EPFL - Postdoctoral Research Opportunity
vor 3 Tg.

The research consortium on Solar Nitrogen Fixation, formed by the groups of V. Artero (CEA Grenoble, France), C. Bostedt and M.

Chergui (EPF Lausanne, Switzerland), V. Krewald (TU Darmstadt, Germany) and S. Schneider (University of Göttingen, Germany) is inviting applications for two PhD and two postdoctoral positions.

The aim of the consortium is to evaluate strategies for the development of molecular catalytic systems that use solar energy to convert nitrogen into ammonia, based on a mechanistic analysis of state-of-the-art N2 photoactivation complexes.

Several approaches will be examined to design platforms that facilitate photodriven N2 splitting and proton coupled electron transfer for N H bond formation, which define the thermochemical bottlenecks of nitrogen fixation.

The successful candidates will work in close collaborative exchange between the involved groups with expertise in synthetic inorganic chemistry, electrochemistry, ultrafast spectroscopy and computational chemistry.

Other positions are listed in the attached PDF. Each position has individual criteria and requirements. Please note that the administrative details, starting dates and application deadlines are specific to each position.

Your job

Postdoc position in ultrafast spectroscopy of inorganic complexes in the groups of

Prof. Dr. Majed Chergui and Prof. Dr. Christoph Bostedt.

The candidate will work on ultrafast optical and free-electron laser experiments on molecular catalytic complexes and reference molecules.

The optical experiments are performed in the LACUS laboratories at EPFL (Lausanne). The Lausanne lab offers a broad range of experimental strategies such as ultrafast transient absorption and 2-dimensional spectroscopy in the visible to the deep-UV, ultrafast fluorescence upconversion, ultrafast photoelectron spectroscopy of liquid solutions and ultrafast circular dichroism.

The ultrafast X-ray spectroscopic studies will be carried out at the Swiss Free Electron Laser (SwissFEL), at the Paul-Scherrer-Institut (PSI) in Villigen.

The new soft x-ray branch will offer few- to sub-femtosecond x-ray pulses as well as two-color capabilities from 250 to 1800 eV.

The new Maloja endstation, currently under construction, will offer opportunities for ultrafast x-ray spectroscopies in the soft x-ray regime in the gas, liquid, and solid phase.

Your profile

The candidate will participate in developing strategies for ultrafast spectroscopy at free-electron laser sources with a focus on nitrogen containing molecular complexes.

Solid knowledge of ultrafast laser spectroscopy and / or X-ray spectroscopy are expected, along with a motivation to high risk experiments.

We offer

The position is based in the Laboratory for Ultrafast X-ray Sciences at Ecole Polytechnique Fédérale de Lausanne (EPFL).

The optical laser experiments will be performed in the LACUS laboratories at EPFL but frequent travel to the free-electron laser facility at Paul Scherrer Institute in Villigen or other XFEL sources must be expected.

The position is limited to three years. Interested candidates should submit CV, motivation letter and the contact details of two referees to Prof.

Christoph Bostedt by e-mail quoting the reference SolarN2.
