 Research efforts in the Department of Nanoscale Science, directed by Klaus Kern, are centered on nanometer-scale science and technology with a focus on the bottom-up paradigm.The aim of the interdisciplinary research at the interface between physics, chemistry and biology is to gain control of materials at the atomic and molecular level, enabling the design of systems and devices with properties determined by quantum behavior on one hand and approaching functionalities of living matter on the other hand.The Lotsch department employs modern techniques of nanochemistry and combines them with classical methods of solid-state synthesis to develop materials with complex property profiles, including two-dimensional systems and layered heterostructures, porous frameworks, photonic nanostructures, and solid electrolytes for applications in (photo)catalysis, sensing, and solid-state batteries.
