We are happy to share our recent open access paper 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 homolo...

We are pleased to announce our new open access work on using chromatography for producing highly defined nanomaterials. Specifically, we developed a special operating mode, alternate pumping, for obtaining small, atomically precise glutathione-stabilized gold nanoclusters at high purity from synthes...

We are happy to welcome Johannes Wieczorek, M.Sc., in our group! Johannes Wieczorek studied Life Science Engineering at FAU. He is currently finishing his master thesis on Modelling and optimization of chromatographic processes for the isolation of pure PEG homologs under co-supervision of Malvina S...

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...

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...

Malte Kaspereit contributed to a chapter on Size Exclusion Chromatography (SEC) in the recently published collection book on "Particle Separation Techniques" (Ed. C. Contado). The chapter and the book can be accessed here: W. Peukert, M. Kaspereit, T. Hofe, and L. Gromotka: Size exclusion chro...

Malvina Supper and Malte Kaspereit gave oral presentations at the 35th International Symposium on Preparative and Process Chromatography (PREP 2022, May 15-18, 2022) in Baltimore (USA). Malvina Supper presented on "Model-based Development of Efficient Chromatographic Processes for the Isolation of ...
