Polyimide structures for micro-electro-mechanical system (mems) - based applications. / Polimidne konzole za primenu u mikro-elektro-mehaničkim (mems) sistemima
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2016)
This Ph.D. thesis studies and experimentally examines applicability of thin polymer films as structural substitutes for crystaline Si in bimorph MEMS structures. The two shapes (bi - morph) and transient state between the ...
Pt supported on nano-tungsten carbide as a beneficial catalyst for the oxygen reduction reaction in alkaline solution
(Elsevier, 2012)
Platinum nanocatalyst at nano-tungsten carbide was synthesized, characterized and tested for oxygen reduction reaction (ORR) in 0.1 mol dm−3 NaOH, at 25 °C. Tungsten-carbide islands on nano-tungsten particles (WC) was ...
Surface optical phonon (SOP) mode in ZnS/Poly (methylmethacrylate) nanocomposites
(Elsevier, Amsterdam, 2020)
The polymer nanocomposite ZnS/Poly (methylmethacrylate) was prepared by the solution casting method and its structural and optical properties were investigated using XRD, SEM, TEM, HRTEM, and Raman spectroscopy. The basic ...
Micromechanical analysis of fatigue and crack growth in carbon-fiber epoxy composites based on mechanical testing
(Savez hemijskih inženjera, Beograd, 2020)
The paper presents static and dynamic tests of carbon/epoxy composite materials with fiber orientation at 0 degrees/90 degrees and +/- 45 degrees. The main tensile properties were determined as a basis for subsequent dynamic ...
Thermal treatment of composite wastes for energy recovery / Termički tretman otpadnih kompozitnih materijala u cilju dobijanja energije
(Engineering Society for Corrosion, Belgrade, Serbia, 2020)
The expression waste-to-energy technologies is increasingly being used regarding waste reduction and utilization. Waste-to-energy technologies are procedures used to generate different forms of energy starting from a waste ...
Effect of solution pH on crack initiation and propagation in glass-polyester pipes subjected to impact
(Wiley-Blackwell, Hoboken, 2012)
The objective of this study was the determination of the influence of alkaline and acidic solutions on the impact properties of glass-polyester composite pipes. First, the impact test was performed on virgin samples (without ...
Estimation of GHG emission in Serbia for period 1995-2013 using recurent neural networks / Emisije gasova staklene bašte u Srbiji za period 1995-2013. godina primenom rekurentnih neuronskih mreža
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2015)
The aim of this work was to create an ANN model for the prediction of GHG emissions in the Republic of Serbia in the period 1995-2013. Because of the lack of GHG emission data and inputs for Serbia, the ANN model was ...
Leaching of chalcopyrite concentrate by hydrogen peroxide in sulphuric acid solution / Luženje halkopiritnog koncentrata rastvorom sumporne kiseline i vodonik-peroksida
(Savez inženjera i tehničara Srbije, Beograd, 2019)
Due to complex mineralogy and/or low content of base metals, some ores and mineral concentrates are not suitable for pyrometallurgical treatment. Therefore, those ores and concentrates have to be treated by application of ...
