Effect of cooling rate on the microstructure and magnetic properties of melt spun Nd-Fe-B alloys
(Elsevier, 2003)
The results of X-ray analysis, Mossbauer spectroscopy and magnetic measurement for melt-spun Nd-Fe-B with low content Nd obtained by optimal selected cooling rate and heat treatment are presented to bring some new information ...
Light modulation utilizing photonic crystal-based photoelastic elements with dual built-in defect
(IEEE Computer Society, 2003)
In this paper we analyze optical modulation by stress-sensitive active elements based on photonic crystals utilizing photoelasticity effects. Our approach is to utilize thin film sensitive elements with photonic bandgap ...
Effect of temperature on the methanol oxidation at supported Pt and PtRu catalysts in alkaline solution
(Elsevier, 2003)
The effect of temperature on the kinetics of methanol oxidation on supported 47.5 wt% Pt, 54 and 33.5 wt% Pt/Ru catalysts was studied in 0.1 M NaOH at 295, 313 and 333 K using thin-film rotating disk electrode (RDE) method. ...
Methanol electrooxidation on supported Pt and Pt/Ru catalysts in alkaline solution / Oksidacija metanola na Pt i Pt/Ru nanokatalizatorima u alkalnoj sredini
(Tehnika - Novi materijali, 2003)
The kinetic of methanol oxidation on 47.5 wt% Pt and 54 wt% Pt/Ru catalysts supported on high surface area carbon are measured in 0.1 M NaOH at 295 K and 333 K. The catalysts used were characterized by using TEM and XRD ...
Correlation of osmotic coefficient data for ZnSO4(aq) at 25 degrees C by various thermodynamic models
(Springer, 2003)
The available literature data on the osmotic coefficient of ZnSO4(aq) at 25degreesC in the molality range from 0.1 to 4.3 mol-kg(-1) and new experimental data from 1.2 to 2.9 mol-kg(-1), at the same temperature, are ...

Determination of all pK(a) values of some di- and tri-carboxylic unsaturated and epoxy acids and their polylinear correlation with the carboxylic group atomic charges
(Scientific Reviews Ltd., 2003)
For a series of seven unsaturated and seven epoxy di- and tricarboxylic acids, pK(a)(a) values were determined potentiometrically in aqueous media at 25 degreesC and an ionic strength of 0.1 M (NaCl). The thermodynamic ...
Photopyropiezoelectric elastic bending method
(AIP Publishing, 2003)
A method of investigation of semiconductors and metal–semiconductor structures based on two techniques: The elastic bending technique and pyropiezoelectric (PPE) technique was presented. The method was demonstrated on a ...
Terrorism in the light of nonlinear sciences: Stoichiometric network analysis of the population processes / Terorizam u svetlu nelinearnih nauka - stehiometrijska mrežna analiza populacionih procesa
(Nauka, tehnika, bezbednost, 2003)
Terrorism is considered as a complex nonequilibrium dynamical system, and it is described with simple model. The model is tested by Stoichiometric Network Analysis. Stability/instability condition is determined. Dynamical ...
