A recurring theme in our r esearch is the generation of hierarchical  structures on the molecular\, supramolecular\, nanoscopic\, and microscopic length scales. In this conte xt\, we attempt to mimic the way biological systems do not only accept the inevitable presence of disorder but even exploit it to obtain highly opt imized structure materials.\n\nWe control the placement of disorder on so me length scales\, use it to create structures on others\, and creates s tructural gradients between ordered and disordered domains to guide extern al fields. We have successfully implemented these concepts across very di fferent classes of materials and achieved. For instance\, we obtained orga nic nanowires that show an unprecedented photogeneration of charge carrier s at steady-state concentrations close to the insulator-metal boundary.\n\ nMoreover\, we prepared supramolecular elastomers that either show excelle nt elastic properties\, high stiffness\, and sharp melting transitions at high melting temperatures\, or result in high performance damping materia ls.\n\nFinally\, we used the nanoscale engineering of the order-disorder i nterface to create semiaromatic polyamides with excellent strength and sti ffness combined with a very high ductility. Hence\, our results show that better understanding the intricate interplay of order and disorder on diff erent length scales is crucial to design novel soft materials with unusual property profiles.\n\nProgram:\n\n-Introduction by Prof. Francesco Stella cci\, Director of the Supramolecular Nanomaterials and Interfaces Laborato ry\n-Inaugural Lecture of Holger Frauenrath: "Using order and disorder on different length scales to tailor the properties of soft materials"\n\nReg istration required: http://go.epfl.ch/frauenrath\n\nBio: Holger Frauenrath studied Chemistry at RWTH Aachen (Germany)\, where he also obtained his P hD in Polymer Chemistry in 2001. After postdoctoral research at Northweste rn University (Evanston\, USA)\, he started his own research at FU Berlin and later ETH Zurich\, where he obtained his Habilitation in 2009.\n\nHe s ubsequently started as a tenure-track assistant professor at the Institute of Materials at EPFL and received tenure in 2016. His research encompasse s organic semiconductor nanostructures\, hierarchically structured supramo lecular materials\, and functional carbon nanomaterials\, with an overarch ing focus on the role of the multiscale balance of order and disorder in s oft materials.\n  LOCATION:ELA1 http://plan.epfl.ch/?request_locale=fr&room=ELA1&domain=plac es STATUS:CONFIRMED END:VEVENT END:VCALENDAR
