Magnetic effects in electrochemistry / Magnetni efekti u elektrohemiji
(Serbian Chemical Society, 2005)
The effect of imposed magnetic fields onto the electrodeposition of magnetic (nickel) and non – magnetic (copper) metals was analysed. Also, magnetic properties of electrochemically obtained nanocontacts were examined. An ...
Preparation and characterization of two types of covalently immobilized amyloglucosidase / Dobijanje i karakterizacija dva tipa imobilizovane amiloglukozidaze
(Serbian Chemical Soc, Belgrade, 2005)
Amyloglucosidase from A. niger was covalently immobilized onto poly( GMA-co-EGDMA) by the glutaraldehyde and periodate method. The immobilization of amyloglucosidase after periodate oxidation gave a preparate with the ...
Mechanically activated synthesis of CaTiO3 from mixture of CaO and TiO2
(Materials Science Forum, 2005)
Crystalline calcium titanate was synthesized by mechanical activation of a mixture of CaO, obtained by thermal treatment of CaCO3, and TiO 2 in anatase or rutile form, in a planetary ball mill for 30, 60, 120 and 240 min.. ...
Volatile Components from Old Plum Brandies / Hlapljivi sastojci šljivovice
(Croatia : University of Zagreb, 2005)
Gas chromatography and GC/MS methods were used to detect volatile components of three home-made natural old plum brandy samples and one sample of industrially-produced plum brandy. Gas chromatography and gas chromatography-mass ...
The effect of heterocyclic S,S’-ligands on the electrochemical properties of some cobalt(III) complexes in acid / Uticaj heterocikličnih S,S’-liganada na elektrohemijske osobine nekih kobalt(III) kompleksa u kiseloj sredini
(Serbian Chemical Society, 2005)
Eight mixed-ligand cobalt(III) complexes with the macrocyclic amine 1,4,8,11-tetraazacyclotetradecane (cyclam) and a heterocyclic dithiocarbamate (Rdtc-)i.e., morpholine-(Morphdtc), thiomorpholine- (Timdtc), piperazine-(Pzdtc), ...
Some aspects of nickel electrodeposition in the presence of a magnetic field / Neki aspekti taloženja nikla u prisustvu magnetnog polja
(Serbian Chemical Society, 2005)
Nickel deposits obtained from a Watt solution both without and with a perpendicularly oriented magnetic field were examined by scanning electron microscopy (SEM). The nickel deposit obtained without an imposed magnetic ...
Inhibition effects in the partial oxidation of cyclohexane on polymer supported Co(II) catalysts / Efekti inhibicije u parcijalnoj oksidaciji cikloheksana Co(II) katalizatorima nanetim na polimerni nosač
(Serbian Chemical Society, 2005)
Polymer supported catalysts with different contents of metal ions where synthesized by wet impregnation of the degassed support from ethanolic solutions of cobalt(II) nitrate. Amacroreticular copolymer of poly-4-vinylpyridine ...
Magnetic properties of ND Rich Melt-Spun ND-FE-B alloy
(International Institute for the Science of Sintering, Beograd, 2005)
As a part of these experimental investigations of melt-spun Nd-Fe-B alloy with Nd rich content in relation to Nd2Fe14B prepared by rapid quenching process for optimally selected cooling rate and heat treatment, the influence ...
Study of gold-platinum and platinum-gold surface modification and its influence on hydrogen evolution and oxygen reduction / Površinska modifikacija platine zlatom i zlata platinom i njen uticaj na reakcije izdvajanja vodonika i redukcije kiseonika
(Serbian Chemical Society, 2005)
Surface modification of the electrodes was conducted from sulfuric acid solutions containing the corresponding metal-chloride complexes using cyclic voltammeter. Comparing the charges of the hydrogen underpotential deposition ...
