Controlled swelling and degradation studies of alginate microbeads in dilute natrium citrate solutions / Ispitivanje mogućnosti kontrolisanog bubrenja i razgradnje alginatnih mikročestica u razblaženim rastvorima natrijum-citrata
(Association of Chemical Engineers of Serbia, 2010)
Alginate hydrogels are widely used in biomedicine due to alginate availability, hydrophilic nature, biocompatibility and biodegradability. Alginate microbeads are particularly attractive for applications in pharmacy and ...
A study of the catalytic role of a gold electrode in the electrochemical activation of four macrolide antibiotics in sodium bicarbonate solution / Ispitivanje katalitičke uloge elektrode od zlata u elektrohemijskoj aktivaciji četiri makrolidna antibiotika u natrijum-bikarbonatnom elektrolitu
(Association of the Chemical Engineers of Serbia, 2010)
Using the cyclic voltammetry, it has been shown that hydrogen evolution at a gold electrode is necessary in the electrochemical activation of azithromycin dihydrate and erythromycin A. After four hours of the potential ...
Pollutants and the water quality of the river Ralja: From the spring up to U.S. Steel Serbia d.o.o. / Zagađivači i kvalitet reke Ralje od izvora do U.S. Steel Serbia d.o.o.
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2010)
In the period from July to October 2009 the examination of the water and sediment quality of the river Ralja was carried out from the spring up to wastewater inflow from the US Steel Serbia industrial complex. Water and ...
New Hybrid Properties of TiO2 Nanoparticles Surface Modified With Catecholate Type Ligands
(Springer, New York, 2010)
Surface modification of nanocrystalline TiO2 particles (45 ) with bidentate benzene derivatives (catechol, pyrogallol, and gallic acid) was found to alter optical properties of nanoparticles. The formation of the inner-sphere ...
Electrochemical determination of glucose using polyaniline electrode modified by glucose oxidize
(Nice : International Society of Electrochemistry, 2010)
Polyaniline (PANI) enzyme electrode was formed by immobilization of Glucose oxidase (GOx) via glutaraldehyde into electrochemicaly polymerized PANI on graphite electrode. Electrochemical polymerization of PANI on graphite ...
Electrochemical characterization of polyaniline electrode for use in electrochemical power sources
(Nice : International Society of Electrochemistry, 2010)
Polyaniline (PANI) electrode was formed by electrochemical synthesis on graphite under galvanostatic condition at current density of 2.0 mA cm-2 from aqueous solution of 1.0 mol dm-3 HCl and 0.25 mol dm-3 aniline. ...
Analytical model of MIS structure in electron devices / Analitički model MIS strukture u elektronskim napravama
(Savez inženjera i tehničara Srbije, Beograd, 2010)
In this paper the new analytical model of MIS (Metal-Insulator -Semiconductor) structure, in microelectron devices, is proposed. Presented model is relatively simple and, at the same time, the results obtained by the ...
