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...

Understanding diffusion of molecules or nanoparticles in pores is critical for the design of chemical reactions as well as separation processes by chromatography, adsorption, or porous membranes. Our group contributed to a recent paper that resulted from a broader collaboration within the Collaborat...

Advanced measurement techniques for diffusion coefficients pave the way to a better understanding of diffusion in chemical processes. In an open-acess paper by Wenchang Wu et al. from the Institute of Advanced Optical Technologies – Thermophysical Properties (AOT‑TP), diffusivities of polyethylene g...
