Water-splitting electrolysis using an electrocatalyst and a renewable power source is a promising energy conversion technology, especially when combined with energy stored in the form of hydrogen that has the benefit of also being environmentally friendly. The electrocatalyst can be rationally designed using nanomaterials spanning from transition-metal-based oxides and their derivatives, organic polymer nanomaterials, to inorganic-organic nanocomposites. The July 2020 issue of MRS Bulletin discusses materials innovations for realizing highly efficient and durable electrocatalysts for large-scale, cost-effective water splitting

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 follows each of the talks.

This webinar provides a fundamental introduction to atom probe tomography (APT) and 3D nanoscale imaging mass spectrometry, with a focus on interpreting the resultant data. Further, we explore how APT can create more efficient energy-producing materials, and how the technique can be applied to new applications. An overview of applications in metals, semiconductors, and insulators, with examples of how atom probe tomography has been applied to solve real-world problems, is provided. This introduction to the technology and applications provides insight into how you can use APT in your research. Presented by CAMECA.

Ceramics and glasses are at the forefront of advanced materials and will continue to bring new solutions to global challenges in energy, the environment, healthcare, and information/communication technology. To meet the accelerated pace of modern technology delivery, a more sophisticated approach to the design of advanced ceramics and glass materials must be developed to enable faster, cheaper, and better research and development of new materials compositions for future applications.

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 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.

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.

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.
