Northwestern University's ETOPiA (Engineering Transdisciplinary Outreach Project in the Arts) presents Science on Screen:
The Bit Player (2018)
A film by Mark A. Levinson
Director of the award-winning film Particle Fever
Each film screening will be followed by a faculty-led discussion.In a blockbuster paper in 1948, Claude Shannon introduced the notion of a "bit" and laid the foundation for the information age. His ideas ripple through nearly every aspect of modern life, influencing such diverse fields as communication, computing, cryptography, neuroscience, artificial intelligence, cosmology, linguistics, and genetics. But when interviewed in the 1980s, Shannon was more interested in showing off the gadgets he’d constructed — juggling robots, a Rubik’s Cube solving machine, a wearable computer to win at roulette, a unicycle without pedals, a flame-throwing trumpet — than rehashing the past. Mixing contemporary interviews, archival film, animation and dialogue drawn from interviews conducted with Shannon himself, The Bit Player tells the story of an overlooked genius who revolutionized the world, but never lost his childlike curiosity.

lessAbstract: Current understanding of using energy releases for both fields of experimental damage mechanics or induced seismicity primarily focuses on parametric analysis, e.g., individual traits of energy releases such as magnitude and rate of release. But the extensive information embedded in the organizational patterns of energy releases has hardly been explored. Here we study the specific organizational signatures that they possess. A key theme to this work is to show that energy release organizational signatures (topology) are physically connected to fundamental mechanisms of fracture and slip—but demands a perspective shift to an interdisciplinary approach that combines mechanics and data science. We move from understanding energy releases in time only, to connecting them in space-time-magnitude-mechanism and understanding the shape of these multi-dimensional networks as tree structures and their evolution. This presentation will demonstrate the analyses that extend single scale acoustic emission (AE) data into multi-scale connected networks that can inform our understanding of stress evolution.
Bio: Jesse Hampton is an Assistant Professor in Civil and Geological Engineering (Department of Civil and Environmental Engineering) at the University of Wisconsin-Madison. At the intersection of humanity, Earth systems, and the infrastructure needed for travel and power generation, there exists an interdisciplinary field where civil engineering, geological engineering, sustainability, geophysics, and data science are inextricably linked. At this intersection, Dr. Hampton's research focuses on a few cross-cutting themes including multiscale damage (e.g., from microcracks to earthquakes), nondestructive evaluation (NDE) techniques (e.g., from acoustic emissions (AEs) to distributed fiber optic sensing), and artificial intelligence (e.g., from optimization to deep learning). The goal of Dr. Hampton's research is to predict and mitigate damage in Earth and Civil Engineering systems from the micro- to field-scales to enhance infrastructure sustainability. Prior to joining the UW-Madison faculty, Dr. Hampton worked in geomechanics and geophysics research for both Halliburton and New England Research. He obtained his PhD in 2015 from Colorado School of Mines. Google Scholar: https://scholar.google.com/citations?user=mbTGfxsAAAAJ&hl=en. Research Group Website:https://geod.wisc.edu/

lessTitle: X-ray fluorescence microscopy for life and environmental studies at the Advanced Photon Source
Abstract: Trace elements, particularly metals, play very important roles in a large variety of biological and environmental systems. Approximately 40% of all enzymes require certain trace metals as part of their catalytic centers. Hard X-ray fluorescence microscopy (XFM) is one of the most sensitive techniques for studying trace metals in complex systems, such as biological tissues, cells, soil aggregates, etc. In this presentation, I will discuss the XFM capabilities at the Advanced Photon Source (APS) of Argonne National Laboratory, which offer a range of spatial resolutions from 10s of microns to sub-100 nm, covering the needs of studies at multiple length scales. I will also introduce the Bionanoprobe (BNP) instrument, the first of its kind XFM instrument with cryogenic capabilities, dedicated to studying biological systems at a sub-cellular level. The cryogenic capabilities, including a cryogenic sample environment and cryogenic sample transfer mechanism, allow biological samples to be measured in their frozen hydrated state, where the ultrastructure and elemental distributions are preserved closest to their natural state. Over the past decade, we have implemented XFM tomography, ptychography imaging, and in-line optical fluorescence imaging capabilities at the BNP, enabling multi-modality analysis on the same platform. Currently, the second-generation BNP instrument is under development and scheduled to be completed in 2025, with the primary goal of utilizing the APS-Upgrade synchrotron source and delivering a 10 nm spatial resolution.
Bio: Dr. Si Chen is Physicist and Beamline Scientist at the Advanced Photon Source (APS) of Argonne National Laboratory. Her research focuses on elemental imaging for life and environmental sciences with hard X-ray fluorescence microscopy (XFM). Dr. Chen joined Argonne in 2011 and commissioned the Bionanoprobe (BNP) instrument, i.e., the first of its kind nanoscale XFM with cryogenic capabilities. She is currently leading the user program centered around the BNP, as well as the efforts for developing the next-generation XFM instrumentation. Prior to joining Argonne, she received her PhD in Materials Engineering at Dartmouth College, where she studied snow metamorphism.

lessAbstract: Grain boundaries have a central importance for functional properties of materials. They can critically control thermal and elactrical transport, determining the performance of energy and electronic materials. In thermoelectric materials – promising for refrigerant-free cooling and waste heat energy harvesting – grain boundaries can be leveraged to suppress the thermal conductivity, but can also detrimentally suppress the carrier mobility. Grain boundaries are not all equal: they are associated to several degrees of freedom, and can come in multiple orientations, symmetries, and chemistries. Recent evidence suggests that some types of grain boundaries could be more beneficial than others for the thermoelectric performance. Despite the importance, we lack a clear understanding of how grain boundaries modify the microscale transport owing to the scarcity of local investigations. Usually the role of grain boundaries is inferred from bulk, effective measurements. However, understanding how grain boundaries impact transport locally is a crucial perspective to enable grain-boundary engineering for the next generation of high-performance thermoelectrics.
In this seminar, I will introduce our recent work on thermal conductivity imaging of grain boundaries via spatially-resolved frequency-domain thermoreflectance. Measurements with microscale resolution reveal a suppression in thermal conductivity at grain boundaries both in thermoelectric SnTe and photovoltaic multicrystalline silicon. In contrast to conventional thermal modeling, which assumes that all boundaries are perfect scatterers and lead to uniformly suppressed thermal conductivity, we observe a non-uniform suppression localized within a few microns of a boundary. Furthermore, not all grain boundaries behave the same: misorientation angle, symmetry, as well as interface roughness and morphology are found to strongly correlate with the effective thermal boundary resistance. Extracting transport properties from microscale imaging can provide comprehensive understanding of how individual microstructural components work. In particular, it can advance the study of grain boundary phases - i.e. two-dimensional phases stabilized at the boundary and that can be controlled via thermodynamics - by correlating how thier local chemistry and structure impact functional properties. This development can improve our understanding of carrier-defect interactions, enabling the rational engineering of interfaces and materials microstructures for superior performance in energy and electronics.
Bio: Eleonora Isotta is currently a Postdoctoral scholar in the Department of Materials Science and Engineering at Northwestern University. She joined in fall 2022 and has been working on thermal transport in semiconductors, developing methods to perform thermal imaging of defects, with a focus on grain boundaries, together with Prof. G. J. Snyder and Prof. O. Balogun. She received her B.S. in Environmental Engineering in 2015 and M.S. in Energy Engineering in 2017 from University of Trento. In 2021, she received a Ph.D. in Materials Science from University of Trento, with a dissertation on the interplay between crystal structure and transport properties in thermoelectric materials. She then pursued a Postdoc at Michigan State University working on thermal transport and elasticity in thermoelectric materials. Her current research interests involve thermal transport, microstructure engineering, and materials for thermoelectrics and electronics.

lessTitle: Mechanism-based multi-scale models for damage and failure in heterogeneous materials
Abstract: A large variety of modern engineering materials such as polymers and their composites (unidirectional, textile, nanocomposites) have a heterogeneous microstructure. As a result, their failure behavior under multi-axial stresses is highly complex, consisting of multiple simultaneous meso-scale damage mechanisms. Moreover, the heterogeneous microstructure also makes the fracturing distinct quasi-brittle character (neither fully brittle nor fully ductile). This has important implications on structural behavior, especially in terms of size effects in strength and fracture toughness. Since structural designs often rely on numerical modeling, an accurate prediction of load-bearing capacities and energy dissipation during these failures is essential. This talk will focus on the class of semi-multiscale constitutive models called the microplane models (pioneered at Northwestern), which effectively address this challenge. These models have a dual-scale architecture, and can reproduce complex macro-scale behaviors via simple, intuitive formulation of meso-scale damage mechanisms. They also provide a physically sound basis to homogenize the meso-scale damage to predict the macro-scale failure growth and structural size effects. They are thus an effective strategy for multi-mechanism failures in heterogeneous materials. First, we will introduce the quintessential spherical microplane model, first developed for concrete, and applicable in general to isotropic materials. We will present its application to the failure of brittle-plastic polymers and demonstrate its abilities to capture complex aspects such as tension-compression asymmetry and pressure sensitivity. Next, we will introduce the cylindrical microplane model, which applies to unidirectionally reinforced polymer composites, which are transversely isotropic. We will present a successful application of this model to compression induced kink band failures. Following that we will introduce the microplane triad model, which applies to textile composites, which are orthotropic and have additional complexities due to yarn undulations. We will demonstrate its successful application to prediction of ballistic impact of woven composite lamina. Lastly, we will discuss the challenges of applying these models to real world applications and directions for future work.
