Abstract:

Thermal transport can be significantly influenced by the presence of nano- and mesostructures and the interfaces that exist in such materials. This structuring can be employed to realize super-insulation properties as well as efficient heat spreading. Consequently, nanoscale thermal transport has attracted a lot of research interest for the past 20 years. Furthermore, (colloidal) mesostructures play a pivotal role in light-matter interaction, covering a broad spectral range from ultra-violet to mid-infrared. Thus, solar radiance scattering and thermal radiation emission can be tuned towards passive radiative daytime cooling.

In this presentation, I will provide an overview of heat transport and heat management in mesostructured materials. Based on anisotropically structured materials on different length scales and dimensionalities I will highlight the vast possibilities to control the temperature distribution for various applications. Order and disorder further contribute to thermal transport pathways and scattering of light. Colloidal mixtures of distinct compositions are well-suited model systems to systematically unravel their role in heat management. Finally, we have a strong interest in materials with a gradient structure. I will demonstrate various pathways to access gradually structured materials and how they can be employed for optical engineering and switchable temperature gradients.

Short bio:

Prof. Markus Retsch earned his degree in Polymer and Colloid Chemistry from the University of Bayreuth in 2006. Following this, he pursued his Ph.D. at the Max-Planck-Institute for Polymer Research in Mainz, focusing on colloidal assembly structures. He completed his Ph.D. at the Johannes Gutenberg University in Mainz in 2009 before spending 2.5 years as a postdoc at MIT. In 2012, he became a Junior Professor for Polymer Systems at the University of Bayreuth. Dr. Retsch has received prestigious honors, including a Lichtenberg professorship in 2013 and an ERC Starting grant in 2016. Currently holding the chair for Physical Chemistry I at the University of Bayreuth, his research centers on mesostructured materials for energy conservation and conversion, utilizing innovative colloidal assembly strategies. He also serves as vice-dean of the Faculty of Biology, Chemistry, and Earth Sciences, and deputy spokesperson of the CRC1585 “MultiTrans”.
