Thermophoresis or thermodiffusion describes the coupling between a temperature gradient and the resulting mass flow in a multicomponent system. The effect is discussed in connection with the question of the "origin of life" and is used as a powerful sensor to determine the binding constants of protein-ligand systems. Thermophoretic study of ions reveals ion-specific hydration, which is crucial for biological information processes. The goal of this project is to gain a better microscopic understanding through systematic studies of the thermodiffusion of salt solutions and chelating agents used to control ions. The results obtained will be used to improve and develop new theoretical concepts for the underlying physical mechanism. Your tasks will include:
- Characterization of samples using thermal diffusion forced Rayleigh scattering and isothermal titration calorimetry.
- Design and set-up of a conductometric cell for dilute salt solutions.
- Data evaluation and, if necessary, modeling of experimental results using finite element methods
- Participation in conferences in Germany and abroad (incl. presenting your research results)
- Exchange with internal and external as well as national and international project partners
- Preparing scientific publications
- A scientific university degree (Master) in the field of physical chemistry or (chemical) physics, with an overall grade of at least “gut” (or equivalent, e.g. cum laude)
- Expertise in thermodynamics, statistical mechanics and optics is desired
- Expertise in data and error analysis, and computer skills is desired.
- Experience in construction software e.g. Autocad and finite element method are a plus
- Experimental skills and perseverance
- Very reliable and conscientious style of working
- Commitment, high degree of team spirit, as well as enjoyment of cooperative teamwork
- Fluent command of written and spoken English, German language skills would be an advantage
