*********************************
There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

"Micro/Nano Mechanics and Photonics for Biomedical Applications"
Nanostructuring of atomically-thin two-dimensional (2D) materials (e.g. graphene and MoS2) has showed promise to create new functionalities for various biomedical applications, especially flexible and wearable electronics. In this talk, I will discuss how nanostructuring of atomically-thin materials could create new functionalities based on the fundamental studies of mechanics and photonics at nanoscale. I will first discuss how nanostructuring of atomically-thin 2D materials allows for the enhancement of their exceptional material properties and creating new functionalities in mechanical, optical, plasmonic properties. I will also introduce a shrink nanomanufacturing method developed based on nanoscale mechanics of atomically-thin materials, including graphene and MoS2 atomic layers. Shrink nanomanufacturing allows large-scale, uniform crumpling of graphene, a two-dimensional (2D) material, enabling mechanical stretchability and strain tunability of a flexible optoelectronic device. I will highlight a high-performance flexible photodetector developed based on the shrink nanomanufacturing approach as well as its potential in flexible/wearable optical sensing technology for biomedical applications.
Lunch will be served at the beginning of the seminar.
