BNC Faculty Seminar Series

April 22nd, 2021 | 12:00pm - 1:00pm | Alejandro Strachan, Professor of Materials Engineering, Deputy Director of the Purdue's Center for Predictive Materials and Devices (c-PRIMED) and of NSF's Network for Computational Nanotechnology

Title: First principles modeling of materials: novel electronics, ultra-low stiffness metals and open cloud computing in nanoHUB<https://www.purdue.edu/discoverypark/birck/events/index.php?view=3537>

Join Zoom: https://purdue-edu.zoom.us/j/91754078808

nanoHUB is excited to announce the first four workshops for the Spring 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

Date/Time: Friday, April 23, 2021 / 1:30 PM - 2:30 PM EDT

Title: Parsimonious Neural Networks Learn Interpretable Physical Laws
By: Saaketh Desai, Sandia National LabsRegister here (limited seats): https://nanohub.org/groups/ml/handsontraining
Abstract: Machine learning methods are widely used as surrogate models in the physical sciences, but less explored is the use of machine learning to discover interpretable laws from data. This tutorial introduces parsimonious neural networks (PNNs), a combination of neural networks and evolutionary optimization to find models that balance accuracy with parsimony. As an example, you will learn how to train a PNN to learn interpretable laws that predict the melting temperature of a material given fundamental properties such as elastic constants and volume. You will also learn how to interpret the discovered PNN models as physical laws, and understand how various PNN models, as well as traditional models such as the Lindemann melting law, trade parsimony and accuracy.

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.

Week of  May 3, 2021                     Week of  Oct 18, 2021
Week of  May 2, 2022                     Week of  Oct 17, 2022

Thank you for your cooperation and understanding during these important preventive maintenance shutdowns.  Please contact me if you need more detailed information.

Purdue asks campus community to participate in new COVID-19 vaccine verification program

All faculty, staff and students affiliated with the West Lafayette campus are encouraged to participate in a new verification program once they've been fully vaccinated for COVID-19 to assist Protect Purdue efforts in managing the health and safety of the campus community.
Through a brief Qualtrics survey<https://purdue.ca1.qualtrics.com/jfe/form/SV_e3EkbNvNGWk5Jiu>, those who have fully completed their COVID-19 vaccination - two shots of Moderna/Pfizer or the single dosage of Johnson & Johnson - can upload an image of their vaccine verification card and communicate any related details to the Protect Purdue Health Center.
