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 ...
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 ...
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) ...
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 ...
Rietveld refinement of a chabazite-like aluminophosphate containing a [Ni(1,2-diaminoethane)(2)O-2](2-) complex bridge
(Elsevier, Amsterdam, 2001)
The crystal structure of a novel Ni-containing precursor to the molecular sieve AlPO4-34 (CHA framework type) has been determined in its as-synthesized form using high-resolution synchrotron powder diffraction data. One ...
Determination of activation energy for static recrystallization using multipass continuous cooling torsion test
(Springer-Verlag Berlin, Berlin, 2001)
Two microalloyed steels (Nb/Ti low carbon and V medium carbon) were tested by means of continuous cooling multipass tests on high temperature torsion tester, with aim to investigate the recrystallization kinetics. Multistage ...
Ispitivanje hromatografskog ponašanja nekih azo boja derivata piridona / Chromatographic behaviour of some azo dyes pyridone derivates
(Beograd : Srpsko hemijsko društvo, 2001)
Azo jedinjenja predstavijaju nejveéu grupu industrijskih boja, kako po broju, tako i po obimu proizvodje. Azo boje obavezno sardze azo grupu (-N=N-) vezanu za aromatican prsten. Primenjuju se u tekstilnoj industriji, ali ...
Methanol oxidation on an ink type electrode using Pt supported on high area carbons
(Pergamon-Elsevier Science Ltd, Oxford, 2001)
Methanol oxidation was investigated on the following Pt catalysts: bare Pt electrode, Pt covered by nafion (R) film, and pt catalysts supported on high area carbons in the form of an ink. The reaction was carried out using ...
Delamination detection in woven composite laminates with embedded optical fibers
(Wiley-VCH Verlag Gmbh, Weinheim, 2001)
Analysis of crack initiation by micromechanism of ductile fracture in structural steel / Analiza nastanka prsline mikromehanizmom žilavog loma u konstrukcionom čeliku
(Vojnotehnički institut, Beograd, 2001)
In the presented paper a micromechanical model based on a particular flow criterion of a porous solid has been applied. In this study crack initiation in the smooth specimen made of steel 22 NiMoCr 3 7 has been analyzed; ...
