Improvement in cavitation resistance of poly (vinyl butyral) composite films with silica nanoparticles: A technical note
(Polymers & Polymer Composites, 2021)
In this study poly (vinyl butyral)/silica (PVB/SiO2) composite films were subjected to the cavitation process. The experiments were carried out with a 10 wt.% PVB solution in ethanol. Silica nanoparticles were added into ...
Preparation of floating polymer-valsartan delivery systems using supercritical CO2
(Journal of Polymer Research, 2021)
This study investigates pharmaceutical polymers (Soluplus((R)), HPMCAS, and Eudragit((R)) E100) and supercritical CO2-assisted process for preparation of floating valsartan delivery systems. Tested process (at pressure of ...
Multi-criteria ranking of organizational factors affecting the learning quality outcomes in elementary education in Serbia
(Journal of Business Economics and Management, 2021)
The research within this paper is motivated by the opinion that different organizational factors in primary education can have a stronger or weaker impact on the quality of the learning outcome. Organizational factors, ...
The subthermal potential of karstic groundwater of Kuaj-Beljanica region in Serbia estimated by the multivariate analysis
(Environmental Earth Sciences, 2021)
To define the potential uses of groundwater, a detailed hydrochemical analysis was carried out in the Kuaj-Beljanica Massif at seven locations, in the eastern part of the Republic of Serbia. The hydrogeochemical analysis ...
Sn-doped TiO2 nanotubular thin film for photocatalytic degradation of methyl orange dye
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
We fabricated Sn-doped TiO2 nanotubular film via annealing of anodized TiO2 nanotubes grown on F-SnO2 (FTO) glass. Annealing was carried out at 500 degrees C in ambient air. Anatase crystal structure was achieved with no ...
Amino-modified hollow alumina spheres: effective adsorbent for Cd2+, Pb2+, As(V), and diclofenac removal
(Environmental Science and Pollution Research, 2021)
A simple sol-gel method and external gelatinization method of hollow alumina spheres synthesis were developed in this study. The spheres were modified with polyethyleneimine (PEI) producing PEI-Al2O3 via (3-glycidyloxypr ...
Design of halloysite modification for improvement of mechanical properties of the epoxy based nanocomposites
(Polymer Composites, 2021)
In this study, halloysite nanotubes (HNT) were modified by: 3-glycidyloxypropyltrimethoxysilane (GLYMO), 3-aminopropyltrimethoxysilane (APTES), and 2,2-Bis[4-(glycidyloxy) phenyl] propane (DGEBA), and incorporated in the ...
Novel Magnetic Polymer/bentonite Composite: Characterization and Application for Re(VII) and W(VI) Adsorption
(Science of Sintering, 2021)
A novel magnetic polymer/bentonite composite was prepared by suspension copolymerization of glycidyl methacrylate and ethylene glycol dimethacrylate in the presence of magnetic bentonite (MB-PGME) and functionalized with ...
Electrochemical deposition and characterization of iridium oxide films on Ti2AlC support for oxygen evolution reaction
(Springer, New York, 2021)
Two types of iridium oxide films formed at the Ti-2 AlC substrate were investigated: (1) anodically electrodeposited iridium oxide film from the solution based on IrCl(3)xH(2)O; (2) iridium oxide film prepared by cycling ...
Safe-by-design gelatin-modified zinc oxide nanoparticles
(Journal of Nanoparticle Research, 2021)
We report an innovative low-cost wet precipitation synthesis method for gelatin-modified zinc oxide nanoparticles (GM ZnO NPs) at the interface between the gelatin hydrogel and aqueous electrolyte. Diffusion of ammonia ...
