Povećanje preciznosti izrade 3D štampanih delova primenom iterativne metode
(Uniiverzitet u Beogradu - Mašinski fakultet, 2020)
Veoma veliki porast upotrebe 3D štampe u poslednje dve decenije posledica je niza benefita koje
ova proizvodna tehnologija nudi. U ovom radu analizirano je odstupanje geometrije štampanog modela u
odnosu na CAD model. ...
Analysis and interpretation of the micromechanical properties measurements of electrodeposited nickel coatings on different substrates.
(Belgrade : Academy of Criminalistic and Police Studies, 2020)
Fine-grained nickel coatings were electrodeposited by direct current (dc) regime
onto different substrates: polycrystalline cold-rolled copper, polycrystalline brass and single
crystal (100)-oriented silicon. These ...
Influence of mechanochemical activation of components on synthesis of cordierite ceramics for application in electronics / Uticaj mehanohemijske aktivacije komponenti na sintezu kordijeritne keramike za primenu u elektronici
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2020)
The properties of cordierite, 2MgO·2Al2O3·5SiO2, makes this ceramics nowadays an attractive
material, which can be used for various applications in electronics. As the sintering temperature of
cordierite is very high ...
Response Surface Methodology and Artificial Neural Network-Based Models for Predicting Roughness of Cu coatings
(Belgrade: ETRAN – Society for electronics, telecommunication, computing, automatics and nuclear angineering, 2020)
Copper coatings are produced on silicon wafer by electrodeposition (ED) in pulsating current (PC) regime. Electrodeposition was performed at various current density amplitudes in the range of 80−140 mA cm-2, frequency in ...
Application of graphene quantum dots in heavy metals and pesticides detection
(Szeged : University of Szeged, 2020)
Graphene Quantum Dots (GQDs) were produced using electrochemical oxidation of graphite rods. Obtained GQDs were gamma-irradiated in the presence of the N atoms source, ethylenediamine. Both structural and morphological ...
Implementacija aditivne proizvodnje u Lean koncept / Implementation of additive manufacturing in the lean concept
(Uniiverzitet u Beogradu - Mašinski fakultet, 2020)
U ovom radu prikazan je značaj aditivne proizvodnje u okviru Lean koncepta. Koncept definiše sedam
vrsta proizvodnog otpada, dok Lean proizvodnja podrazumeva uklanjanje tog otpada. Aditivna proizvodnja
ispunjava sve ...
Forced periodic reactor operation
(4th Indo-German Workshop on Advances in Materials, Reaction& Separation Processes, Berlin, Germany, 2020)
We used the nonlinear frequency response (NFR) method in order to identify forced periodic conditions under which the acetic acid anhydride hydrolysis (chosen as a test reaction) can be favorably performed in a CSTR. Based ...
Bacterial degradation of monocyclic aromatic compounds in kraft lignin
(Federation of European Microbiological Societies (FEMS), 2020)
The aim of this study is to investigate the biodegradation potential of mixed cell bacterial culture to biodegrade monocyclic aromatic compounds in kraft lignin.
Optimization of biodiesel production from waste cooking oil using waste-based CaO/Zeolite catalyst
(Belgrade : Materials Research Society of SerbiaBelgrade : Institute of Technical Sciences of SASA, 2020)
Lignite coal fly ash collected from Serbian thermal power plants was converted into value-added zeolite-like material using a Teflon-lined hydrothermal reactor in an alkali activation process at 150 ºC for 24 h. The obtained ...
