Metasurfaces for Flat Optics
Preview Available
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.

Can Materials Science Counter the COVID-19 Pandemic? A discussion with materials researchers at the frontlines of battling the coronavirus
Preview Available
Co-presented with SFB, the Society for Biomaterials
The spread of COVID-19 throughout the globe highlights the need for improved solutions in the fight against infectious diseases. As always, materials research plays an immense role in finding these solutions. Prevention and protection, diagnostics, therapeutics and vaccines – materials science plays a key role in each of these key components.
In this live 90-minute panel discussion, we spoke with five researchers on the frontlines of this critical battle, applying biomaterials, nanotechnology, and other tools of materials research to accelerate a solution.
This webinar brought an overwhelming amount of questions, and we are continuing the conversation on LinkedIn @COVID-19 (Coronavirus) and Materials Science. We encourage you to join the group as we resume the discussion with materials researchers at the forefront of this battle.

Nanoscale Tomography Using X-rays and Electrons
Preview Available
Three-dimensional (3D) tomographic imaging, using x-rays or electrons, of the structural, chemical, and physical properties of a material provides key knowledge that links the structure of a material to its processing, which is central to studies across a broad spectrum of materials. For decades, tomography using x-rays or electrons has proven to be an essential 3D characterization tool. In recent years, advances in technology have enabled new imaging capabilities at the nanometer or atomic scale for 3D reconstruction.
The April 2020 issue of MRS Bulletin discusses developments, techniques, and future directions for 3D tomographic imaging. This webinar expanded upon and complemented the MRS Bulletin issue with talks from leading experts in the field. An interactive Q&A session followed each of the talks.

This webinar was presented in conjunction with the Journal of Materials Research Focus Issue on Atomic Layer Deposition for Emerging Thin-film Materials and Applications. The webinar featured three presentations from authors from the Focus Issue, and each talk was followed by an interactive Q&A session with those authors.
Atomic layer deposition (ALD) is a powerful and elegant technique for depositing atomically controllable thin film materials. ALD proceeds with a unique growth mechanism relying on alternately sequential surface-controlled self-saturation reactions, which enables the atomic-scale layer-by-layer deposition of the uniformly conformal films over virtually any topologies.
Since the 2000s, ALD has greatly widened its variety of applications from semiconductors to catalysis, biomedicine, gas sensing, anti-corrosion coating, clean-energy technologies (batteries, fuel cells, supercapacitors, solar cells, etc.), and nano- and micro-electromechanical systems (N/MEMS). The characteristic merits of ALD include not only its superior controllability over film thickness, composition, and crystallinity, but also its unique capability for constructing conformal thin-film coatings on complex structures. These merits underlie the fast expansion of ALD into new areas over the past decades, such as metal-organic frameworks, two-dimensional layered materials, single-atom catalysis, solid-state batteries, and so forth.

Emergent Quantum Materials
Preview Available
The properties of quantum materials are principally defined by quantum mechanical effects at macroscopic length scales. These materials exhibit phenomena and functionalities not expected or predicted from classical physics. While the field of quantum materials has been a topical area of modern materials science for decades, today it is at the center stage of technologies ranging from electronics, photonics, energy, defense, and sensing to environmental and biomedical applications, and in particular, quantum information science and technology. The May issue of MRS Bulletin presented important developments in emergent quantum materials at the intersection of materials science and condensed-matter physics.
This webinar expanded upon and complemented the articles in this MRS Bulletin issue with talks from leading experts in the field. An interactive Q&A session will follow each of the talks.
