The STM analysis of a silver mirror surface / STM analiza površine srebrnog ogledala
(Serbian Chemical Society, 2001)
In this work, the structure of a silver mirror surface was examined by the STM technique. It was shown that the structural characteristics which enable a high degree of mirror reflection from this surface, which is very ...
The effect of particle structure on apparent density of electrolytic copper powder / Uticaj strukture čestica na nasipnu masu elektrolitički dobijenog bakarnog praha
(Serbian Chemical Society, 2001)
The quantitative microstructural analysis and the sieve analysis of copper powder as well as the scanning electron microscopy analysis of the copper powders particles were performed. It was found that the structure of the ...
On the kinetics of the hydrogen evolution reaction on zinc in sulfate solutions
(Belgrade : Serbian Chemical Society, 2001)
The kinetics and mechanism of the hydrogen evolution reaction (her) were studied on zinc in 1.0 mol dm-3 Na2SO4 at 298 K, in the pH range 4.4 - 10. It was found that a combination of classical potentiostatic steady-state ...
The effect of the composition of the dispersing medium of oxide sols on the electrocatalytic activity of sol-gel obtained RuO2-TiO2/Ti anodes / Uticaj sastava disperzne sredine oksidnih solova na elektrokatalitičku aktivnost RuO2-TiO2/Ti anoda dobijenih sol-gel postupkom
(Serbian Chemical Society, 2001)
The influence of the addition of methanol, ethanol, 1-propanol and 2-propanol to the dispersing medium of a mixture of RuO2 and TiO2 sols on the electrochemically active surface area for proton exchange, as well as on the ...
The growth of sapphire single crystals
(Serbian Chemical Society, 2001)
Sapphire (Al2O3) single crystals were grown by the Czochralski technique both in air and argon atmospheres. The conditions for growing sapphire single crystals were calculated by using a combination of Reynolds and Grashof ...
Ion/surface collisions: An alternative to gas-phase collisional activation in mass spectrometry
(Serbian Chemical Society, 2001)
Collisions of ions at solid surfaces result in a number of phenomena, of which surface-induced dissociation (SID) is the most important. SID has been shown to be a viable alternative to collision-induced dissociation (CID) ...
Densification and crystallization behaviour of colloidal cordierite-type gels / Denzifikacija i kristalizacija koloidnih gelova kordijeritnog sastava
(Serbian Chemical Society, Belgrade, 2001)
Three cordierite-type gels were prepared from an aqueous solution of Mg(NO3)2, a boehmite sol and silica sols of very small particle sizes. The effect of varying the silica particle size on the crystallization and densification ...
Electrochemical properties and thermal stability of epoxy coatings electrodeposited on aluminium and modified aluminium surfaces / Elektrohemijske karakteristike i termička stabilnost epoksidnih kataforetskih prevlaka na aluminijumu i modifikovanim površinama aluminijuma
(Serbian Chemical Society, Belgrade, 2001)
The corrosion behavior of epoxy coatings electrodeposited on aluminum, as well as on electrochemically and chemically modified aluminum were investigated during exposure to 3 % NaCl. Electrochemical impedance spectroscopy ...
NMR analysis of 2-(2',3'-dihydro-1'H-inden-1'-yl)-1H-indene / NMR analiza 2-(2',3'-dihidro-1'H-inden-1'-il)-1H-indena
(Serbian Chemical Society, Belgrade, 2001)
1H, 13C and two dimensional NMR analyses were applied to determine the NMR parameters of 2-(2',3'-dihydro-1'H-inden-1'-yl)-1H-indene. The chemical shifts of all the H- and C-atoms, as well as the appropriate coupling ...
Alumina/silica aerogel with zinc chloride as an alkylation catalyst / Alumosilikatni aerogel sa cink-hloridom kao katalizator za reakcije alkilovanja
(Serbian Chemical Society, Belgrade, 2001)
The alumina/silica with zinc chloride aerogel alkylation catalyst was obtained using a one step sol-gel synthesis, and subsequent drying with supercritical carbon dioxide. The aerogel catalyst activity was found to be ...
