Physics of Complex Fluids Group

The research goal of PCF is to understand and to control liquids and their interfaces from molecular to macroscopic scales. Our research connects fundamental phenomena in static and dynamic wetting, nanofluidics, microfluidic two-phase flow, functional surfaces, drop impact, and drop evaporation to practically relevant applications such as enhanced oil recovery, lab-on-a-chip systems, analytical chemistry (MALDI-MS), optofluidics, and inkjet printing.

Congratulations, Omkar, on your doctor title!

On Friday, January 16th, Omkar Deshmukh successfully defended his PhD thesis entitled “Soft Microgel Particles at Fluid Interfaces”. The work covers many aspects of the behavior of temperature sensitive PNIPAM microgel particles upon adsorption to air-water and oil-water interfaces. It highlights the prominent role of elastic deformations of these very open and soft gel networks that stretch by more than 100%, as Omkar revealed amongst other things by careful surface pressure measurement. The defense was attended live by Omkar’s larger family back in India and by his wife and son directly in Twente. We wish Omkar and his family all the best for the future. ... read more
