A study of the photocatalytic degradation of metamitron in ZnO water suspensions
(Elsevier, Amsterdam, 2009)
The photocatalytic degradation of the herbicide metamitron in water using ZnO under Osram ULTRA-VITALUX (R) lamp light was studied. The effect of the operational parameters such as initial concentration of catalyst, initial ...
Real-time magnetic resonance imaging and quantification of lipoprotein metabolism in vivo using nanocrystals
(Nature Publishing Group, London, 2009)
Semiconductor quantum dots and superparamagnetic iron oxide nanocrystals have physical properties that are well suited for biomedical imaging. Previously, we have shown that iron oxide nanocrystals embedded within the lipid ...
Micelle and Vesicle Formation of Amphiphilic Nanoparticles
(Wiley-VCH Verlag Gmbh, Weinheim, 2009)
Determination of multiple pharmaceutical classes in surface and ground waters by liquid chromatography-ion trap-tandem mass spectrometry
(Elsevier Science Bv, Amsterdam, 2009)
This paper describes development, optimization and application of analytical method for determination and reliable confirmation of nineteen pharmaceuticals from different therapeutic classes (antibiotics-beta-lactams. ...
Enzymatic conversion of sunflower oil to biodiesel in a solvent-free system: Process optimization and the immobilized system stability
(Elsevier Sci Ltd, Oxford, 2009)
The feasibility of using the commercial immobilized lipase from Candida antarctica (Novozyme 435) to synthesize biodiesel from sunflower oil in a solvent-free system has been proved. Using methanol as an acyl acceptor and ...
Alumina/silica supported K2CO3 as a catalyst for biodiesel synthesis from sunflower oil
(Elsevier Sci Ltd, Oxford, 2009)
The new type of catalyst for fatty acid methyl esters (FAME or biodiesel) synthesis with K2CO3 as active component on alumina/silica support was synthesized using sol-gel method. Corresponding catalyst (xerogel) was prepared ...
Biodiesel synthesis at high pressure and temperature: Analysis of energy consumption on industrial scale
(Elsevier Sci Ltd, Oxford, 2009)
Analysis of several different schemes for industrial FAME production at higher pressure and temperature (catalytic or non-catalytic synthesis) was realized with the aim to find the best route to reduce the energy consumption ...
Authors' response to comments on "Factors influencing the removal of divalent cations by hydroxyapatite" Discussion
(Elsevier, Amsterdam, 2009)
Recently. it has come to our attention, that a polemical note by Milonjic [S.K. Milonjic, Comments on "factors influencing the removal of divalent cations by hydroxyapatite", J. Hazard. Mater. 162 (2009) 1588-1589]. has ...
Biologically active fibers based on chitosan-coated lyocell fibers
(Elsevier Sci Ltd, Oxford, 2009)
The possibilities of obtaining biologically active cell ulose-chitosan fibers were examined. An effective two-stage method was developed. The first stage involves the formation of dialdehyde cellulose by the potassium ...
Biosorption of heavy metal ions from aqueous solutions by short hemp fibers: Effect of chemical composition
(Elsevier Science Bv, Amsterdam, 2009)
Sorption potential of waste short hemp fibers for Pb2+, Cd2+ and Zn2+ ions from aqueous media was explored. In order to assess the influence of hemp fiber chemical composition on their heavy metals sorption potential, ...
