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 ...
Dithiophenes and other constituents of roots of Centaurea nicolai
(Oxford : Pergamon-Elsevier Science Ltd, 2003)
Centaurea nicolai Bald. is an endemic species found in the Mediterranean part of Montenegro, and in Albania. Roots of C. nicolai were collected on the south slopes of mountain Rumija on the Adriatic coast of Montenegro.
D(2) dopaminergic and 5-HT(1A) serotonergic activity of 2-(1-naphthyl)ethyl- and 2-(2-naphthyl)ethyl amines
(Wiley-Blackwell, Malden, 2003)
Several tertiary 2-phenylethyl, 2-(1-naphthyl)ethyl and 2-(2-naphthyl)ethyl amines were synthesized and their binding affinities for dopamine D(1), D(2) and serotonin 5-HT(1A) receptors evaluated in radioligand binding ...
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. ...
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 ...
A new class of electromagnetically coupled printed antenna arrays
(IEEE Computer Society, 2003)
A new class of electromagnetically coupled microwave printed antenna arrays using three coplanar strip-TCS (CPW with finite narrow ground strips) is reported. Two versions of this antenna array are introduced. (1) Antenna ...
A new type of slow-wave PBG microstrip ring resonator
(IEEE Computer Society, 2003)
A new type of microstrip ring resonator is introduced. In order to minimized dimensions the ring resonator is constructed like a PBG structure. The central frequency is 50% lower than in the conventional case. Additional ...
