Postdoctoral Fellow in High pressure solid state chemistry

The Department of Chemistry, with more than 200 employees, is one of the largest at Stockholm University. Research spans all areas of chemistry such as analytical, physical, materials, inorganic and structural as well as organic chemistry. There are many research projects, from theory to experiment, from basic to more applied research, often focusing on sustainable chemistry but also advanced analytical methods of chemicals and materials. The Department has a very well-developed research infrastructure with state-of-the-art equipment and qualified support from staff scientists. The Department also hosts a Bachelor's degree program in Chemistry and Master's programs in Analytical Chemistry, Sustainable Chemistry, and Organic Chemistry. PhD programs are conducted in five areas: Analytical, Physical, Materials, Inorganic and Organic Chemistry. For more information about us, please visit: the Department of Chemistry.

Project description

The project aims at facilitating reactions of solids with fluid oxygen (“oxygenations”) at pressures up to 20 GPa (200 kbar, ~200,000 atm) and temperatures in excess of 1000 °C using large-volume press (LVP) high pressure methodology. This capability will greatly enhance the synthesis potential for new solid state oxides in which later 3d transition metals (Fe – Cu) are locked in expanded oxidation states and provide a unique opportunity to experimentally test theoretical predictions of existence of elusive materials with potentially interesting magnetic states and/or electrical transport properties. Most parts of the research will be performed at the synchrotron radiation facility PETRA III in Hamburg, Germany, and utilizing in situ diffraction for monitoring oxygenation reactions at extreme pressure and temperature conditions.

Main responsibilities

We are seeking a postdoctoral researcher who will help further developing existing methods and protocols for LVP oxygenations and engage in performing experiments at PETRA III. It is estimated that the researcher visits PETRA III about four times per year and spends in total three months per year at the synchrotron facility. The researcher will be responsible for the analysis of obtained in situ diffraction data and writing reports and publications - as lead author- that emerge from the performed experiments. Responsibilities further include the synthesis of precursor materials for LVP oxygenations by solid state chemistry techniques and involvement in the characterization of structural and physical properties of new materials. The postdoctoral researcher is expected to contribute actively to the intellectual environment of the research group, collaborate with other researchers within the department and at PETRA III, and present results at international conferences. Some supervision of students may be included.

Qualification requirements

In order to qualify for a Postdoctoral position, applicants are required to hold a Swedish doctoral degree or an equivalent relevant degree from another country. The degree must have been completed no later than when the employment decision is made.

Assessment criteria

It is considered an advantage if the doctoral degree or an equivalent degree was completed no more than three years prior to the application deadline. Under special circumstances, an older degree may also be an advantage. Special circumstances refer to sick leave, parental leave, elected positions in trade unions, service in the total defense, or other similar circumstances, as well as clinical attachment or service/assignments relevant to the subject area. The doctoral degree should be in solid state chemistry, physical chemistry, materials sciences, or geo/earth sciences.

In the evaluation process, special attention will be given to:

• Proven experience with LVP multi-anvil high pressure techniques
• Documented proficiency in using X-ray diffraction for phase identification, structure solution and structure  refinement of inorganic materials
• Proven experience in working at large scale facilities (synchrotron and/or neutron), accompanied with the handling of data produced at large scale facilities
• Experience in solid state chemistry synthesis techniques and basic familiarity with physical characterization methods, such as IR/Raman/UV-VIS spectroscopy, scanning electron microscopy, thermal analysis, and magnetometry.
• Written and oral proficiency in English
• Demonstrated academic publishing record (commensurate with career stage)
• The ability to collaborate and networking
• Creativity, initiative, and independence.

About the employment

The position involves full-time employment for a minimum of two years and a maximum of three years, with the possibility of extension under special circumstances. Start date 2026-06-01 or as per agreement.
