Antioxidant and dietary products: Between truth and misconception
(Serbian Nutrition Society, 2021)
Almost all dietary products (dietary supplements, food for special medical purposes,…)
has a note saying that it contains antioxidants as an indispensable indication of its quality. This has become such a common practice ...
Stability of waste-based zeolite supported CaO catalyst for biodiesel production from waste oily feedstocks
(Fuel Science Center, 2021)
Waste-based zeolite supported CaO catalyst (20CaO/ZMFA) was synthesized by ultrasound-assisted impregnation from alcoholic suspension. Zeolite was previously synthesized from lignite coal fly ash (FA) by alkali activation ...
Proučavanje ravnoteža u heterogenim sistemima tricikličnog antidepresiva amitriptilina / Study of equilibria in heterogeneous systems of tricyclic antidepressant amitriptyline
(Belgrade : Serbian Chemical Society, 2022)
Cilj ovog rada bio je proučavanje ravnoteža u heterogenim sistemima tricikličnog
antidepresiva amitriptilina (Am) koji sadrže hloride i/ili fosfate. Rastvorljivost Am u
uslovima povećane jonske sile određena je pH–Ramp ...
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

Fractal Reconstruction of Fiber-reinforced Epoxy Microstructure
(Institute of Electrical and Electronics Engineers Inc., 2021)
In the past century, the use of polymers and composites with a polymer matrix has expanded to such a level that today it is impossible to imagine life without these materials. Epoxy resin and epoxy-based composites are ...
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 ...
Electrodeposition of Nd and Pr onto W from fluoride based melts / Elektrohemijsko taloženje Nd i Pr na W iz fluoridnih rastopa
(Belgrade : Serbian Society of Corrosion and Materials Protection (UISKOZAM), 2021)
Electrodeposition of neodymium and praseodymium metal from molten NdF3+PrF3+LiF+ 0.5wt.%Pr6O11+0.5wt.%Nd2O3 electrolytes on W was investigated using voltammetry at 1050 °C. The square wave voltammetry confirmed that Nd ...
