Guest Lecture - Dr. Arash Nikoubashman
Two Independent Emmy-Noether Research Group leader sharing ideas for combining theory and practice. André invited his collaboration partner and Emmy-Noether Research Group leader Dr. Arash Nikoubashman @Johannes Gutenberg University Mainz for given the audience a kind insight in his research field in statistical physics and soft matter theory. Nikoubashman’s group studies the fundamental principles of directed assembly of soft matter systems using advanced theoretical and computational methods. In particular, he focusses on the role of external fields on self-assembly, and the possibility to guide the building blocks into well-specified structures. Further, he investigates microfluidics of complex liquids and semiflexible macromolecules in confinement.

Goodbye to Katya
We are saying goodbye to our ErasmusPlus exchange student Katya from the Group of P. Petrov, Sofia (Bulgaria). The group combined her last day with a breakfast-group-seminar and a day full of activities at the Alma Sports Park, Gelsenkirchen.
The group say goodbye to Katya.
Summer Festival of Chemistry
Connecting is a key. At the summer festival of chemistry @Campus Essen Alex represented the group with a presentation about what we do, what we will do and recent publication highlights. After 15 presentations the groups get into talks by Bratwurst and beer.

Gust Visit: Jürgen Omeis - Altana AG
To connect the industrial side with cutting-edge university research Jürgen Omeis from Altana AG visited GröschelLab. Altana AG comprises the divisions BYK (coating additives and instruments), ECKART (metal effect pigments and metallic printing inks), ELANTAS (insulation materials for the electrical and electronics industries) and ACTEGA (coatings and sealant compounds for the packaging industry). During the day Alex, Andrea, Tai and Steffi represented the group with presentations and talks.

Guest Lecture - Prof. Dominik Wöll
During his session as chairman of the physical/ theoretical colloquium at the department of chemistry, André invited Jun.-Prof. Dominik Wöll (Insitute of Physical Chemistry @RWTH Aachen and head of high-resolution Fluorescence microscopy Applied in Molecular science and Engineering Competence center, FLAMENCO) to give a guest lecture about his research field in spectroscopy of condensed matter. Prof. Wöll focused in his talk on modern superresolved fluorescence microscopy methods such as dSTROM (direct stochastic optical reconstruction microscopy), PALM (photoactivated localization microscopy) or SOFI (superresolution optical fluctuation imaging) for in situ imaging compartmentalized microgels and microgel structures.

DPG Spring Meeting 2019, Regensburg
With round 6.000 visitors this year’s Spring Meeting of the German Physical Society (Deutsche Physikalische Gesellschaft e. V.; DPG) in Regensburg was Europe’s the largest physics congress on Condensed Matter. More than 5.000 papers and talks and presentations in the range from typically physical research questions, recent results in semiconductor physics, magnetism, surface science to questions of philosophy or the study of socio-economic systems were on the program. During the section of physical chemistry and polymer science with focus on morphology of complex polymer mesophases, organized by Kostas Daoulas and Prof. Volker Abetz, André was keynote speaker with his talk about building complex colloids with block copolymers and topology. André also chaired a session.

As part of the science podcast Methodisch inkorrekt!, Steffi and Alex had the opportunity to give a brief peek into our research field. The self-titled Rockstars of Science Dr. Nicolas Wöhrl and Dr. Reinhard Remfort started their podcast project in 2013. Until now they have produced over 130 episodes with topics related to science, scientific publications, noble and ig-noble prizes, and everyday life facts. In the interview, Steffi and Alex gave an overview about the concept of junior professorship, our research field in polymer science and hybrid materials, recent publications and group highlight e.g. the group trip to the Macromolecular Colloquium 2019 and ScientificNight Ruhr.

Macromolecular Colloquium Freiburg 2019
”Freiburg ist nur einmal im Jahr!“ This year, the entire group went to Freiburg to participate at the Macromolecular Colloquium 2019. The main topic of this year’s conference was “Polymers and the Digital Age” and about 1000 visitors ranging from national and international students, researchers and industry partners came together to discus recent developments in macromolecular chemistry. It was my pleasure to be part of this conference delivering a talk on Thursday. Overall, it was a packed trip with evening gatherings at Martins Bräu (continuing the tradition), talks, discussions, dinners and the dance floor of el.pi. The group made connections to other researchers like WaltherLab, WichLab, KlingerLab, BökerLab, WöllLab, LoosLab, SchacherLab, and many more, and gathered much experience at the biggest conference on Macromolecular Chemistry in Germany.

Block Copolymer Nanostructures Directed by Curvature and Topological Defects.
First Publication This Year: Angewandte Chemie
We report on the formation of shape- and surface-anisotropic Janus nanocups (JNCs) by evaporation-induced confinement assembly (EICA) of ABC triblock terpolymers. During microphase separation in spherical confinement, the triblock terpolymer spontaneously adopted a hemispherical shape with an inner concentric lamella-lamella (ll) morphology. Cross-linking and disassembly of the microparticles resulted in well-defined JNCs with different chemistry on the inside and outside. By synthesizing polymers with increasing length of the cross-linkable block, we tuned the mechanical stability of the nanocups, which is relevant to control opening and closing of the cup cavity.
