For the Institute of Materials and X-Ray Physics of the Hamburg University of Technology at our location at the Deutsche Elektronen-Synchrotron (DESY) for the earliest possible date, we are lookingfor a:

RESEARCH ASSOCIATE (m/f/d) / WISSENSCHAFTLICHER MITARBEITER (m/w/d)



for a maximum of   36 months . The remuneration is in accordance with 13 TV-L


No.: 29922WM2


As a part of a collaborative project between the Deutsche Elektronen-Synchrotron (DESY), the Hamburg University of Technology and the University of Hamburg you will strongly contribute to the development of a sample environment for the direct investigation of modifications (e.g. segregations, phase transformations) of spatially confined matter under external stimuli (temperature, electrical potential, irradiation with light) using X-ray scattering methods and apply it for the experimental program of this project. Within the scope of the latter you will investigate the electrochemically stimulated rearrangement of ions in liquid electrolytes, as well as light-activated phase transformations of liquid crystals, in mesoporous membranes, while our partners from the University of Hamburg will investigate the temperature and electric field triggered formation of metal nanoparticles originating from the segregation of dopants in oxide ceramics. The elucidation of such processes is highly relevant for various technological processes (e.g. development of catalysts, actuators, understanding of energy storage processes, design of advanced (photonic) materials). Of particular interest are the expected correlations between the applied stimuli and the structural modifications of the confined matter. The high brilliance of PETRA III's synchrotron radiation will make it possible to study these processes in "real time" with outstanding accuracy. For this purpose, an innovative infrastructure for the simultaneous performance of anomalous small-angle X-ray scattering (ASAXS), anomalous wide-angle X-ray scattering (AWAXS) and X-ray absorption spectroscopy (XAS) in combination with electrochemical impedance spectroscopy and gas analysis will be combined in a single experiment at the beamline P62 at PETRA III. The combination of several methods is realised by developing a dedicated sample chamber and three sample cell inserts in which temperature, gas atmosphere, electrochemical potential and light irradiation can be changed with high accuracy and reproducibility. Automated control of the measurements ensures synchronisation of data acquisition between the sample environment and the beamline.


YOUR TASKS

  • Development of a sample environment for in-situ X-ray scattering experiments at the P62 beamline at PETRA III (DESY) in close collaboration with the beamline staff and the two involved working groups from the Hamburg University of Technology and the University of Hamburg
  • Experiments on the electrochemically rearrangement of ions in liquid electrolytes and light-activated phase transformations of liquid crystals in our laboratories, as well as at the P62 beamline
  • Publication of the results in scientific journals and at international conferences.

YOUR PROFILE

  • You have a PhD in Physics, Materials Science, Physical Chemistry or Mechanical Engineering with a strong background in the aforementioned fields.
  • Preferably you already have experience in one of the following fields: porous materials, thermodynamics, hydrodynamics, electrochemistry, X-ray physics, condensed-matter physics
  • Additionally of advantage are kills in CAD, dimensioning of components, programming (e.g. Python) and electronics
  • Profound knowledge of English and ideally, but not mandatory, good knowledge of German.

    OUR OFFER

    • An interdisciplinary, international and collaborative environment. The Institute for Materials and X-Ray Physics is located on the Science City Bahrenfeld Campus as a bridge institution between Hamburg University of Technology and the Photon Science division of the Deutsche Elektronen-Synchrotron DESY, additional details can be found on our website.
