Removal of copper(II) ion from aqueous solution by high-porosity activated carbon
(Water Research Commission, Pretoria, 2013)
The removal of copper(II) ion from aqueous solution by the granular activated carbon, obtained from hazelnut shells (ACHS) (Corylus avellana L. var. lunga istriana), was investigated. The ACHS was prepared from ground dried ...
The influence of the size and surface modification of TIO2 nanoparticles on the rheological properties of alkyd resin / Uticaj veličine nanočestica TIO2 i njihove površinske modifikacije na reološka svojstva alkidne smole
(Association of Chemical Engineers of Serbia, 2013)
Spherical TiO2 particles of different size were dispersed in alkyd resin based on soybean oil. Four samples of TiO2 particles were used, three commercial and one obtained by acid catalyzed hydrolysis of titanium ...
Electrospun Poly(vinylbutyral)/silica Composite Fibres for Impregnation of Aramid Fabrics
(Materiale Plastice, 2014)
The poly (vinyl butyral)/silica (PVB/SiO2) composite fibers were produced by the electrospinning process. The experiments were performed with the PVB solution in concentration of 10 wt.% where ethanol was used as the ...
Improvement of antioxidant properties of egg white protein enzymatic hydrolysates by membrane ultrafiltration
(Savez hemijskih inženjera, Beograd, 2016)
The production of bioactive peptides from egg white proteins (EWPs) and their separation are emerging areas with many new applications. The objective of this study was to compare antioxidant activity of three distinct EWP ...
