Supercritical carbon dioxide extraction of antioxidant fractions from selected Lamiaceae herbs and their antioxidant capacity
(Elsevier Sci Ltd, Oxford, 2010)
Antioxidant fractions from four herb spices belonging to the Lamiaceae family: rosemary (Rosmarinus officinalis), sage (Salvia officinalis), thyme (Thymus vulgaris) and hyssop (Hyssop officinalis) were isolated using ...
Adsorption-desorption noise in plasmonic chemical/biological sensors for multiple analyte environment
(Springer Heidelberg, Heidelberg, 2010)
We investigated intrinsic noise in plasmonic sensors caused by adsorption and desorption of gaseous analytes on the sensor surface. We analyzed a general situation when there is a larger number of different analyte species. ...

Nine compounds were detected in three different millipede species: Polydesmus complanatus (L.), Brachydesmus (Stylobrachydesmus) avalae A dagger uriA double dagger & Makarov, and Brachydesmus (Stylobrachydesmus) dadayi ...
Preparation and Characterization of Al2O3 Thin Films for Catalytic Activity Studies
(Nanostructured Materials, Thin Films and Hard Coatings For Advanced Applications, 2010)
In the present work, the surface properties of various Al oxide films were investigated. The oxide films were produced on a stainless steel by spray pyrolysis and cathodic deposition methods. The films obtained represent ...
Evaluation of heavy metal contamination in sediments using the method of total digestion and determination of the binding forms-Tisa River Basin, Serbia
(Taylor and Francis Inc., 2010)
This paper describes an approach for the evaluation of metal contamination in sediment, using the determination of binding forms of elements (sequential extraction method), the total element content (digestion method), as ...
Design of symmetric planar fishnet metamaterials for optical wavelength range
(27th International Conference on Microelectronics, MIEL 2010 - Proceedings, 2010)
In this work we analyze fishnet-type optical metamaterials with full electromagnetic symmetry, fabricated in an ultrathin, freestanding film (self-supported nanomembrane). We utilized the finite element method to simulate ...
Oxygen Reduction on Polycrystalline Pt Electrode Modified by Acetonitrile in Neutral Electrolyte
(Nice : International Society of Electrochemistry, 2010)
Oxygcn reduction was studied on pure polyclrystalline PI electrode and on one modified by chemisorbed acetonitrile in neutral solutions containing sulphate or chloride anions. Measurements were performed on polycrystalline ...
The electrochemical reduction of trinitrotoluene on a platinum wire modified by chemisorbed acetonitrile
(Elsevier, 2010)
The electrochemical reduction of 2,4,6-trinitrotoluene (TNT) was investigated by cyclic voltammetry on a platinum electrode in aqueous sodium chloride solutions with acetonitrile containing different concentrations of TNT. ...
AC Impedance tracking of glassy carbon activation
(Serbian Chemical Society, Belgrade, 2010)
Carbon materials, due to their physical and chemical properties, have found wide application in different electrochemical systems. They are often used as substrates for supercapacitors and different types of electrocatalysts. ...
