On-line separation of short-lived tungsten isotopes from tantalum, hafnium and lutetium by adsorption on ion exchangers from aqueous ammonia solution
The title goal was achieved using a DOWEX 50Wx8 cation exchange column saturated with La(OH)3 and ammonia solution as eluent. Hf, Ta and Lu were adsorbed on this column, whereas W remained in the solution. This c...

First chemical investigation of hassium (Hs, Z=108)
Recently, the first successful chemical investigation of element 108, hassium (Hs) has been reported [1]. Based on 7 detected atoms, Hs was shown to form a higly volatile oxide, most probably HsO4. Therefore it b...
