Department of Chemistry of the f-elements

Research

Background:

The understanding of the physical/chemical behaviour of an element in engineered or environmental systems requires fundamental knowledge of the chemistry of the relevant element. The Institute of Resource Ecology at HZDR is recognised to possess a long history in the research of nuclear-related elements, such as actinides or lanthanides, in various applied systems, particularly for geological disposal of radioactive wastes. In order to provide solid scientific foundation for these existing research activities in the applied systems as well as to explore new research fields associated with nuclear-related elements, the Department of Chemistry of the f-elements, established in June 2014, is focusing on the fundamental coordination and solution chemistry of f-elements, i.e., actinides and lanthanides, with a wide range of inorganic- and organic ligands relevant to the geological disposal of radioactive wastes.

Research subjects:

• Coordination chemistry of f-elements with inorganic- and organic ligands (e.g. naturally relevant and bio-related ligands)
• Solution chemistry, colloid chemistry and electrochemistry of f-elements
• Polymer and cluster chemistry of f-elements
• Development of theoretical calculation codes for 5f systems (i.e. actinides)
• Theoretical interpretation of spectroscopic data on f-elements (i.e. NMR and XAS (XANES))
