Doctoral student / Academic staff member (f/m/d)
for the production of cluster- and nanoparticle-based model catalysts (75% part-time)

Category

Job description

The project is part of the Collaborative Research Center "Tracking the Active Site in Heterogeneous Catalysis" (CRC 1441 TrackAct), funded by the German Research Foundation (DFG). The goal is to better understand the relationship between the structure and properties of catalysts used in emission control. To this end, you will synthesize atomically precise precious metal clusters and monodisperse nanoparticles with tunable size, shape, and composition, which you will then use as building blocks for the production of defined model catalysts. Based on catalytic tests and in-depth structural characterization, you will derive structure-property relationships for reactions in the field of emission control to develop improved catalysts with low precious metal content in the future.

Your tasks will include:

• Development of novel synthesis processes for precious metal clusters/nanoparticles in the liquid phase.
• Production of model catalysts using the precursor concept.
• Characterization of the prepared clusters, nanoparticles, and model catalysts.
• Applying the synthesized catalysts in catalytic tests in collaboration with project partners.
• You will present your results at national and international conferences and contribute to publishing the research results.

The position offers the opportunity for part-time doctoral studies.

Personal qualification

You have:

• You have a completed university degree (Master's / Diploma (University)) in chemistry or a related discipline with excellent grades.
• You show a strong interest in scientific work and you want to pursue a doctorate.
• You have a strong background in inorganic chemistry, with in-depth knowledge and experience in chemical synthesis and characterization methods.
• You are experienced in working under inert gas conditions and handling air-sensitive / pyrophoric substances, and in laboratory safety regulations.
• Experience with chemical analysis techniques (e.g., IR, UV-Vis, and NMR spectroscopy, powder diffraction, electron microscopy) is desirable.
• Fluent English skills (written and spoken) are required, and knowledge of the German language is highly desirable.
• You have a collaborative mindset to work in a team and with interdisciplinary project partners.

PhD Student Position (f/m/d)
Continuous Hydrothermal Synthesis of Magnetic Nanoparticles for Application in Additive Manufacturing of Functional Materials (75% part time)

Category

Job description

Continuous hydrothermal synthesis in near- or supercritical water (scH₂O 374°C, 22.1MPa) enables the production of highly crystalline particles in a sustainable and environmentally friendly reaction medium. Nanoparticles made of magnetic materials exhibit interesting magnetic properties that depend on their size, shape, and structure. These particles have great potential for various applications in the biomedical and technical fields. As part of the project, you will develop processes for continuously synthesizing highly crystalline, tailored magnetic ferrite nanoparticles with special magnetic properties in supercritical water (scH₂O). Particle formation under scH₂O conditions is still poorly understood. Therefore, in cooperation with our project partner, you will monitor the synthesis process in-situ by implementing sensors for electrochemical impedance spectroscopy. The magnetic nanoparticles will be implemented in 3D-printed functional materials (polymer composites). 

Your tasks will include:

• Adapting an existing continuous hydrothermal synthesis plant.
• Developing processes for continuously synthesizing magnetic ferrite nanoparticles under near-critical and supercritical conditions.
• Optimizing the process parameters.
• Carrying out kinetic investigations.
• Characterizing the properties and structure of the magnetic nanoparticles.
• Functionalizing the surface of the nanoparticles for integration into 3D-printed, functional polymer composites.
• You will work in a team with our project partner.
• You will present your results at national and international conferences and contribute to publishing the research results.

Personal qualification

• You have a university degree (Master's degree or equivalent) in (technical) chemistry, chemical engineering or related disciplines with excellent grades.
• You show a strong interest in scientific work and you want to pursue a doctorate.
• You have a strong background in technical chemistry, inorganic chemistry, and chemical synthesis.
• Expertise in chemical analysis techniques (e.g., powder diffraction, electron microscopy, IR and Raman spectroscopy) is desirable.
• Experience with high-pressure technology and electronic components, as well as programming skills, is beneficial.
• Fluent English skills (written and spoken) are required, and knowledge of the German language is highly desirable.
• You have a collaborative mindset to work in a team and with interdisciplinary and international partners.
