Methods for monitoring of pesticide residues in water: current status and recent trends
(Iwa Publishing, London, 2012)
An overview of analytical methods currently used for the determination of pesticide residues in water samples is presented. As liquid chromatography and gas chromatography, coupled to mass spectrometry, are considered to ...
The kinetics of the hydrogen oxidation reaction on WC/Pt catalyst with low content of Pt nano-particles
(Elsevier Science Sa, Lausanne, 2012)
The catalytic activity of WC/Pt electrocatalysts towards hydrogen oxidation reaction (HOR) in acid solution was studied. Tungsten carbide (WC) prepared by polycondensation of resorcinol and formaldehyde in the presence of ...
Diffusion of drugs in hydrogels based on (meth)acrylates, poly(alkylene glycol) (meth)acrylates and itaconic acid / Difuzija lekova u hidrogelovima na bazi (met)akrilata, poli(alkilenglikol)-(met)akrilata i itakonske kiseline
(Association of Chemical Engineers of Serbia, 2012)
The aim of this paper is to propose equations for the diffusion of drugs for investigated drug/hydrogel systems using the parameters affecting the transport of drug through poly- (2-hydroxyethylmethacrylate/itaconic acid) ...
The substituent effects on the 13C chemical shifts of the azomethine carbon atom of N-(substituted phenyl)salicylaldimines / Efekat supstituenata na 13C hemijska pomeranja azometinskog ugljenika N-(supstituisani fenil)saliciladimina
(Serbian Chemical Society, Belgrade, 2012)
Hammett correlations between the 13C-NMR chemical shifts of the azomethine carbon atom and the corresponding substituent constants were established for thirteen Schiff bases. The successful correlation of the chemical ...
Bound states in continuum generated by point interaction and supersymmetric quantum mechanics
(World Scientific Publ Co Pte Ltd, Singapore, 2012)
Four-parameter family of point interactions represent all possible self-adjoint extensions of kinetic energy operator. We demonstrate a method for generating a bound state in the continuum of point interactions which relies ...
The effect of grain size on the biocompatibility, cell-materials interface, and mechanical properties of microwave-sintered bioceramics
(Wiley, Hoboken, 2012)
The effect of decreasing the grain size on the biocompatibility, cellmaterial interface, and mechanical properties of microwave-sintered monophase hydroxyapatite bioceramics was investigated in this study. A nanosized ...
Erythrocytes as a novel drug delivery systems: Current status, challenges and perspectives of medical applications / Eritrociti kao savremeni nosači lekovitih supstanci - trenutni status, izazovi i izgledi za primenu u medicini
(MOST ART d.o.o., Beograd, 2012)
The erythrocytes are the most abundant cellular components ( gt 99%) of blood in humans. Besides their well known physiological functions, they serve as a natural blood compartment participating in biodistribution, metabolism ...
Separation and determination of dimethylarsenate in natural waters / Razdvajanje i određivanje dimetilarsenata u prirodnim vodama
(Serbian Chemical Society, Belgrade, 2012)
A simple and efficient method for the separation and determination of dimethylarsenate DMAs(V) was developed in this work. Two resins, a strong base anion exchange (SBAE) resin and iron-oxide coated hybrid (HY) resin were ...
Effect of CO2 pre-treatment on scCO(2) extraction of natural material
(Elsevier Science Sa, Lausanne, 2012)
Pre-treatment of natural materials prior to their extraction strongly influences the efficiency of the process. Therefore, proper selection of pre-treatment method enables intensification of extraction process. Within this ...
