Reflection and structural analyses of mirror-bright metal coatings
(Springer, 2004)
Reflection and structural analyses of different copper and zinc coatings were performed. The copper coatings were electrodeposited from a sulfate solution in the presence of thiourea, as well as in the presence of modified ...
Electrochemical water splitting on zeolite supported platinum clusters
(Ecole Polytechnique Montreal, Montreal, 2004)
Platinum was incorporated into the cavities of NaX zeolite by impregnation/thermal decomposition technique, using Pt(II)-
acetylacetonate in acetone as an impregnating solution. The platinum-to-zeolite weight ratio amounted ...
Sesquiterpene lactones, lignans and flavones of Centaurea affinis
(Oxford : Pergamon-Elsevier Science Ltd, 2004)
Aerial parts of Centaurea affinis Friv. were collected at Vlasina (east Serbia) in September 1998.
Kinetics of deep oxidation of n-hexane and toluene over Pt/Al2O3 catalysts: Platinum crystallite size effect
(Elsevier, 2004)
The kinetics of n-hexane and toluene complete oxidation has been studied over 0.12% Pt/Al 2 O 3 catalysts. Measurements were performed in an external recycle reactor. Reaction rates were measured as a function of temperature ...
Guaianolides from two subspecies of Amphoricarpos neumayeri from Montenegro
(Oxford : Pergamon-Elsevier Science Ltd, 2004)
Quantitative H-1 NMR measurements revealed Delta(11(13)) sesquiterpene gamma-lactones as the main constituents (greater than or equal to 1% per weight of dried plant material) in the crude extracts of the aerial parts of ...
Sesquiterpene lactones from Cicerbita alpina
(Oxford : Pergamon-Elsevier Science Ltd, 2004)
The roots of Cicerbita alpina (L.) Wallr. were collected from Mt. Komovi, Montenegro.
Stereoselective synthesis of (-)-cytoxazone and (+)-epi-cytoxazone
(Oxford : Pergamon-Elsevier Science Ltd, 2004)
Optically pure (-)-cytoxazone was synthesized, starting from methyl p-methoxycinnamate, in six steps and in 31%, overall yield. The required anti-aminoalcohol configuration was established by combining Sharpless asymmetric ...
The effect of benzoic acid on the corrosion and stabilisation of electrodeposited copper powder
(Elsevier, 2004)
One of the main concerns in the production of electrolytic copper powder is stabilisation. Nonstabilised powder has a large surface area exposed to the effects of oxygen and moisture from the air. This leads to oxidation ...
Investigation of SiO/sub 2/ film on Si substrate by photoacoustic method
(Institute of Electrical and Electronics Engineers (IEEE)IEEE, 2004)
The effect of SiO/sub 2/ film on Si substrata (SiO/sub 2//Si) was investigated by photoacoustic spectroscopy. The amplitude and phase spectra were measured and analyzed in dependence on the wavelength of excitation optical ...
Introduction of Pt and Pd Nanoclusters in Zeolite Cavities by Thermal Degradation of Acetylacetonates
(Trans Tech Publications, Switzerland, 2004)
Nanodispersed metallic clusters of platinum and palladium were incorporated into NaX
zeolite cavities by impregnation with acetone solution of corresponding acetylacetonates, solvent
evaporation and acetylacetonate ...
