Chemical investigation of hassium (element 108)
The periodic table provides a classification of the chemical properties of the elements. But for the heaviest elements, the transactinides, this role of the periodic table reaches its limits becauseExpand

Evidence for the formation of sodium hassate(VIII)
Summary Hassium, element 108, was produced in the fusion reaction between 26Mg and 248Cm. The hassium recoils were oxidized in-situ to a highly volatile oxide, presumably HsO4, and were transportedExpand

Fluoride complexation of rutherfordium (Rf, element 104)
The fluoride complexation of the group-4 elements Zr, Hf and Rf, and of the pseudo-homolog Th, has been investigated in mixed HNO3/HF solutions by studying Kd values on both cation exchange resinsExpand

Extraction behavior of rutherfordium into tributylphosphate from hydrochloric acid
The extraction behavior of rutherfordium (Rf) into tributylphosphate (TBP) from hydrochloric acid (HCl) has been studied together with those of the lighter group-4 elements Zr and Hf. TheExpand

Chemical Properties of Element 105 in Aqueous Solution: Extraction of the Fluoride-, Chloride-, and Bromide Complexes of the Group-5 Elements into an Aliphatic Amine
Previously, the halide complex formation of the group-5 elements had been studied in mixed HCL/HF solutions by their extraction into triisooctyl amine (TiOA). The extraction sequence Ta > Nb > 105 >Expand

48Ca+249Bk fusion reaction leading to element Z = 117: long-lived α-decaying 270Db and discovery of 266Lr.
The superheavy element with atomic number Z=117 was produced as an evaporation residue in the (48)Ca+(249)Bk fusion reaction at the gas-filled recoil separator TASCA at GSI Darmstadt, Germany. TheExpand

Rapid Communication: Aqueous Chemistry of Seaborgium (Z = 106)
Seaborgium was previously eluted from cation exchange columns like its homologs molybdenum and tungsten in 0.1 Μ HNO3/5 Χ 10" Μ HF. Its chemical form was presumably a neutral or anionic oxygenExpand
