[cid:image001.jpg@01D4EDE9.DE5D5B10] Seminars /Workshops / Events SMART Films Workshop<https://www.purdue.edu/discoverypark/birck/events/index.php?view=2508> Thursday, December 5th, 2019 8:30am - 2:00pm, MRGN 121 BNC Seminar: Ying Diao<https://www.purdue.edu/discoverypark/birck/events/index.php?view=2505> December 12th @ 1:30pm in BRK 1001 Directing Assembly of Organic Electronics Inspired by Living Systems Birck Events<https://www.purdue.edu/discoverypark/birck/events/index.php> and Birck News<https://www.purdue.edu/discoverypark/birck/news/index.php> 2019 - 2020 Holiday Shutdown Notice Dear Birck Users and Research Community, With the extended break this year between the Christmas and New Year's holidays the university will be closed for 12 days in a row, beginning Friday, at 3:30PM December 20th and concluding Thursday morning, January 2nd. Please note the time and complete any processes requiring hazardous gases before 3:30 pm Friday. This represents a challenge for us to maintain some limited research capability while the university is officially closed with no staff members present. Therefore the Birck Nanotechnology Center will implement the following policy for the duration of this time period: 1. No toxic, flammable, or hazardous gases will be available. This includes hydrogen, methane, silane, dichlorosilane, ammonia, H2S, ALD sources, BCl3, nitric oxide, chlorine, & KrF. These gases will be shut off at the source and no processes using these gases will be allowed. 2. Nitrogen, argon, helium, forming gas, SF6, CF4, C4F8, and oxygen will continue to be available. 3. Cleanroom and laboratory operations will still be available as long as they don't use any hazardous gases. 4. Fume hoods will be open for use but please make sure someone else is in the same lab area or cleanroom bay if you're going to work alone in the hood. No HF, BOE, or TMAH work is to be performed during this time. The RCA Hood will be unavailable for use. 5. Loading dock will be closed with no shipping and receiving coverage and no deliveries accepted. 6. There will be no custodial service during holiday time so trash and bathroom conditions will not be maintained. 7. Stocked materials should be especially conserved by all users as no deliveries to the university will occur during this period, and stocking of on-hand materials may occur on a very limited basis. 8. Cleanroom users should continue to re-use their cleanroom gowns and other garments as much as possible since the shipping of used garments to our laundering supplier will be unavailable during this time. 9. Staff will not be working normal hours but some may intermittently stop in for brief walk-throughs and checks. Thank you for your support of this extended period of time for staff, faculty, and students to enjoy time off with family and to refresh. Birck Nanotechnology Center Leadership Microfluidics course announcement - Spring 2020 (see attached announcement for more details) Microscopic flows are everywhere these days. In fact they've always been all around us but we haven't noticed. Despite their prevalence in science and engineering fields, they are not well understood-in large part because the fluid mechanics intuition developed in the study of macroscale flows frequently does not apply to microscopic flows. This class will prepare engineers and scientists to address problems they will encounter when studying the behavior of fluid flows in microscopic domains. The course will concentrate on behaviors not typically important at large length scales that become very important at small length scales, such as Van der Waals forces, surface tension, and electrostatic forces. The course will take a largely analytical approach to studying these flow phenomena although some computational modeling will also performed and several lab demos and visits are planned. Previous experience with graduate level fluid mechanics (i.e. Navier-Stokes solutions) or continuum mechanics will be helpful. Some computational analysis of model problems may be performed using commercial software (ANSYS/Fluent/COMSOL or related). Instructor: Steve Wereley, Mechanical Engineering (wereley(a)purdue.edu<mailto:wereley@purdue.edu>) Course Objectives: 1. To learn how fluids behave in microscopic domains that are still large enough for continuum flow approximations to hold. 2. To learn where the continuum assumptions are no longer valid. 3. To learn how to treat sub-continuum fluid flows. Prerequisites by Topic: The student should be of graduate standing. The student should have had some previous experience with graduate level fluid mechanics, in particular solving the Navier-Stokes equations. Computer Usage: The students may need to use ANSYS, Matlab, Fluent, COMSOL or a comparable package, to perform some of the computations necessary for the course. Assessment Methods: Grades will be based on homework assignments, two projects, and a final exam. The relative weight of these components is 25%, 50%, and 25%, respectively. Jischke Drive Repairs - April - August, 2020 Project Overview South Martin Jischke Drive from State Street to Harrison Street will be repaired next year, and utility work in the area will also occur. This section of South Martin Jischke Drive will be closed in phases while work is ongoing, and some adjacent sidewalk and ramps will be unavailable. We will be constructing a pedestrian "bump out" on the east and west side where the cross walks are located. The bump out will improve pedestrian safety. We will also be adding a short section of bike lane that will connect the existing bike lane that dead ends at the south end of Burton Morgan Dr. with bike lane at the corner of State and Jischke. Project Schedule While we are still in the design phase and the schedule is not yet final, we anticipate sidewalk repairs and utility work will begin in April 2020 with road closures beginning in May. Road work will be completed in two phases after spring commencement and before Boiler Gold Rush in August. The first phase will close northern half of the road from State Street to just south of the TERY parking lot entrance. This section will be reopened after repairs are complete, and then the remaining portion of South Jischke Drive from south of the TERY parking lot to Harrison Street will close for repairs. Access to TERY will be maintained throughout the project. Parking along Jischke will not be available during construction. Our Request for Your Participation To streamline feedback, occupants should communicate needs and concerns for April-August 2020 with their assigned building deputy. Topics may include, but are not limited to the following: * Vehicular / pedestrian access from South Jischke Drive * Parking - temporary accommodations during construction * Operational needs such as deliveries (provide truck size and frequency) * Visitors or summer conferences - access and communications that are needed for visitors * Trash / recycle pick up, including current locations and potential summer options Please communicate any needs and concerns with the appropriate assigned building deputy, see below. * Steve Rudolph - MRGN, MANN sgrudolph(a)purdue.edu<mailto:sgrudolph@purdue.edu> * Phil Austin - BIND pjaustin(a)purdue.edu<mailto:pjaustin@purdue.edu> * Mary Jo Totten - BRK tottenm(a)purdue.edu<mailto:tottenm@purdue.edu> * Eric Ridgley - DLR ewridgley(a)purdue.edu<mailto:ewridgley@purdue.edu> * Stu Michael - DRUG michaesd(a)purdue.edu<mailto:michaesd@purdue.edu> Follow us on Facebook and Twitter [Facebook icon]<https://www.facebook.com/nano.purdue.edu/> [Twitter icon] <https://twitter.com/BNCPurdue> ***If you would like to share a Thank You/Kudos for a Birck staff, student or faculty who went above and beyond in the weekly news and atrium TV's please send to jjturner(a)purdue.edu<mailto:jjturner@purdue.edu> *** ***If you have any news items (published papers, research news, awards, honors) please send to jjturner(a)purdue.edu<mailto:jjturner@purdue.edu> so they may be included on Birck's website, Facebook and Twitter pages*** Jaime Turner Administrative Assistant to the Director Birck Nanotechnology Center | Room 1027 | W.

Birck Argon Update
by Reger, Ronald K 25 Nov '19

25 Nov '19

Dear Birck Researchers, The Praxair people, along with our process piping contractor Cryogenics-LLC, have restored our house Argon to its normal delivery pressure, and we now have a full tank of liquid Argon as well. The root cause was theorized to be an exceptionally high use somewhere in the building that not only quickly depleted the tank but also lowered the delivery pressure. We're asking anyone who has used excessive Argon recently to let us know. Going forward please let the engineering staff know if you intend to use a high Argon flow for some process. We are also working with Praxair to track when deliveries have been made over time and to see if delivery frequency has increased recently. So, Argon pressure and delivery has been restored back to normal levels. Thank you for your patience.

Argon Use Question
by Reger, Ronald K 25 Nov '19

25 Nov '19

Dear Birck Researchers, In addition to the pressure builder issue on the Argon tank there seems to maybe be a higher usage of Ar gas in Birck. If someone has increased Argon usage please let me know ASAP ..... where and by how much.

Birck Argon Update
by Reger, Ronald K 25 Nov '19

25 Nov '19

Dear Birck researchers, We began to have an issue with our micro-bulk Argon tank last Friday afternoon. A Praxair technician determined the pressure builder was faulty and Praxair service people are working to get it repaired. They filled the tank last Friday afternoon but the delivery pressure was lower than normal, hence the need for repair of the pressure builder. As of today we have "0" pressure in the Argon line and service has been called and is on the way. We will keep you updated as work progresses and as we get additional information.

REMINDER: Arun Majumdar Seminar TODAY at 10am PGSC
by Turner, Jaime J 21 Nov '19

REMINDER: Arun Majumdar Seminar TODAY @ 10am in PGSC --------------------------------------------------------------------------- Thermoelectric Energy Conversion: Science and Engineering Challenges and Opportunities Arun Majumdar Stanford University Thursday, November 21, 2019 10:00 am • Purdue Graduate Student Center (PGSC) Followed by a fireside chat with Ali Shakouri Abstract: The last 20 years have witnessed intense research focus on the science and engineering of solid-state thermoelectric materials, with the goal of achieving high ZT (~ 2-3) over a large temperature range and thus enabling commercial technology for waste heat recovery and cooling. While the scientific research has to led many fundamental insights about how to engineer the behavior of electrons and phonons, the promise of high ZT and widely-used commercial technology remains largely unfulfilled.For waste heat recovery, this is partly because the performance targets have been raised due to competition from increasingly lower cost of solar and wind electricity. However, with the phasing out of today’s refrigerants due to the Kigali amendment of the Montreal Protocol, cooling offers an enormous opportunity if high ZT materials can be developed for room temperature operation, and system-level costs can be reduced and performance increased. The increase of ZT at room temperature requires new mechanisms and science to engineer the electronic and phononic structure and transport. This talk will provide a viewpoint of these new scientific opportunities and challenges in the context of practical performance and cost metrics. It will also offer new approaches to manipulate entropy change in liquid media for the purpose of energy conversion. Bio: Dr. Arun Majumdar is the Jay Precourt Provostial Chair Professor at Stanford, and a faculty member in Mechanical Engineering and Materials Science and Engineering. He is co-director of the Precourt Institute for Energy, which integrates and coordinates research and education activities across all seven Schools and the Hoover Institution. Dr. Majumdar's current research focuses on electrochemical and thermochemical redox reactions that are fundamental to a sustainable energy future, multidimensional nanoscale imaging and microscopy, and a new effort to re-engineer the electricity grid using data science, including deep learning techniques. He was the founding director of ARPA-E before which he was the Almy & Agnes Maynard Chair Professor of Mechanical Engineering and Materials Science & Engineering at UC–Berkeley. Dr. Majumdar is a member of the National Academy of Engineering and the American Academy of Arts and Sciences.
