Bisphenol a removal from aqueous solution using fine alpha-fe2o3 particles
(Savez inženjera metalurgije Srbije, Beograd, 2018)
Iron(III) oxide particles (alpha-Fe2O3) were obtained from ferrous chloride (FeCl3 center dot 6H(2)O) precursor using ammonium hydroxide as a precipitating agent and particles were calcined at 700 degrees C for 4 h. ...
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 ...
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 ...
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 ...
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 ...
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 ...
Recyclability of technology metals from E-waste: Case study of in and Ga recovery from magnetic fraction
(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 ...
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 ...
Influence of the Fe(III): Modified clinoptilolite on phosphorus leaching from different soil types / Uticaj Fe(III)- modifikovanog klinoptilolita na izluživanje fosfora iz različitih vrsta zemljišta
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
Influence of the iron(III)-modified clinoptilolite (FeCLI) on phosphorus leaching from two different Norwegian soil types (sand and clay loam soil) was studied using a column system at room temperature. FeCLI was used in ...
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 ...
