We are looking for a postdoctoral researcher to join the project project ‘Pyrolytic Hierarchical Organic Electrodes for sustaiNable Electrochemical Energy Systems (PHOENEEX)’ funded by a European Research Council (ERC) Consolidator Grant. In this context, the postdoc will work in close collaboration with several researchers in an interdisciplinary team. 

The overall vision of PHOENEEX is to develop miniaturised systems for energy harvesting and energy storage. For this purpose, we will investigate novel approaches for the fabrication of 3D carbon microelectrodes (3DCMEs) with highly tailored material properties, large surface area and hierarchical architecture using pyrolysis. In this process, patterned polymer precursors are exposed to high temperatures (> 900 °C) in inert atmosphere (N
2 or Ar) and converted into pyrolytic carbon. We will apply the 3DCMEs to i) considerably improve the efficiency of energy harvesting in microbial fuel cells and ii) enhance temporal storage of the harvested energy in microsupercapacitors. 

We are based at DTU Nanolab, where we conduct interdisciplinary research and where micro- and nanotechnology is applied to a wide range of scientific disciplines and applications. The Biomaterial Microsystems group is a highly ambitious group, pursuing research on microfabrication of 3D polymer and carbon structures and devices and their application in drug delivery, bioelectrochemistry and biosensing.

Responsibilities and tasks
Your main contribution will be the fabrication of 3DCMEs with mm-size and µm features using a combination of stereolithography and pyrolysis in the research laboratories of DTU Nanolab. The material properties of the carbon material will be characterized using methods such as XPS, Raman spectroscopy, XRD, SEM and BET. The performance of the 3DCMEs for electrochemical energy storage will be investigated using methods such as cyclic voltammetry and charge-discharge measurements. Methods for chemical modification of the electrodes will be investigated with the aim to increase the surface area and enhance capacitive energy storage. Finally, integration of the electrodes in a full microcapacitor cell will be attempted. 

We expect that you:
 

  • embrace the responsibility to plan and execute experimental research
  • are interested in material science, polymer engineering and microfabrication and are eager to explore new research areas
  • have extensive experience with carbon materials and pyrolysis
  • have successfully designed and fabricated carbon microelectrodes and demonstrated methods for surface modification
  • have excellent engineering skills and an analytical mindset
  • are motivated to contribute to technology enabling energy storage
  • like teamwork and have the ability to interact and collaborate with researchers and laboratory technicians in a very cross-disciplinary environment
Qualifications
Candidates should have a PhD degree in engineering or a related field.  

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 period of employment is 2 years.

Workplace
The microfabrication will be carried out at DTU Lyngby Campus at DTU Nanolab, providing the infrastructure necessary to conduct the research in this ambitious project.
