comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولBipolar ejection by the symbiotic binary system Z And during its 2006 outburst ⋆
High resolution data in the region of the line Hα have been obtained at the time of the light maximum and after it of the 2006 optical outburst of the symbiotic binary Z And. A blue-shifted absorption component indicating outflow velocity of about 1400 kms as well as additional emission components with similar velocities, situated on the two sides of the main peak of the line were observed duri...

15 صفحه اولA NuSTAR observation of the fast symbiotic nova V745 Sco in outburst
The fast recurrent nova V745 Sco was observed in the 3–79 keV X-rays band with NuSTAR 10 d after the optical discovery. The measured X-ray emission is consistent with a collisionally ionized optically thin plasma at temperature of about 2.7 keV. A prominent iron line observed at 6.7 keV does not require enhanced iron in the ejecta. We attribute the X-ray flux to shocked circumstellar material. ...
متن کاملMASS EJECTION FROM THE SYMBIOTIC PROTOTYPE Z And DURING ITS 2006 OUTBURST
High-resolution spectroscopic observations in the region of the Balmer Hα and Hγ lines of the symbiotic binary Z And were performed during its major eruption in 2006. The Hα line had additional satellite high-velocity components situated on either side of its central peak which indicated bipolar collimated outflow from the compact object. The Hγ line presented three components, consisting of a ...
