Mass spectrometry analysis of polychlorinated biphenyls: Chemical ionization and selected ion chemical ionization using methane as a reagent gas
(Serbian Chemical Society, 2000)
In the present paper a quadrupole ion trap mass spectrometer, coupled with a gas chromatograph, was used to compare the electron impact ionization (El) and chemical ionization (Cl) technique, in terms of their selectivity ...
Modulation of the mechanical properties of tissue engineered cartilage
(IOS Press, Amsterdam, 2000)
Cartilaginous constructs have been grown in vitro using chondrocytes, biodegradable polymer scaffolds, and tissue culture bioreactors. In the present work, we studied how the composition and mechanical properties of ...
The devitrification of PbO-B2O3-ZnO glass doped with Li2O / Rastakljivanje PbO-B2O3-ZnO stakla sa dodatkom Li2O
(Serbian Chemical Society, Belgrade, 2000)
In this paper the effect of the addition of Li2O on the crystallization behavior of PbO-B2O3-ZnO glass was investigated by the differential thermal analysis (DTA) and X-ray powder diffraction (XRPD) methods. The crystallization ...
The effect of low-temperature plasma pretreatment on wool printing
(Amer Assoc Textile Chemists Colorists-Aatcc, Res Triangle Pk, 2000)
The application of radio-frequency capacitively coupled plasma for the treatment of wool was studied. The influence of plasma parameters on the printing and mechanical properties of wool was determined. Results after plasma ...
The thermal degradation of poly(iso-butyl methacrylate) and poly(sec-butyl methacrylate) / Termička degradacija poli(iso-butil metakrilata) i poli(sec-butil metakrilata)
(Serbian Chemical Society, Belgrade, 2000)
The non-oxidative thermal degradation of poly(iso-butyl methacrylate) and poly(sec-butyl methacrylate) was investigated by studying changes in the polymer residue. Due to the different number of β-hydrogens in their ester ...
A comparative LFER study of the reactivity of pyridineacetic, pyridineacetic acids N-oxide and substituted phenylacetic acids with diazodiphenylmethane in various alcohols / Komparativna LFER studija reaktivnosti piridinsirćetnih, piridin-N-oksid-sirćetnih kiselina i supstituisanih fenilsirćetnih kiselina sa diazodifenilmetanom u različitim alkoholima
(Serbian Chemical Society, Belgrade, 2000)
Rate constants have been determined for the reactions of diazodiphenylmethane (DDM) with 3- and 4-pyridineacetic acid, 3- and 4-pyridineacetic acid N-oxide and some meta- and para-substituted phenylacetic acids in twelve ...
The effect of Zn-Ni sublayers on the corrosion behaviour and thermal stability of epoxy coatings electrodeposited on steel / Uticaj Zn-Ni podslojeva na koroziono ponašanje i termičku stabilnost epoksidnih elektroforetskih prevlaka na čeliku
(Serbian Chemical Society, Belgrade, 2000)
The electrochemical and transport properties, as well as the thermal stability of epoxy coatings electrodeposited on steel and steel modified by Zn-Ni alloys were investigated during exposure to 3 % NaCl. The Zn-Ni alloys ...
Determination of americium-241 in sediments by gamma spectroscopy / Određivanje americijuma-241 gama spektroskopijom
(Serbian Chemical Society, Belgrade, 2000)
A radiochemical method is given for the determination of Am-241 from the global fallout in sediments. The concept of a concentration step to separate Am-241 from the bulk of the sample (1-2 kg wet) by coprecipitation ...
The kinetics of the reaction of 6-substituted nicotinic acids and some p-substituted benzoic acids with diazodiphenylmethane in various alcohols / Kinetika reakcija 6-supstitutisanih nikotinskih kiselina i nekih p-supstituisanih benzoevih kiselina sa diazodifenilmetanom u različitim alkoholima
(Serbian Chemical Society, Belgrade, 2000)
Rate constants have been determined for the reactions of diazodiphenylmethane with a number of 6-substituted nicotinic acids and p-substituted benzoic acids in twelve alcohols. A comparative study was used to evaluate and ...
A new approach to the velocity field investigation in case of the entry flow in curved pipes with circular cross section
(Springer Wien, Wien, 2000)
In this paper an analysis of a laminar flow in a bend preceded by the straight section is presented. The flow is supposed to be unperturbed far upstream, while far downstream it becomes fully developed. In the vicinity of ...
