The Postdoc position is offered in the section Neutrons and X-rays for Materials Physics (NEXMAP) at DTU Physics focuses on gaining knowledge on fundamental properties of materials through experiments conducted at neutron and X-ray facilities around the world. Development of instruments, software for virtual experiments, and novel data analysis methods play a key role in this effort.

Nanoparticles are constantly released into our environment both from natural and manmade sources. We are interested in understanding the mechanisms of their transport and deposition when they are transported in porous media. The present 2-year Postdoc position is funded by the VILLUM Experiment programme and the goal is to enable direct visualisation of nanoparticle transport inside bulk porous media in situ at the nanometre scale. To achieve this goal, we will develop an experimental setup that permits injection of nanoparticle suspension into very tiny samples (diameter ~50 micrometre) while performing X-ray nanotomography to determine the 3D microstructure of the sample.  The current project is also part of the new Danish centre of excellence, SOLID, that is focused on visualisation of the internal structure in solid materials (www.solid.dtu.dk).

Responsibilities and tasks
We are looking for a highly motivated candidate, which is not afraid of a challenge and with a strong interest in experimental materials science. The candidate will

  • Investigate possible technical solutions (designs) for the in situ cell for nanotomography
  • Be responsible for developing and constructing the in situ cell
  • Testing performance of the in situ cell
  • Make the first studies of nanoparticle transport in chalk
  • Analyse and quantify image data
  • Write beamtime proposals, experimental reports and scientific articles
  • Take part in supervising students

Qualifications
The successful candidates should have a PhD degree or equivalent in materials science, physics or chemistry. The candidate should have/be

  • Demonstrated extensive qualifications in experimental X-ray tomography and development of experimental equipment.
  • Experience with experimental work at the large facilities such as synchrotron facilities.
  • Documented expertise in synthesis and handling of nanoparticles.
  • Fluent in English both spoken and written.

The candidate should be self-motivated but also enjoy taking part in team work.

We offer
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility.

Salary and terms of employment
The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. The allowance will be agreed upon with the relevant union. The position is available from 1 January 2021 and has a duration of 2 years.
