Structural properties of carbon microspheres obtained by hydrothermal treatment of fructose / Strukturne osobine mikrosfera ugljenika dobijenih hidrotermičkim tretmanom fruktoze
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
A carbon-rich solid product has been synthesized by hydrothermal treatment from fructose with HNO3 at temperature of 140°C. The concentration of the precursor was changed in order to investigate how its change influences ...
Anti-tarnish silver alloys in system ag-cu-zn-si with the addition of aluminum
(Association of Metallurgical Engineers of Serbia AMES, 2018)
This paper presents investigations of aluminum addition influence on the corrosion characteristics of the sterling silver Ag-Cu-Zn-Si alloys. The procedure for obtaining Ag-Cu-Zn-Al-Si alloys in small ranges of predefined ...
Graphene reinforced hydroxyapatite biocomposite coatings obtained by electrophoretic deposition on titanium / Biokompozitne prevlake hidroksiapatita ojačane grafenom, dobijene elektroforetskim taloženjem na titanu
(Engineering Society for Corrosion, Belgrade, Serbia, 2018)
Fast ongoing research of graphene-based nanomaterials reveals that their exceptional properties could be utized for biomedical applications, especially in tissue engineering and drug delivery. Here, we summarized the results ...
Failures of Brass Condenser Tubes / Lomovi kondenzatorskih cevi od mesinga
(Institut za ispitivanje materijala, Beograd, 2016)
Causes of failure of brass condenser tubes (CuZn28Sn1) in a thermal power plant in Serbia are analysed. Results of testing by Fourier transformed infrared spectroscopy (FTIR) have indicated the presence of ammonia and ...
Inventive level as a basis for the assessment of scientific contribution of inventors / Inventivni nivo pronalaska kao osnov za procenu naučnog doprinosa pronalazača
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2019)
The history of invention reveals that the most important inventions were derived from experiments by which their authors contributed to the discovery of previously unknown natural phenomena. So the question arises as to ...
Immobilization of peroxidase from fresh horseradish extract for anthraquinone dye decolorization / Imobilizacija peroksidaze iz svežeg ekstrakta rena i primena u dekolorizaciji antrahinonskih boja
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
Synthetic dyes are used in all sectors of industry and represent a serious ecological problem. By the presence, anthraquinone dyes are right after the azo dyes. Unlike azo, anthraquinone dyes are considerably harder to ...

(Association of Metallurgical Engineers of Serbia, 2019)
This study presents the results of the theoretical assessment and a preliminary experimental investigation of technology metals (TM) recovery from magnetic fraction obtained after mechanical treatment of waste printed ...
LT - contradiction matrix / LT - matrica kontradiktornosti
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2021)
Altschuller's Contradiction Matrix and Bartini-Kuznetsov's LT - Table represent two different tools for solving inventive problems based on the same dialectical principle. It starts from the premise that there are ...
Tensile strength properties of hybrid magnetic composite materials / Zatezna čvrstoća hibridnih magnetnih kompozitnih materijala
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
The Nd-Fe-B-barium ferrite hybrid composite materials with epoxy matrix presented in this paper cover maximum energy product from 1 to 13 MGOe. Mixture of magnetic particles is responsible for high magnetic quality, while ...
The influence of Mg and Mn content on abnormal grain growth in AA5182 type alloys
(Savez inženjera metalurgije Srbije, Beograd, 2019)
The occurrence of abnormal grain growth (AGG) in AA5182 alloy during annealing imposes severe restrictions on processing parameters and deteriorates mechanical properties. In this work, we investigated the effect of chemical ...
