Modelling and optimization of supercritical CO2 extraction of St. John's Wort (Hypericum perforatum L.) using genetic algorithm
(Elsevier Science Bv, Amsterdam, 2012)
Modelling and optimization of the extraction of St. John's Wort using supercritical fluid is the subject of this study. Applying conservation of mass, two partial differential equations were written for solute concentration ...
Comparative Microhardness Analysis of Various Thin Metallic Multilayer Composite Films
(IEEE, New York, 2012)
Different composite systems of electrodeposited monolayered and multilayered thin metal films of Ni and Cu on cold-rolled copper substrates were made. Thin metal layers were deposited at narrow spacing of 300 nm and 150 ...
Lactic acid production on brewers' spent grain hydrolysate by lactobacillus Rhamnosus and Lactobacillus fermentum / Mlečno-kisela fermentacija hidrolizata pivskog tropa pomoću lactobacillus Rhamnosus i Lactobacillus fermentum
(Nacionalno društvo za procesnu tehniku i energetiku u poljoprivredi, Novi Sad, 2014)
Brewers' spent grain (BSG) is the major by-product of the brewing industry, representing around 85% of the total by-products generated. Per 100 L of beer produced 20 kg of brewer's spent grain are obtained. BSG is a ...
Investigation of copper-alginate microbeads as antimicrobial materials for potential biomedical applications
(Wiley-Blackwell, Hoboken, 2012)
Oxidized and Ethylenediamine-Functionalized Multi-Walled Carbon Nanotubes for the Separation of Low Concentration Arsenate from Water
(Taylor & Francis Inc, Philadelphia, 2013)
In this work multiwalled carbon nanotubes (MWCNTs) modified by oxidation (o-MWCNTs) and by aminofunctionalization (e-MWCNTs) were examined as potential adsorbents for arsenate removal from water. Adsorption characteristics ...
Properties and drug release profile of poly(N-isopropylacrylamide) microgels functionalized with maleic anhydride and alginate
(Springer, New York, 2013)
This study highlights the advantages of functionalized poly(N-isopropylacrylamide) (PNIPAAm) microgels over pure PNIPAAm microgels in terms of polymer network properties and drug release profiles. PNIPAAm network was ...
Influence of surface modified TiO2 nanoparticles by gallates on the properties of PMMA/TiO2 nanocomposites
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Nanocomposites based on poly(methyl methacrylate) (PMMA) and TiO2 nanoparticles were synthesized by in situ radical polymerization of MMA in solution. The surface of TiO2 nanoparticles was modified with four gallic acid ...
Integrated production of lactic acid and biomass on distillery stillage
(Springer, New York, 2013)
The possibilities of parallel lactic acid and biomass production in batch and fed-batch fermentation on distillery stillage from bioethanol production were studied. The highest lactic acid yield and productivity of 92.3 % ...
Solvent and Structural Effects on the UV-Vis Absorption Spectra of Some 4,6-Disubstituted-3-Cyano-2-Pyridones
(Springer/Plenum Publishers, New York, 2012)
A series of 4,6-disubstituted-3-cyano-2-pyridones was synthesized and their UV-Vis absorption spectra were recorded in the region 200-600 nm in the set of selected solvents. The effects of solvent dipolarity/polarizability ...
Effect of austempering temperature on cavitation behaviour of unalloyed ADI material
(Elsevier Science Inc, New York, 2013)
This paper provides an in-depth study and description of cavitation damage and microstructural changes in two types of unalloyed austempered ductile iron (ADI). ADI materials used were austempered at 300 and 400 degrees C ...
