Effect of surface activation of alumina particles on the performances of thermosetting-based composite materials
(Sage Publications Ltd, London, 2019)
Two types of alumina particles, commercial (c-Al2O3) and iron doped (Fe-Al2O3), were functionalized with 3-(aminopropyl)trimethoxysilane (one-step) and two-step consecutive process, i.e. firstly using 3-(aminopropyl)trim ...
PMMA-Y2O3 (Eu3+) nanocomposites: Optical and mechanical properties / Nanokompozit PMMA-Y2O3 (Eu3+) - optička i mehanička svojstva
(Serbian Chemical Society, Belgrade, 2011)
The results of a study related to the processing and characterization of poly(methyl methacrylate) (PMMA)-Y2O3 (Eu3+) nanocomposites are presented herein. The nanocomposite samples were prepared using a laboratory mixing ...
Influence of an accumulative roll bonding (ARB) process on the properties of AA5083 Al-Mg alloy sheets
(Association of Metallurgical Engineers of Serbia AMES, 2014)
In this study, fully annealed AA5083 type alloy sheets with 1 mm in thickness
were processed by accumulative roll bonding (ARB) at room temperature, up to 6 ARB
cycles. It was found that microstructure was refined and ...
Influence of compression speed and deformation percentage on mechanical properties of calcium alginate particles / Uticaj brzine kompresije i procenta deformacije na mehaničke karakteristike kalcijum alginatnih čestica
(Association of the Chemical Engineers of Serbia, 2015)
Hydrogel particles are often used as carriers for the immobilization of enzymes, polyphenolic antioxidants, whole microbial, plant or mammalian cells. In many processes, the mechanical properties of alginate particles are ...
Synthesis and characterization of semi-interpenetrating networks of chitosan and poly(N-vinyl-2-pyrrolidone) / Sinteza i karakterizacija semi-interpenetrirajućih mreža hitozana i poli(N-vinil-2-pirolidona)
(Association of Chemical Engineers of Serbia, 2010)
Semi-interpenetrating networks (semi-IPNs) based on chitosan and poly(N-vinyl-2-pyrrolidone) were prepared in order to achieve better mechanical properties. The samples were characterized by FTIR, SEM, DMA analysis and the ...
