But at the same time we want to remind our entire user group of the critical importance of following the COVID safety protocols while using our facilities. If an outbreak of COVID exposures should happen at Birck there is a real possibility that we may need to close the facility again. So please read and support the following….. …..Some of our approved users are holding the doors open for others to enter the building. This may very well be a gesture of politeness to assist another, but it also can be perceived that non-approved people are entering our building with the assistance of one of our approved users. Additionally it does not allow us to have an accurate accounting of who is entering our building by evaluating card-swipe data. So everyone should swipe into Birck and not be let in by someone holding the door open. …..Face masks are required while in Birck. Approved users have been, and continue to be, strongly encouraged to bring their own face mask for their personal use while in the facility. At the entrances we have supplied quantities of disposable face masks for emergency use, but our supplies of these disposable masks are being depleted at the high rate of 300 – 400 masks per week. This rate of use seems exceptionally high when personal masks are strongly recommended. Please only take one mask from the supply, and only when you’ve forgotten your personal mask. ….Social distancing continues to be a challenge. This is a difficult habit to develop and groups of people have been seen clustered around a tool, or having a hallway conversation, and not adhering to the 6’ spacing rule. Please continue to maintain at least 6’ spacing between yourself and the nearest other person. Please stay vigilant in promoting and supporting these safety protocols. If we each do our part we will continue to stay open and conduct state-of-the-art research in our great facility.

REMINDER: BNC Virtual Faculty Seminar Series: Speaker - Xiulin Ruan -TODAY Nov. 19th @ 12noon via Zoom

19 Nov '20

Reminder: BNC Virtual Faculty Seminar Series TODAY @ 12:00noon. [cid:image004.jpg@01D685C0.EB336F80] The BNC Virtual 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. Xiulin Ruan Professor, School of Mechanical Engineering November 19th, 2020 | 12:00pm Join Zoom: https://purdue-edu.zoom.us/j/93857631004 Title: Pushing Boundaries of Thermal Transport and Sustainable Energy: From First Principles Predictions to Scalable Applications Abstract: This talk will overview our recent innovations in thermal transport and sustainable energy, by pushing the boundaries ranging from fundamental first principles predictions to scalably manufactured systems. The first part of the talk will cover predictive first principles and molecular dynamics simulations of thermal conductivity and optical (or thermal radiative) properties. In particular, we establish four-phonon scattering as an unexpected significant mechanism affecting thermal conductivity of nearly all materials at high temperature, and 2D materials, low thermal conductivity materials, and certain high-thermal conductivity materials even at room temperature.1 In addition, four-phonon scattering can have significant or leading role in determining infrared optical properties of dielectrics.2 For complex crystals, the conventional phonon mean free path concept is insufficient, and we propose a two-phonon transport theory to better describe their thermal transport.3 We further show that machine learning can be used to dramatically accelerate the predictive design of energy nanomaterials.4 The second part of the talk will cover our development of the first commercial-like particle-matrix radiative cooling paint that can cool below the ambient temperature under direct sunlight.5 It is achieved via several approaches distinct from commercial paints: the use of the wide bandgap CaCO3 fillers, a high particle volume concentration of 60%, and a broad size distribution. Radiative cooling paints can have broad implications from saving energy to combatting climate change.6 The talk will close by exploring future directions and collaboration opportunities. 1.

[cid:image006.jpg@01D685C3.FA345960] Responding to COVID-19: Research Operations at Birck https://www.purdue.edu/discoverypark/birck/for-birck-users/covid/index.php Seminars /Workshops / Events BNC Virtual Faculty Seminar November 19th, 2020 | 12:00pm Xiulin Ruan, Professor, School of Mechanical Engineering "Pushing Boundaries of Thermal Transport and Sustainable Energy: From First Principles Predictions to Scalable Applications"<https://www.purdue.edu/discoverypark/birck/events/index.php?view=3142> Birck Events<https://www.purdue.edu/discoverypark/birck/events/index.php> and Birck News<https://www.purdue.edu/discoverypark/birck/news/index.php> Evaporator Update The Lesker and Leybold evaporators have been equipped with safety bar mechanisms to prevent the bell jars from falling when they're in the open position. The Lesker has been done for several days and the Leybold was completed last Friday. Short training sessions have begun to demonstrate the proper use of the safety bars. The Lesker is available for research for those who have had the safety bar demonstrations and the Leybold will be available after users are trained. The CHA1 is being retrofitted with a new hoist mechanism and will be returned to service in the next several days, and the new hoist for the CHA2 is being ordered this week. See Mike Bayless for Leybold safety bar training. Thanks for your patience as we improve the safety of our bell jar systems. Engineering Staff Birck Rule Change Dear Birck User Community, We've been re-evaluating the COVID restrictions that have been in place since we reopened our facility. We now have had several weeks of learning in our new environment and we are modifying two restrictions: 1. The 6:00 am - 10:00 am "staff-only" cleanroom restriction is being eliminated. Therefore effective immediately any authorized cleanroom user may enter the cleanroom at any time. Please continue to be mindful of the buddy requirement when working late at night or early in the morning..... namely do not do any acid processing without at least one other user in the cleanroom with you. 2. The gowning room capacity restriction of 3 people is being changed to 5 people. There can now be 5 individuals in the cleanroom gowning room at any given time. We hope this helps promote more efficient use of the gowning room while still maintaining the 6' social distancing requirement. While these changes are effective immediately we will change any signage in the next couple of days. Thanks for your cooperation and we will continue to evaluate our protocols as we move forward. The Engineering Staff Open Positions Research Internship Opportunity: Research internship is available with hourly payment of 15 $ per hour. The number of hours and timings are flexible. The research intern will conduct outdoor measurements and record data for machine learning applications. Juniors and senior undergrads with varied backgrounds in engineering and science are welcome to apply. The prospective candidate should have excellent academic credentials and an attention to detail to succeed in the project. Previous experience in engineering labs is necessary. The project is being conducted in the lab of Prof. Zubin Jacob (see www.electrodynamics.org<http://www.electrodynamics.org/>). Please contact Shree Hari Sureshbabu with your CV by Nov 30th 2020 (sureshbs(a)purdue.edu<mailto:sureshbs@purdue.edu>) Draper Labs: Looking to hire ASAP, high experience in fab. Applicants can be PostDocs, fresh PhDs or MS with experience. https://careers-draper.icims.com/jobs/4922/principal-mems--photonics-microf… EPFL's School of Engineering: currently has an open (junior faculty) position in Integrated Transducers, https://www.epfl.ch/about/working/faculty-position-in-integrated-transducer… and we are reaching out to the community to make colleagues aware of the open position and attract candidates. We aim in particular to increase the number of female faculty. Please spread the information in your network Birck Safety Protocols It is very gratifying to see our research community back 'in business' doing leading-edge research in our center after the long pause we all experienced this Spring. But at the same time we want to remind our entire user group of the critical importance of following the COVID safety protocols while using our facilities. If an outbreak of COVID exposures should happen at Birck there is a real possibility that we may need to close the facility again. So please read and support the following..... .....Some of our approved users are holding the doors open for others to enter the building. This may very well be a gesture of politeness to assist another, but it also can be perceived that non-approved people are entering our building with the assistance of one of our approved users. Additionally it does not allow us to have an accurate accounting of who is entering our building by evaluating card-swipe data. So everyone should swipe into Birck and not be let in by someone holding the door open. .....Face masks are required while in Birck. Approved users have been, and continue to be, strongly encouraged to bring their own face mask for their personal use while in the facility. At the entrances we have supplied quantities of disposable face masks for emergency use, but our supplies of these disposable masks are being depleted at the high rate of 300 - 400 masks per week. This rate of use seems exceptionally high when personal masks are strongly recommended. Please only take one mask from the supply, and only when you've forgotten your personal mask. ....Social distancing continues to be a challenge. This is a difficult habit to develop and groups of people have been seen clustered around a tool, or having a hallway conversation, and not adhering to the 6' spacing rule. Please continue to maintain at least 6' spacing between yourself and the nearest other person. Please stay vigilant in promoting and supporting these safety protocols. If we each do our part we will continue to stay open and conduct state-of-the-art research in our great facility.

REMINDER: JOINT ECE and BNC Virtual Faculty Seminar: Speaker - Krishna Jayant -TODAY, Nov. 12th @ 10:00am via Zoom

12 Nov '20

My apologies, today's seminar is at 10:00am. Reminder: BNC Virtual Faculty Seminar Series TODAY @ 10:00am. ECE and Birck Joint Virtual Seminar Krishna Jayant Assistant Professor of Biomedical Engineering November 12th, 2020 | 10:00am Join Zoom Meeting: https://purdue-edu.zoom.us/j/94730880530 Title: Nanoscale electrical and optical neurotechnologies for mapping the sub-cellular neural code Abstract: Single neuron computations span multiple scales - from synapse to dendrite to the soma. Mapping single neuron input-output electrical transformations as well as decoding their computational rules remains a central question in neuroscience and a key need for a thorough understanding of both microcircuit function as well as behavioral output. In this talk I will present both published and ongoing work in which we exploit multimodal approaches to address key challenges in the field of single neuron computation. In the first part of my talk, I will describe our work on mapping dendritic spine electrical dynamics. Dendritic spines, characterized by a small head (volume~0.01-0.1μm3) and narrow neck (diameter~0.1μm, length~1μm), are the primary site of excitatory synaptic input in the mammalian brain. Synaptic inputs made onto spines first integrate onto dendrites, and subsequently propagate towards the soma and axon initial segment, where they further integrate with other inputs to determine overall action potential output. Elucidating the electrical properties of spines is thus paramount for understanding the first steps along this signal processing chain. I will describe our work using quantum-dot labeled quartz nanopipettes (15-30 nm diameters) under two-photon visualization for targeted intracellular recordings from spines1 and small pre-synaptic terminals. I will show through detailed experiments that (i) spines receive large EPSPs (25-30mV), and (ii) estimated neck resistances are large enough to influence electrical isolation (mean ~420 M?), and filter synaptic input as it invades the dendrite. I will then briefly describe the theoretical implications of these properties2 and describe key advances in amplifier design that can enable previously unattainable experiments on spines4. I will then describe recent results from my lab using two-photon holography to stimulate spines in 3D to unravel dendritic spine co-operativity across dendrites. In the second part of this talk, I will switch gears and describe a new method in which I combine the flexible property of these nanopipettes with microprisms to enable simultaneous two-photon calcium imaging and targeted intracellular electrophysiology from dendrites in vivo during behavior3. Last, I will give a succinct overview of our recent work at Purdue, including two-photon compatible transparent nanoelectrode arrays for mapping dendritic activity from the surface of the awake-behaving brain. I will conclude by presenting a snapshot of key collaborative projects at Purdue that highlight the integration of nanoscience and neuroscience. 1 Jayant, K. et al.
