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 use of shade sorting method for the fabrics in garment manufacture / Primena metode sortiranja nijansi tkanine za izradu odevnih predmeta
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2000)
Shade sorting methods are designed with the aim to identify the pieces i.e. coloured materials from different dyelots, that could be used for the manufacture of a single garment in order to keep the colour difference between ...
Synthesis and electrochemical properties of polypyrrole, polyaniline and poly-3-methyl thiophene / Sinteza i elektrohemijska svojstva polipirola, polianilina i poli-3-metiltiofena
(Association of Chemical Engineers of Serbia, 2000)
In this article, the results of a study of the electrochemical polymerization of pyrrole and the chemical polymerization of pyrrole, aniline and 3-methyl thiophene initiated by FeCh are presented. The electrochemical ...
Stability of chromium(III)-oxide sol in the presence of inorganic anions
(Trans Tech Publications Ltd, Durnten-Zurich, 2000)
Stability of chromium(III)-oxide sol upon the addition of various electrolytes (chloride, sulfate, and ferrocyanate) was studied by a potentiometric titration method. The critical coagulation concentration was determined ...
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 ...
Glycosaminoglycan deposition in engineered cartilage: Experiments and mathematical model
(Wiley-Blackwell, Malden, 2000)
Functional cartilaginous constructs for scientific research and eventual tissue repair were cultivated in bioreactors starting from chondrocytes immobilized on polymeric scaffolds. The scaffolds gradually degraded as the ...
Bi adsorption on Pt(111) in perchloric acid solution: A rotating ring-disk electrode and XPS study
(Royal Soc Chemistry, Cambridge, 2000)
The surface electrochemistry of reversibly and irreversibly adsorbed bismuth (Bi-ad) was studied on Pt(111) electrodes in 0.1 M HClO4. The valence state of irreversibly adsorbed Bi (Bi-ir) was determined by ex situ X-ray ...
Non-linear frequency response of non-isothermal adsorption controlled by micropore diffusion with variable diffusivity / Nelinearni frekventni odziv neizotermnog adsorpcionog sistema čija je kinetika kontrolisana difuzijom kroz mikropore sa promenljivom difuzivnošću
(Serbian Chemical Society, Belgrade, 2000)
The concept of higher order frequency response functions (FRFs) is used for the analysis of non-linear adsorption kinetics on a particle scale, for the case of non-isothermal micropore diffusion with variable diffusivity. ...
Formic acid oxidation on pure and Bi-modified Pt(111): Temperature effects
(Amer Chemical Soc, Washington, 2000)
Temperature effects on the kinetics of formic acid electrooxidation are studied on Pt(111) and on Pt(111) modified by irreversibly adsorbed Bi under both potentiodynamic and potentiostatic conditions. We propose two modes ...
