MSEE Research Published in Journal of Applied Physics

Research from MSEE URA Research Area 4: Photon Material Interactions was recently published by the Journal of Applied Physics. The article, titled “Time Resolved X-ray Diffraction in Shock Compressed Systems”, can be found in print (Vol.129, Issue 4) and online https://doi.org/10.1063/5.0034929.

In the paper, the authors give a perspective on the topic of time resolved x-ray diffraction in shock compressed systems with the goal of highlighting results in this rapidly growing field and placing them in the context of what can be learned from these techniques. While the primary focus is on x-ray diffraction, other time resolved x-ray techniques are included as well.

“Time resolved x-ray diffraction is a key tool for characterizing the interaction of light with materials in shocked systems,” said LLNL physicist Harry Radousky, lead author of the paper.  “As the MSEE work moves forward, understanding the shock drivers and x-ray capabilities at the diverse set of facilities available will become an increasingly important planning feature both in RA4 as well as other connected research areas.”

Congratulations to MSEE URA PI Harry Radousky of Lawrence Livermore National Laboratory and his co-authors Michael Armstrong and Nir Goldman on this publication.

Workforce Development: Storytelling in Science

There are more opportunities than ever for us to communicate our science: Talks, papers, and posters, of course, but also social media and blogs. Effective communication is particularly important for students, not only to make their work more influential but also as advertising to potential employers and collaborators. But how many times have you watched a scientist ramble through an interminable series of slides and wondered, “What is the point of all of this?”

Don’t be that speaker. Learn how to give a great talk (or write a great paper) by using the basic building blocks of storytelling — momentum, conflict, and resolution — to craft a compelling narrative for your work. Using techniques described by Randy Olson in his book Houston, We Have a Narrative: Why Science Needs Story, we’ll learn to tell the difference between good and bad scientific storytelling and use that understanding to develop narrative structures that will capture an audience’s attention.

Todd Hufnagel has a long-standing interest in helping students learn to communicate their work through effective speaking and writing. He is Professor of Materials Science and Engineering and Mechanical Engineering, Associate Director of the Materials Science in Extreme Environments University Research Alliance and HEMI Fellow.

Workforce Development: Technical Presentations – How to Grab (and Keep) Your Audience’s Attention

As researchers we are called upon regularly to present our work to a variety of audiences. Do you finish your presentations feeling like your audience learned more about you and your research? Or did you get the sense they were confused, bored and maybe even sleeping? This session will discuss ways in which we can all improve our presentations to a wide range of audiences. Group discussion will be interspersed with segments from a video by Julie Reiser in the Center for Leadership Education on the “Top 10 Mistakes Most Communicators Make”. Together we will identify practices that will (and maybe won’t) work for our own technical presentations, helping all of us to put our best foot forward.

Lori Graham-Brady, Associate Director of the Hopkins Extreme Materials Institute and Professor and Chair of the Department of Civil and Systems Engineering at Johns Hopkins, will be hosting this session. Professor Graham-Brady is a leading global researcher in the field of computational stochastic mechanics, multiscale modeling of materials with random microstructure, and the mechanics of failure under high-rate loading.

The Hopkins Extreme Materials Institute (HEMI) and Materials Science in Extreme Environments University Research Alliance (MSEE URA) are hosting a career panel where you can learn about careers for PhDs in industry, including how to look for (and get!) a job in industry, how the demands and expectations for PhDs in industry are different from academia, and work-life balance. Each of our panelists is a recent PhD graduate or post-doc who has made the transition to industry and can offer advice for others looking to do the same. Most of the discussion will be devoted to Q&A, so come prepared to ask anything that’s on your mind!

MSEE Seminar: Prof. Steve Son, “Engineering Energetic Materials”

Join us for a seminar with Professor Steve Son, Alfred J. McAllister Professor of Mechanical Engineering at Purdue University, titled “Engineering Energetic Materials.”

The seminar will begin at 3pm ET on Tuesday, November 3, 2020. It will be held via Microsoft Teams.

Abstract: Traditionally, energetic materials (propellants, explosives and pyrotechnics) have been mostly CHNO molecules synthesized chemically and mixed with polymers to form composites that are cast or pressed into final form. This continues to be an exciting area and many new materials are being developed and characterized. However, the focus of this presentation is an overview of our efforts at engineering new energetic materials rather than by chemical approaches. This includes fabricating piezoelectric energetic materials, developing scalable methods to introduce nanoscale features in full density micron-scale particles, blending pyrotechnic elements into propellants to achieve unique combustion, and assembling complex structures with additive manufacturing to enable function. Some fluoropolymer materials can be poled, and when combined with fuels, such as aluminum become energetic. Our recent work has explored how these multifunctional materials might be exploited to enable external control of burning rate and ignition. Mechanical activation or arrested ball milling is an example of engineering particles in traditional sizes, but with nanoscale features. We have also formed engineered crystalline materials by controlled encapsulation of particles and by subtractive methods (microscale machining and femtosecond laser machining). Likewise, we are exploring the interaction of fast burning pyrotechnics, or reactives, into propellant materials to tailor output. We term this “reactive wires”, in contrast to the inclusion of inert wires into propellants to enhanced the effective burning rate. Additive manufacturing (AM) of energetic materials represents an attractive avenue to tailoring the properties and performance of energetic systems by enabling precise control of the microstructure of additively manufactured components. Examples of recent results in each of these areas will be presented, and future directions will be discussed.

MSEE Seminar: Prof. Dana Dlott, “Watching Solids and Liquids Through the Ultrafast Shock Compression Microscope”

Join us for a seminar with Professor Dana Dlott, Emeritus Professor of Chemistry and Professor of Materials Research at the University of Illinois, titled “Watching solids and liquids through the ultrafast shock compression microscope.”

The seminar will begin at 3pm ET on Tuesday, October 6, 2020. It will be held via Microsoft Teams.

Abstract: We have developed a microscope that looks into solids and liquids as they are subjected to controlled high velocity impacts from laser-launched flyer plates. This convenient tabletop microscope set up allows us to perform well-characterized controlled shock experiments on tiny samples hundreds of shots per day. The flyer plates move a few kilometers per second, creating intense mechanical and thermal effects that can trigger new kinds of chemistry. One of these impacts can create pressures of 200,000 atm and temperatures of 4000K while compressing matter to half its density. In this talk, I will describe the shock compression microscope and the peripheral high-speed optical diagnostics that measure pressure, temperature, density and composition in real time. I will mention applications ongoing in my lab, such as metal-organic frameworks as shock energy absorbers, proteins under shock compression and molecular photophysics in shock-compressed matter. Then I will discuss shock initiation and detonation of high explosives, including liquid explosives and plastic-bonded explosives. This shock compression microscope has many applications in chemistry, physics, materials science and biology and it lets us see right inside detonating high explosives with high time and space resolution.

Speaker Bio: Dana Dlott is the William H. and Janet G. Lycan Emeritus Professor of Chemistry and a Professor of Materials Research at the University of Illinois. He received a bachelor’s degree from Columbia University and a Ph.D. from Stanford University under the supervision of Prof. Michael Fayer, using ultrafast laser spectroscopy to study electronic energy transfer in molecular materials. After he joined the Chemistry Department at the University of Illinois (in 1979) he began a research program to study vibrational relaxation in solids. About 30 years ago he began to study shock waves in solids. Dlott is a Fellow of the American Physical Society, the Optical Society of America and the American Association for the Advancement of Science. He has been recognized with the ACS award in Experimental Physical Chemistry and the Lippincott prize of the OSA for his work in ultrafast vibrational spectroscopy. He is a former Chair of the APS Topical Group on Shock Compression in Condensed Matter and the author of 325 scientific publications.
