The project involves research in the area of thin-film growth using Chemical Vapor Deposition (CVD), development of processes and equipment for CVD, fundamental materials science studies of thin films syntheiszed with CVD, as well as application-oriented studies in collaboration with industrial partners. The postdoctoral researcher will play an important role in the development of CVD activities within the research program for inorganic chemistry.

The main duties involved in a post-doctoral posistion is to conduct research. Teaching may also be included, but up to no more than 20% of working hours. The main duties involved in a post-doctoral position is to conduct research. Teaching may also be included, but up to no more than 20% of working hours. The focus is on developing and characterizing processes for CVD of primarily carbonitrides and oxides, characterizing the materials, with ample space for the postdoctoral researcher’s own project ideas within the overall framework of the CVD research activities. The tasks also include supervising thesis students, internal collaborations, including with doctoral candidates, and cooperation with industrial partners.

Most rivers are heavily influenced by humans. In many places, rivers are therefore being restored to promote water quality and biological diversity. Construction of wetlands and dam removal are two common measures, and both lead to an increased abundance of macrophytes, i.e. plants in or near water. Macrophytes can emit significant amounts of greenhouse gases, but at the same time also bind carbon and thus constitute a carbon sink. The CLIMIPHY project aims to create new knowledge about the climate footprint of macrophytes that gives river restoration professionals the opportunity to restore watercourses in a way that favors biodiversity and water quality, with as little climate footprint as possible.

The postdoctoral researcher will work in an exciting sub-project that uses new drone technology to perform field measurements the emission of greenhouse gases from river restoration areas. The work takes place in close collaboration with other project team members, and under joint supervision together with meteorologists at the Department of Earth Sciences: https://www.uu.se/en/department/earth-sciences/research/air-water-and-landscape-science/meteorology

Your main tasks will be to finalize the NESSA 14-MeV neutron facility and contribute to developing the experimental program at NESSA. Neutrons are a key player in nuclear applications. The availability of neutron sources is especially important for developing and testing detectors for nuclear physics experiments and applications, development and testing of nuclear instruments for verification of nuclear safeguards and disarmament, radiation-shielding studies, development and verification of simulation tools for neutron transports, and irradiation of material and electronics. After the closing of several research reactors and accelerator-based neutron sources (e.g. The Svedberg Laboratory in Uppsala), there is a current lack of neutron facilities in the Nordic countries.

The NESSA facility is located in the FREIA hall at Ångström laboratory in Uppsala. It is planned to be equipped with an intense, 10^10 n/s DT generator that needs to be procured. For testing existing installations in the bunker, a weaker DT generator will be installed in early 2025.

In this project, we test NESSA with the weaker generator, procure a commercially available strong DT generator, and commission the facility. You will work together with researchers from research groups at the division and other interested partners to develop and perform, e.g., test experiments related to fission and fusion research, detector development, electronic irradiations, material analysis, and educational activities for students and industrial partners.

We are looking for a postdoctoral fellow to be stationed at the SuperADAM instrument at ILL, Grenoble. SuperADAM is the only fully Swedish owned and operated neutron instrument. It is a high-resolution polarized neutron reflectometer suited for magnetic, hard condensed matter and soft matter, as well as life science investigations. The duties of the successful candidate include the support of users on the instrument, to conduct his/her own research, as well as to work with the continued development and upgrade of the instrument. Besides functioning as a beam line scientist, the postdoctoral fellow is expected to develop his/her research, within the areas soft matter, magnetism or similar, which will be performed both at ILL and the three partner universities (Uppsala, Lund and Linköping). The research direction is mostly determined by the expertise and interests of the candidates, but experience of neutron scattering of interest for Swedish users of SuperADAM is presupposed. This research should ideally build on and expand existing collaborations between the ILL and the three partner Universities, and thereby exploit capabilities in Grenoble, (e.g. the partnership for soft condensed matter ( http://www.epn-campus.eu/users/partnership-for-soft-condensed-matter-pscm/) and/or in Sweden, (e.g. thin film deposition and x-ray reflectivity characterization). An interest in the use of magnetic reference layers, as well as off-specular scattering, are examples of possible strength areas that utilize the capacity of the instrument.

We are looking for a postdoctoral fellow with a strong background in software development, or software developer with a strong interest in science. You will join a new project, within which applied statistics and information theory is used to quantify the information content of neutron reflectivity datasets. Using this, we are able to optimize the design of experiments and to make previously impossible experiments possible, as well as to run existing experiments faster and better.

In a facility where a typical experiment lasts few days, costs tens of thousands of pounds/Euros and takes 6+ months to apply for, any improvements to the experiment are of large value. The effort will be based on an existing code-base we have developed to design optimal thin film structures for a given purpose. These structures will be fabricated by other members of the collaboration and measured using a variety of methods including neutron reflectivity experiments. Participation and collaboration with all other parts of the project is strongly encouraged and if the candidate chooses, they can participate in the large-scale facility experiments.

The code-base is released as an open-source project, with an emphasis on sustainable software engineering (https://github.com/jfkcooper/HOGBEN) and has two journal articles published.  Significant development of the capabilities of the code-base is required. These will include improvements to the experimental design code, as well as improving the data analysis, applying Bayesian methods for extracting parameter uncertainties and model selection. The developments will allow the entire collaboration to move forward, suggesting optimal materials systems to be investigated and designing experiments for the other nodes of the project.

The position is based in Sweden but involves shorter as well as extended stays in the UK and France, working at ISIS and ILL. Visits to ESS are also assumed. There will be the opportunity for overseas travel to meet international collaborators, and to present the work at workshops/conferences.

Participate in the design and construction of superconducting magnets. Hands-on preparation of cold tests of magnets and cavities. Plan and monitor measurements, troubleshoot experiment setups, and operate the cryogenic and vacuum infrastructure. Report on and document the activities.

In addition to the magnet-related activities, the candidate will assist in the overall development and evaluation of instrumentation and experiments at the FREIA Laboratory. Active contribution to outreach activities and to the supervision of students is expected. The work will involve domestic and international travel.

You will be responsible for developing a damage coupled diffusion finite element model that captures the progressive destruction of cell walls during chemical delignification as well as the evolution of diffusion coefficients as a function of the damage. A finite element representation of real wood microstructure will be constructed based on XRT data, and delignification as well as damage evolution will be simulated. For model calibration and verification, laboratory permeation experiments will be designed and carried out.

In addition to research, some participation in supervision of doctoral students, master’s and project students as well as communication of research results through scientific articles in well-established scientific journals and presentations at international conferences are also included as important aspects of the employment. Some participation in undergraduate teaching may also be included. You are also expected to contribute to applications for external research funds.

Those qualified for appointment as a postdoctoral fellow have been awarded a Degree of Doctor or an equivalent qualification awarded by a foreign higher education institution. The degree should have been awarded no more than three years before the deadline for applications. If special grounds exist, consideration may be given to applicants who were awarded a Degree of Doctor earlier. Special grounds may be parental leave, sick leave, elected office in a trade union, leave of absence to serve in the Swedish defence forces or similar circumstances, or a clinical position or other service/assignments of relevance to the position.

The successful candidate shall not have been previously employed as a postdoctoral fellow at Uppsala University for more than one year within the same or an adjacent subject area.
