Ternary NR/BR/SBR rubber blend nanocomposites
(Journal of Thermoplastic Composite Materials, 2018)
The goal of this work was to synthesize and characterize ternary rubber blends based on polyisoprene (natural rubber (NR)), polybutadiene rubber (BR), and styrene-butadiene rubber (SBR) (NR/BR/SBR = 25/25/50) reinforced ...
Thermographic properties of Eu3+- and Sm3+-doped Lu2O3 nanophosphor
(Journal of the Serbian Chemical Society, 2012)
Samples of Lu2O3:Eu3+ (3 at. % Eu) and Lu2O3:Sm3+ (1 at. % Sm), were prepared via the polymer complex solution method using poly(ethylene glycol) as the fuel and as nucleation agent for crystallization process. Knowing ...
Radiation-induced modification of dielectric relaxation spectra of polyolefins: polyethylenes vs. polypropylene
(Polymer Bulletin, 2014)
The molecular relaxation behaviour of polyolefins exposed to high-energy radiation has been investigated by dielectric loss (tan delta) analysis. Therefore, low-density polyethylene, high-density polyethylene (HDPE), and ...
Antimicrobial Activity of Hybrid Hydrogels Based on Poly(Vinylpyrrolidone) Containing Silver
(Hemijska industrija, 2010)
New hybrid hydrogels were prepared by radical copolymerization of 2-hydroxyethyl methacrylate, itaconic acid, poly(vinylpyrrolidone) and silver salt. FTIR spectroscopy has confirmed binding of silver particles in hydrogels. ...
Pore Geometry of Ceramic Device: the Key Factor of Drug Release Kinetics
(Science of Sintering, 2013)
Release kinetics of tigecycline, a potential antibiotic in treatment of osteomyelitis, from calcium hydroxyapatite (CHA), as one of the most important ceramic materials in bone tissue engineering, was investigated in this ...
Magnetic Properties of Mn-Doped Amorphous SiO2 Matrix
(Acta Physica Polonica A, 2011)
Samples of Mn-doped amorphous SiO2 matrix with manganese concentration 0.7 and 3 at.% have been prepared by a sol-gel method. Transmission electron microscopy analysis has shown that the samples contain agglomerates of ...
Sol-gel as a Method to Tailor the Magnetic Properties of Co1+yAl2-yO4
(Science of Sintering, 2013)
The magnetic properties of mesoscopic materials are modified by size and surface effects. We present a sol-gel method used to tailor these effects, and illustrate it on Co1+yAl2-yO4 spinel. Nanocomposites made of spinel ...
Room-Temperature Ferromagnetism in Zn-Mn-O, X-Ray Photoemission Surface Study
(Acta Physica Polonica A, 2011)
Room temperature ferromagnetic properties of Zn-Mn-O show evident dependence on manganese concentration and preparation conditions. We systematically studied series of samples with manganese concentration ranging from 0 ...
Effective valorisation of barley bran for simultaneous cellulase and beta-amylase production by Paenibacillus chitinolyticus CKS1: Statistical optimization and enzymes application
(Journal of the Serbian Chemical Society, 2017)
The agricultural raw industry generates large amounts of annually by-products that create disposal problems. Hitherto, there have been no reported papers about the simultaneous production of cellulase and beta-amylase from ...
