High-Temperature Materials for Structural Applications


Advances in metallurgy and metal mixology, together with high-performance computing, high-resolution microscopy, and advanced spectroscopy methods, reveal the potential of multicomponent advanced metals, such as multicomponent bulk metallic glasses and advanced high-entropy alloys for high-temperature structural applications. The November, 2019 issue of MRS Bulletin overviews the progress and directions for these multicomponent alloys for high-temperature structural applications.

Three-Dimensional Architected Materials and Structures


The principles of optimally engineering structures, integrating materials and architectural features at multiple length scales, are now being applied to the design and manufacture of three dimensional architected materials with properties determined a priori and attained through multiscale approaches. These materials embody the characteristics of both the constituent material, which brings the effects of its microstructure and ensuing properties at the relevant characteristic length scales, as well as the structure, which is driven by the architected design. The new 3D architected hierarchical materials offer breakthrough advances in many applications ranging from ultra-lightweight and damage-tolerant structural materials to safe and efficient energy storage, biomedical, biochemical and nanophotonic devices as well as micromechanical sensors and actuators.

This webinar expanded upon and complemented the October 2019 MRS Bulletin issue, and an interactive Q&A session with the speakers was held at the conclusion of the presentations.

Careers in Entrepreneurship (Spoiler Alert: There’s more here than launching your own start-up!)


Fancy a career in entrepreneurship? There are many pathways to explore. Yes, you can launch your own start-up or consultancy, but you can also find and create exciting careers that nurture entrepreneurship in areas as diverse as tech transfer, marketing, venture capital, and product development. In this workshop, we discussed the multitude of professional avenues you can pursue if you want to go into entrepreneurship, and how to access, position yourself for success, and advance in these roles and ecosystems. Of course, we also explored the career path of entrepreneur as well, and discussed various aspects of being a start-up success.

Phase-change Materials in Electronics and Photonics


The rapidly growing demand for data storage and processing, driven by artificial intelligence and other data-intensive applications, is posing a serious challenge for current computing devices based on the von Neumann architecture. For every calculation, data sets need to be shuffled sequentially between the processor, and multiple memory and storage units through bandwidth-limited and energy-inefficient interconnects, typically causing 40% power wastage. Phase-change materials (PCMs) show great promise to break this bottleneck by enabling nonvolatile memory devices that can optimize the complex memory hierarchy, and neuro-inspired computing devices that can unify computing with storage in memory cells.

The articles in the September, 2019 issue of MRS Bulletin highlighted recent breakthroughs in the fundamental materials science, as well as electronic and photonic implementations of these novel devices based on PCMs.

This webinar expanded upon the Bulletin issue, and an interactive Q&A session with the speakers was held at the conclusion of the presentations.

The Machine Learning Revolution in Materials Research


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.

Advances in In-situ Nanomechanical Testing


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.

Joining of Dissimilar Lightweight Materials


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.

Talk presentations:

  • Advances in dissimilar metals joining through temperature control of friction stir welding
    Kenneth Ross, Pacific Northwest National Laboratory
    Talk begins at 13:57
       
  • Ultrasonic welding of AZ31B magnesium alloy

    Talk begins at 33:00
       
  • Vaporizing Foil Actuator Welding
    Anupam Vivek, Ohio State University
    Talk begins at 59:57

Nanomaterials for Biomedical Applications


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 talks in this webinar expanded on the material presented in the Focus Issue, and an interactive Q&A session was held with the speakers following each talk.
