General information
Organisation
The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in four main areas :
• defence and security,
• nuclear energy (fission and fusion),
• technological research for industry,
• fundamental research in the physical sciences and life sciences.
Drawing on its widely acknowledged expertise, and thanks to its 16000 technicians, engineers, researchers and staff, the CEA actively participates in collaborative projects with a large number of academic and industrial partners.
The CEA is established in ten centers spread throughout France

Job description
Despite established cultures of coccolithophore microalgae and attainable large-scale production of coccolith biominerals (gram quantities of calcite mineral from litres of culture), the coccolith as an advanced functional material has made little progress in bionanotechnologies. This project will quantitatively describe metal doping into and on the surface of coccolith-based calcite for several transition metals, main group elements and lanthanides. Elucidating the potential of coccolithophore to incorporate metal ions into/onto biogenic calcite production will not only reveal the biotechnological possibilities for coccolith materials but will offer insights on the role of metals in the biomineralization process and the biological screening effect. Metal-doped coccolith materials will be subjected to physical and chemical characterization (focus placed on strategic metals that have enchanced incorporation into biogenic calcite or can be replaced/deposited on coccoltih surface). Select metal-doped coccolith candidates will be pursued for biotechnological application accordingly based on their physical and optical properties (e.g., catalytic activity for transition metals and photoluminescence for lanthanides).
