The Institute of Crystallography at RWTH Aachen University is placed in the interdisciplinary field of chemistry, physics, geo- and material sciences. Our research aims at a better understanding of the structure and dynamics of nanoscale solid-liquid and solid-gas interfaces, because of their importance in catalysis, for energy materials, geoscience and nanomaterials.
Understanding interfacial properties of nanoparticle-solvent interfaces is crucial to optimize applications of nanostructured materials in the field of (photo-) catalysis, nanotechnology, or also biomedicine. The structure and dynamics of solvent and organic ligand molecules at surfaces of metal oxide nanoparticles are not identical to the respective properties in bulk liquids. Our general understanding of these interfacial properties is still limited. How do solvent layers build up at nanoparticle surfaces in dispersion and in humid atmospheres? How does ligand coverage impact solvent layering? How do solvent layers in turn impact the diffusional mobility of ligands on the surface? How do solvent mixtures in the synchrotron beam affect redox chemistry in the nanoparticles?
As PhD student (f/m/d) you achieve fascinating insight into interfaces of metal oxide nanoparticles with their surroundingswith the following tasks:
• Synthesis of non-magnetic metal oxide nanoparticles (TiO2, ZnO, etc.)
• Characterization techniques of particle and interface properties, e.g. TGA, TEM, IR or DLS.
• X-ray and / or neutron scattering experiments at synchrotron and / or neutron radiation facilities (national andinternational).
• Data analysis and interpretation, e.g. with Igor Pro, Python, Origin.
• Publication of results in peer-reviewed scientific journals and presentation at conferences.
• University degree (Master or equivalent) in chemistry, materials science, geoscience, physics or related field.
• Experience in at least two of the following: (nanoparticle) synthesis, X-ray / neutron scattering, physicochemicalcharacterization (TGA, DLS, IR etc.), data analysis / scientific programming (Origin, Igor Pro, Python).
• High motivation for further training, independent and goal-oriented way of working.
• Good communication skills in English and possibly German.
• You are interested in further academic qualifications (doctorate).
All applications must include
• Letter motivating the application and background for this position
• Diploma and transcripts of records (BSc and MSc)
Please submit your application electronically in German or English, as one PDF file.
The successful candidate will be employed under a regular employment contract.
The position is to be filled at the earliest possible date and offered for a fixed term for initially one year.
It is planned to extend the contract for another two years.
The fixed-term employment is possible as it constitutes one of the fixed-term options of the Wissenschaftszeitvertragsgesetz (German Act on Fixed-term Scientific Contracts).
This is a part-time contract position.
The standard weekly hours will be 26,55 hours.
The successful candidate has the opportunity to pursue a doctoral degree in this position.
The salary is based on the German public service salary scale (TV-L).
The position corresponds to a pay grade of EG 13 TV-L.
