PhD student (m/f/x): Combinatorial synthesis and high-throughput characterization of thin film high entropy materials for the CO2 reduction reaction (CO2RR)
Are you interested in working in the rapidly evolving research field of high entropy materials for electrocatalysis? As part of the international ERC Synergy project DEMI (Directed Evolution of Metastable Electrocatalyst Interfaces for Energy Conversion), a position for a PhD student (m/f/x) is available as soon as possible. Besides RUB, University of Copenhagen (Denmark), Helmholtz Institute Erlangen Nuremberg and University of Bern (Switzerland) are involved in DEMI. This team works together intensively to make progress in electrocatalysis for the energy systems of the future. At DEMI, new high-entropy alloys are calculated in Copenhagen. The Bochum team produces thin-film materials libraries and uses high-throughput methods for characterization. The partners in Erlangen and Bern carry out experimental electrochemistry.
High entropy materials are systematically produced in large compositional spaces by combinatorial sputtering and the chemical composition, crystal and microstructure as well as the electrochemical properties are investigated by high-throughput methods. This screening is accelerated by artificial intelligence methods, e.g. "active learning", in order to discover new, active and stable materials for the CO2 reduction reaction (CO2RR). The future PhD student (m/f/x) is expected to work independently with high motivation, be able to collaborate in international teams in a goal-oriented manner, efficiently translate results into scientific publications, has very good scientific, technical and communication skills, be fluent in written and spoken English.
Scope: full-time
Duration: fixed-term, 3 Jahre

RUB sees itself as a university with an international presence. The campus languages are German and English. Competence in at least one of the two languages and the willingness to learn the other are a prerequisite. RUB provides corresponding free courses for employees.
German language courses are offered by the University Language Center (ZFA) in the field of German as a Foreign Language (DaF). https://www.daf.ruhr-uni-bochum.de/sbgk/index.html.en
The Staff Council has the right to participate in all selection interviews. At the request of a candidate (m/f/x), it will ensure its participation in the entire procedure. Please contact wpr@rub.de.
The Ruhr-Universität Bochum is one of Germany’s leading research universities, addressing the whole range of academic disciplines. A highly dynamic setting enables researchers and students to work across the traditional boundaries of academic subjects and faculties. To create knowledge networks within and beyond the university is Ruhr-Universität Bochum’s declared aim.
The Ruhr-Universität Bochum stands for diversity and equal opportunities. For this reason, we favour a working environment composed of heterogeneous teams, and seek to promote the careers of individuals who are underrepresented in our respective professional areas. The Ruhr-Universität Bochum expressly requests job applications from women. In areas in which they are underrepresented they will be given preference in the case of equivalent qualifications with male candidates. Applications from individuals with disabilities are most welcome.
