Seminars /Workshops / Events / Announcement Upcoming Seminar: [cid:image007.png@01D8EC88.F7138A70] [cid:image019.png@01D8ED11.9E7B0940] [cid:image011.png@01D8EC89.FB372700] [cid:image021.png@01D8ED11.9E7B0940] Announcement: Attention to all sputtering users: In early June of this year, we removed all access to the sputtering tools in the cleanroom due to lengthy lead times in obtaining replacement parts, as a precaution to help maintain the up-time of the tools. As we have received the appropriate assortment of parts to perform maintenance on the tools as issues arise, we have decided to start opening up the tools to users once again. Starting Monday, October 31st, the Metal/Dielectric sputter tool only will be once again available for training and use. Since it’s been almost 5 months since anyone has used the tool, we have changed trained users’ access level to “Preliminary.” When you want to use the tool, make a reservation during business hours (8AM to 5PM, Monday through Friday), and we will coordinate such that your first deposition will be supervised by a staff member, to act as a refresher training after not using the tool for so long. Then, once it’s deemed appropriate to do so, users’ access will be restored to the normal level. Please contact Dave Lubelski and Dan Witter for questions and coordinating training and usage, and please check the tool’s wiki page for updated material availability and compatibility. If the desired material isn’t installed, please let us know ahead of time so we can appropriately prepare the system. Dan Witter 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.

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.

CasaXPS workshop announcement
by Abrol, Sangeeta Saddul 28 Oct '22

28 Oct '22

Sent on behalf of Dmitry Zemlyanov Dear Colleagues, I just would like to announce that a CasaXPS workshop "Introduction to CasaXPS: What we should know about XPS data analysis with CasaXPS" has been scheduled on November 14-16, 2022 at 4.00 pm - 7.00 pm. Every research group using or planning to use Surface Analysis characterization tools should have at least one trained student. Course Description: XPS is widely used to determine the chemical composition of a surface (element concentrations, chemical states, lateral and depth distributions, etc.) Nowadays XPS has become a standard technique for the characterization of solid surface. However, XPS data require thorough analysis, and dedicated software is used for data analysis. Purdue University has a site license for CasaXPS allowing complete analysis of XPS data. The course aims to teach (1) what analysis should be applied to raw XPS data and (2) how this can be done using CasaXPS. Qualitative and quantitative analysis of XPS data using CasaXPS will be discussed in detail as well. This is practical workshop, and an attendee is strongly recommended to brings their own laptop (Windows). The instruction how to install CasaXPS will be submitted before the workshop beginning. Registration is at https://forms.gle/t1Rwxf1CeQG2etVn6 Cost is $250 (can be used as a credit for XPS analysis). Please let me know if you have any questions. Thank you! *************************************** Thank you!
