Isopiestic determination of the osmotic and activity coefficients of the {yKBr + (1-y)K2HPO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2013)
The molality-based osmotic coefficients of aqueous mixtures of KBr and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic method at KBr ionic strength fractions y = (0.18328, 0.38241, 0.58031, 0.79186, ...
The influence of Ce-based coatings as pretreatments on corrosion stability of top powder polyester coating on AA6060
(Elsevier Science Sa, Lausanne, 2013)
Cerium-based conversion coatings (CeCCs) are one of the most prospective alternatives to the widely used chromate conversion coatings (CCCs) due to their anticorrosion efficiency, environmentally friendly nature and low ...
Hardwood lignin pyrolysis in the presence of nano-oxide particles embedded onto natural clinoptilolite
(Elsevier Science Bv, Amsterdam, 2013)
In this study the catalytic activity of Na-rich and MO-containing natural clinoptilolite (MO - nanopartides of NiO, ZnO, or Cu2O) was studied in the pyrolysis of hardwood lignin. The clinoptilolite samples exhibit different ...
Evaluation of periodic processes with two modulated inputs based on nonlinear frequency response analysis. Case study: CSTR with modulation of the inlet concentration and flow-rate
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
In our previous work, a new, fast and easy, nonlinear frequency response method for analysing potential improvements of reactor performance by forced periodic operation was presented. This method, which is based on Volterra ...
Conventional and spark-plasma sintering of cordierite powders synthesized by sol-gel methods
(Elsevier Sci Ltd, Oxford, 2013)
Cordierite powders synthesized by colloidal and alkoxide sol-gel methods were conventionally and spark-plasma sintered. The powders for the sintering investigations were obtained by calcination of the gels at a temperature ...
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)
This study discusses the possibility of in situ generation of Ag nanoparticles on polyester fabric by photoreduction of Ag+ ions with deposited TiO2 nanoparticles in the presence of amino acid alanine and methyl alcohol. ...
Characterization of PCBs from computers and mobile phones, and the proposal of newly developed materials for substitution of gold, lead and arsenic
(Springer Heidelberg, Heidelberg, 2013)
In this paper, we have analyzed parts of printed circuit board (PCB) and liquid crystal display (LCD) screens of mobile phones and computers, quantitative and qualitative chemical compositions of individual components, and ...
Forecasting human exposure to PM10 at the national level using an artificial neural network approach
(Wiley, Hoboken, 2013)
A neural network model for predicting country-level concentrations of the fraction of particulates in the air with sizes less than 10 mu m (PM10) has been developed using widely available sustainability and economical/industrial ...
Behavior of the surviving population of Lactobacillus plantarum 564 upon the application of pulsed electric fields
(Elsevier Sci Ltd, Oxford, 2013)
The behavior of the surviving population of Lactobacillus plantarum 564 growing in MRS broth after pulsed electric field (PEF) treatments of different intensities was monitored by isothermal calorimetry, optical density ...
