Machine learning (ML) and artificial intelligence (AI) are quickly becoming common-place in materials research. In addition to the standard workflow of fitting a model to a large set of data in order to make predictions, the materials community is finding novel and meaningful ways to integrate AI within their work. The July, 2019 issue of the MRS Bulletin highlighted a few of these applications.  The articles in the issue show that AI/ML is delivering real-world, practical solutions to materials problems, and we need AI/ML methods and models that are more fluent in materials science.

The talks in this webinar expanded on the material presented in the MRS Bulletin issue as well as the MRS Communications Special Issue on Artificial Intelligence.   An interactive Q&A session was held with the speakers following each talk.

The June, 2019 issue of MRS Bulletin focused on Advances in In-situ Nanomechanical Testing. In situ nanomechanical testing can provide critical insights into the fundamental processes that lead to deformation phenomena in materials. Simultaneous observations of deformation phenomena and measurements of mechanical response in situ allow for nanomechanical testing information to be connected to models to elucidate the subtlety and complexity of how materials respond to stress and strain. Discussion on the current state of the art for in situ nanomechanical testing and future opportunities in imaging, strain sensing, and testing environments are also addressed in this issue of MRS Bulletin.

The transportation sector is the largest contributor to greenhouse gas emissions in the United States. Because it takes less energy to move a lighter object, even small reductions in weight can have a significant effect on the fuel consumption and emissions of the transportation sector. Lightweight materials of interest include advanced high-strength steel, aluminum, magnesium, polymer composites, and multi-material structures. Assembling multi-material structures is challenging due to differences in melting temperature, formation of intermetallic compounds, differences in coefficient of thermal expansion, and galvanic corrosion potential.

While the number of joining techniques available to the transportation industry grows, for high-volume production, there is a continued desire for a single joining method that can assemble advanced high-strength steel, aluminum, magnesium, and composite materials consistently and robustly.

The theme of the August, 2019 issue of MRS Bulletin is "Joining of Dissimilar Lightweight Materials." This webinar will expand upon the Bulletin issue, and an interactive Q&A session with the speaker will be held at the conclusion of the presentation.

Nanotechnology has been responsible for an unprecedented positive impact in healthcare advances, by merging fundamental and applied sciences as complementary tools envisioning an enhanced quality of life. Recently, a broader spectrum of high performance nanomaterials and material-based nanosystems has been engineered to address challenges in medical and health-related fields. At the same time, there has been a shift in importance from designing exclusively bioinert materials to instead producing complex bioactive building blocks for mimicking targeted functions.

The June, 2019 Journal of Materials Research (JMR) Focus Issue is devoted to the latest advances in biomedical nanomaterials, including: (i) different fabrication approaches and applications, (ii) design and characterization of novel biomedical materials and devices as well as their structure-property relationships with biological responses, and (iii) novel (bio)-nanomaterials as potential candidates to integrate multifunctional devices targeting self-assembly materials.

The coupling of acoustic energy with materials structures and processes is at the core of current and emerging application areas, such as ultrasound-enabled materials characterization, structuring, and processing. High concentration of acoustic energy has been shown to provide conditions for the synthesis of unusual material phases and structures, while reports on acoustic activation of surface diffusion, desorption, and catalysis hold high promise for applications where heating must be avoided or rapid switching of surface conditions is required. Some of the recent scientific and technical advances in the general area of acoustically enabled material synthesis, processing, and characterization are reviewed in the May, 2019 issue of MRS Bulletin.

The March 2019 issue of MRS Bulletin focused on recent developments in porphyrin nanomaterials, and their applications in energy harvesting and biomedicine. Porphyrins are plane macrocyclic molecules containing four pyrroles connected in ring fashion through four methine carbons at their α-positions. They are present in almost all living organisms in one form or another, such as chlorophyll and heme. Porphyrins are important participants in the energy supply system for both earth and life, in the forms of photosynthesis and oxygen transport. Porphyrin nanostructures can be synthesized by self-assembly methods and have various applications including in solar-energy harvesting, water splitting, environmental pollutant reduction, and nanomedicine for tumor therapy.

The creation of new materials capable of performing life-like functions inspired by biology, such as complex and cooperative processes, self-replication, and self-repair, will ultimately rely upon incorporating biological principles of spatiotemporal modes of self-assembly. Elucidating fundamental principles for the design of such out-of-equilibrium dynamic self-assembling materials systems is the focus of the February, 2019 issue of MRS Bulletin.

This webinar expanded on the Bulletin issue, and an interactive Q&A was held with each of the speakers following their talks.
