Micromechanical investigating of the critical parameter's influence on adhesive properties of porous EVA/PMMA polymer blends using finite element method
(Belgrade : Institute of Technical Sciences of SASA, 2016)
Multi-criteria analysis of synthesis methods for ni-based catalysts
(Inst Za Kovinske Materiale I In Tehnologie, Ljubjana, 2016)
Catalysts based on the Ni/Al2O3 system are used in a variety of catalytic processes. Catalysts are commonly synthesized through thermochemical routes (impregnation, precipitation, coprecipitation and others). The authors ...
Synthesis, Structure and Properties of Nickel-Iron-Tungsten Alloy Electrodeposits PART II: Effect of Microstructure on Hardness, Electrical and Magnetic Properties
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2016)
Nanostructured nickel-iron-tungsten alloys were produced by electrodeposition from an ammoniacal citrate bath. The tungsten content of the alloy ranged from 0.8 wt.% to 11 wt.%, and the crystal grain size of the FCC phase ...
Hydrometallurgical recovery of tin and lead from waste printed circuit boards (wpcbs): limitations and opportunities
(Croatian Metallurgical Soc, Zagreb, 2016)
In this paper, possibility for selective Pb and Sn recovery, using three different solutions of NaOH, HCl and HNO3, from WPCBs containing low concentrations of Pb and Sn is presented. According to obtained results, over ...
Walsh analysis - a convenient preprocessor for period detection in astronomy
(Astronomical Observatory Belgrade, 2016)
Walsh analysis is practically analogous to Fourier analysis, except that square wave is used instead of the sine one. It has one major advantage over Fourier - it can be performed much faster. This may seem of little ...
Nickel-based catalysts: Dependence of properties on nickel loading and modification with palladium
(Savez hemijskih inženjera, Beograd, 2016)
The aim of this study was comparative analysis of catalysts with 5 and 20 wt.% Ni loading, with and without Pd additive, and it included: determination of reduction degrees, investigation on microstructure by scanning ...
Antibacterial and antioxidant capacity of egg white hydrolysates screened from proteolysis-assisted high intensity ultrasound treatment
(Portugal : Proteomass, 2016)
The main purpose of this research was to investigate the effect of high-intensity ultrasound treatment on one-step proteolysis of egg white proteins (EWPs) using commercial food-grade protease Alcalase as well as evaluating ...
Structural and functional characterization of papain-assisted ultrasound pretreated egg white hydrolysis
(Portugal : Proteomass, 2016)
The main objective of this research is to quantitatively investigate the impact of high intensity
ultrasound waves generated by probe-type sonicator on the selected functional and structural properties of papainassisted ...
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 ...
One-step hydrothermal synthesis of photocatalytically active TiO2/carbon composite
(Society of Physical Chemists if Serbia, 2016)
TiO2/carbon composite (TiO2/HTC), synthesized by hydrothermal
carbonization, was characterized by thermogravimetric analysis, nitrogen
adsorption–desorption isotherms and X-ray diffraction. The possibility of
using ...
