Curriculum Vitae<\/h2>\n\n\n\n

Andreas Walther (*1980) is a Professor for Functional Polymers at the Institute for Macromolecular Chemistry at the Albert-Ludwigs-University in Freiburg (Germany).<\/p>\n\n\n\n

His research interests concentrate on developing and understanding hierarchical self-assembly concepts inside and outside equilibrium, and on using them to create Active, Adaptive and Autonomous Bioinspired Material Systems – A3BMS.<\/p>\n\n\n\n

He graduated from Bayreuth University in Germany in 2008 with a Ph.D. focusing on the self-assembly behavior and applications of Janus particles and other soft, complex colloids. After a postdoctoral stay with a focus on biomimetic hybrid materials at Aalto University (Helsinki, Finland), he returned to Germany (2011), and established his independent research group at the DWI \u2013 Leibniz Institute for Interactive Materials in Aachen. In 2016 he was appointed to his present position in Freiburg.<\/p>\n\n\n\n

A. Walther has published close to 130 papers (h-index 44) and has recently been awarded the Bayer Early Excellence in Science Award (for Materials), the Reimund Stadler Young Investigator Award of the German Chemical Society, a BMBF NanoMatFutur Research Group, and an ERC Starting Grant. He is a fellow of both the Freiburg as well as the Strasbourg Institute for Advanced Studies.<\/p>\n\n\n\n

    Implementation of Light-Powered Nanomachines into Polymer Bulk: From Fundamentals of Active Matter to Functional, Life-Inspired Polymer Materials<\/strong><\/strong>.<\/h3>\n\n\n\n

    Since they work far from thermodynamic equilibrium, biological systems exhibit active and adaptive functionalities that surpass the passive properties of present-day synthetic materials. Molecular machines are at the core of such biological out-of-equilibrium systems, and transduce energy (e.g. light, chemical) into mechanical motion and produce functions (e.g. transport, movement) from their mechanics. Our long-term vision is to develop concepts for the integration of artificial nanomachines into polymer bulk materials and develop the field of far-from- equilibrium, active polymer bulk materials (\u201cactive plastics\u201d) \u2013 which would result in an entirely new class of life-like materials. This includes in particular to (i) realize a synthetic integration of light-powered nanomotors (capable of rotating at MHz frequency in unconstrained environment) into purposefully engineered polymers, (ii) understand the fundamental operational principles by a systematic study, and (iii) capitalize on this understanding with a first material implementation in the framework of light-adaptive mechanical high-performance biomimetic nanocomposites, inspired by the structure in mother-of-pearl. To tackle the underlying interdisciplinary challenges, we merge our expertise in a coherent research program on several levels: molecular machines, organic and supramolecular chemistry, macromolecular engineering, polymer physics, advanced characterization, materials science and non-equilibrium active matter.<\/p>\n\n\t\t\t<\/div>\n\t\t<\/div>\n\t<\/div>\n<\/section>\n\n\t<\/div>\n<\/article>\n<\/div>\n<\/div>\n\n\n\n
