Supercritical fluid extraction of curry flowers, sage leaves, and their mixture
(Elsevier, Amsterdam, 2013)
Yield and composition of curry flower (Helichrysum italicum) and sage leaves (Salvia officinalis) extract obtained by supercritical CO2 extraction (SFE) at 15 MPa and 40 degrees C were analyzed and compared to composition ...
Al-Cd Alloy Formation by Aluminum Underpotential Deposition from AlCl3+NaCl Melts on Cadmium Substrate
(Springer, New York, 2013)
Aluminum was incorporated into a polycrystalline cadmium electrode surface by underpotential deposition from equimolar AlCl3+ NaCl melt at 473 K, 523 K, and 573 K (200 A degrees C, 250 A degrees C, and 300 A degrees C). ...
Modelling of dissolved oxygen content using artificial neural networks: Danube River, North Serbia, case study
(Springer Heidelberg, Heidelberg, 2013)
The aims of this study are to create an artificial neural network (ANN) model using non-specific water quality parameters and to examine the accuracy of three different ANN architectures: General Regression Neural Network ...
Functionalization of textile materials with silver nanoparticles
(Springer, New York, 2013)
Nanoparticles gained much scientific attention in the past decade due to their specific surface chemistry and properties which are significantly different from that of the corresponding bulk materials. Silver nanoparticles ...

Suitability of some selected maize hybrids from Serbia for the production of bioethanol and dried distillers' grains with solubles
(Wiley, Hoboken, 2013)
BACKGROUND: Bioethanol is mostly produced from starchy parts of the corn grain kernel leaving significant amounts of valuable by-products such as dried distillers' grains with solubles (DDGS) which can be used as a substitute ...
In situ generation of Ag nanoparticles on polyester fabrics by photoreduction using TiO2 nanoparticles
(Springer, New York, 2013)
