From simple fluids to complex systems

The CRC offers a workshop to introduce rheological properties of fluids. The workshop will cover the range from simple fluids to complex systems. The workshop consists of four lectures with discussion and a general discussion in which CRC staff can ask their (project-) specific questions. The presenters will then be available to answer these questions. Dr Erik Wassner (Deputy Chairman of the German Rheological Society) was invited to speak at the event.

Team at TU Darmstadt uses Raman and NMR spectroscopy for measurements

How do substances in liquid mixtures behave during evaporation and how can evaporation processes be better controlled? A team at TU Darmstadt has made an important contribution to clarify these questions: The scientists have succeeded for the first time in contactlessly detecting different concentrations in mixtures. The results have been published in the renowned journal “Proceedings of the National Academy of Sciences” (PNAS).

Controlling droplet coalescence is an important requirement in microfluidics. In this context, “controlling” often means avoiding the undesired coalescence of droplets. One possibility is to use surfactants, but these are disadvantageous in a number of applications. CRC members Steffen Hardt and Johannes Hartmann, together with a colleague from their Nano- and Microfluidics group, have shown how it can be done without: they placed the droplets in a homogeneous electric field. The electric field redistributes charges in such a way that a repulsive force is created between two neighbouring droplets.

Pauline Brumm zu Gast bei KIT-Podcast „Modellansatz“

Der funktionale Druck stellt höhere Qualitätsanforderungen als klassische Verfahren. So müssen die häufig ultradünn gedruckten Schichten geschlossen, fehlerfrei und von konstanter Schichtdicke sein. Ein häufiger Druckfehler ist hier jedoch das sogenannte „Viscous Fingering“, eine hochdynamische Grenzflächeninstabilität bei der Fluidübertragung, die sich in Form von faszinierenden, verästelten Strukturen in der gedruckten Schicht bemerkbar macht. Es bedarf einer detaillierten Modellvorstellung des Druckprozesses, um klassische Verfahren aus dem grafischen Druck für den funktionalen Druck nutzbar zu machen. Im Podcast spricht Gudrun Thäter mit SFB-Mitarbeiterin Pauline Brumm über Benetzung im Tiefdruck.
