Metasurfaces for Flat Optics


Conventional optical components including lenses based on refraction suffer from functional degradation as the device size decreases as well as other limitations. Metasurfaces consisting of subwavelength optical antenna arrays have emerged as planar optical devices that can overcome many of the limitations of conventional lenses. Such metasurfaces enable many promising applications in lenses, holograms, and optical cloaks. These metasurfaces have been developed for their specific functionalities by exploiting new materials and design algorithms. Various optical properties such as amplitude, phase, and even frequency can be tuned by adjusting the physical shape of individual antennas and their arrangement.

The articles in the March issue of MRS Bulletin overview recent progress in and the state-of-the-art of metasurfaces and their novel applications in optics and photonics.

This webinar featured three talks from experts in the field. A Q&A session was held with each speaker at the conclusion of their talks.

Advanced Materials for Transient Electronic Devices


Transient electronics, that can disappear, dissolve, or degrade in a controlled manner over time, has been attracting significant attention as a new and emerging technology. Transient electronics has unique applications, such as bioresorbable medical devices that can provide short-/medium-term diagnosis and treatment without removal surgery, environmentally friendly devices that can physically decompose within a specific timeframe and produce no waste, and self-destructing devices for non-recoverable IT and military security systems.

    Cryogenic Electron Microscopy in Materials Science


    Cryogenic transmission electron microscopy is simply transmission electron microscopy conducted on specimens that are cooled in the microscope. The ability to probe chemistry, structure, and bonding on the atomic scale in the temperature range from a few Kelvin to room temperature in structural and functional materials in a variable temperature transmission electron microscope is an intriguing prospect that will open up many new areas of materials research. The articles in the December 2019 issue of MRS Bulletin explore the current capabilities, future developments, and opportunities for cryogenic electron microscopy in materials science.

    This webinar complemented the December 2019 issue of MRS Bulletin and featured talks from experts in the field. A Q&A session was held with each speaker at the conclusion of their talks.

    Materials for Hot-Carrier Chemistry


    The January, 2020 issue of MRS Bulletin examines the generation and relaxation of hot electrons in typical nanoparticle systems and the flow of hot electrons across the surfaces of the nanoparticles. The promise of hot-electron chemistry (and the complementary hot-hole chemistry) is supported by its application in many important reactions, including CO2 reduction, water splitting, hydrogenation, and coupling reactions, highlighting its great potential in achieving high energy-conversion efficiency and product selectivity.

    This webinar featured three talks from experts in the field. A Q&A session was held with each speaker at the conclusion of their talks.

    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.

    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.
