Season's Greetings

24 Nov '21

Dear All, As the year is coming to close, we reflect on unprecedented events that have impacted all of our lives. This is a difficult situation with self isolation and physical distancing, especially for many of our international students and researchers who are thousands of miles away from their families. There are some who have been personally impacted with the loss of family members and millions who are in economic hardship. During these difficult times, we appreciate unique gifts and contributions from each member of our community. We are fortunate to have dedicated students, staff and faculty who went out of their ways and regular responsibilities to help each other. We managed to keep Birck operational for critical research between April and June. Our dedicated staff and faculty developed standard operating procedures for all labs and cleanroom that are shared by more than 500 users across campus. Thanks to everybody who has been careful and extra vigilant, we had a smooth operation during the Fall semester. We would like to thank everybody's great contributions and hope you will have safe and healthy end of the year holidays and best wishes for the New Year 2021. Sincerely, Ali, Zhihong and Sunil [cid:image002.png@01D6D3A2.91AE72E0]

[cid:image006.jpg@01D685C3.FA345960] Responding to COVID-19: Research Operations at Birck https://www.purdue.edu/discoverypark/birck/for-birck-users/covid/index.php Seminars /Workshops / Events nanoHUB is excited to announce the first two workshops in the Summer 2021 session of our Hands-on Data Science and Machine Learning Training Series. Series information. Our series is aimed at active researchers and educators and designed to introduce practical skills with online, hands-on activities participnts will be able to incorporate in their work. Hands-on activities will use nanoHUB cloud computing resources, no need to download or install any software. All you need is an internet connection and a browser. After the training sessions, you will be able to continue using nanoHUB for research or education. Registration links and material for prior workshops can be found at the workshop webpage: https://nanohub.org/groups/ml/handsontraining Register soon as seats are limited. Title: A Hands-on Introduction to Physics-Informed Neural Networks Date: May 26th 2021, 1:30 PM - 2:30 PM EST Speaker: Ilias Bilionis, Purdue University Register here (limited seats): https://nanohub.org/groups/ml/handsontraining Abstract: Can you make a neural network satisfy a physical law? There are two main types of these laws: symmetries and ordinary/partial differential equations. I will focus on differential equations in this short presentation. The simplest way to bake information about a differential equation with neural networks is to create a regularization term for the loss function used in training. I will explain the mathematics of this idea. I will also talk about applying physics-informed neural networks to a plethora of applications spanning the range from solving differential equations for all possible parameters in one sweep (e.g., solve for all boundary conditions) to calibrating differential equations using data to design optimization. Then, we will work on a hands-on activity that shows you to implement the ideas in PyTorch. I am assuming some familiarity with how conventional neural networks are trained (stochastic gradient descent). Also, you need to know the basics of PyTorch to follow along. Going over this tutorial should be sufficient: https://pytorch.org/tutorials/beginner/pytorch_with_examples.html. Title: Batch Reification Fusion Optimization (BAREFOOT) Framework Date: June 2nd 2021, 1:30 PM - 2:30 PM EST Speaker: Richard Couperthwaite, Texas A&M University Register here (limited seats): https://nanohub.org/groups/ml/handsontraining Abstract: This tutorial will present the fundamentals of multi-fidelity fusion as well as Sequential and Batch Bayesian Optimization as possible optimization approaches that can be integrated with high accuracy computational models or experimental procedures to speed up the optimization or design of materials. The tutorial will also provide an overview of the BAREFOOT framework that combines these two approaches together to further improve the rate of the optimization. All these approaches are compared using the optimization of the workability of a dual-phase steel microstructure.

Training queues have been increasing lately due to new users coming to Birck and current researchers sometimes expanding their project scope. We're anticipating an influx of additional new users over the Summer and into the Fall semester so we are considering a number of actions to help us become more efficient in providing user trainings. Among these ideas are..... 1. Increasing the number of users being trained from 1 to 2, as appropriate. This is being considered on a case-by-case basis taking into account the requirement to maintain a COVID-safe training experience. 2. Supplementing our SOPs with video overviews as we can get them developed. 3. Providing more pre-work online prior to the in-person training. 4. Coordinating training timing to better match when the users need to first use the tools. Thanks for your support of our efforts, and we would be happy to hear other ideas you have to make our training process more efficient.

In order to continue using equipment at Birck we opened all the interlocks and encouraged users to pre-reserve equipment for the weekend which would allow us to process manual billings per the reservations since iLabs was totally offline. It turns out that the iLabs outage was much shorter than anticipated so we were back online with iLabs and interlocks at approximately 11:00 am on Saturday. Thanks for your patience and we thank the iLabs organization for dealing with their planned outage in the most expedient way.

ILabs Outage This Weekend
by Reger, Ronald K 06 May '21

06 May '21

Dear Birck Research Community, Agilent Technologies, the supplier of our iLabs reservation and billing software, has notified us of a planned iLabs outage beginning on Friday, May 7 at 9:00 pm and lasting into the weekend. Originally they had planned for a 12-hour outage but recent indications are that it could take longer, maybe up to 48 hours. During this time iLabs will be unusable and unavailable. We are faced with two scenarios for dealing with this: 1. Keep all instrument interlocks activated and then no tools will be available until the outage is concluded, or 2. Open all the interlocks, strongly encourage reservations to be made in advance of the 9:00 pm May 7th shut down, and bill fur use according to the pre-arranged reservations. Also, if walk-up use is done during the outage the user should email the tool owner to notify them about the unreserved use so that proper billings can occur for these cases. We choose to follow Option B, asking for everyone who needs tools this weekend to reserve them in iLabs before 9:00 pm on May 7th if at all possible. We feel this is the best option considering our facility has been down this week for routine preventive maintenance activities, and users are waiting to get access to the tools again. Please follow our guidance for Option B, using pre-reservations and walk-ups while the iLabs system is offline. As soon as they’re finished with their outage we will reactivate the interlocks back to normal operation. Thanks for your cooperation, Ron

When research work resumes please keep the hoods clean, tidy, and remember to remove all unused glassware and to label all your experiments. [cid:image007.png@01D73AB6.EEECE380] Here is what BNC wiki page<https://wiki.itap.purdue.edu/display/BNCWiki/Lab+Policies+and+Best+Practice…> tells us. If the bottles in the hood are empty, refill them from a supply bottle. It is in the cabinet below the hood. (if not it can be taken from the storage cabinet) Label the chemicals, samples, or glassware that left unattended, with "researcher name_Major constituents of material_Date of Disposal/ return" * Clean the workspace (fume hood, lab bench or equipment) after use, with * any chemicals on the hood surface wiped up or rinsed, * used cleanroom wipes removed * all aluminum foil removed * any glassware containing chemicals labeled and pushed to the back of the hood * any empty glassware removed * and chemical supply bottles returned to the proper storage cabinet ("Corrosives" for concentrated acids/bases or "Flammable" for solvents/developers). Together, we make the clean room clean and nano bigger. Birck Nanotechnology Center PM Closure Notice The Birck Nanotechnology Center will be undergoing a semi-annual preventive maintenance and service shutdown May 3 through May 7, 2021. Air handling systems, exhaust systems, toxic gas delivery, and monitoring systems will be down beginning at 7 a.m. Monday, May 3 through 4 p.m. Friday, May 7. The BNC staff will be performing appropriate preventive maintenance on the process equipment at this time as well. All CLEANROOM research work will be suspended until the maintenance activities are completed and all systems are returned to normal. Only authorized personnel will be allowed to enter the cleanroom during this time period. In addition, the laboratory areas will also be affected by this systems maintenance. As such, all LABORATORY activities that involve exhausted hoods, vacuum systems, and/or toxic gas systems will be down beginning 7 a.m. Monday, May 3 through 4 p.m. Friday, May 7. However, work that involves taking standard electrical measurements may be carried out in the LABS provided that fluctuating air temperature and humidity do not affect the readings. No chemical work will be allowed during this period. It is anticipated that the building and process tool maintenance will be completed by the end of the day on Friday, May 7. Please check iLabs for equipment status and availability. For long term research planning please refer the following future dates for our future preventive maintenance shutdowns.
