Microscopy is All You Need. Prof. Sergei Kalinin | University of Tennessee, Knoxville

Microscopy is All You Need. Prof. Sergei Kalinin | University of Tennessee, Knoxville

Abstract: : Machine learning and artificial intelligence (ML/AI) are rapidly becoming an indispensable part of physics research, with domain applications ranging from theory and materials prediction to high- throughput data analysis. Over the last several years, increasing attention is attracted to the use of AI interacting with physical system as a part of active learning – including materials discovery and optimization, chemical synthesis, and physical measurements. For these active learning problems, microscopy arguably represents an ideal model application combining aspects of materials discovery via observation and spectroscopy, physical learning with relatively shallow priors and small number of exogenous variables, and synthesis via controlled interventions. In this presentation, I will discuss recent progress in automated experiment in scanning probe and electron microscopy, ranging from feature to physics discovery via active learning. The applications of classical deep learning methods in streaming image analysis are strongly affected by the out of distribution drift effects, and the approaches to minimize though are discussed. I will further illustrate transition from post-experiment data analysis to active learning process, including learning structure-property relationships and materials discovery in composition spread libraries. Here, the strategies based on simple Gaussian Processes often tend to produce sub-optimal results due to the lack of prior knowledge and very simplified (via learned kernel function) representation of spatial complexity of the system. Comparatively, deep kernel learning (DKL) and structured Gaussian Processes methods allow to realize both the exploration of complex systems towards the discovery of structure-property relationship and enable automated experiment targeting physics (rather than simple spatial feature) discovery. The latter is illustrated via experimental discovery of ferroelectric domain dynamics in piezoresponse force microscopy. For probing physical mechanisms of tip-induced modifications, I will demonstrate the combination of the structured Gaussian process and reinforcement learning, the approach we refer to as hypothesis learning. Here, this approach is used to learn the domain growth laws on a fully autonomous microscope. The future potential of Bayesian active learning for autonomous microscopes is discussed. These concepts and methods can be extended from microscopy to other areas of automated experiment.

High-throughput Materials Synthesis in Atomic Layer Processing. Professor David Bergsman | University of Washington

Welcoming our AI Overlords: Operationalizing Machine Learning for Materials Discovery and Design. Dr. Steven R. Spurgeon | Pacific Northwest National Laboratory and University of Washington

High-throughput Materials Synthesis in Atomic Layer Processing. Professor David Bergsman, University of Washington

Abstract: Recent years have seen a surge of interest in the development of scalable tools for nanomaterials synthesis. Many emerging technologies, like solar cells, batteries, catalysts, and membranes, rely on atomically-precise materials design to operate effectively. Tools for creating these materials with increased scalability and decreased costs are thus required to enable the widespread adoption of these technologies. One suite of tools, known collectively as atomic layer processing (ALP), is particularly interesting for nanomaterials synthesis, due to its ability to create ultrathin films with sub-nanometer thickness and compositional control. ALP has also been used in the semiconductor industry over several decades, making it easy to deploy in other manufacturing processes. Commercial solar panels and battery electrodes have already started to incorporate ALP-deposited films as passivation layers. However, as demand for nanotechnology increases, there is a continued need to expand the library of materials that can be made with these tools and to accelerate the pace with which these materials are deployed. This presentation will highlight how the Bergsman Research Group at the University of Washington is expanding the applicability of ALP by creating new processes with higher-throughput screening tools. We will describe some of the use cases of ALP in semiconductor processing, catalysis, and membrane separations, along with the challenges associated with making new materials processes with these tools. Then, we will discuss existing methods for more rapid deployment of new processes. Finally, we will discuss our work to speed up materials development using a high-throughput reactor, along with our efforts to implement a connected data pipeline for easier analysis of process parameters.

Welcoming our AI Overlords: Operationalizing Machine Learning for Materials Discovery and Design. Dr. Steven R. Spurgeon | Pacific Northwest National Laboratory and University of Washington

Abstract: Artificial intelligence (AI) promises to reshape scientific inquiry and enable breakthrough discoveries in areas such as energy storage, quantum computing, and biomedicine. While it is now possible to produce nanomaterials in almost limitless configurations, engineering of desirable functionality depends on precise control of atomistic structure and defects. Complex synthesis pathways can lead to significant deviations from idealized structures, which occur at length scales that are challenging to probe experimentally and theoretically. Mastery of materials is therefore predicated on the ability to acquire and interpret complex, heterogeneous, and fast-evolving data streams, a task uniquely suited to emerging AI and machine learning methods. Here I will discuss our efforts to develop a new framework for materials discovery in the electron microscope, leveraging low-level system automation, domain-grounded data pre-processing, and emerging sparse data analytics to extract truly statistical insights. I will discuss the current and future potential of this platform to both unlock experimentation at scale and derive richer, more meaningful physical models for important material systems.

Machine-learning-guided descriptor selection for predicting corrosion resistance in multi-principal element alloys. Dr. Ankit Roy | Pacific Northwest National Laboratory

Shining light on perovskites. Prof. Rob Berger | Western Washington University

Abstract: Compounds crystallizing in the ABX3 perovskite structure are studied for many applications, including solar energy conversion. This class of materials includes both lead-halide perovskites that absorb light in photovoltaic solar cells (e.g., CH3NH3PbI3) and transition metal-oxide perovskite photocatalysts (e.g., SrTiO3). One reason for the technological versatility of perovskites is that their composition and structure, and consequently their electronic properties, are highly tunable. These compounds can be engineered through elemental substitution, strain, layering, and defects, allowing for the optimization of their properties. I will summarize our group’s work over the past several years, in which we use density functional theory (DFT) calculations to explore how changes in composition and atomic structure affect the electronic structure and properties of perovskites for solar energy conversion. This work has led us to both fundamental understanding and concrete predictions of new materials.

Machine-learning-guided descriptor selection for predicting corrosion resistance in multi-principal element alloys. Dr. Ankit Roy | Pacific Northwest National Laboratory

Abstract: More than $270 billion is spent on combatting corrosion annually in the USA alone. As such, we present a machine-learning (ML) approach to down select corrosion-resistant alloys. Our focus is on a non-traditional class of alloys called multi-principal element alloys (MPEAs). Given the vast search space due to the variety of compositions and descriptors to be considered, and based upon existing corrosion data for MPEAs, we demonstrate descriptor optimization to predict the corrosion resistance of any given MPEA. Our ML model with descriptor optimization predicts the corrosion resistance of a given MPEA in the presence of an aqueous environment by down selecting two environmental descriptors (pH of the medium and halide concentration), one chemical composition descriptor (atomic % of element with minimum reduction potential), and two atomic descriptors (difference in lattice constant (Δa) and average reduction potential). Our findings show that, while it is possible to down select corrosion-resistant MPEAs by using ML from a large search space, a larger dataset and higher quality data are needed to accurately predict the corrosion rate of MPEAs. This study shows both the promise and the perils of ML when applied to a complex chemical phenomenon like the corrosion of alloys.

Accelerating Atomistic Simulations of Solid-Phase Processing with Neural Network Potentials. Dr. Jenna Pope | Pacific Northwest National Laboratory

Abstract: Neural network potentials (NNPs) can greatly accelerate atomistic simulations, allowing one to sample a broader range of structural outcomes than possible with ab initio methods. This talk presents an active sampling algorithm to train an NNP that shows DFT-level accuracy in dynamic shear simulations of a model Cu-Ni multilayer system. We then use the NNP in conjunction with a perturbation scheme to stochastically sample structural and energetic changes caused by shear-induced deformation, demonstrating the range of possible intermixing and vacancy migration pathways that can be obtained as a result of the speedups provided by the NNP.

Differential Property Prediction: A Machine Learning Approach to Experimental Design in Advanced Manufacturing. Loc Truong | Pacific Northwest National Laboratory

Abstract: Advanced manufacturing techniques have enabled the production of materials with state-of-the-art properties. In many cases however, the development of physics-based models of these techniques lags behind their development in the lab. This means that material and process development proceeds largely via trial and error. This is sub-optimal since experiments are cost-, time-, and labor-intensive. In this work we propose a machine learning framework, differential property classification (DPC), which enables an experimenter to leverage machine learning's unparalleled pattern matching capability to pursue data-driven experimental design. DPC takes two possible experiment parameter sets and outputs a prediction of which will produce a material with a more desirable property specified by the operator. We demonstrate the success of DPC on AA7075 tube manufacturing process and mechanical property data using shear assisted processing and extrusion (ShAPE), an emerging solid phase processing technology. We show that by focusing on the experimenter's need to choose between multiple candidate experimental parameters, we can reframe the challenging regression task of predicting material properties from processing parameters, into a classification task on which machine learning models can achieve good performance.

Making Machine Learning and Explainable Artificial Intelligence Work for Chemistry. Dr. Johannes Hachmann | University at Buffalo

Abstract: The use of modern machine learning, informatics, and data mining approaches is a relatively new development in the chemical and materials domain. These techniques have been exceedingly successful in other application fields, and since there is no fundamental reason why they should not have a similarly transformative impact on chemical and materials research, there is now a concerted effort by the community to introduce data science in this new context. They hold tremendous promise for the practical realization of accelerated discovery and inverse design. However, adapting techniques from other application domains for the study of chemical and materials systems requires a substantial rethinking and redevelopment of the existing methods.

Well-calibrated and domain-informed deep learning methods for quantifying the change in microstructural features post-radiation on LiAlO2 pellets. Dr. Karl Pazdernik | Pacific Northwest National Laboratory

Abstract: LiAlO2 is an important material that is used as a tritium producer for the Tritium Modernization Program. To better understand the tritium release from the material during irradiation, a comprehensive microstructural analysis of unirradiated and irradiated LiAlO2 is required. Recently, deep learning has been employed as a fast approach to classifying various microstructural features in LiAlO2 pellets that are visualized by scanning electron microscopy (SEM), including grains, grain boundaries, voids, precipitates, and zirconia impurities. While these methods can produce high overall accuracy, it can also decrease significantly when the SEM image is collected under different conditions and while the overall accuracy may remain high, challenging regions such as the boundaries between microstructural features may be predicted with much higher error. To be more robust to image variability and properly quantify regions of lower confidence, we present a well-calibrated and domain-informed deep learning approach to semantic segmentation of SEM images which includes uncertainty quantification and allows for comparison across multiple SEM images. We highlight areas where prediction is less certain and summarize the effects of radiation on LiAlO2.

Deep Learning Tools for Advanced Manufacturing Applications. Dr. Keerti Kappagantula | Pacific Northwest National Laboratory

Abstract: Several advanced manufacturing techniques, such as solid phase processing or additive manufacturing, are of great interest to industry given their ability to achieve components with never-seen-before properties, forms and/or energy efficiency. However, most of these approaches are also associated with emerging computational capabilities owing to their nascent stage of development. As such, often design of experiments or property predictions corresponding to a specific process regime/form factor/feedstock is Edisonian in nature. In such situations, machine learning and artificial intelligence tools provide a viable pathway for data driven analysis for predicting process conditions or optimal performance metrics of interest. Additionally, development of such surrogate models may also accelerate technology deployment while accelerating the R&D cycle. This walk will provide some recent examples of the different machine learning tools deployed in advanced manufacturing regimes. The advantages and limitations of such approaches and their adoption in manufacturing industry will also be discussed.

Modeling Solid Phase Processes with Physics Informed Machine Learning for Prediction and Control. Ethan King | Pacific Northwest National Laboratory

Abstract: Solid phase processes plunge a rotating tool into source material to heat and remodel the material to achieve desired properties and conformations. Temperature during processing is tightly linked to microstructure formation and thus final material properties but is difficult to model due to the complex thermo-mechanical feedbacks that determine generation of heat. This talk presents the use of both neural ordinary differential equations and partial differential equation models that capture known physics to leverage limited data for learning the relationship between process inputs and temperature. We show that these approaches can closely fit measurement data and be used to design process controls.

Characterizing crystallization kinetics and properties of thermoplastic composites. Prof. Mark Peyron | Western Washington University

Mathematical frameworks for comprehensively exploring process parameter/property relationships in advanced manufacturing. Dr. Henry Kvinge | Pacific Northwest National Laboratory

Abstract: Advanced manufacturing holds the promise of producing materials with critically needed properties. To take advantage of this opportunity however, researchers need to be able to understand how the process parameters which define the manufacturing process relate to the end properties of the material. Since many different process parameters could theoretically yield the same property, the standard machine learning approach would be to train a model that, given a set of process parameters as input, predicts material properties as output (e.g., regression or classification). This however is only of modest help when the real goal is to understand the distribution of all process parameters that lead to the desired property, allowing the materials scientist to choose the one that satisfies a range of other criteria that they may have. This latter problem requires the training of a generative “inverse model”, that can learn multiple process parameter distributions. In this talk we discuss current progress on this problem using the topological construction of a fiber bundle.

Bio: Henry Kvinge is a mathematician/data scientist at Pacific Northwest National Lab. He works at the intersection of deep learning and mathematics with a special interest in understanding how machine learning can be adapted to handle the uncertainties and ambiguities of the real world.

Characterizing crystallization kinetics and properties of thermoplastic composites. Prof. Mark Peyron | Western Washington University

Abstract: Thermoplastic composites are increasing important in aerospace, automotive, and other industrial applications. But the necessary detailed processing understanding lags that of thermosetting composites (such as carbon-epoxy systems). In thermosets, a rich understanding of cure kinetics is key to understanding and modeling the composite properties. For thermoplastic composites, mechanical, heat transfer, flow, and deformation properties are important to characterize, but the critical kinetic process for most materials of interest is crystallization. Crystallization kinetics are most-commonly studied using isothermal differential scanning calorimetry, but there are numerous challenges and problems with this approach. Alternatively, dynamic DSC studies offer opportunities for more complete and more consistent kinetic characterization. We have been investigating experimental and modeling approaches that reduce uncertainty, suppress user subjectivity, and allow estimation of prediction uncertainty using novel experimental and analysis techniques. A case study based on unidirectional carbon fiber tape prepreg with a high-performance poly(ether ketone ketone) resin (CF-PEKK) will be presented and contrasted with unreinforced PEKK resin. Uncertainty in data, modeling, and predictions will be addressed.
