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 ...
Competitive sorption of silver, zinc and copper ions on different types of sorbent / Komparativna sorpcija jona teških metala na različitim tipovima sorbenata
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2015)
In this master thesis the sorption of heavy metals on activated carbon and zeolite was analyzed. The chosen heavy metals (Ag+, Cu2+, Zn2+) have been analyzed separately and as a mixture in order to check their sorption ...
Optimization of the synthesis of n-alkyl and n,n-dialkyl thioureas from waste water containing ammonium thiocyanate
(Savez hemijskih inženjera, Beograd, 2015)
The optimized methods for N-alkyl and N,N-dialkyl substituted thioureas synthesis starting from ammonium thiocyanates, waste water constituent from the production of tetramethylthiuram monosulfide (TMTS), and alkyl amine, ...
Electrochemical decolorization of the Reactive Orange 16 dye using a dimensionally stable Ti/PtOx anode
(Srpsko hemijsko društvo, Beograd, 2015)
The electrochemical decolorization of Reactive Orange 16 in a chloride containing solution was studied using a dimensionally stable Ti/PtOx anode. Different reaction parameters, agitation speed, applied current, sodium ...
Energy integration of nitric acid production using Pinch methodology / Energetska integracija proizvodnje azotne kiseline primenom Pinch metodologije
(Association of Chemical Engineers of Serbia, 2015)
Pinch methodology was applied to the heat exchangers network (HEN) synthesis of nitric acid production. The integration is analyzed in two ways, and the results are presented as two different solutions: i) the first solution ...
Effect of tracers molecular weight on the release process from alginate microbeads / Uticaj molekulske mase trejserskih indikatora na kontrolisano otpuštanje iz alginatnih mikročestica
(Savez inženjera i tehničara Srbije, Beograd, 2015)
The aim of this paper is to obtain microbeads of natural polymers such as alginate and chitosan. These microbeads were used as potential carriers for the active ingredients so that in this study the diffusion of various ...
Application of exergy analysis in recycling streams / Primena eksergijske analize u reciklažnim tokovima
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
Materials for recycling always contain a certain degree of contamination. The presence of impurities i.e. contamination in the recycling streams causes a change in the composition of the original materials to recycle. As ...
Periodically operated CSTRs with simultaneous modulation of feed concentration and flow-rate- Nonlinear frequency response approach
(10th European Congress of Chemical Engineering (ECCE 10), Nice, France, 2015)
Possible improvements of chemical reactor performance through periodic modulation of one or more inputs have been investigated for several decades. In our previous investigations we have introduced the nonlinear frequency ...
Influence of the structure of multilayer thin Ni/Cu films on their mechanical properties and MEMS devices fabrication applications / Uticaj strukture višeslojnih tankih filmova nikla i bakra na njihova mehanička svojstva i primenu u izradi MEMS naprava
(Belgrade: ETRAN – Society for electronics, telecommunication, computing, automatics and nuclear engineering, 2015)
Multilayer Ni/Cu films were alternately electrochemically deposited on polycrystalline Cu substrate by dual-bath technique. Change of the parameters such as total film thickness, sublayer thickness and sublayer thickness ...
