Comparison of structural, textural and thermal characteristics of pure and acid treated bentonites from Aleksinac and Petrovac (Serbia)
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Bentonite samples collected from vicinity of Petrovac and Aleksinac were treated with different sulfuric acid molarities. Acid attack dissolved the octahedral sheets by interlayer and edge attack. The effects of the H2SO4 ...
The EIS investigation of powder polyester coatings on phosphated low carbon steel: The effect of NaNO2 in the phosphating bath
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The effect of different type of iron-phosphate coatings on corrosion stability and adhesion characteristic of top powder polyester coating on steel was investigated. Iron-phosphate coatings were deposited on steel in the ...
Electrochemical synthesis and characterization of polyaniline thin film and polyaniline powder
(Elsevier Science Sa, Lausanne, 2011)
The polyaniline thin film electrode and powder have been synthesized on graphite electrodes from 0.5 M hydrochloric acid solution under galvanostatic conditions. The water insoluble and acetone soluble polyaniline mass ...
Failure analysis of chain bracket / Analiza loma spojnice lanca
(Society for Structural Integrity and Life, Institute for Material Testing, 2011)
In spite of numerous and expensive research in the field of fatigue and fracture and regular control of end products, cracks occur every day in all fields of human activity. This paper describes failure analysis of chain ...
High-temperature deformation behaviour of Ti3Al-11Nb intermetallic
(Carl Hanser Verlag, Munich, 2011)
A mechanism of high-temperature plasticity has been studied in terms of stress exponent and activation energy for deformation. A Ti3Al-based intermetallic was processed by hot-rolling in the two-phase field to accomplish ...
Liquid-liquid phase equilibria in nicotine (aqueous) solutions
(Elsevier, Amsterdam, 2011)
Liquid-liquid equilibria were measured for solutions containing: (1) nicotine, and one of the solvents PEG 200 or ethyl-lactate, and the ionic liquid 1-ethyl-3-methylimidazolium ethyl sulphate (ECOENG 212 (R)); (2) a ...
Microstructure and corrosion behaviour of Zn-Co alloys deposited from three different plating baths / Mikrostruktura i koroziono ponašanje Zn-Co legura taloženih iz sulfatnog i hloridnih rastvora
(Serbian Chemical Society, Belgrade, 2011)
The effects of plating baths of different composition on the micro- structure and corrosion stability of Zn-Co alloy coatings were studied. Zn-Co alloys with the same Co content were deposited from chloride plating baths ...
SiC synthesis using domestic mineral resources
(University of Novi Sad, 2011)
The possibility of using domestic Mg-silicate (sepiolite, white) as Si source and novolac resin (as carbon source), for synthesis of fine β-SiC powder at relatively low temperatures (1673-1873 K), was demonstrated. Obtained ...
The analysis of forming PVB-SiO2 nanocomposite fibers by the electrospinning process / Analiza formiranja PVB-SiO2 nanokompozitnih vlakana pomoću elektrospining procesa
(Vojnotehnički institut, Beograd, 2011)
The poly (vinyl butyral)-silica (PVB-SiO2) nanofibers were obtained by the electrospinning process. The experiments were carried out with PVB solution in concentration of 10 wt.% where ethanol was used as the solvent. The ...
Structural properties of Co, Ni and Mo powders obtained by electrochemical deposition
(Savez inženjera metalurgije Srbije, Beograd, 2011)
Magnetic thin films based on iron group elements (Fe, Co, Ni) are currently used in computer's hard disk drives and in MEMS, whereas electrodeposition is a suitable method to obtain these materials. The powders of metals ...
