Crystal structure of 2-{1-[(1-(2-pyridinio)ethylidene)hydrazono]ethyl} pyridinium diperchlorate, the product of template condensation in the presence of Cr(III)
(Journal of Chemical Crystallography, 2009)
In an attempt to synthesize a Cr(III) complex of 2′-[1-(2-pyridinyl) ethylidene]oxamohydrazide an azine product 2-{1-[(1-(2-pyridinio)ethylidene) hydrazono]ethyl}pyridinium diperchlorate was obtained by an electrophilic ...
Composition and antibacterial activity of Achillea asplenifolia essential oil
(Allured Publ Corp, Carol Stream, 2002)
The oil of a wild growing population of Achillea asplenifolia Vent. was studied for yield, composition and antibacterial activity. The major components in the oil were beta-caryophyllene (17.6%), germacrene D (15.6%) and ...
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.
Synthesis, characterization and biological activity evaluation of novel Pd(II) and Pt(II) complexes with heterocyclic hydrazone ligands
(Materials Science Forum, 2007)
New complexes of Pt(II) with condensation derivatives of ethyl hydrazinoacetate and either 2-acetylpyridine or 2-quinolinecarboxaldehyde, and of Pd(II) with the condensation derivative of ethyl hydrazinoacetate and ...
A study of the dispersity of iron oxide and iron oxide-noble metal (Me=Pd, Pt) supported systems
(Maik Nauka/Interperiodica/Springer, New York, 2007)
Samples of one-(Fe) and two-component (Fe-Pd and Fe-Pt) catalysts were prepared by incipient wetness impregnation of four different supports: TiO2 (anatase), gamma-Al2O3, activated carbon, and diatomite. The chosen synthesis ...
Synthesis of (-)-cytoxazone and (+)-epi-cytoxazone: The chiral pool approach
(Taylor & Francis, 2005)
Immunomodulator (-)-cytoxazone and its epimer (+)-epi-cytoxazone were synthesized starting from (D)-(-)-4-hydroxyphenylglycine. Homologation of the amino acid was achieved via the corresponding aldehyde, by a cyanohydrin ...
Characterization and catalytic activity of poly(4-vinylpyridine-co-divinylbenzene)-Co2+ complex
(Trans Tech Publications Ltd, Durnten-Zurich, 2005)
Poly(4-vinylpyridine-co-divinylbenzene)-Co2+ was characterized using infrared spectroscopy (IR), thermogravinietric analysis (TG-DTA), N-2-physisorption and polarography. Thermal analysis suggests sufficient thermal stability ...
Flowability of electrolytic copper powder
(Trans Tech Publications Ltd, Durnten-Zurich, 2005)
The surface structure of powder particles, which allows free flow of copper powder, was examined. It has been shown that a sufficiently dense surface structure which permits free flow will be obtained if apparent density ...
The influence of acid treatment on the nanostructure and textural properties of bentonite clays
(Trans Tech Publications Ltd, Durnten-Zurich, 2005)
The nanostructure and textural properties of acid-activated bentonite clays from the Bogovina coalmine were investigated. The acid activation was performed with HCl in the concentration range 1.5-7.5 M. The atomic force ...
Study of supported Pt and PtRu catalysts in methanol and formic acid oxidation
(Trans Tech Publications Ltd, Switzerland, 2004)
The kinetics of methanol and formic acid oxidation on supported Pt and Pt2Ru3 catalysts are measured in 0.5 M H2SO4 at ambient temperature using thin-film rotating disc electrode (RDE) method. Both catalysts are characterized ...
