We wish you a successful start into the new semester and especially to all new students, the best of luck and an exciting time. Remember, even after the orientation week, we always have an open door and are pleased to help you.

Understanding the complex entanglement between structural and dynamical properties of glasses is a great scientific challenge. A powerful technique to study such relations on a microscopic scale is microrheology, where one analyzes the translational dynamics of an externally driven probe particle. Here we experimentally investigate the mechanical properties of a colloidal glassy system by measuring simultaneously the translational and the rotational dynamics of an embedded active, i.e. self-propelled, probe particle (APP), whose orientational motion is unconstrained. We find that its rotational diffusion coefficient continuously increases towards the glass transition and drops down in the glassy state. Such unexpected behavior demonstrates a strong coupling mechanism between the APPs orientation and the glassy structure, which is in excellent agreement with a simple rheological model. Our results suggest the use of APPs as an efficient and versatile method to measure the micromechanical response of complex materials.
In the 21st century nanotechnology is the technology of the future and “nano” is the subject of research at the Department of Physics in Konstanz. The world of the very small is dominated by exotic principles of quantum physics where ordinary materials show novel and surprising properties. Also, light is a quantum phenomenon and much of its nano properties are still not well understood. The insight to the laws in the nano-level allows producing novel materials with tailor-made properties.
On December 31, 2019 the SFB 767 - Controlled Nanosystems: Interaction and Interfacing to the Macroscale is coming to an end after 12 successful years. In the Final Symposium "Controlled Nanosystems" we will celebrate this era of nanoscience at the University of Konstanz together with former researchers and friends of the SFB.
The best teaching and excellent study conditions are very important to us. We constantly endeavour to improve and co-ordinate our lectures and courses and therefore believe in a close interlinking of experimental and theoretical content in the first semesters with two lecturers in one course and a constant harmonization with the laboratories. Small tutorials with a maximum of 12 students are our standard.
