Optical properties CaWO4:Nd3+/PMMA composite layered structures
(Elsevier, Amsterdam, 2019)
In this article, we report characterization of the layered composite fabricated from Nd3+ doped calcium twigstate single crystal (CaWO4 :Nd3+) and poly(methyl methacrylate) - PMMA with various organic-inorganic interfaces: ...
The influence of synthesis conditions on the redox behaviour of LiFePO4 in aqueous solution
(Elsevier Science Sa, Lausanne, 2019)
To contribute to the knowledge on the influence of synthesis procedure on the intercalation kinetics of lithium ions into phospho-olivines, LiFePO4/C composite samples (LFPC) were synthesized in two ways, the first one in ...
Leaves of common urban tree species (Aesculus hippocastanum, Acer platanoides, Betula pendula and Tilia cordata) as a measure of particle and particle-bound pollution: a 4-year study
(Springer, Dordrecht, 2019)
Magnetic biomonitoring using tree leaves has been proven as a proxy for airborne particle matter (PM) pollution. Since the leaf entrapment of PM is species-specific, in this study, four tree species common in urban areas ...
Statistical modeling and optimization of ultrasound-assisted biodiesel production using various experimental designs / Statističko modelovanje i optimizacija proizvodnje biodizela u prisustvu ultrazvuka primenom različitih eksperimentalnih planova
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
The present study compares the performances of the regression models developed by the response surface methodology combined with the full factorial, Box-Behnken or face central composite designs applied for the ultrasound-assisted ...
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 ...
Defining the ideality of the protective masks by the mathematical modeling method / Određivanje idealnosti zaštitnih maski metodom matematičkog modelovanja
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2019)
Technical contradiction occurs when the system improves one parameter, which automatically causes the deterioration of some of its other parameters. In such a situation, instead of usual acceptance of the optimization of ...
Migration of cypermethrin to and through the PET containers and artificial neural network-based estimation of its emission
(Springer Verlag, 2019)
Nowadays, the extensive use of pesticides in crops production puts a significant challenge to minimize its side effects along with safe production, storage, and after-use treatment. This paper reports results related to ...
Thermal and rheological properties of unsaturated polyester resins-based composites
(Unsaturated Polyester Resins: Fundamentals, Design, Fabrication, and Applications, 2019)
Unsaturated polyester resins (UPR) are among the most commercially important thermosetting matrix materials for composites. This chapter summarizes the importance of the thermal and rheological properties of UPR. The ...
Supercritical co2 impregnation of gelatin-chitosan films with clove essential oil and characterization thereof
(Savez hemijskih inženjera, Beograd, 2019)
Supercritical CO2 impregnation process was used for the first time to fabricate biodegradable gelatin-chitosan (G/Ch) films containing dove oil (CO) for potential use in active food packaging. All the impregnations were ...
Contributions of impregnated silver nanoparticles to ideality increase of filtration material in human respiratory protection / Doprinos impregnisanih nanočestica srebra porastu idealnosti filtrirajućih sredstava respiratorne zaštite
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
A technical contradiction arises when within a system one parameter improves thus automatically causing another one to worsen. In a situation like this, instead of a usual acceptance of compromise which leads to optimization ...
