Relationship between the kinetic parameters and morphology of electrochemically deposited lead
(Serbian Chemical Society, 2016)
The processes of lead electrodeposition from electrolytes of various concentrations of sodium nitrate as the supporting electrolyte have been examined by chronoamperometry and by the scanning electron microscopic (SEM) ...
Phase composition of Bi2O3 specimens doped with Ti, Zr and Hf
(Belgrade : Serbian Chemical Society, 2012)
Powder mixtures of α-Bi2O3 containing 2, 5 and 10 mole % of TiO2, ZrO2 or HfO2 were homogenized, heated at 820ºC for 24 h and quenched in air. X-ray powder diffraction technique was used to characterize the prepared samples. ...
The current distribution in an electrochemical cell. Part VII. Concuding remarks
(Serbian Chemical Society, 2002)
A new method for the determination of the ability of an electrolyte to distrubute uniformly current density in an electrochemical cell is proposed. It is based on the comparison of the current in cells in which the electrode ...
Određivanje efektivnog koeficijenta difuzije prilikom sušenja uzoraka od gline / Calculation of the effective diffusion coefficient during the drying of clay samples
(Srpsko hemijsko društvo, Beograd, 2012)
Cilj ovog rada je da se na primeru dve opekarske gline sa različitih lokaliteta odredi efektivni koeficijenat difuzije na osnovu eksperimentalno snimljenih krivih sušenja. Razvijen je metod i napravljena su dva kompjuterska ...
On the kinetics of the hydrogen evolution reaction on Ni-MoOx composite catalysts in alkaline solutions
(Belgrade : Serbian Chemical Society, 2012)
MoO3 particles were co-deposited with Ni onto smooth or rough Ni supports from modified Watt’s baths of different compositions. Morphology and composition of the electrodeposits were characterized by means of cyclic ...
Reflection and structural characteristics of semi-bright and mirror bright nickel coatings
(Journal of the Serbian Chemical Society, 2002)
The reflection and structural characteristics of the nickel coatings obtained in the presence of a basic brightening addition agent only, and of both a basic and top brightening, addition agent arc examined. It is shown ...
The effect of reversing current deposition on the apparent density of electrolytic copper powder / Uticaj reversne struje na nasipnu masu pri elektrolitičkom taloženju bakarnog praha
(Serbian Chemical Society, 2002)
The possibility of depositing copper powders with different apparent density by changing the shape of reversing current wave is shown. The morphology and crystallinity of powder particles can be varied considerably by ...
An inverse gas chromatography study of the adsorption of organics on zeolite and zeolite/iron oxyhydroxide composite at the infinite and finite surface coverage / Примена инверзне гасне хроматографије при нултој и коначној прекривености за испитивање адсорпције органских мoлекула на зеолиту и композиту зеолита и гвожђе-оксихидроксида
(Serbian Chemical Society, 2024)
The surfaces of natural (NZ) and zeolite/iron oxyhydroxide composite (ZFe) samples were analysed by means of inverse gas chromatography (IGC) using the adsorption data of organic non-polar and polar probes, in the infinite ...
The influence of electroless plated chromium on printing properties of aluminum offset printing plate
(Journal of the Serbian Chemical Society, 2002)
A method for the improvement of the printing properties of offset printing forms is presented. Specimens of technical aluminum were electrochemically roughened and treated in different alkaline solutions of chromium chloride ...
To Professor Petar Pfendt, In calidum, et plurium retributivus memoriae: FTIR-ATR analysis of post stamps of the Principality of Serbia issued in 1866 and 1868 and their forgeries
(Journal of the Serbian Chemical Society, 2022)
In order to further define the potential use of FTIR-ATR spectroscopy, as a non-destructive and reliable technique, for the analysis of the characteristics of post stamps, certified originals of the Principality of Serbia ...
