The Vogel Lab

We are happy to launch our new webpage: vogellab.de It will provide: information about lectures, news about recent publications, highlights from the lab, (soon) a (popular) science section, current open positions, and our brand new particle and monolayer shop 👩‍🔬🏐🦋

Why does the hydrophobicity of nanogels influence whether oil-in-water or water-in-oil emulsions are stabilized and how can it be predicted? Find out more in our last paper in collaboration with @klinger_lab pubs.acs.org/doi/10.1021/ac…

This method is reported in: J. Wang, S. Hahn, E. Amstad, N. Vogel, Tailored Double Emulsions Made Simple. Adv. Mater. 2022, 34, 2107338. doi.org/10.1002/adma.2…

Double emulsions are great for many different experiments, but their fabrication is challenging, right? In this video-tutorial, we show you how to make well-defined single-core double emulsions in the simplest possible way, following only a few easy steps. youtube.com/watch?v=NTkTOa…

Johannes won the best presentation award at the “Particles at Liquid Interfaces” conference. Hooray and congratulations, Johannes!

Clean up after your experiments! What helps in the lab is even more important in the real world! We show how we can remove colloidally stable submicron-particles from wastewater by a synergetic combination of electrophoresis and particle-stabilized foams.

In out last paper on @ChemCommun we propose a new inverse opals sensing concept, which does not rely on a change in the proprieties of the wetting liquid but on changes to the surface upon binding of the analyte. This method will allow to expand the range of molecules detected!

Prof. Vogel (@VogelLab) explained the origin of color during the opening of the exhibit “Schillernd Schön” at the #Bionicum Nürnberg. The team of CRC1411 complemented the beautiful pictures of Thomas Büchsemann with a video 🦋and with lab-made structural color materials.

Die Farben der Natur faszinieren das @VogelLab @UniFAU und den Fotografen Thomas Büchsemann. In der Ausstellung “Schillernd schön” im #Bionicum treffen Forschung und Kunst aufeinander. Zur Eröffnungsfeier hat Prof. Vogel Regenbogenschokolade dabei!🤩@SNSB_Aktuell @museen_nbg

Researchers @VogelLab mimic nature’s striking colors using colloidal photonic crystals containing polydopamine. Polydopamine, a synthetic analog of natural melanin, removes scattered light, enhancing light-matter interaction. Learn more: ow.ly/az0750REtpa

These findings underscore the significance of absorber integration, offering efficient methods for preparing colloidal photonic crystals with saturated structural colors.

Chromaticity analysis in the L*a*b* color sphere reveals structures with optimal color saturation. Simulations suggest that homogeneous absorber distribution is most efficient, yet heterogeneous incorporation outperforms it, allowing for precise adjustment of absorber content.

Carina's and Gudrun’s recent article has been featured on the cover of Advanced Materials Interfaces! In this paper, we demonstrate how to enhance optical effects by integrating Polydopamine (PDA), a synthetic melanin, into photonic crystals. PDA is incorporated in two ways 1/n

1- gradually increasing PDA shells in core-shell particles, maintaining a constant total diameter, to create homogeneous crystals, and co-assembling varying ratios of polystyrene (PS) and 2- absorbing PS@PDA particles for heterogeneous crystals.

Last Monday Niki presented how structural color works at the science slam "Um uns die Nature" organized by the Senckenberg Gesellschaft für Naturforschung and the Frankfurter Museums-Gesellschaft e.V. at the Opera house in Frankfurt and won the second Prize for his presentation!

Our Master Student Sonja won the🥇 first prize 🥇 for her poster "Determining the Organization of Binary Colloidal Supraparticles by matters of Diffusiophoresis and Channel Formation” at the Spray Drying Symposium Würzburg. 🤹‍♀️We are very proud of her achievement!🎉🎉

Are you passionate about climate change? Then join the event organized by Bionicum at the Planetarium in Nuremberg on April 26th for exciting presentations and discussion on the topic!

@M_Sobhkhiz International students are also encouraged to apply!
