The possibilities of applying thermogravimetry in the characterisation of wood types / Mogućnosti primene termogravimetrije u karakterisanju drvnih vrsta
(Faculty of Technology, Novi Sad, 2000)
Thermogravimtery (TG) is a convenient method for the routine, as well as non-standard characterisation of polymeric materials. The changes in wood under various heating conditions were followed and on the basis of the ...
Electrochemical studies on LaNi4.15Co0.43Mn0.40Fe0.02 metal hydride alloy
(Elsevier Science Sa, Lausanne, 2000)
Electrochemical studies were performed on LaNi4.15Co0.43Mn0.40Fe0.02. alloy electrode. The kinetics of the electrochemical hydrogen absorption/desorption reaction was studied by DC polarization and AC impedance measurements. ...
Immobilization of yeast cells in small alginate beads using electrostatic droplet generation / Primena postupka elektrostatičke ekstruzije pri dobijanju alginatnih čestica malih dimenzija sa imobilisanim ćelijama pivskog kvasca
(Faculty of Technology, Novi Sad, 2000)
In beer brewing with immobilized yeast cells it is very important to minimize the mass transfer resistance, problem associated with large diameter beads, because the mass transfer limitations may force the cells to alter ...
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 ...
Effects of substituents on the electronic absorption spectra of 3-N-(4-substituted phenyl)-5-carboxy uracils in different solvents: Part II / Efekat supstituenata na apsorpcione spektre 3-N-(4-supstituisanih fenil)-5-karboksi uracila u različitim rastvaračima - deo II
(Serbian Chemical Society, Belgrade, 2000)
Absorption spectra of some 3-N-(4-substituted phenyl)-5-carboxy uracils, previously determined in twelve solvents, are correlated with substituent sp+ values or by dual substituent parameter correlations involving sI and ...
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 ...
Mixed ligand Co(II), Ni(II) and Cu(II) complexes containing terephthalato ligands. Crystal structures of diaqua(2,2 '-dipyridylamine)(terephthalato)metal(II) trihydrates (metal = cobalt or nickel)
(Pergamon-Elsevier Science Ltd, Oxford, 2000)
A series of nine ternary Co(II), Ni(II) and Cu(II) complexes with some aromatic diamines and dianion of terephthalic acid (tpht) have been synthesized and characterized by elemental analysis, magnetic susceptibility ...
The thermal degradation of poly(di-itaconates) / Termička degradacija poli(di-itakonata)
(Association of Chemical Engineers of Serbia, 2000)
The thermal degradation of poly(di-itaconates) is discussed with special emphasis on the Influence of the nature of the ester substituent. It was established that the following reactions occur during the thermal degradation ...
