Effect of CO2 pre-treatment on scCO(2) extraction of natural material
(Elsevier Science Sa, Lausanne, 2012)
Pre-treatment of natural materials prior to their extraction strongly influences the efficiency of the process. Therefore, proper selection of pre-treatment method enables intensification of extraction process. Within this ...
Copper-Sulfate Pentahydrate as a Product of the Waste Sulfuric Acid Solution Treatment
(Springer, New York, 2012)
The aim of this study is synthesis of copper-sulfate pentahydrate from the waste sulfuric acid solution-mother liquor generated during the regeneration process of copper bleed solution. Copper is removed from the mother ...
Surfactant-modified clinoptilolite as a salicylate carrier, salicylate kinetic release and its antibacterial activity
(Elsevier Science Bv, Amsterdam, 2012)
The cationic surfactant benzalkonium chloride (BC) was used for modification of the natural clinoptilolite surface in order to prepare a suitable carrier for the salicylate anion. The salicylate-containing clinoptilolite ...
Preparation, characterization and mechanical properties of rare-earth-based nanocomposites
(University of Belgrade, Technical Faculty, Bor, 2012)
This study reports research related to different preparation methods and characterization of polymer nanocomposites for optical applications. The Eu-ion doped Gd2O3 nanophosphor powder with different nanoparticle content ...
Liquid velocity in a high-solids-loading three-phase external-loop airlift reactor
(Wiley-Blackwell, Hoboken, 2012)
BACKGROUND: Airlift reactors are of interest for many different processes, especially for three-phase systems. In this study the behavior of a high-loading three-phase external-loop airlift reactor was examined. In particular, ...
The inhibitory effect of oregano extract on the growth of Aspergillus spp. and on sterigmatocystin biosynthesis
(Elsevier, Amsterdam, 2012)
The aim of this study was to investigate the effect of oregano extract on the growth of Aspergillus species (Aspergillus niger, Aspergillus carbonarius, and Aspergillus wentii) isolated from food and biosynthesis of ...
The effect of lignin on the structure and characteristics of composite coatings electrodeposited on titanium
(Elsevier Science Sa, Lausanne, 2012)
Composite coatings based on lignin, obtained by electrophoretic deposition (EPD) on titanium, were investigated. The aim of this work was to produce hydroxyapatite/lignin (HAP/Lig) coatings on titanium and to investigate ...
The influence of calcium-carbonate and yeast extract addition on lactic acid fermentation of brewer's spent grain hydrolysate
(Elsevier Science Bv, Amsterdam, 2015)
Brewer's spent grain (BSG) is the major by-product of the brewing industry, representing around 85% of the total. by-products generated. In this study BSG hydrolysate was produced using optimal conditions. Hydrolysates ...
High pressure densities and derived thermodynamic properties for the (n-heptane plus n-octane plus ethanol) ternary system
(Academic Press Ltd- Elsevier Science Ltd, London, 2017)
The density of the ternary system (n-heptane + n-octane + ethanol) at temperatures from (293.15 to 373.15) K and at pressures from (0.1 to 40) MPa was experimentally determined at twelve compositions and the results are ...
Bioreactor validation and biocompatibility of Ag/poly(N-vinyl-2-pyrrolidone) hydrogel nanocomposites
(Elsevier Science Bv, Amsterdam, 2013)
Silver/poly(N-vinyl-2-pyrrolidone) (Ag/PVP) nanocomposites containing Ag nanoparticles at different concentrations were synthesized using gamma-irradiation. Cytotoxicity of the obtained nanocomposites was determined by MU ...
