Kurzbeschreibung: In this Master Thesis, your work will be mainly concentrated on the development of novel and functionalized α-diimine Ni complexes to catalyze ethylene polymerization. Through careful design involving systematic varia-tion of ligands of the α-diimine Ni complexes, you will be able to tune their catalytic behavior and the final polymer property.

Beschreibung: The catalyzed polymerization will be run and optimized under different reaction conditions, including the co-catalyst molar ratio, temperature, pressure, and time. High temperature GPC, NMR, and DSC will be used to evaluate the exact property of the final polymers, such as the molecular weight, melting point and branching density. Hence, you will work collaboratively with other team members to learn and discover the method to syn-thesize the new α-diimine ligands/ complexes, and run ethylene polymerization.

Project description:
4D printing of stimuli sensitive polymers has the potential to introduce additional functionalities to a wide variety of practical applications and further to fabricate customized functional devices. Within this project photopolymers are developed comprising stimuli sensitive groups that change the network structure, network density, (thermo-)mechanical properties but also surface properties in response to external trigger. Taking advantage of the high reactivity and excellent mechanical properties, 3D printed stimuli sensitive polymers will be based on photopolymerization of (methyl-) methacrylates as well as on “click” chemistry, suitable for DLP (digital light processing) based printing processes. Advancing from investigations of 2D photopolymers, complex 3D architectures with smart functionality (e.g. self-healing, shape memory, etc.) will be manufactured by employing additive manufacturing techniques. The smart functionality based on stimuli-triggered dynamic bond cleavage and formation mechanisms of the polymers will be investigated and the potential and limitations of the designed architectures for different transformations (e.g. gripping of objects) and applications in soft robotics will be evaluated.

We provide
✓ Advanced research in a multi-disciplinary team
✓ Excellent contacts to industry as well as to national and international research organizations
✓ Additional educational program involving training schools, workshops and summer schools
✓ Flexible working hours, 40h per week
✓ Possibility to perform a PhD at the Montanuniversitaet Leoben

At the Straubing Campus for Biotechnology and Sustainability at the Technical University of Munich, processes are being developed for sustainable and environmentally friendly chemical production. Due to the cross-industry and cross-disciplinary nature of the topic, experts from various disciplines work closely together on this. Modern biotechnological methods play a central role in this process.

We are looking for a Research Assistant / Doctoral Student (m/f/d)
for a European research project (PERFECOAT) on the Development and modification of biopolymers (exopolysaccharides) for paint applications.
Within the work the following areas will be addressed:
– Enzymatic and chemical functionalization of exopolysaccharides (EPS)
– Optimization of isolation and purification processes
– Structural and application-related product characterization

Your profile:
– Above average successfully completed university studies in the fields of chemistry, material science, biochemistry, biotechnology or similar
– Solid experience with work in organic chemistry or polymer chemistry
– Ideally, you have experience with polymer analogous reactions and polymer analytics
– Interest and experience in biocatalysis, enzyme engineering or fermentation is a plus
– Curiosity and interest in scientific issues
– Fluent in English, both orally and written. German is a plus, but not mandatory.
– High level of commitment as well as teamwork and communication skills

We offer:
– An interdisciplinary scientific challenge in an applied environment with exposure to academic and industrial partners across the EU
– Salary according to TV-L, E 13, part-time (65 %). The employment is limited to 3 years.
– There is the possibility of a stay abroad.
– As a TUM doctoral student, you are automatically a member of the TUM Graduate School. You will benefit from a comprehensive qualification and further education program, mentorship, funding for travel abroad as well as target group-specific services and consulting offers.
– Severely disabled applicants will be given preference if their suitability is otherwise essentially equal.

The Technical University of Munich aims to increase the proportion of women in its workforce, and therefore expressly welcomes applications from women.
