Particle-Based Materials Symposium

The particle based materials symposium aims at bringing together scientists and engineers from different communities to share their knowledge and to create functional materials using particles of all sources. The 4th symposium hosted in Ulm covered synthesis, processing, and materials integration of particles into thin films, bulk matrices, fibers, and other scaffolds. Andrea and Chen from our group got the opportunity to participate at the symposium to present their works on confinement assembly and cascade catalysis and had interesting discussions with the other participants.

Zsigmondy Award of the German Colloid Society

The 49th Conference of the German Colloid Society took place at Uni Stuttgart from 23.09.-25.09. with the topic “Complex fluids”.
Andre gave an award lecture for receiving the Zsigmondy Fellowship 2019, which is awarded to early career researchers in a two-year cycle.
He is very happy and honored that the work of his group was acknowledged with this award.

Reimund Stadler Award 2020

Every two years, the German Chemical Society/Macromolecular Chemistry invites a small number of talented early career researchers to the Early-Career-Researcher Workshop for talks and discussions.This year, the two-day workshop was organized by Evonik Industries in Chemiepark, Marl.
Out of the 12 competitive high-quality lectures, Andres presentation on “The many faces of ABC triblock terpolymers” was nominated by the committee for the Reimund Stadler Award 2020. This award is a particular honor for Andre, as Reimund Stadler is widely accepted as the pioneer on ABC triblock terpolymer research.
The prize will be officially awarded to Andre next year on the annual meeting of the Macromolecular chemistry division of the GDCh.

ACS Fall 2019 National Meeting & Expo

ACS National Meetings are where chemistry professionals meet to share ideas and advance scientific and technical knowledge. By attracting thousands of chemical professionals, the meeting provides excellent opportunities for sharing passions for chemistry, connecting with the world’s largest scientific society, and advancing your career in this ever-changing global economy. This national meeting in San Diego, California was all about chemistry & water. Our PhD students Andrea and Steffi had the chance to present their recent results during talks.

15th Zsigmondy Colloquium 2019

Steffi presented her recent results at the Zsigmondy colloquium 2019 in Dresden, Germany. This Colloquium covered synthesis of colloidal particles and their multiscale assembly as well as the optical/electronic properties of those assemblies with focus on adaptive/functional materials. The Zsigmondy colloquium aims at younger researchers at the pre- and post-doc levels in the field of colloid, surface and interface science. The goal was to foster communication between researchers from universities and other research institutions and industry.

Talk at Uni Wuppertal

André followed an invitation to visit the group of Prof. Uli Scherf at the University of Wuppertal.
He also gave a presentation about photonic micelle solutions and block copolymer self-assembly.

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.


Lecture at TUM

The Chemical Society of Munich invited André to participate in the Evonik Science Pitch and to give a lecture on "How to form complex colloids with unusual shape, surface, and inner structure" at the Technical University of Munich (TUM). Andre met with several groups for discussions, including also Job Boekhoven who has become well-known for his work on supramolecular and dissipative self-assemblies.

Beer, pretzels and braten after the talk.


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.

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.

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.
