Chemistry of superheavy elements.
- M. Schaedel
- Chemistry, Medicine
- Angewandte Chemie
- 9 January 2006
The number of chemical elements has increased considerably in the last few decades. Most excitingly, these heaviest, man-made elements at the far-end of the Periodic Table are located in the area of… Expand
Chemical investigation of hassium (element 108)
- Ch. E. Düllmann, W. Brüchle, +31 authors P. Zieliński
- Chemistry, Medicine
- Nature
- 22 August 2002
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 because… Expand
Evidence for the formation of sodium hassate(VIII)
- A. von Zweidorf, W. Brüchle, +9 authors N. Wiehl
- Chemistry
- 2004
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 transported… Expand
Fluoride complexation of rutherfordium (Rf, element 104)
- E. Strub, J. V. Kratz, +7 authors B. Schausten
- Chemistry
- 2000
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 resins… Expand
ARCA II – A New Apparatus for Fast, Repetitive HPLC Separations
- M. Schaedel, W. Brüchle, +4 authors H. P. Zimmermann
- Chemistry
- 1989
The microcomputer controlled Automated Rapid Chemistry Apparatus, ARCA, is described in its newly designed version for the study of chemical properties of element 105 in aqueous solutions. This… Expand
The hydration enthalpies of Md3+ and Lr3+
- W. Brüchle, M. Schaedel, +8 authors D. Hoffman
- Chemistry
- 15 June 1988
Lawrencium (3-min 260Lr) and lighter actinides were produced in the bombardment of a 249Bk target with 18O ions and loaded onto a cation exchange column in 0.05 M α-hydroxyisobutyrate solution at… Expand
Extraction behavior of rutherfordium into tributylphosphate from hydrochloric acid
- H. Haba, K. Tsukada, +29 authors J. V. Kratz
- Chemistry
- 2007
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. The… Expand
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
- W. Paulus, J. V. Kratz, +14 authors E. Sylwester
- Chemistry
- 1999
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.
- J. Khuyagbaatar, A. Yakushev, +69 authors V. Yakusheva
- Chemistry, Medicine
- Physical review letters
- 1 May 2014
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. The… Expand
Rapid Communication: Aqueous Chemistry of Seaborgium (Z = 106)
- M. Schaedel, W. Brüchle, +19 authors K. Gregorich
- Chemistry
- 1 December 1998
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 oxygen… Expand
