Novel Approach for Determination of Potentially Toxic Elements via ICP-OES in Aqueous Solutions of Building Materials with Industrial Byproduct Addition
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2019)
New global tendencies for waste materials reusing in building materials are imposing the request for improved performances of chemical analysis methods and the improvements of matrices used. A new method for optical emission ...
Optical properties and fluorescence of quantum dots CdSe/ZnS-PMMA composite films with interface modifications
(Elsevier Science Bv, Amsterdam, 2019)
Processing and characterization of polymer nanocomposites based on poly (methyl methacrylate) (PMMA) matrix with embedded core-shell CdSe/ZnS quantum dots (QD's) were presented in this work. The aim is to preserve the ...
Structure and Microstructure Characterization of the La2SrB10O19 Glass-ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2019)
The crystal structure of new lanthanum strontium borate glass-ceramics was refined by the Rietveld method. The results showed that La2SrB10O19 has the monoclinic crystal structure, space group C2 (No. 5) with a = 11.1170(6), ...
Size-dependent antibacterial properties of Ag nanoparticles supported by amino-functionalized poly(GMA-co-EGDMA) polymer
(Wiley, Hoboken, 2019)
Size-dependent antimicrobial ability of silver nanoparticles (Ag NPs) supported by amino-functionalized poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) (poly(GMA-co-EGDMA)) macroporous copolymer was tested ...
Theorems of the Alternative for Systems of Convex Inequalities
(Springer, Dordrecht, 2019)
Systems of convex inequalities in function spaces are considered. Solvability conditions are obtained in the form of a theorem of the alternative. We revisit some results from the literature where such theorems are incorrect. ...
Color stability of bulk-fill and universal composite restorations with dissimilar dentin replacement materials
(Wiley, Hoboken, 2019)
Objective To determine color changes in bulk-fill composite and universal composite restorations with dissimilar dentin replacement materials in extracted teeth after staining in red wine. Materials and Methods Cylindrical, ...
Cellulase production by Sinorhizobium meliloti strain 224 using waste tobacco as substrate Utilization of waste tobacco for cellulase production
(Springer, New York, 2019)
This study has investigated the valorization of waste tobacco, as lignocellulosic biomass, for cellulase production by rhizobium belonging to genus Sinorhizobium. For the first time, Sinorhizobium meliloti strain 224 was ...
In Vitro and In Vivo Biocompatibility of Novel Zwitterionic Poly(Beta Amino)Ester Hydrogels Based on Diacrylate and Glycine for Site-Specific Controlled Drug Release
(Wiley-VCH Verlag Gmbh, Weinheim, 2019)
New (beta-aminoester) hydrogels (PBAE) based on di(ethylene glycol)diacrylate and glycine are successfully synthesized and characterized for the first time in this work. PBAE macromers are obtained using Michael addition. ...
The significance of periodic parameters for ANN modeling of daily SO2 and NOx concentrations: A case study of Belgrade, Serbia
(Turkish Natl Committee Air Pollution Res & Control-Tuncap, Buca, 2019)
In recent decades, artificial neural networks (ANNs) have been used for the prediction of concentration of air pollutants in urban areas. Beside meteorological variables, periodic parameters, such as hour of the day or ...
Non-thermal plasma and ultrasound-assisted open lactic acid fermentation of distillery stillage
(Springer Heidelberg, Heidelberg, 2019)
Stillage is the main by-product of bioethanol production and the cost of its treatment significantly affects the economy of bioethanol production. A process of thermal sterilization before lactic acid fermentation (LAF) ...
