Stark Broadening of Co II Lines in Stellar Atmospheres

open access: yesData, 2020
Data for Stark full widths at half maximum for 46 Co II multiplets were calculated using a modified semiempirical method. In order to show the applicability and usefulness of this set of data for research into white dwarf and A type star atmospheres, the

Ni(II) and Co(II) Sensing by Escherichia coli RcnR [PDF]

open access: yesJournal of the American Chemical Society, 2008
Escherichia coli RcnR and Mycobacterium tuberculosis CsoR are the founding members of a recently identified, large family of bacterial metal-responsive DNA-binding proteins. RcnR controls the expression of the metal efflux protein RcnA only in response to Ni(II) and Co(II) ions.

Furannic Thiosemicarbazone Complexes of Co(II), Ni(II), and Cu(II) in Ethanol Solutions and of Co(II) in the Solid State [PDF]

open access: yesPhosphorus, Sulfur, and Silicon and the Related Elements, 2007
Thiosemicarbazone complexes with cobalt(II), nickel(II), and copper(II) metal ions are studied in ethanol solutions. The stability constants of all the identified complexes are calculated, and we found that stability increases from cobalt to copper. The stability of the complex is increased by the presence of a donor group like methyl, whereas it is ...
