Apparent enthalpies of activation for oxygen reduction at Pt3Co electrode in alkaline solution
(Progress in Advanced Materials and Processes: Proceedings of the Fifth Jugoslav Materials Research Society, YUCOMAT V, 2004)
Oxygen reduction (OR) at a Pt3Co alloy electrode has been examined in alkaline solutions of different pH's in the temperature range from 274 to 313 K. At all temperatures, two distinct E-log j rep-ions are observed. At low ...
Uticaj obrade niskotemperaturnom plazmom na bojenje konoplje / The influence of low-temperature plasma treatment on dyeing properties of hemp
(Savez inženjera i tehničara tekstilaca Srbije, Beograd, 2004)
Obrada niskotemperaturnom plazmom povećava brzinu iscrpljenja boje, završno iscrpljenje i intenzitet obojenja tkanine od konoplje. Poboljšanja posle obrade plazmom su izraženija kod bojenja bojom C.I. acid blue 113 nego ...
Estimation of elastic properties of a particulate polymer composite using a face-centered cubic FE model
(Elsevier, Amsterdam, 2004)
A three-dimensional (31)) finite element (FE) unit cell model is applied to studies on the elastic properties of ceramic spherical particle-polymer composite. In this model, hydroxyapatite particles (HAp) are assumed to ...

A laboratory furnace for obtaining crystals
(Int Union Crystallography, Chester, 2004)
A design for a modular device ('crystallization shelf') installed in a laboratory furnace is presented. The setup allows regulation and simultaneous crystallization tests of several substances at different temperature ...
Characterization of dispersion strengthened copper with 3wt%Al2O3 by mechanical alloying
(International Institute for the Science of Sintering, Beograd, 2004)
The copper matrix has been dispersion strengthened with 3wt.%Al2O3 by mechanical alloying. Commercial alumina powder with an average particle size of 0.75mm was used for alloying. The mechanical alloying process was performed ...
Preparation and properties of polymeric and composite bioresorbable barrier membranes
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
Bioresorbable barrier membranes have been widely used in dentistry and maxillofacial surgery. When the membranes are placed over bony defects and are closely adapted by the surrounding bone face, an environment that prevents ...
