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 dr. Mishra!

On Friday, October 28th, Kartikeya Mishra successfully defended his PhD thesis entitled “Electrically tunable optofluidic lenses: fabrication and characterization”. In his thesis Kartikeya describes the possibilities to shape fluid lenses by applying electric fields. If you do that in the right way al kind of lens aberrations can be minimized or even completely suppressed. ... read more
