AC Impedance tracking of glassy carbon activation
(Serbian Chemical Society, Belgrade, 2010)
Carbon materials, due to their physical and chemical properties, have found wide application in different electrochemical systems. They are often used as substrates for supercapacitors and different types of electrocatalysts. ...
Millimeter Wave Antenna Array with Circular Polarization
(European Microwave Week 2010, EuMW2010: Connecting the World, Conference Proceedings - European Micr, 2010)
Loop radiation elements with circular polarization radiation pattern are investigated. The research includes, also, two-dimensional array with loop elements and feeding network on the same dielectric substrate. Simulation ...
Synthesis, characterization and in vitro cytotoxicity studies of platinum(IV) complexes with thiouracil ligands
(Elsevier, 2010)
Reactions of [PtMe3(bpy)(Me2CO)][BF4] (2) with the thionucleobases 2-thiouracil (s2Ura), 4-thiouracil (s 4Ura) and 2,4-dithiouracil (s2s4Ura) resulted in the formation of complexes of the type [PtMe3 (bPy)(L-κS)] [BF4] (L= ...
The electrochemical reduction of trinitrotoluene on a platinum wire modified by chemisorbed acetonitrile
(Elsevier, 2010)
The electrochemical reduction of 2,4,6-trinitrotoluene (TNT) was investigated by cyclic voltammetry on a platinum electrode in aqueous sodium chloride solutions with acetonitrile containing different concentrations of TNT. ...
Thermal diffusivity of single crystal Bi0.9Sb0.1
(International Institute for the Science of Sintering, Beograd, 2010)
A single crystal Bi0.9Sb0.1 ingot was synthesized using the Bridgman technique. Thermal diffusivity and electronic transport properties of single crystal cleaved plates (00l) were determined from PA photoacoustic phase and ...
Fast evaluation of periodic operation of a heterogeneous reactor based on nonlinear frequency response analysis
(Elsevier, 2010)
The concept of higher-order frequency response functions(FRFs), which is based on Volterra series representation of nonlinear systems, is used to analyse the time-average performance of a perfectly mixed reactor subject ...
Izoforme eksterne invertaze kvasca Saccharomyces cerevisiae
(Универзитет у Београду, Хемијски факултет, 2010)
Četiri izoforme eksterne invertaze (EINV1, EINV2, EINV3 i EINV4) iz kvasca S. cerevisiae izolovane su izoelektričnim i etanolnim taloženjem, jonoizmenjivačkom hromatografijom na različitim QAE kolonama i gel hromatografijom. ...
Synthesis, structure and characterization of novel Cd(II) and Zn(II) complexes with the condensation product of 2-formylpyridine and selenosemicarbazide Antiproliferative activity of the synthesized complexes and related selenosemicarbazone complexes
(Elsevier Science Inc, New York, 2010)
Two novel Cd(II) and Zn(II) complexes with the condensation product of 2-formylpyridine and selenosemicarbazide were synthesized. The structure of Cd(II) complex was determined by X-ray crystallography. The ligand is ...
Comparative study of ethanol oxidation at Pt-based nanoalloys and UPD-modified pt nanoparticles / Uporedno ispitivanje oksidacije etanola na platinskim nanolegurama i Pt nanočesticama modifikovanim podpotencijalnom depozicijom
(Serbian Chemical Society, 2010)
The activity of two alloys, Pt3Sn/C and Pt3Ru2/C, was compared with the activity of Pt/C modified with corresponding amounts of SnUPD (≈25%) and RuUPD (≈40%) in the oxidation of ethanol. Pt3Sn/C, Pt3Ru2/C and Pt/C catalysts ...
Photothermal elastic vibration spectra of SiO2 film on Si
(27th International Conference on Microelectronics, MIEL 2010 - Proceedings, 2010)
The silicon-dioxide film on the silicon substrate (SiO2/Si) samples were investigated by the photothermal elastic vibration method. The photothermal elastic vibrations in two-layer rectangular plates were optically excited ...
