Temporary suspension of chemical use at Birck
by Jurss, Stephen E 02 Feb '22

02 Feb '22

Dear Birch Research Community, Due to the inclement weather we have reached a point where it would be difficult or impossible for an emergency vehicle to get to our building in a timely manner. This would include fire trucks in the event of a fire or hazardous gas leak, and an ambulance in the event of a personal accident within our building. Therefore, for the safety of our people and facilities, we are immediately restricting work within our cleanroom and labs to be non-hazardous work only. Any work requiring hazardous gases (toxic, flammable, or pyrophoric) is not allowed, and all fume-hood work is suspended. Non-hazardous processing, characterization, and analysis may continue. We realize this places a burden or research project flow but by these short-term restrictions we're keeping safety as our number one priority. We fully expect this restriction to be short-term, and all normal processing will be reinstated once our driveways and roadways are cleared. We will put out another announcement when this occurs. Thanks for your cooperation and for keeping Birck safe! Birck Safety Manager

Possible Winter Storm?
by Reger, Ronald K 31 Jan '22

31 Jan '22

Dear Birck Users, According to the weather forecast our area may get up to 10 inches of snow over the course of Wednesday and Thursday of this week, and it comes on the heels of rain on Tuesday. If it rains Tuesday and we have a sudden drop in temperature we may have significant snowfall on top of ice. Of course this is a weather forecast so it is subject to change significantly one way or the other, but we just wanted the Birck user community to be aware of this possibility. If this happens then there could be a few days delay in our ability to receive bulk gas supply, so anyone who needs long runs requiring Ar, N2, or O2 may want to consider planning for the worst-case scenario of a bulk gas delivery delay. Just for your consideration.

Micro-Bulk Argon Issue
by Reger, Ronald K 24 Jan '22

24 Jan '22

Dear Birck Researchers, For some reason (unknown at this time, we're investigating) our Argon usage rate doubled last Wednesday, January 19th. Our typical usage is about 0.2 inches per hour but starting on the 19th we increased to 0.4 inches per hour and it stayed at that rate. The end result was it ran our microbulk tank to zero, and since Linde doesn't refill on weekends we have been at zero for the last 24 hours. The engineering staff is shutting down all recharge equipment that uses Argon until we can refill the tank and purge the lines. If there are any faculty-owned instruments we recommend you not run until the Argon is restored and you do an appropriate purge. The Argon truck from Linde is on the way to Birck now to refill the tank. We're working with Linde to enhance our refill notifications that will include not only tank level but also usage rate. If anyone knows why the rate increased last Wednesday we would appreciate you sharing your insight with us. The Engineering Staff

FW: NEW LINK: John Williams/Boeing Virtual Seminar (Today, 9am)
by Shakouri, Ali 20 Jan '22

20 Jan '22

Sorry about the problem NEW LINK https://purdue-edu.zoom.us/j/92036338991 From: Shakouri, Ali Sent: Thursday, January 20, 2022 8:17 AM To: Shakouri, Ali <shakouri(a)purdue.edu<mailto:shakouri@purdue.edu>> Subject: John Williams/Boeing Virtual Seminar (Today, 9am) Dear All, We will have a special SMART seminar later today Thursday Jan. 20, 2022 (9-10:30am EST). Dr. John Williams, who is Technical Fellow at Boeing and Boeing’s representative at the Manufacturing USA Institute NextFlex, will give a virtual talk about their research in Flexible Hybrid Electronics (see below the abstract). This is a good opportunity to learn about industry interest in this area. Please note that this seminar won’t be recorded and it is only available for live discussion (~45min seminar + 45min questions and answers). Best regards, Ali Flexible Hybrid Electronics - Process Development and Applications John Williams, Ph.D., Technical Fellow Boeing Research and Technology, Huntsville, AL 35824 (256) 937–5904, john.d.williams14(a)boeing.com<mailto:john.d.williams14@boeing.com> Time: Thursday Jan 20, 2022 09:00-10:30 AM EST Boeing is actively engaged in the development of Flexible Hybrid Electronics. We began with single layer processes and have expanded rapidly prototype development of multilayer flexible printed circuit boards (Flex-PCBs) for size weight power and cost saving applications. Flex PCBs allow electronics to be wrapped onto cylindrical or bi-axial curved surfaces. Conventional Flex PCBs contain either one to four copper layers with limited electronic packaging. Most devices are bonded to rigid boards that contain complex packaged electronics. Boeing’s processes, however, apply copper clad or printed inks on polyimide substrates to build fully functional flex-PCBs up to eight conductive layers thick. Thus allowing antennas, sensors, communication links, and radars to be placed directly onto the surface of a vehicle. Similarly, power routing, and microcontrollers can conform to surfaces or interior cavities. This technology represents a transformative approach to packaging PCBs in aerospace applications. Our team has demonstrated this capability on RF boards with no less than 500 through vias, 100 buried vias, and 50 electronically packaged components. Complex boards can be turned in days without electroplating. Pyralux AP polyimide substrates from DuPont, Taconic, and 3M bonding adhesive achieves alignment errors of 2 mil or less over an 8 x 10 square inch area. Kapton substrates can also be used with additional alignment error. Patterning can be completed with either copper clad material or silver ink. Vias are filled using conductive inks. Electronic packaging is currently performed using anisotropic conductive epoxy, but industrially standard solder attach is also available for copper clad and plated devices. Cost models have been completed for printed silver devices, documenting the manufacturability from Manufacturing Readiness Levels (MRL) 4 to 6. We are currently examining pilot capability of different suppliers to manufacture devices at volumes needed for commercial activities. [clip_image001]John D. Williams received his PhD in Engineering Science from LSU in 2004 and became a NextFlex Fellow in 2019 and a Boeing Technical Fellow in 2022. John has 17 years of Principal Investigator experience in device fabrication and is currently the principal investigator on numerous NextFlex contracts focused on antenna arrays and multilayer printing on curved surfaces. John is currently developing Additive Electronics Technologies (AET) for use on Boeing platforms. From 2004 to 2014 he served as a Senior Member of the Technical Staff at Sandia National Laboratories, and as an Assistant Professor of Electrical, Optical and Material Engineering at the University of Alabama in Huntsville (UAH). He joined Boeing in 2014 to found the Boeing Research and Technology AET effort in Huntsville where his team performs novel research in microwave filters, antennas, and flexible hybrid electronic (FHE) sensors by maturing manufacturing capabilities, implementing modeling and simulation, and developing prototype demonstrators. John is the principal / co-principal investigator for 4 concurrent NextFlex MII Projects. He has led, or co-led, 7 other NextFlex projects, serves on the NextFlex Technical Council, and is an industry co-lead for the NextFlex Materials Technical Working Group. He also serves as an industrial committee member for the ManTech JDMTP Electronics Subpanel. In 2021 he served on the organizing committee for the IEEE International Flexible Electronics Technologies Conference (IFETC). John has published more than 30 peer reviewed articles, over 30 US patents, 17 international patents, 4 Boeing trade secrets, and dozens of pending patents. John’s Boeing related inventions on microwave filters, conformal antennas, hyperspectral metrology, and cryogenic cooling of MW class EMI filters are currently being developed for multiple BR&T efforts.

See below the link: https://nanohub.org/resources/35749 Rethinking the Nature and Nurture of Discovery Research Venky Narayanamurti Harvard University Abstract Research, particularly on the ?discovery? end of the R&D spectrum, is complex and easily misunderstood. Scientific advance doesn?t always precede, it often follows, engineering advance. Answering questions isn?t always the goal, finding questions often is. We don?t always seek to strengthen conventional wisdom, sometimes we seek to surprise it. What if we could rethink research so that its nurturing, through policy and management, harmonizes with its nature? ************ Workshop Hi All Members of BNC, I will be running CasaXPS workshop to teach how to analyze XPS data from January 18-20,2022 at 9.00am-1.00pm.
