Congratulations Dr. Song... with assemblies of tiny cubes to his Ph.D. degree...

Qimeng successfully defended his Ph.D. thesis “Capillary Force-Driven Self-Organization of Microcubes for Multifunctional 3D Cell Microenvironments“ on July 5th 2019. In his thesis the central idea of the ERC project ASMIDIAS was finally realized in a massively parallel manner, exploiting self-assembly concepts at the water/air interface and applying this novel combinatorial approach for cell-surface interaction studies. Congratulations and all the best for your future!

Dr. Song with his hat

Nanoscience and Nanotechnology in Siegen in the focus.

Our research in PC-1 and that of our colleagues in the School of Science and Technology is highlighted in a recent video.

Great success for Nicole, Daniel, Stephan and Sergey. Our cover image was chosen for J. Colloid Interf. Sci. & finally the identification of surface nanobubble and differentiation from silicone oil nanodroplets is accomplished!

The conclusive answer as to whether the tiny spherical cap-shaped features on surfaces at the solid-water interfaces, which are easily imaged by AFM, are indeed surface nanobubbles or silicone oil nanodroplets has been finally resolved by our new combined AFM-FLIM (fluorescence lifetime imaging microscopy) approach. As reported in J. Coll. Interf. Sci. 2019, 547, 162–170. (Nicole Hain, Stephan Handschuh-Wang, Daniel Wesner, Sergey I. Druzhinin, and Holger Schönherr, “Multimodal Microscopy-Based Identification of Surface Nanobubbles”) the determination of fluorescence lifetime of a suitable tracer dye renders this possible for the first time with (a) high spatial resolution and (b) probing the gas-liquid interface. The cover page in J. Colloid Interf. Sci. (many thanks to Xiaoqiu Dou for instantaneous help with the graphics!) underlines the importance of the report and the great work of Nicole, Daniel, Stephan and Sergey. Congratulations!

"Schon mein Großvater kannte die Wirkung der Aloe vera und hat damit meine kleinen Wunden geheilt“, erinnert sie sich. Was die Chemikerin aus der Pflanze nutzen möchte, sieht aus wie ein aufgequollenes Gummibärchen: das Gel aus dem Wasserspeichergewebe der Blätter. In Kosmetika ist es schon lange ein wichtiger Inhaltsstoff. Goonoo will aus Bestandteilen des Gels und weiteren synthetischen Polymeren Fasern für ein Trägermaterial herstellen, das Zellwachstum unterstützen kann.

Katrin successful at the Leibniz Young Polymer Scientist Forum 2014 in Aachen

Congratulations to Katrin! She won with her group the "Award for the best presentation of how to approach future challenges in polymer sciences". The prize over 1000 Euros was given to a team of five junior researchers, including Katrin, in the award ceremony on August 28th 2014. The Leibniz Young Polymer Scientist Forum, organized by DWI and Evonik Industries in Aachen, is the place for young polymer scientists to meet and discuss important challenges in this fundamental field of research. The two-day event provided a forum both to sharpen current polymer scientific questions and to identify new challenges. Successful candidates for participation at the forum were selected from a larger group of applicants. At the Leibniz Young Polymer Scientist Forum, the young scientists attended focused workshops, shared their expertise and learned to be part of an interdisciplinary team.

POLYCHAR 20: IUPAC-Posterpreis für Sven Sidenstein

Bei der internationalen Fachtagung POLYCHAR 20 - 20th World Forum on Advanced Materials -, die vom 26. bis 30. März 2012 in Dubrovnik (Kroatien) stattfand wurde Sven-Christian Sidenstein, der zurzeit in der Physikalischen Chemie I seine Masterarbeit anfertigt, der IUPAC (International Union of Pure and Applied Chemistry) Posterpreis verliehen. In seinem Posterbeitrag "Internal organization does matter: Tracer-diffusion in poly(methyl acrylate) brushes and spin-coated films" (Mitautoren: Dr. Herbert Kneppe & Prof. Dr. Holger Schönherr) präsentierte Sven-Christian Sidenstein die Ergebnisse seiner Bachelorarbeit und erste Messergebnisse eines im Rahmen seiner Masterarbeit zusammen mit Dr. Kneppe konzipierten und realisierten Fluoreszenzmikroskopie-Experiments. Mit dem neuen Versuchsaufbau können die Rotation, Orientierung und Translation einzelner Farbstoffmoleküle in dünnsten Polymerschichten aufgezeichnet werden. Dabei standen neben der Synthese und Charakterisierung von sog. Polymerbürsten vor allem die Untersuchung des Diffusionsverhaltens von Farbstoffmolekülen in Schichten verschiedener Architektur im Fokus, sowie der Nachweis, dass tatsächlich die Rotation einzelner Farbstoffmoleküle als "Nanosonden" in seinem Versuchsaufbau mit hoher Zeitauflösung gemessen werden kann.
