Evolution of the Milky Way halo by accretion of dwarf satellite galaxies

, 2011
Within the Cold Dark Matter scenario the hierarchical merging paradigm is the natural result to form massive galactic halos by the minor mergers of sub-halos and, by this, inherently their stellar halo.

Chemical abundance analysis of 19 barium stars

, 2016
We aim at deriving accurate atmospheric parameters and chemical abundances of 19 barium (Ba) stars, including both strong and mild Ba stars, based on the high signal-to-noise ratio and high resolution Echelle spectra obtained from the 2.16 m telescope at

Protocol for producing phosphoramidate using phosphorus fluoride exchange click chemistry

STAR Protocols
Summary: Phosphorus fluoride exchange (PFEx) is a catalytic click reaction that involves exchanging high oxidation state P–F bonds with alcohol and amine nucleophiles, reliably yielding P–O- and P–N-linked compounds. Here, we describe steps for preparing
