Applications are invited for a PhD student on the topic: “Binding of multivalent radionuclides to dissolved organic matter – a multi-angle approach” in the Expert Group Waste& Disposal at the Belgian Nuclear Research Centre located in Mol, Belgium.
Preparing your doctoral thesis at the Belgian Nuclear Research Centre offers you the best of both worlds: you stay in close contact with the academic world and you enjoy a unique international research environment, with advanced nuclear experimental facilities and top-level guidance from our experts.
PhD students should register at a pre-defined university, depending on the topic of their PhD. They are doctoral students at the university, however, they are based in Mol (Belgium) for the greater part of the time.
Job Offer/PhD Topic Details
The objectives of this PhD are:
1. To provide insight into interaction mechanisms of multivalent (trivalent/tetravalent) metals and radionuclides with dissolved organic matter on a molecular scale by means of state-of-the-art analytical techniques, with the focus on slow kinetics observed in batch and transport studies and deemed responsible for colloid-facilitated transport.
2. To show differences and/or parallelism in the interaction of respectively tri- and tetravalent cations with DOM (i.e., to provide evidence of either complexation or colloid-colloid interaction)
This PhD will be performed in close cooperation with university labs (KU Leuven) and other research institutes (KIT-INE) that specialise in multiscale physicochemical characterisation of the interactions between multivalent metal ions or their clusters and organic ligands or their micellar associations, via complexation, surface adsorption, colloid/colloid or colloid/micelle interaction. Identification of such interaction mechanisms requires a combination of local structure elucidation with meso- and/or macroscale characterisation of the clusters and their behaviour, with techniques such as time-resolved laser fluorescence spectroscopy (TRLFS), diffusion ordered spectroscopy (DOSY) NMR, X-ray and neutron techniques (SAXS, SANS, XANES, EXAFS, STXM), etc.).
Preference is given to students younger than 25 years old, holding a Master degree (or equivalent) in Environmental Science or Chemistry, with at least a distinction in their final Master year.
PhD students will enrol at a university (in this case KU Leuven), and will also be employed by that university. SCK•CEN will draw up an agreement with the university in which, amongst others, the financial issues are described: SCK•CEN will cover for the personnel cost, according to the levels of the university, a lump sum to cover working costs, and the requested overhead.
Please submit your CV, accompanied by at least two reference letters from scientific collaborators of a university or scientific institute, of which one must come from your final-year university supervisor (professor who promoted your Master thesis), and one reference letter filled out by the promoter of the PhD thesis for which you are applying (contact the mentor for names and contact details).
Deadline for application is strict (06 April 2014).
Your file will be evaluated by the Scientific Council of SCK•CEN. When appraised positive, you will be invited to present your work. The final decision about your application will be taken after the oral presentation, and will be officially announced soon after.
