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 ...
The influence of zinc surface pretreatment on the adhesion of epoxy coating electrodeposited on hot-dip galvanized steel
(Elsevier, 2007)
The adhesion and electrochemical properties of epoxy coatings electrodeposited on hot-dip galvanized steel with and without passive films were investigated during exposure to 3% NaCl. The passive films were formed in hot ...
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 ...
Adhesion of epoxy cataphoretic coatings on Zn alloys / Адхезија епоксидних катафоретских превлака на легурама цинка
(Belgrade : Serbian Chemical Society, 2007)
One of the most important factors in corrosion prevention by protective coatings is the loss of coating adhesion under environmental influence. In this work, the adhesion of epoxy cataphoretic coatings was examined on steel ...
Are Chelate Rings Aromatic? Calculations of Magnetic Properties of Acetylacetonato and o-Benzoquinonediimine Chelate Rings
(American Chemical Society (ACS), 2007)
The aromaticity of the chelate rings of acetylacetonato (acac) and o-benzoquinonediimine (bqdi) ligands was
investigated theoretically by calculating nucleus-independent chemical shifts (NICS). The calculations were ...
Synthesis, characterization and crystal structure of palladium(II) complexes containing edta tetraalkyl ester ligands
(Ceska Republika : Akademie Ved Ceske Republiky, 2007)
The reaction of solutions of tetraalkyl ethylenediamine-N,N,N′, N′-tetraacetate esters (alkyl = Me, 1a; Et, 1b) with H 2[PdCl4] led to the complexes [PdCl2(R 4EDTA)] (R = Me, 2a; Et, 2b). The coordination of R4EDTA ligands ...
Effect of pH and human serum albumin on the cytotoxicity of a glucuronide prodrug of 9-aminocamptothecin
(Switzerland : Springer Nature, 2007)
Purpose: 9-aminocamptothecin glucuronide (9ACG) is a prodrug of 9-aminocamptothecin (9AC) that displays potent antitumor activity against human tumor xenografts in nude mice. Camptothecins exist in a pH dependent equilibrium ...
Variability of antioxidant enzyme activity and isoenzyme profile in needles of Serbian spruce (Picea omorika (Panč.) Purkinye)
(Elsevier, 2007)
Variations were studied of the activity and isoenzyme patterns of soluble peroxidase, catalase, catechol oxidase and superoxide dismutase, in needles of the Balkan endemic conifer Serbian spruce, Picea omorika (Panč.) ...
A Cu2+ probe over nizatidine and ranitidine, or in Silico vs. experimentally obtained complexatlon of drugs
(Switzerland : Trans Tech Publications LTD, 2007)
In silico model of title drugs mode of interaction with Cu2+ ion was proposed. A hundred conformations of each drug are used in this study. Examination of drugs interactions with Cu2+ ion were conducted using GRID package. ...
Methods of characterization of multiphase Nd-Fe-B melt-spun alloys
(International Institute for the Science of Sintering, Beograd, 2007)
Nanocomposite permanent magnetic materials based on Nd-Fe-B alloys with a low Nd content are a new type of permanent magnetic material. The microstructure of these nanocomposite permanent magnets is composed of a mixture ...
