Dear All, I hope you are enjoying end of the year holidays. I would like to thank sincerely everybody who helped to organize the Birck holiday party last week. It was great to see many students, staff and faculty in person. I appreciate very much kind words of Zhihong, Vlad, Sasha and everybody else who participated. My holiday messages typically include a photo of Birck with beautiful snow surrounding the center (this year’s snow is yet to come!). Venky Narayanamurti’s seminar couple of weeks ago made reference to an outstanding speech by Ralph Bown who said in 1952: “vitality of a research organization is only a composite of the spirit of the people in it. It has little to do with buildings or equipment, although indeed these things are important mechanical factors in its existence.” Instead of a photo, I have included below a link to Bown’s article to acknowledge the outstanding contribution of everybody who has helped create Birck's vibrant research atmosphere. As we are dealing with challenges due to COVID and some of the unfortunate polarizations in the country, it is good to be reminded about the importance of human relations and imagination to overcome differences and in shaping our future. As Whitehead said almost century ago, the “justification for a university is to preserve the connection between knowledge and the zest of life, by uniting the young and the old in the imaginative consideration of learning.” Below, I have included a link to Purdue 2050, Conference of the Future, where several guests and colleagues shared their imagination about the future we want to create for our children. If you have couple of minutes, here is a short video summary: https://youtu.be/_Jogf4PVfgw Thanks to everybody for providing an amazing environment to work, to grow and for all of the friendship and advice. This has been a real privilege to work with all of you. Best regards, Ali PS.

22 Dec '21

Dear All Birck Nanotechnology Center Researchers, As of 3:30 pm today, Wednesday December 22, the Birck center has been put into winter recess mode. Hazardous gases have been turned off, and the other winter recess procedures/protocols are now in place. The center will remain in this state until Monday morning, January 3 when the university reopens. For details about the Birck recess mode please see the below announcement that we have been publishing every week for several weeks. Have a happy holiday season and we will see you again in the new year! Previous announcement: On behalf of the Birck Leadership Team....... Dear Birck Research Community, The Purdue winter recess occurs December 23rd through January 2. The university is officially closed during this time and reopens on Monday January 3. As we have done in past years, the Birck Nanotechnology Center will remain available for research but will be unstaffed and hazardous gasses will be unavailable. As always if you plan to do any work over the recess please follow all applicable Protect Purdue protocols. Following is a description of the Birck center during this period of university closure: 1. All labs and cleanroom will be open. 2. All hazardous gases will be unavailable. 3. HF, BOE, and TMAH chemical processing will be allowed as long as a buddy is present. 4. Precursors for ALD systems will be available. 5. No shipping or receiving is being done at any building on campus. 6. The custodians will not be working so restrooms will not be maintained, and sanitation of touch surfaces will not be done. * We encourage users to keep the facility clean and be extra vigilant about the hygiene and COVID risks. 7. A few engineering and building staff may walk through occasionally for major issues but availability will be very limited and could be impacted due to COVID restrictions. * Faculty and senior researchers are encouraged to be more proactive (e.g. occasional walk throughs checking the labs where there is ongoing research). Email Birck management if you notice anything. Since there will be limited staff support during this winter recess the research groups are strongly encouraged to accomplish as much processing as possible before gases are turned off on Dec. 22. See the following for more detailed information (this will be up on the BNC Wiki): 2021-12-23 to 2022-01-03: Reduced Holiday Operations Due to Purdue's Winter Recess hazardous gases will be unavailable from 3:30 PM Wednesday, December 22 until 8:00 AM on Monday, Jan 3rd.

[cid:image006.png@01D7401C.A3F567B0] Seminars /Workshops / Events/Announcement Birck Nanotechnology Center Distinguished Seminar "Rethinking the Nature and Nurture of Discovery Research" Monday December 13, 2021, 3-4pm, Burton Morgan 121 with extended informal Q&A and discussion for 30m immediately following. Speaker: Venky Narayanamurti (Harvard University) Abstract: Research, particularly on the "discovery" end of the R&D spectrum, is complex and easily misunderstood. Scientific advance doesn't always precede, it often follows, engineering advance. Answering questions isn't always the goal, finding questions often is. We don't always seek to strengthen conventional wisdom, sometimes we seek to surprise it. What if we could rethink research so that its nurturing, through policy and management, harmonizes with its nature? Join us for a conversation between Venky Narayanamurti and Ali Shakouri on Venky's new book<https://www.hup.harvard.edu/catalog.php?isbn=9780674251854> with Jeff Tsao, "The Genesis of Technoscientific Revolutions" (Harvard University Press, Nov 2021) addressing this question. Speaker Bio: Venkatesh Narayanamurti is Benjamin Peirce Professor of Technology and Public Policy, Engineering and Applied Sciences, and Physics Emeritus at Harvard University. He was formerly: Director of the Science, Technology and Public Policy Program at the Harvard Kennedy School (2009-2015); John L. Armstrong Professor and Founding Dean of the Harvard School of Engineering and Applied Sciences, and Professor of Physics and Dean of Physical Sciences at Harvard (1998-2009); Dean of the UCSB College of Engineering (1992-1998); VP of Research at Sandia National Laboratories (1987-1992); and researcher then Director of the Solid State Electronics Research Laboratory at Bell Labs (1968-1987). He is a Fellow of the American Academy of Arts and Sciences and an elected member of the U.S National Academy of Engineering, of the Royal Swedish Academy of Engineering Sciences and of the World Academy of Sciences. He is also co-author, with Professor Tolu Odumosu (James Madison University), of "Cycles of Invention and Discovery" (Harvard University Press, 2016). Workshop Midwest Quantum Collaboratory Workshop - December 16 Dear all, Purdue has partnered with the University of Michigan and Michigan State University to launch the Midwest Quantum Collaboratory.

Twitter: @PurdueQuantum<https://twitter.com/PurdueQuantum>, LinkedIn<https://www.linkedin.com/company/pqsei/>, Facebook<https://www.facebook.com/QuantumPurdue> Join our upcoming hands-on workshop on thermodynamics and kinetic calculations in materials science using Thermo-Calc. Motivated by integrated materials engineering (ICME) and the materials genome (MGI), the hands-on workshop will exemplify the use of Thermo-Calc in the classroom and research. The target audience is instructors, researchers and students. The academic version of Thermo-Calc is now freely available in nanoHUB through a collaboration between Thermo-Calc and nanoHUB. You can access this software by joining the Thermo-Calc group in nanoHUB: https://nanohub.org/groups/tcacademic. Title: Integrated Computational Materials Engineering in the Classroom: Teaching Fundamental Thermodynamics and Kinetics Through an Industry-Focused Lens using Free Online Simulations. Presenter: Adam Hope, PhD, Thermo-Calc Software Inc. Date/Time: Wednesday, December 15, 2021 from 1:00 PM - 2:00 PM EST Register here: https://purdue.webex.com/purdue/onstage/g.php?MTID=e1f44a88da6016a3b691b737… Abstract: Both the National Academies report on Integrated Computational Materials Engineering and the Materials Genome Initiative have highlighted the importance of linking materials, chemistry, and processing to microstructure in order to predict and engineer material properties and performance. This is especially important in the context of Industry 4.0. However, some of the challenges in implementing such an approach are: * Linking models across length scales * The lack of materials property data as a function of chemical composition and temperature * The lack of familiarity and awareness of engineers on design teams as to the different types of modeling tools which are outside their background, especially those which transcend the more traditional gaps between materials science and mechanical engineering. Modeling chemistry-process-structure relationships requires a solid foundation of thermodynamics, phase equilibria and kinetics. The CALPHAD (Calculation of Phase Diagrams) method fits this need. CALPHAD is a phenomenological approach for calculating/predicting thermodynamic, kinetic, and other properties of multicomponent materials systems. It is based on describing the properties of the fundamental building blocks of materials, starting from pure elements and binary and ternary systems. With extrapolation from the binary and ternary systems, CALPHAD predicts the properties of higher order alloys. Over the last decades, the CALPHAD method has successfully been used for development of numerous real engineering materials. CALPHAD tools are not only a critical component of any ICME framework, but they also create an opportunity to assist in teaching thermodynamics - from understanding the influence of chemistry on Gibbs free energy to constructing simple binary phase diagrams. This fundamental approach can then be extended to multicomponent systems to study real engineering materials. This presentation will demonstrate ways that Thermo-Calc can be used in the classroom, as a teaching tool, and in industry, as a research and problem solving tool for any ICME framework. Bio: Adam received his PhD in Welding Engineering at The Ohio State University. His work was focused on integrating computational and experimental techniques to predict susceptibility to weld cracking, and to develop new weld metal compositions for nuclear power applications. Adam currently works at Thermo-Calc Software providing training and applications support to users. I hope that you can join us in this workshop!

Dear Birck Research Community, The Purdue winter recess occurs December 23rd through January 2. The university is officially closed during this time and reopens on Monday January 3. As we have done in past years, the Birck Nanotechnology Center will remain available for research but will be unstaffed and hazardous gasses will be unavailable. As always if you plan to do any work over the recess please follow all applicable Protect Purdue protocols. Following is a description of the Birck center during this period of university closure: 1. All labs and cleanroom will be open. 2. All hazardous gases will be unavailable. 3. HF, BOE, and TMAH chemical processing will be allowed as long as a buddy is present. 4. Precursors for ALD systems will be available. 5. No shipping or receiving is being done at any building on campus. 6. The custodians will not be working so restrooms will not be maintained, and sanitation of touch surfaces will not be done. * We encourage users to keep the facility clean and be extra vigilant about the hygiene and COVID risks. 7. A few engineering and building staff may walk through occasionally for major issues but availability will be very limited and could be impacted due to COVID restrictions. * Faculty and senior researchers are encouraged to be more proactive (e.g. occasional walk throughs checking the labs where there is ongoing research). Email Birck management if you notice anything.

Register today: Free, hands-on Thermo-Calc Educational Workshop on December 15th, 1:00 PM EST
by Black, Nancy Lee 13 Dec '21

13 Dec '21

Join our upcoming hands-on workshop on thermodynamics and kinetic calculations in materials science using Thermo-Calc. Motivated by integrated materials engineering (ICME) and the materials genome (MGI), the hands-on workshop will exemplify the use of Thermo-Calc in the classroom and research. The target audience is instructors, researchers and students. The academic version of Thermo-Calc is now freely available in nanoHUB through a collaboration between Thermo-Calc and nanoHUB. You can access this software by joining the Thermo-Calc group in nanoHUB: https://nanohub.org/groups/tcacademic. Title: Integrated Computational Materials Engineering in the Classroom: Teaching Fundamental Thermodynamics and Kinetics Through an Industry-Focused Lens using Free Online Simulations. Presenter: Adam Hope, PhD, Thermo-Calc Software Inc. Date/Time: Wednesday, December 15, 2021 from 1:00 PM – 2:00 PM EST Register here: https://purdue.webex.com/purdue/onstage/g.php?MTID=e1f44a88da6016a3b691b737… Abstract: Both the National Academies report on Integrated Computational Materials Engineering and the Materials Genome Initiative have highlighted the importance of linking materials, chemistry, and processing to microstructure in order to predict and engineer material properties and performance. This is especially important in the context of Industry 4.0. However, some of the challenges in implementing such an approach are: * Linking models across length scales * The lack of materials property data as a function of chemical composition and temperature * The lack of familiarity and awareness of engineers on design teams as to the different types of modeling tools which are outside their background, especially those which transcend the more traditional gaps between materials science and mechanical engineering. Modeling chemistry-process-structure relationships requires a solid foundation of thermodynamics, phase equilibria and kinetics. The CALPHAD (Calculation of Phase Diagrams) method fits this need. CALPHAD is a phenomenological approach for calculating/predicting thermodynamic, kinetic, and other properties of multicomponent materials systems. It is based on describing the properties of the fundamental building blocks of materials, starting from pure elements and binary and ternary systems. With extrapolation from the binary and ternary systems, CALPHAD predicts the properties of higher order alloys. Over the last decades, the CALPHAD method has successfully been used for development of numerous real engineering materials. CALPHAD tools are not only a critical component of any ICME framework, but they also create an opportunity to assist in teaching thermodynamics - from understanding the influence of chemistry on Gibbs free energy to constructing simple binary phase diagrams. This fundamental approach can then be extended to multicomponent systems to study real engineering materials. This presentation will demonstrate ways that Thermo-Calc can be used in the classroom, as a teaching tool, and in industry, as a research and problem solving tool for any ICME framework. Bio: Adam received his PhD in Welding Engineering at The Ohio State University. His work was focused on integrating computational and experimental techniques to predict susceptibility to weld cracking, and to develop new weld metal compositions for nuclear power applications. Adam currently works at Thermo-Calc Software providing training and applications support to users. I hope that you can join us in this workshop! Please share this invitation with others who may be interested.

Birck Distinguished Seminar, Venky Narayanamurti (Dec. 13, 3-4pm)
by Shakouri, Ali 13 Dec '21

13 Dec '21

Dear Colleagues, Prof. Venky Narayanamurti will give Birck Distinguished Seminar at 3pm on Monday Dec. 13 at Burton Morgan 121. See below the abstract of his talk. Venky will share several thought provoking ideas about the nature and nurture of discovery research. Venky’s unique perspective about basic and applied research, finding and answering questions, paradigm shifts and consolidations are important for individual researchers who care about their impact in the society and interdisciplinary centers such as Birck that bring people together to work on societal grand challenges. I encourage you to attend the seminar below and participate in the discussions afterwards. Best regards, Ali ************ Birck Nanotechnology Center Distinguished Seminar “Rethinking the Nature and Nurture of Discovery Research” Monday December 13, 2021, 3-4pm, Burton Morgan 121 with extended informal Q&A and discussion for 30m immediately following. Speaker: Venky Narayanamurti (Harvard University) Abstract: Research, particularly on the “discovery” end of the R&D spectrum, is complex and easily misunderstood. Scientific advance doesn’t always precede, it often follows, engineering advance. Answering questions isn’t always the goal, finding questions often is. We don’t always seek to strengthen conventional wisdom, sometimes we seek to surprise it. What if we could rethink research so that its nurturing, through policy and management, harmonizes with its nature? Join us for a conversation between Venky Narayanamurti and Ali Shakouri on Venky's new book<https://www.hup.harvard.edu/catalog.php?isbn=9780674251854> with Jeff Tsao, “The Genesis of Technoscientific Revolutions” (Harvard University Press, Nov 2021) addressing this question. Speaker Bio: Venkatesh Narayanamurti is Benjamin Peirce Professor of Technology and Public Policy, Engineering and Applied Sciences, and Physics Emeritus at Harvard University. He was formerly: Director of the Science, Technology and Public Policy Program at the Harvard Kennedy School (2009-2015); John L. Armstrong Professor and Founding Dean of the Harvard School of Engineering and Applied Sciences, and Professor of Physics and Dean of Physical Sciences at Harvard (1998-2009); Dean of the UCSB College of Engineering (1992-1998); VP of Research at Sandia National Laboratories (1987-1992); and researcher then Director of the Solid State Electronics Research Laboratory at Bell Labs (1968-1987). He is a Fellow of the American Academy of Arts and Sciences and an elected member of the U.S National Academy of Engineering, of the Royal Swedish Academy of Engineering Sciences and of the World Academy of Sciences.
