Dilley, Ph.D. Research Scientist Birck Nanotechnology Center , Rm 1010 1205 West State St. West Lafayette, IN 47907-2057 765-496-6080 Announcement: [cid:image003.png@01D8C389.DF2C06D0] Chemical Use at Birck Dear All – We recently had an incident where H2O2 was stored on the BOE shelf in a chemical storage cabinet in the cleanroom. The next user retrieved the H2O2 thinking it was BOE, and got a much different outcome from his etch. So two reminders to our research community: A. Please store chemicals in the proper, labeled locations in our chemical storage cabinets. B. Double-check the labels on chemical bottles prior to using them in your process. Thanks, Ron Dear Birck Research Community, Recently we had an air handling situation whereby the heat and humidity in one of our lab wings was elevated due to an air handler being off-line for repair. With the high heat and humidity in the lab wing it was necessary to open doors to the affected labs to try to promote some level of cooling from the hallway. The air handler issue was fixed within a couple of days and the A/C returned to normal in the labs. As a reminder, propping doors open is strictly against our policy under all normal conditions. Additionally, entering a lab without swiping in with your own card is also strictly against our policies. We rely on our card-swipe and equipment-use income to support and fund our operation. Anyone who enters a lab without swiping their card, or who enters a lab using someone else’s card, or who knocks on a lab door and is admitted by someone already in the lab is falsifying use of the lab. This will lead to disciplinary action up to and including dismissal from the university. Please use your cards responsibly in our research facility. Birck Management Buffered Oxide Etch Concentration Change We were notified by our BOE supplier, VWR, that they are discontinuing their 6:1 solution but will continue stocking & selling the 5:1 solution. We have two cases left of the 6:1 but will start ordering the 5:1 for future use at Birck. Please note the etch rate change per this comparison table: [cid:image004.png@01D8B3BF.33698B30] Safety: Dear Birck Users, Birck and Bindley are moving to an ANSI-compliant safety glasses policy in our labs. What this means is that prescription glasses that aren’t ANSI Z87.1 compliant will no longer be allowed for work in Birck labs or the cleanroom. Either ANSI-compliant safety glasses currently supplied to labs or ANSI-compliant prescription glasses are required to be worn to enter the laboratory. Verbal warnings will be issued to non-compliant users until September 1, 2022 after which more formal action will be taken. Stephen Jurss Birck Safety Manager Dear Birck Users: In an effort to comply with university policy and OSHA regulation Birck is making access to Safety Data Sheets available via QR codes located on the laboratory hoods. Please be aware we are removing hardcopy binders from various locations throughout the facility. Please note: SDS’s will still be required with all chemical orders.

The multimode correlation observed can be used to develop better imaging systems, potentially beyond classical boundaries. Best, Mahdi Hosseini, PhD Assistant Professor, Elmore Family School of Electrical and Computer Engineering, Assistant Professor, Physics and Astronomy (by Courtesy), Birck Nanotechnology Center, BRK 2274 Research Positions: Rahimi Lab Birck Nanotechnology Center Rahimi Lab<https://www.rahimilab.org/> has three research positions for graduate/undergraduate students over Fall 2022. One research area is wireless sensor design and implementation for biomedical and healthcare applications. The second research area is wireless soil sensors for precision agriculture applications. These two positions are open for students in CS/ECE/BME with a background in RF characterization, PCB design, Arduino/nRF programming, and/or Antenna design and measurements. The third research area is laser-assisted manufacturing of wearable sensors. This position is open for students with a background in CS/ECE/MSE with experience or interest in laser-assisted manufacturing processes. The students will receive training and assistance on software, such as Altium and Arduino, and characterization equipment, such as a vector network analyzer. With guidance, the students will also perform antenna measurements in an anechoic chamber facility and in agricultural fields. For manufacturing, students will get trained on laser engraving tools. [cid:image001.png@01D8C378.BE0EEA50] Motivated students with prior experience in these areas are preferred. If interested, please email Prof. Rahim Rahimi (rrahimi@purdue.edu<mailto:rrahimi@purdue.edu>) with a brief explanation of your background and prior experience and an attached resume.
