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).

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

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.

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):

Mask Protocols in the Cleanroom
We have observed various masking practices in the cleanroom recently so as a reminder for those using our Birck cleanroom, please continue to follow our COVID mask protocols. Masking requirements are either to use an M3 N95 mask by itself or use a standard mask under the cleanroom veil. If you have any questions please contact a staff member.
Thanks,
Ron

Graduate Research Assistantship Opportunity:
Deposited Gate Oxides for SiC MOSFETs
Up to two graduate research assistantships are available in the area of silicon carbide metal-oxide-semiconductor (MOS) devices. SiC is a wide bandgap semiconductor with a high critical field, making it an exciting material for power electronic devices. SiC MOSFETs are now commercially available, but do not yet achieve their full potential. Our group is approaching this problem from several directions, including a new device trench MOSFET geometries inspired by modern FinFETs and alternative gate insulator fabrication methods.
Research activities will include fabrication and characterization of SiC MOS capacitors and MOSFETs with gate oxides formed by thermal oxidation, atomic layer deposition (ALD), and other methods. The student will gain a detailed understanding of the physics of the MOS interface and will learn various methods of characterizing devices, including MOS CV analysis, interface state density and carrier mobility.
