Phase transition at subcritical and supercritical conditions of triglycerides methanolysis
(Elsevier, Amsterdam, 2010)
The analysis of phase equilibrium between methanol and glycerides during methyl esters of fatty acids (FAME or biodiesel) synthesis at high pressure and temperature is very important for describing the kinetic and process ...
On the systematic design and selection of optimal working fluids for Organic Rankine Cycles
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
This work presents the first approach to the systematic design and selection of optimal working fluids for Organic Rankine Cycles (ORCs) based on computer aided molecular design (CAMD) and process optimization techniques. ...
Extraction of sage (Salvia officinalis L.) by supercritical CO2: Kinetic data, chemical composition and selectivity of diterpenes
(Elsevier Science Bv, Amsterdam, 2010)
The supercritical carbon dioxide (SFE) extraction of Dalmatian sage (Salvia officinalis L) was investigated and compared to extraction performed by Soxhlet ethanol-water (70:30) mixture extraction (SE) and hydrodistillation ...
Effect of fermentation on antioxidant properties of some cereals and pseudo cereals
(Elsevier Sci Ltd, Oxford, 2010)
The influence of fermentation by two types of microorganisms (lactic acid bacteria Lactobacillus rhamnosus, and yeast Saccharomyces cerevisiae) on antioxidant activities and total phenolics of 4 cereals, namely buckwheat, ...
Nonlinear Frequency Response of Electrochemical Methanol Oxidation Kinetics: A Theoretical Analysis
(Electrochemical Soc Inc, Pennington, 2010)
In this theoretical contribution, nonlinear frequency response analysis was applied for the investigation of electrochemical methanol oxidation. This technique expresses the input-output behavior of any weakly nonlinear ...
Determination of pesticides in surface and ground waters by liquid chromatography-electrospray-tandem mass spectrometry
(Elsevier, Amsterdam, 2010)
The sensitive multiresidual analytical method for simultaneous analysis of 14 most commonly used agricultural pesticides in Serbia was developed and optimized. The selected insecticides, fungicides and herbicides belong ...
The microwave-assisted synthesis of 5-arylazo-4,6-disubstituted-3-cyano-2-pyridone dyes
(Elsevier Sci Ltd, Oxford, 2010)
A novel protocol for the rapid synthesis of pyridone colorants under controlled microwave irradiation ill a dedicated reactor is described. Short reaction times, high isolated yields. and versatility for different substrates ...
Optimal conceptual design of processes with heterogeneous catalytic reactors
(Elsevier Science Sa, Lausanne, 2010)
This paper presents an optimisation-based method for the screening and conceptual design of processes with heterogeneous catalytic reactors. The method follows a multi-level approach to process synthesis to establish ...
Corrosion protection of aluminium pretreated by vinyltriethoxysilane in sodium chloride solution
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The corrosion protection of vinyltriethoxysilane (VTES) films on aluminium during exposure to 3% NaCl was investigated using electrochemical impedance spectroscopy (EIS), potential-time measurements and optical microscopy ...
The response of peritoneal macrophages to dapsone covalently attached on the surface of carbon nanotubes
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
Dapsone is an anti-microbial and anti-inflammatory drug. Water-dispersible dapsone-modified multi-wall carbon nanotubes (dap-MWCNTs) were prepared by chemical modification of the carboxyl groups introduced on the surface ...
