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 ...
Behaviour of non-standard composition copper bearing anodes from the copper refining process
(Elsevier Science Bv, Amsterdam, 2010)
This paper addresses on investigation the possibility of electrolytic treatment the sulphur acidic waste solution, obtained in the conventional electrolytic copper refining process. Beside the high copper concentration, ...
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 ...

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 ...
Preparation of MEMO silane-coated SiO2 nanoparticles under high pressure of carbon dioxide and ethanol
(Elsevier, Amsterdam, 2010)
The objective of this study is to investigate and compare methods of nanosilica coating with gamma-methacryloxypropyltrimethoxy (MEMO) silane using supercritical carbon dioxide and carbon dioxide-ethanol mixture. ...
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 ...
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 ...
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 ...
