The Paul Scherrer Institute PSI is the largest research institute for natural and engineering sciences within Switzerland. We perform cutting-edge research in the fields of future technologies, energy and climate, health innovation and fundamentals of nature. By performing fundamental and applied research, we work on sustainable solutions for major challenges facing society, science and economy. PSI is committed to the training of future generations. Therefore, about one quarter of our staff are post-docs, post-graduates or apprentices. Altogether, PSI employs 2200 people.

For the Laboratory for Waste Management LES of the Nuclear Energy and Safety Research Division NES we are looking for a
PhD Student
In the field of Cement Environmental Chemistry
Your tasks
The project aims to decipher the formation pathways and chemical structures of FeII/III-hydrotalcites in Mg-cement and to determine their thermodynamic properties and redox behaviors. As a PhD Student you will be registered in the Institute of Geology in University of Bern.

During your PhD study your research activity will be on:
  • Deciphering the chemical structures of synthesized FeII/III-hydrotalcites
  • Investigating the redox process between the FeIII- and FeII-hydrotalcites and exploring the possible redox reversibility between the FeII and FeIII sites
  • Elucidating the retention mechanisms of critical redox-sensitive toxic anions (AsO43– and CrO42−) by FeII/III-hydrotalcites
  • Contribute to side projects, support to master thesis student, laboratories maintenance, improve security protocols in laboratory
  • Publication of results in journals or conferences
Your profile
  • Excellent qualifications with a university degree (Master or equivalent) in Chemistry, Materials Science or Physical Chemistry
  • Solid knowledge in materials science and heavy metal immobilization
  • Rich experience with wet chemistry methods, solid characterizations, and molecular simulations
  • Excellent communication skills in English (written and spoken)
We offer
Our institution is based on an interdisciplinary, innovative and dynamic collaboration. You will profit from a systematic training on the job, in addition to personal development possibilities and our pronounced vocational training culture. If you wish to optimally combine work and family life or other personal interests, we are able to support you with our modern employment conditions and the on-site infrastructure.

For further information, please contact Dr Bin Ma, phone +41 56 310 43 13.

Please submit your application online by 31 January 2023 (including addresses of referees) for the position as a PhD Student (index no. 4404-01).
