Seminars /Workshops / Events / Announcement [cid:image014.png@01D8BEC2.BAD31C40] Announcement: 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.
