Sorry for my sending a second reminder. [cid:image001.jpg@01D7B05B.E6748F30] 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. Ryan Wagner Research Assistant Professor, School of Mechanical Engineering September 23rd, 2021 | 12:00pm Join Zoom: https://purdue-edu.zoom.us/j/98695180597 [cid:image004.jpg@01D7B05F.BA28D9A0]Title: Vibrations and mechanics applied to Multiphysics problems in MEMS, Manufacturing, and Microscopy Abstract: At the macroscale, microscale, and nanoscale vibrations and mechanics can be exploited for metrology in process monitoring, system design, and diagnostics. In this talk, I will discuss three vibration and mechanics based metrology problems across these three length scales. At the macro-scale, roll-to-roll systems enable scalable manufacturing of flexible electronic devices. The magnitude and distribution of web tension can have a significant effect on device yield and performance. To address this, we have developed a vibration-based metrology system for measuring the tension distribution within the web substrate. At the microscale, microcantilever-based radio frequency capacitance switches are an important MEMS device. Stiction failure, where the cantilever becomes stuck to the dielectric surface is an important failure mode. We used the Atomic Force Microscope (AFM) as a surrogate system for studying the dynamic detachment of a microcantilever from a surface. This is a possible recovery mechanism for fixing failed devices. At the nanoscale, the detailed modeling of viscoelastic contact mechanics is important for simulating the interactions between an AFM cantilever tip and soft, viscoelastic surfaces. Commonly employed models for this are often ad-hoc in nature leading to inconsistent predictions of surface behavior. We have developed a computationally improved implementation of Attard’s model, a rigorous first principles contact mechanics model that enables accurate prediction of surface dynamics for soft, viscoelastic materials. We have deployed this model in our online AFM simulation tool VEDA, which is found on nanoHUB.org. Bio: Ryan Wagner is a Research Assistant Professor in the School of Mechanical engineering at Purdue University. He received his B.S. and Ph.D. both in Mechanical Engineering from Purdue in 2008 and 2014 respectively. His graduate research topic was the application of AFM to study the mechanics of cellulose-based nanomaterials. Ryan was awarded a National Research Council postdoctoral fellowship at the National Institute of Standards and Technology where he worked on AFM metrology and cavity optomechanics. After this postdoc, Ryan was employed as a Research and Development Scientist at Asylum Research, an AFM instrument manufacturing company. Ryan’s research interests include metrology, microscopy, interferometry, spectrometry, vibrations, and dynamics.

[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.

Hello It is my great pleasure to announce a webinar by Mr. Jim Watson (Watson Associates) on "The Communication Connection". Please see the details attached and below. This webinar is mainly meant for the graduate students, but all are welcome to join. [The Communication Connection(c) Mr. Jim Watson Watson Associates Thursday, September 16, 2021 10 AM-11 AM * https://purdue-edu.zoom.us/j/3164232249 Abstract Although our profession is based on the application of technology, we must also apply effective non-technical skills to be successful. One of the most important non-technical skills is communication. This includes reading, writing, listening, one-on-one conversations, group and team discussions, presentations to peers, and formal project presentations to senior management, clients, and others. This talk will cover different aspects of written and oral communication and will present some guidelines to effectively convey one's message. Please see the attached pdf document for details, which Mr. Watson has requested to be shared with the audience. Bio Please see the attached document.

Webinar by Prof. Mahdi Hosseini (Purdue) on "From Shannon’s Bit to Bennett’s Qubit"
by Gupta, Sumeet Kumar 02 Sep '21

02 Sep '21

>From Shannon’s Bit to Bennett’s Qubit How to build fundamentally secure communication networks and exquisite imaging systems using quantum light? Prof. Mahdi Hosseini Purdue University Thursday, September 9, 2021 10 AM-11 AM • https://purdue-edu.zoom.us/j/3164232249 Abstract Single optical or atomic particles can exhibit quantum properties with fundamentally interesting behavior. The transition from single-particle to many-particle quantum systems is a realization limiting many real-world quantum applications. In this talk, I will provide an introduction to quantum optical information and its application in secure communication and imaging. I will describe our experimental research in two areas of quantum communication and quantum imaging. I will show that by implanting arrays of ions into micro photonic devices, we can engineer light-atom interactions to harness collective and coherent light emission and absorption. I will also present some of our preliminary work in developing new multi-mode quantum light sources tailored for quantum imaging applications. I will also briefly introduce some of our new efforts in the areas of quantum programming and quantum education. Bio Mahdi Hosseini is an Assistant Professor of Electrical and Computer Engineering at Purdue University. He completed his Ph.D. and postdoctoral studies at Australian National University (2012) and Massachusetts Institute of Technology (2016), respectively. He joined Purdue in Aug 2016. His current research projects include developing cryogenic quantum optical memories and rare earth nanophotonics for quantum communication and developing room-temperature light-atom interfaces for quantum optical imaging and sensing.
