Polypyrrole as possible electrode materials for the aqueous-based rechargeable zinc batteries
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
Polypyrrole (PPy) thin film electrode was galvanostatically synthesized and characterized in 0.1 M HCI on graphite electrode as cathode materials for the aqueous-based rechargeable zinc batteries. The charge/discharge ...
Hysteretic behavior modeling of elastoplastic materials / Modeliranje histerezisnog ponašanja elastoplastičnih materijala
(Serbian Society of Mechanics & Mathematical Institute of the Serbian Academy of Sciences and Arts, Belgrade, 2008)
In the present paper the Preisach model of hysteresis is applied to model cyclic behavior of elasto-plastic material. Rate of loading and viscous effects will not be considered. The problem of axial loading of rectangular ...
The electrochemical behavior of erythromycin A on a gold electrode
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
The reactivity of erythromycin (pure) was investigated on a gold electrode in neutral electrolyte by cyclic voltammetry. The resulting structural changes were observed with HPLC and FTIR spectroscopy by analyzing the bulk ...
Thermal shock behavior of alumina based refractories: Comparison with the mechanical data and thermal stability behavior prediction
(Belgian Ceramic Soc, Mons, 2008)
The thermal shock behavior of a large grain size alumina based refractories were investigated both experimentally, using standard procedure of water quench test and using mathematical calculation method for determining the ...
Immobilization of lipase on sepabeads and its application in pentyl octanoate synthesis in a low aqueous system / Imobilizacija lipaze na komercijalni epoksidni nosač za sintezu pentil-oktanoata u mikrovodenom sistemu
(Faculty of Technology, Novi Sad, 2008)
The object of the study was to investigate the process conditions relevant for the pentyl octanoate production with the lipase from Candida rugosa immobilized on Sepabeads EC-EP carrier. This is an epoxide-containing ...
The Antifungal Activity of Corona Treated Polyamide and Polyester Fabrics Loaded with Silver Nanoparticles
(Astronomical Observatory, Belgrade, 2008)
This study is aimed to highlight the possibility of using the corona treatment for fiber surface activation that can facilitate the loading of silver nanoparticles from colloids onto the polyester and polyamide fabrics and ...
Double-layer bioactive glass coatings obtained by pulsed laser deposition
(Trans Tech Publications Ltd, Durnten-Zurich, 2008)
Pulsed laser deposition was used to obtain functionally graded bioactive glass coatings on titanium substrates. An UV KrF* (lambda=248 nm, tau gt 7 ns) excimer laser was used for the multi-pulse irradiation of the targets. ...
Membrane interactions of ternary phospholipid/cholesterol bilayers and encapsulation efficiencies of a RIP II protein
(Elsevier Science Bv, Amsterdam, 2008)
Membrane interactions of liposomes of ternary phospholipid/cholesterol bilayers are investigated. These interactions lead to discoidal deformations and regular aggregations and are strongly enhanced by the presence of ...
Extraction of hyperforin and adhyperforin from St. John's Wort (Hypericum perforatum L.) by supercritical carbon dioxide
(Elsevier, Amsterdam, 2008)
St. John's Wort (Hypericum perforatum L.) was extracted with supercritical carbon dioxide (SC CO2) under 10, 15 and 20 MPa and at 313 and 323 K. The influence Of SC CO2 density (400-800 kg/m(3)) was examined with respect ...
