SUMMARY:MEAM Seminar: "Architected Nanoscale Plates for Thermionic Energy Conversion and Relativistic Interstellar Travel"
DESCRIPTION:Architected plates feature geometrical patterns that provide advantageous mechanical properties\, such as an enhanced bending stiffness or a reduced tendency to tear. In this talk I will introduce our research group’s multiscale hexagonally patterned corrugated plates\, which have nano-scale film thicknesses\, micron-scale total heights\, and square-centimeter-scale lateral area dimensions. I will first explain how we use these plates in direct thermionic heat-to-electricity generators and show that new corrugation modalities provide several-fold reductions in the plates’ thermal conductivity\, leading to greater device efficiency. I will then show that our plates can be tailored to become ultra-reflective membranes for photon-propelled space travel near the speed of light\, and explain mechanical guidelines for the design of relativistic light sails.
