The influence of mechanical activation of ceramic powders on the quality of casting coatings / Uticaj mehaničke aktivacije keramičkih prahova na kvalitet livačkih premaza
(Savez inženjera i tehničara Srbije, Beograd, 2011)
In order to increase the efficiency of coatings, the influence of mechanical activation has been studied by monitoring the changes of surface and energy state, the change of structure and properties of ceramic powders under ...
Vrednovanje intelektualne svojine
(Economics institute, Belgrade, 2011)
Intellectual Property Rights (IPRs) and Intangible Assets (IAs) can be highly valuable playing a key role in many fields of business, touching nearly all aspects of a company: products development, human capital, marketing ...
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 ...
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 ...
Analysis of forced periodic operations of non-isothermal CSTR with modulation of inlet concentration and temperature
(8th European Congress of Chemical Engineering (ECCE 2011), Berlin, Germany, 2011)
One way to achieve process intensification is to operate the process in a periodic way, in order to obtain better average performance compared to the optimal steady-state operation. The source of the possible improvement ...
New model of the Serbian economic development 2011-2020: Possibilities and limitations / Novi model privrednog razvoja Srbije 2011-2020. - mogućnosti i ograničenja
(Društvo ekonomista Beograda, Beograd, 2011)
In this paper the new model of the Serbian economic development are studied. Because of the very bad situation in Serbian economy, in the paper are studied economic conditions in the previous period. The role and place of ...
Microhardness analysis of thin metallic multilayer composite films on copper substrates
(University of Belgrade, Technical Faculty, Bor, 2011)
Composite systems of alternately electrodeposited nanocrystalline Ni and Cu films on cold-rolled polycrystalline copper substrates were fabricated. Highly-densified parallel interfaces which can give rise to high strength ...
