The kinetics of the partial dehydration of gibbsite to activated alumina in a reactor for pneumatic transport / Kinetika parcijalne dehidratacije gibsita u reaktoru sa pneumatskim transportom
(Serbian Chemical Society, 2001)
The dehydration kinetics of gibbsite to activated alumina was investigated at four different temperatures between 883 K and 943 K in a reactor for pneumatic transport in the dilute two phase flow regime. The first order ...
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 ...
Fine structural analysis of the fungal polysaccharide pullulan elaborated by Aureobasidium pullulans, CH-1 strain / Fina strukturna analiza fungalnog polisaharida pululana dobijenog pomoću Aureobasidium pullulans, soj CH-1
(Serbian Chemical Society, 2001)
The structure of pullulan, the extracellular α-D-glucan elaborated by the yeast-like fungus Aureobasidium pullulans, may be described as a linear α-D-glucan consisting of maltotriosyl repeat units connected terminally by ...
Lead distribution in water and its association with sediment constituents of the "Barje" lake (Leskovac, Yugoslavia) / Raspodela olova u vodi i njegova asocijacija sa elementima u sedimentu jezera "Barje" (Leskovac, Jugoslavija)
(Serbian Chemical Society, 2001)
The lead concentrations in the water of the "Barje" lake are presented for the years 1995 to 1998. Sequential extraction was applied to estimate the chemical association of lead in the sediments of the "Barje" lake. Several ...
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 ...
Characterization and corrosion properties of electrodeposited Ni-W alloys / Karakterizacija i korozione karakteristike elektrohemijski taložene legure Ni-W
(Serbian Chemical Society, 2001)
Ni-W alloys electrodeposited from citrate solution consist of three different phases, which are all present in high W-content alloys: a solid solution of W in a Ni matrix; an intermetallic compound Ni4W, as well as another ...
Carbon monoxide oxidation on bimetallic Ru/Au(111) surfaces / Оксидација CO на биметалним Ru/Au(111) површинама
(Belgrade : Serbian Chemical Society, 2001)
The electrochemical deposition of Ru on Au(111) was performed in 0.5 M H2SO4 + 10-4 M RuCl3. The obtained bimetallic Ru/Au(111) surfaces were characterised by cyclic voltammetry and in situ STM in 0.5 M H2SO4. The Ru deposit ...
Carbon monoxide oxidation on a Au(111) surface modified by spontaneously deposited Ru / Оксидација CO на Au(111) површини модификованој спонтано депонованим Ru
(Belgrade : Serbian Chemical Society, 2001)
The spontaneous deposition of Ru on Au(111) was performed in 10-3 M RuCl3-0.5 M H2SO4 solution. The obtained surface was characterized by STM under potential control in 0.5 M H2SO4 solution. The coverage of the Au(111) ...
Evidence of stability of sedimentary organic matter during bacterial desilicification of an oil shale / Dokaz o postojanosti sedimentne organske supstance pri bakterijskoj desilicifikaciji jednog uzorka bituminoznog škriljca
(Serbian Chemical Society, 2001)
Aleksinac oil shale organic matter appeared to remain unchanged, according to elemental, IR, P-GC and P-GC-MS analytical characterization, after exposure to Bacillus circulans-Jordan desilicification for 30 days. These ...
