Johannes Wieczorek received the 'Award for the best oral presentation' at the 20th Network Young Membrains Conference 2024 (NYM) in Prague, Czech Republic. The award is sponsored by the European Membrane Society. The NYM conference was co-organized by Dániel Gardenö from UCT Prague, who is a visitin...

Johannes Wieczorek gave a presentation at the 19th International Symposium on Preparative and Industrial Chromatography and Allied Techniques (SPICA) in Milan, Italy. SPICA is the most important event for scientists and developers from industry and academia who work in the field of preparative chrom...

Johannes Wieczorek presented our work on the chromatographic isolation of single homologs of polyethylene glycol (PEG) at the 14th European Congress of Chemical Engineering and 7th European Congress of Applied Biotechnology (ECCE/ECAB) held in September 2023 in Berlin/Germany. In his presentation, e...

We are very happy to announce that on July 20th, 2023, Jürgen Vargas Scnmitz successfully defended his PhD thesis 'Systematische Entwicklung adsorptiver Gastrennprozesse für Mehrstoffgemische'. During his research in our group, he developed a methodology for the systematic selection of experiments t...

In a recent open access paper we report on the isolation of individual homologs of polyethylene glycol (PEG) by preparative reversed-phase chromatography. Building upon a previously developed thermodynamic model, we were able to describe accurately the retention times of individual homologs based on...

We just published an exciting open access work where we present a new, very efficient chromatographic process for producing highly defined nanomaterials. Specifically, we devised a special two-column process, alternate pumping, for obtaining small, atomically precise gold nanoclusters at high purity...

For her poster "Development of Preparative Chromatographic Processes for the Isolation of Pure PEG Homologs", Malvina Supper received one of three "Best Poster Awards" at the 18th International Symposium on Preparative and Industrial Chromatography and Allied Techniques (SPICA 2022, Oct 11-14, 2022)...

A dedicated session was organized for the honor of Prof. Andreas Seidel-Morgenstern (Max Planck Institute, Magdeburg, Germany) at this year's AIChE Annual Meeting in Phoenix/Arizona (USA). The Area Plenary: Adsorption and Ion Exchange acknowledged the important contributions of Andreas Seidel-Morgen...

Malte Kaspereit (co-authors Malvina Supper, Lukas Gromotka, Wolfgang Peukert) gave a presentation entitled "Development of Preparative Chromatographic Processes for the Classification of Nanoparticles" at the 18th International Symposium on Preparative and Industrial Chromatography and Allied Techni...

In a new open-access publication, we present results of our long-lasting investigations on the chromatographic separation of polyethylene glycols (PEGs). Syntheses of polymers like PEGs always yield products with a distribution of molar weights. The broader such distribution, the less defined are th...
