial carbon soot, produced in electrical arc. ...
Comparative study of the phenolic composition of seeds from grapes cv cardinal and alphonse lavallee during last month of ripening
(Chiriotti Editori, 2012)
During the last month of ripening, the phenolic composition of seeds from two widely distributed table grapes, cv Cardinal and Alphonse Lavallee, was determined by HPLC/DAD/ESI/MS. Besides, the concentrations of nutrients ...
Kinetics of the Formation of Poly(methyldecylsiloxane) by Hydrosilylation of Poly(methylhydrosiloxane) and 1-Decene
(Switzerland : Trans Tech Publications LTD, 2007)
Poly(methylhydrosiloxane) [PMHS], prepared by siloxane equilibration reaction, was used for the hydrosilylation with 1-decene to obtain poly(methyldecylsiloxane) [PMDS]. Pt(0)-1,3-divinyltetramethyldisiloxane complex was ...
