Europium abundances in F and G disk dwarfs ⋆ ⋆ ⋆
Europium abundances for 74 F and G dwarf stars of the galactic disk have been determined from the 4129.7 Å Eu ii line. The stars were selected from the sample of Edvardsson et al. (1993) and [Eu/Fe] shows a smaller scatter and a slightly weaker trend with [Fe/H] than found by Woolf et al. (1995). The data of the two analyses are homogenized and merged. We also discuss the adopted effective temp...
متن کاملSilicon-[F]Fluorine Radiochemistry: Basics, Applications and Challenges
Silicon-[F]fluorine (Si-F) radiochemistry has recently emerged alongside other unconventional approaches such as aluminum-F and boron-F based labeling strategies, reshaping the landscape of modern F-radiochemistry. All these novel methodologies are driven by the demand for more convenient F-labeling procedures to further disseminate one of the most sophisticated imaging technologies, Positron E...
متن کاملSynthesis and Characterisation of the Europium (III) Dimolybdo-Enneatungsto-Silicate Dimer, [Eu(α-SiW9Mo2O39)2]13−
The chemistry of polyoxometalates (POMs) keeps drawing the attention of researchers, since they constitute a family of discrete molecular entities whose features may be easily modulated. Often considered soluble molecular oxide analogues, POMs possess enormous potential due to a myriad of choices concerning size, shape and chemical composition that may be tailored in order to fine-tune their ph...
