The effect of the particle shape and structure on the flowability of electrolytic copper powder. IV. The internal structure of the powder particles
(Journal of the Serbian Chemical Society, 2004)
The structure of powder particles was analysed by considering their cross sections. It was shown that the structure of powder particles of nonsieved flowing powders is sufficiently dense to produce a continuous surface, ...
The growth of sapphire single crystals
(Serbian Chemical Society, 2001)
Sapphire (Al2O3) single crystals were grown by the Czochralski technique both in air and argon atmospheres. The conditions for growing sapphire single crystals were calculated by using a combination of Reynolds and Grashof ...
Modelling of cations retention in ion chromatography with methanesulfonic acid as eluent
(Savez hemijskih inženjera, Beograd, 2017)
The two retention models, the linear solvent strength model (LSS) and the quadratic relationship, in addition to artificial neural network (ANN) approach, were compared in their ability to predict the retention behaviour ...
Influence of material velocity on heat generation during linear welding stage of friction stir welding
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
The heat generated during friction stir welding process depends on plastic deformation of the material and friction between the tool and the material. In this work, heat generation is analysed with respect to the material ...
Gamma Radiation Absorption Characteristics of Concrete with Components of Different Type Materials
(Acta Physica Polonica A, 2010)
Nuclear facilities as nuclear power stations, nuclear research reactors, particle accelerators and linear accelerator in medical institution using concrete in building construction. The different type materials of the ...
Stability of Metal-Oxide Varistor Characteristics in Exploitation Conditions
(Acta Physica Polonica A, 2009)
Wide-spread use of metal-oxide varistors for non-linearity over-voltage protection results in a variety of possible working conditions. It is therefore essential to have a thorough insight into their reliability in various ...
Corrosion resistance of high pressure torsion obtained commercially pure titanium in acidic solution
(University of Osijek, Tech Fac, Slavonski Brod, 2017)
The enhancement of commercially pure titanium (cpTi) mechanical properties, which is required for its medical application, can be achieved by grain refinement obtained by severe plastic deformation. In addition to mechanical ...
Indene dimerization products / Proizvodi dimerizacije indena
(Serbian Chemical Society, Belgrade, 2002)
The reaction of 1H-indene (indene) in the presence of Friedel-Crafts acids was studied. As expected [M. Spiteller, J. Jovanović, Fuel 78(1999)1263] there were dimers and trimers in the product mixture together with higher ...
Influence of the type of electrolyte on the morphological and crystallographic characteristics of lead powder particles / Uticaj tipa elektrolita na morfološke i kristalografske karakteristike praškastih čestica olova
(Serbian Chemical Society, 2013)
Lead electrodeposition processes from basic (nitrate) and complex (acetate) electrolytes were mutually compared by scanning electron microscopy and X-ray diffraction investigation of the produced powder particles. The shape ...
Integrity assessment of bucket wheel excavator welded structures by using the single selection method
(University of Osijek, Tech Fac, Slavonski Brod, 2013)
In order to reduce the testing costs for structural welded joints and production losses due to excavator standstill, a new method for integrity and reliability assessment of welded joints during exploitation of bucket wheel ...
