Abstract: We study the fundamental mechanical and electrical responses of macroscopic assemblies of nano- and micro-structures, and we exploit this understanding to create experimentally novel materials and devices at different scales (for example, for application in thermal distance sensing, energy absorption and vibration mitigation). We design new materials controlling the nanoscale geometry during synthesis and fabrication processes. Different geometrical structures, used as fundamental building blocks, lead to different bulk material response that present "extreme" properties, not reported before in other natural or man-made materials. This talk will focus on the use of carbon nanotubes as fundamental building blocks for novel thermal sensors and as supper-efficient energy absorbing foams (see image enclosed). It will also discuss recent results in the dynamic characterization of 3-D micro-lattice materials for vibration absorption.

Bio: Professor Daraio research interests reside at the interface of materials science, condensed matter physics and solid mechanics, particularly in the design, development and testing of multi-scale metamaterials and phononic crystals. Prof. Daraio received a Mechanical Engineering degree from the Universita' Politecnica delle Marche, Italy (2001). She received her M.S. (2003) and Ph.D. (2006) degrees in Materials Science and Engineering from the University of California, San Diego. She joined the California Institute of Technology as an Assistant Professor 2006 and was promoted full professor in 2010. In 2013, she joined the department of Mechanical and Process Engineering at ETH Zürich, as a chair in Mechanics and Materials. She has been a guest researcher at the Lawrence Berkeley National Laboratories (NCEM), a visiting research physicist at the Scripps Institute of Oceanography (San Diego) and won several awards. Among these, she received a Presidential Early Career Award (PECASE) from the White House, was elected as a Sloan Research Fellow and received an ONR Young Investigator Award. Her work was featured in the John F. Kennedy Presidential Library and Museum in Boston and it has been highlighted in numerous broad media channels (CNN, NBC, Discovery Channel, NPR, etc.). She was also selected as one of the "Brilliant 10" by Popular Science magazine, won an NSF CAREER award and the Richard Von Mises Prize.
