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.

Can Materials Science Counter the COVID-19 Pandemic? A discussion with materials researchers at the frontlines of battling the coronavirus

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.

Nanoscale Tomography Using X-rays and Electrons

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.

Atomic Layer Deposition for Emerging Thin-film Materials and Applications

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.
