Postdoc in Additive Manufacturing of 3D Carbon Electrodes for Energy Storage

Applicants are invited to apply for a postdoctoral scholar position in sustainable development at Technical University of Denmark, Denmark. Candidates are welcome before July 07, 2020.

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 (postdoc scholarships) 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 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 (nanotechnology scholarships) 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. Your main contribution will be the fabrication of 3DCMEs with mm-size and m 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: PhD diploma or a statement from the PhD supervisor documenting a satisfactory progress of the PhD study Candidates may apply prior to obtaining their PhD degree, but cannot begin before having submitted their PhD thesis.

Applications and enclosures received after the deadline will not be considered. All interested candidates irrespective of age, gender, race, disability, religion or ethnic background are encouraged to apply. DTU Nanolab is the National Centre of Nanofabrication and Characterization owned by and located at DTU with approximate 100 staff members. DTU Nanolab operates and maintains advanced processing equipment within 1350 m 2 , class 10-100, ISO 9001-certified, open access, pay-per-use cleanroom facilities. In a separate specially constructed building the center operates 8 state-of-the-art electron microscopes, among them four Transmission Electron Microscopes (TEM) and a Dual Beam Scanning Electron Microscope (FIB SEM). Technology for people DTU develops technology for people. With our international elite research and study programmes, we are helping to create a better world and to solve the global challenges formulated in the UN's 17 Sustainable Development (latest Sustainable Development scholarship positions) Goals. Hans Christian rsted founded DTU in 1829 with a clear vision to develop and create value using science and engineering to benefit society. That vision lives on today. DTU has 11,500 students and 6,000 employees. We work in an international atmosphere and have an inclusive, evolving, and informal working environment. Our main campus is in Kgs. Lyngby north of Copenhagen and we have campuses in Roskilde and Ballerup and in Sisimiut in Greenland.
