Perovskite Photovoltaics


Perovskite solar cells are one of the hottest topics today in materials research. Perovskite materials are inexpensive to produce and simple to manufacture. They have witnessed unprecedented progress since initial seminal work in 2009. After key breakthroughs with solid-state perovskite photovoltaics in 2012, research efforts have grown exponentially, and several groups have demonstrated that the perovskite acts as a light absorber and a charge transporter, where the perovskite layer can be deposited using a broad range of techniques. By optimizing the material quality, a remarkable power-conversion efficiency of over 20% has been demonstrated, highlighting the exceptional photovoltaic properties of perovskite materials.

This webinar, complementing the August issue of MRS Bulletin, will highlight various synthesis methods and properties of perovskite solar cells.

Biomineralization


Biomineralization is the process by which living organisms orchestrate the synthesis and organization of minerals (biominerals), which can be viewed as an ancient process for the accumulation of metal ions in living systems. The structure and properties of biominerals is yet to be rivaled by any synthetic effort by scientists to date. The articles in the June issue of MRS Bulletin highlight some of the challenges in characterizing and replicating the biomineralization processes and the role of non-collagenous proteins in the biomineralization process, and the talks presented in this webinar are representative examples of the research detailed in this issue.

Power Electronics with Wide Bandgap Materials


Power electronics is the branch of electronics that deals with collecting, delivering, and storing energy, by conversion and control of electrical power. While silicon has been traditionally used for power electronics, it no longer is able to keep up with the evolving requirements of higher efficiency, smaller size, and greater reliability. Enter wide bandgap materials. Researchers are now focusing on materials such as gallium nitride (GaN) and silicon carbide (SiC) to replace silicon for power electronics applications. The articles in the May issue of MRS Bulletin overview research on GaN and SiC for power electronics, and the talks presented in this webinar are representative examples of the research detailed in this issue.

Essentials of Getting Your Work Published


Whether you are a student preparing to publish your first paper, an early-career researcher hoping to polish your publishing skills, or if you just have questions about the publishing process, then this interactive "how to" session is for you. Learn the fundamentals of successful scientific publishing from MRS journal editors-in-chief. Not only are they leading researchers in their fields, but they share a dedication to high-quality content, editorial integrity and scientific scholarship. Presented in partnership with Cambridge University Press, this webinar will focus focused on:

  • How to select a journal
  • A primer of article types - research articles, review articles, letters and more
  • How to write a clear title and abstract
  • What to expect from the peer review process
  • Common pitfalls and how to avoid them

Multiscale Mechanics of Biological, Biomedical, and Biologically Inspired Materials


Mechanical property measurement protocols have their origins in metallurgy-metals being the first materials used on a broad industrial scale-as well as in mechanical and civil engineering. Recent decades have evidenced growing interest in applying these methods to biological materials or materials mimicking or replacing biological tissue. However, the mechanical properties of biological materials are highly variable and hard to determine by the traditional protocols. A more slowly emerging thought is that perhaps the mechanical theories underlying the testing protocols emanating from the metals field might not be fully applicable to highly complex, hierarchically organized biological materials and might need further development. The presentations in this webinar highlight the challenge of extending theoretical and applied mechanics to the level needed to satisfactorily and reliably determine the mechanical properties of biological and related materials.

3D Integrated Circuits: Materials Challenges


The fabrication of mobile and other electronic devices by three-dimensional integrated circuits (3D ICs) is receiving wide attention. The concept of using 3D ICs to extend the limit of Moore’s Law, by combining chip technology and packaging technology, has been explored for more than 10 years. However, we still do not mass produce 3D IC devices due to low yield and reliability, along with high cost. Most problems are caused by materials selection and integration at the small scale. The presentations in this webinar will cover some of the important aspects of materials challenges in 3D ICs, complementing the articles in the March 2015 issue of MRS Bulletin on this topic.

3D Printing of Biomaterials


Three-dimensional (3D) printing represents the direct fabrication of parts layer-by-layer, guided by digital information from a computer-aided design file without any part-specific tooling. Over the past three decades, a variety of 3D printing technologies have evolved that have transformed the idea of direct printing of parts for numerous applications. Three-dimensional printing technology offers significant advantages for biomedical devices and tissue engineering due to its ability to manufacture low-volume or one-of-a-kind parts on-demand based on patient-specific needs. However, many concerns remain for widespread applications of 3D-printed biomaterials, including regulatory issues, a sterile environment for part fabrication, and the achievement of target material properties with the desired architecture. The presentations in this webinar will cover some of the important aspects of 3D printing of biomaterials

In Situ Transmission Electron Microscopy


Transmission electron microscopy (TEM) has seen major breakthroughs over the past decade in imaging and spectroscopy at the single atomic level. Spatial resolutions have reached 0.5 Å while energy resolutions have reached 10 meV. In recent years, the focus has shifted towards in situ TEM to probe functionality of materials and to reveal how materials change dynamically under real operation conditions. Recent scientific breakthroughs using in situ TEM have largely benefited from advances in instrumentation. Advances that are specific to enable in situ capabilities include liquid or gas environmental TEM, ultrafast dynamic electron microscopy, quantitative mechanical tests, and electric and magnetic coupling. This MRS Webinar (presented by MRS Bulletin) on in situ TEM will present reviews of specific sub-areas covering the most exciting developments in the field. The talks in the webinar will provide a sampling of how in situ TEM is having a major impact on materials science today.
