Season's Greetings

24 Nov '21

Dear All, As the year is coming to close, we reflect on unprecedented events that have impacted all of our lives. This is a difficult situation with self isolation and physical distancing, especially for many of our international students and researchers who are thousands of miles away from their families. There are some who have been personally impacted with the loss of family members and millions who are in economic hardship. During these difficult times, we appreciate unique gifts and contributions from each member of our community. We are fortunate to have dedicated students, staff and faculty who went out of their ways and regular responsibilities to help each other. We managed to keep Birck operational for critical research between April and June. Our dedicated staff and faculty developed standard operating procedures for all labs and cleanroom that are shared by more than 500 users across campus. Thanks to everybody who has been careful and extra vigilant, we had a smooth operation during the Fall semester. We would like to thank everybody's great contributions and hope you will have safe and healthy end of the year holidays and best wishes for the New Year 2021. Sincerely, Ali, Zhihong and Sunil [cid:image002.png@01D6D3A2.91AE72E0]

FW: BNC Faculty Seminar Series: Speaker - Thomas Beechem - September 16th | 12noon | via Zoom

13 Sep '21

[cid:image004.jpg@01D685C0.EB336F80] The BNC Faculty Seminar Series is designed to provide faculty a platform to present an overview of their research and the opportunity for collaborative discussion with other BNC faculty and researchers across six colleges and 15 academic units. Thomas Beechem Associate Professor, School of Mechanical Engineering September 16th, 2021 | 12:00pm Join Zoom: https://purdue-edu.zoom.us/j/98695180597 Title: Fusing Light with Heat Thermal Physics for Nanophotonics & Vice Versa [Thomas Beechem]Abstract: Light exhibits a wave nature. Phonons do too. Within the infrared portion of the spectrum, these differing "waves" can interact to form hybrid energy carriers called polaritons. Polaritons, in turn, provide fundamental advantages for optical functionality and thermal transport. Here, means of capitalizing upon these advantages will be explored. First, the necessity of creating alternative heat transport channels will be asserted by describing: (1) the generality of size induced reductions in thermal conductivity and (2) the inherently insulative nature of material boundaries on transport. Polaritons-and our ability to engineer them-will then be shown amenable to meeting these challenges. Specifically, polariton dispersion engineering will be demonstrated via an examination of actively tunable infrared metasurfaces leveraging voltage-induced changes in the optical properties of graphene and lead zirconate titanate (PZT). Building from the ability to tailor dispersion, future directions will be described highlighting means of implementing polaritons to enhance not only nanoscale thermal transport but also infrared sensing and spectroscopy. Bio: Thomas Beechem joined the faculty of Purdue University's Mechanical Engineering Department in August of 2021. Beforehand, he was a scientist at Sandia National Laboratories in Albuquerque, NM for 12 years where he held an affiliate appointment with the Center for Integrated Nanotechnologies (CINT). Thomas now leads the Specere Laboratory at Purdue, which focuses on leveraging nanoscale phonon-physics to create thermal, spectroscopic (i.e., sensing), and infrared solutions. He has authored more than 85 archival publications, holds 5 patents, and had his work selected as the featured "cover article" on 5 separate occasions by 6 different periodicals. He received a 2015 Defense Program Award of Excellence and was named one of Sandia's "Up and Coming Innovators" in 2016. In 2017, he was named an associate editor for the Journal of Heat Transfer, a role that he remains in today.
