Production of lactic acid on liquid distillery stillage / Proizvodnja mlečne kiseline na tečnoj destilerijskoj džibri
(Nacionalno društvo za procesnu tehniku i energetiku u poljoprivredi, Novi Sad, 2011)
Bioethanol produced by fermentation of biomass is one of the most important renewable and ecologically friendly energy resources today. After bioethanol distillation a considerable amount of liquid stillage remains (1 hl ...
Titanium dioxide nanoparticles surface modified with imine as fillers for epoxy resin / Nanočestice titan-dioksida površinski modifikovane iminom kao punioci za epoksidnu smolu
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2018)
The surface of anatase TiO2 nanoparticles was modified with in situ synthesized imine, based on 3,4-dihydroxybenzaldehyde and octadecylamine. The modified TiO2 nanoparticles were investigated using FTIR and UV-Vis spectroscopy, ...
Mechanical properties and microstructure of molybdenum coating layers deposited vacuum plasma spray process / Mehanička svojstva i mikrostruktura slojeva prevlake molibdena deponovane vakuum plazma sprej procesom
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
Molybdenum coatings due to their excellent wear resistant properties and sliding characteristics under dry friction conditions are often used in applications to resist friction and dry sliding. Since molybdenum metal is ...
Analysis of metal ion release from biomedical implants
(Association of Metallurgical Engineers of Serbia, 2013)
Metallic biomaterials are commonly used for fixation or replacement of damaged bones in the human body due to their good combination of mechanical properties. The disadvantage of metals as implant materials is their ...
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 ...
Quality, sources and balancing of iron and steel scrap / Kvalitet, izvori i bilansiranje otpadaka gvožđa i čelika
(Savez inženjera i tehničara Srbije, Beograd, 2015)
Besides iron ore, the main raw material of iron and steel production is steel scrap. This paper presents the quality and sources of creation the iron and steel scrap and estimation of their creation in the future. The ...
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 ...
