Experimental Soft Matter Physics


to the web site of the Experimental Soft Matter Physics group, led by Prof. Jan Lagerwall, at the Physics & Materials Science Research Unit of the University of Luxembourg. We are interested in all fascinating aspects of soft matter (and they are indeed many!), most of our research activities dealing with liquid crystal formation in one way or another. This is the reason for our domain name. Our main foci are on nano- and microscale self-assembly processes in colloids, liquid crystals and polymers and their applications in innovative contexts, currently mainly in wearable technology and soft robotics.

From September 2010 to February 2014 the group was called the Soft Nano- & Microstructures Group and it was located at the Graduate School of Convergence Science and Technology, Seoul National University, Suwon, Korea. The group started out as the Liquid Crystals and Nanocomposites Group in Halle, Germany, at the Martin-Luther-Universität Halle-Wittenberg, Institute of Chemistry - Physical Chemistry, its home from September 2007 to August 2010.
