Postdoctoral Scholarship in Energy Engineering with Special Emphasis on Oxidation of Carbon Nanostructures: Surface Dynamics

Luleå University of Technology is in strong growth with world-leading competence in several research areas. We shape the future through innovative education and ground-breaking research results, and based on the Arctic region, we create global social benefit. Our scientific and artistic research and education are conducted in close collaboration with international, national and regional companies, public actors and leading universities. Luleå University of Technology has a total turnover of SEK 1.9 billion per year. We currently have 1,840 employees and 17,670 students.

In the coming years, multi-billion investments will be made in large projects in Northern Sweden to create a fossil-free society both nationally and globally. Luleå University of Technology is involved in several of these cutting-edge research projects and in the societal transformation that they entail. We offer a broad range of courses and study programmes to match the skills in demand. We hope that you will help us to build the sustainable companies and societies of the future.

The Subject of Energy Engineering at Luleå University of Technology (LTU) invites highly motivated candidates interested in conducting research on: Surface Dynamics during Oxidation of Carbon Nanostructures

Description of the research subject
The subject of Energy Engineering at the Division of Energy Science belongs to the Department of Engineering Sciences and Mathematics. At the subject of Energy Engineering, we work closely with companies/industries in both research and student projects. The research conducted has high international standards, and we collaborate with researchers around the world.

Energy engineering includes the development of technologies and processes for sustainable energy supplies.  The research focuses on bioenergy technologies and energy efficient use in industry and society. We coordinate or participate in many research programs and projects funded by, e.g., Swedish Energy Agency and Swedish Research Council.

Framework and duration of the scholarship
Controlling the formed amount and nanostructure of carbon nanomaterial, such as graphene nanoplates, carbon nanotubes, carbon black, and soot, via oxidative processes is essential in many different fields ranging from emissions control (soot) to production of bulk chemical (carbon black), and advanced nanomaterials (graphene, carbon nanotubes). However, owing to the large heterogeneity of carbon nanomaterials in terms of constituent carbon allotropes and heteroatoms, the evolution of oxidation mechanisms at the nano-to-atomic scale have to date not been explored in detail. In situ electron microscopy performed either in the scanning electron microcopy (SEM) or in the transmission electron microscopy (TEM) are used by us to understand the dynamic oxidation process.

The oxidation of metal doped carbon nanoparticles will be investigated with in-situ SEM. The SEM give topographical and morphological information of the soot particles during the oxidation process. One important task is to develop a mathematical algorithm that based on image analysis can deal with overlapping primary particles and calculate the size of the soot particles in the agglomerate. From such information it will be possible to calculate the mass loss of the soot agglomerates as a function of time and determine how much the reaction rate is increased due to metal doping. The reaction rates obtained with in-situ SEM will be compared to the reaction rate determined with the TGA.

Qualifications
To qualify for the scholarship, you must have a Ph.D., a doctoral degree, or a foreign degree equivalent to a Ph.D. in Engineering Physics, Nanotechnology, Chemical Engineering, Energy Engineering, Material Sciences, or related subjects. Applicants finishing a Ph.D. within a few months are also encouraged to apply. Please note that the doctoral degree cannot be older then 5 years.

It is desirable that the applicant has documented experience and abilities in the following areas (listed by the order of importance). Please make sure to explicitly refer to these points in the letter of motivation.

Qualifications:

• Documented knowledge in electron microscopy (i.e., SEM or TEM)

• Documented experience in producing scientific publications,
• Good knowledge in the English language and good oral and written proficiency,
• A good team player with the ability to take initiatives.

Given equal qualification, priority will be given to the under-represented gender.
