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]

Reminder: BNC Faculty Seminar TODAY @ 12:00noon. [cid:image004.jpg@01D685C0.EB336F80] The BNC Faculty Seminar Series is designed to provide faculty a platform to present an overview of their research and the opportunity for collaborative discussion with other BNC faculty and researchers across six colleges and 15 academic units. 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 April 22nd, 2021 | 12:00pm Join Zoom: https://purdue-edu.zoom.us/j/91754078808 Title: First principles modeling of materials: novel electronics, ultra-low stiffness metals and open cloud computing in nanoHUB Abstract: First principles-based modeling and data science are playing an increasingly important role in the design and understanding of new materials and devices for a range of applications. I will discuss recent progress in our group on the application of these tools in materials of technological interest and efforts on cyber-infrastructure aimed at making these tools universally accessible and useful. I will discuss recent applications of molecular dynamics (MD) simulations to materials science problems, from revealing the molecular mechanisms behind the formation of fibrils in polymers to the operation of nanoscale resistance switching devices of for nanoelectronics. The latter are enabled by a new model to describe the effect of an external electrochemical potential in MD simulations and, thus, electrochemical reactions. The simulations predict the ultrafast switching observed experimentally and provide new insight into the atomistic mechanisms behind the development and dissolution of stable conducting filaments both in electrochemical metallic cells and valence change devices. I will also discuss the use of data science tools in the field of materials science. Specifically, I will discuss the combination of multi-fidelity experiments and physics-based modeling with machine learning tools with the ultimate goal of designing refractory complex concentrated alloys with unprecedented combination of high-temperature strength and oxidation resistance. Specifically, I will discuss the integration of information from disparate sources and with different uncertainties into predictive models and the use of surrogate models to reduce the number of full-scale experiments required. Finally, I will also describe recent developments in nanoHUB, an open cyberinfrastructure for cloud scientific computing that seeks to maximize the impact of simulation tools and data. Tool developers can make their products easily available to end users and these educators, students, and researchers can access apps and tools directly from their web-browsers or tablets without downloading or installing any software. With a short tutorial, I will exemplify how nanoHUB is being used in education and research and how its cyberinfrastructure can enhance the impact of simulations in science and engineering.

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.
