Hydrometallurgical process for extraction of metals from electronic waste, Part I: Material characterization and process option selection
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Used electronic equipment became one of the fastest growing waste streams in the world. In the past two decades recycling of printed circuit boards (PCBs) has been based on pyrometallurgy, highly polluting recycling ...
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 ...
Effect of heating rate on precipitation of peak-aged Al-Li (8091) alloy: A quantitative approach
(Savez inženjera metalurgije Srbije, Beograd, 2010)
Samples of Al-Li (8091) alloy were solution treated at 540ºC for 30 min, water-quenched and continuously heated in oil at 0.05 and 0.1ºC/min rates, from room temperature to 190ºC when the peak hardness was achieved. Having ...
The analysis of the tribological properties of multiple strengthened nanocomposite of the Cu-Al2o3 system
(Savez inženjera metalurgije Srbije, Beograd, 2011)
This paper presents the results of examined tribological properties of the multiple strengthened nanocomposite Cu-Al2O3 system. Cu-Al2O3 composite powder was obtained by combination of the thermo-chemical procedure and ...
Modern steels: Transformation induced plasticity / Savremeni čelici - transformacijom izazvana plastičnost
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2011)
TRIP čelici danas zauzimaju značajno mesto u komercijaloj upotrebi u vozilima i konstrukcijama kod kojih je jedan od glavnih zahteva redukcija sopstvene težine. Optimalna kombinacija udela stabilisanog austenita i stepen ...
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 ...
Partitioning of cellulolytic activity in the polyethylene glycol/dextran two-phase systems / Raspodela celulolitičke aktivnosti u dvofaznim sistemima polietilenglikol/dekstran
(Faculty of Technology, Novi Sad, 2012)
This study is concerned with the partitioning of cellulolytic activity in the polyethylene glycol/dextran two-phase systems. In the system of 10% (w/w) polyethylene glycol 1500/5% (w/w) dextran 500,000/80% (w/w) crude ...
Quality assurance of storage tanks after in-service crack repairs / Osiguranje kvaliteta rezervoara u eksploataciji posle popravke prslina
(Society for Structural Integrity and Life, Institute for Material Testing, 2013)
According to the Pressure Equipment Directive (PED 97/23/EC) a new produced storage tank can be accepted on the market only if the required quality is proved. In this way the structural integrity might be at the requested ...
Efficiencies of different methods for determination of organophosphate pesticide residues in fermented wheat substrate / Efikasnost različitih metoda za određivanje ostataka organofosfata u fermentisanim uzorcima žita
(Institute of Pesticides and Environmental Protection, 2013)
In the present work, the efficiencies of three different sample preparation methods for GC/ MS determination of pirimiphos-methyl and chlorpyrifos-methyl residues in wheat (Triticum spelta) samples fermented by Lactobacillus ...
Finite element analysis of fracture resistance parameters for stationary semi-elliptical surface cracks in high strength steel / Analiza parametara otpornosti na lom metodom konačnih elemenata, kod stacionarnih polueliptičnih prslina u čeliku povišene čvrstoće
(Society for Structural Integrity and Life, Institute for Material Testing, 2015)
This study deals with numerical simulations based on elastic-plastic finite element method for nonlinear stress analyses on pre-cracked tensile specimens with high strength properties. The influence of crack geometry on ...
