National Hispanic science and engineering organization honors two Sandia researchers
Materials scientist Nic Argibay and health and safety senior manager Rafael Gonzalez were honored for leadership and achievement in science, technology, engineering and math.
Investigating Materials that Can Go the Distance in Fusion Reactors
Future fusion reactors will require materials that can withstand extreme operating conditions, including being bombarded by high-energy neutrons at high temperatures. Scientists recently irradiated titanium diboride (TiB2) in the High Flux Isotope Reactor (HFIR) to better understand the effects of fusion neutrons on performance.
Markus J. Buehler, McAfee Professor of Engineering, Massachusetts Institute of Technology (MIT), joins MRS Bulletin as new Editor focused on Original Research
MRS Bulletin is pleased to announce the appointment of Markus J. Buehler, McAfee Professor of Engineering at the Massachusetts Institute of Technology (MIT), as editor of the new MRS Bulletin Impact section. In this new position, Buehler will partner with MRS Bulletin Editor Gopal R. Rao and his team to launch and develop an important new section of the journal focused on publishing high-impact original research articles, complemented by review articles and a strong set of editorial content. His tenure begins October 1.
Even Hard Materials Have Soft Spots
The Achilles Heel of “metallic glasses” is that while they are strong materials—even stronger than conventional steels—they are also very brittle. The initial failures tend to be localized and catastrophic. This is due to their random amorphous (versus ordered crystalline) atomic structure. Computer simulations revealed that the structure is not completely random, however, and that there are some regions in the structure that are relatively weak. Defects nucleate more easily in these regions, which can lead to failure. This understanding of the mechanical properties has led to a strategy for making the material stronger and less brittle.
Research Shows That Doing the Twist is Hot, Unwinding is Cool
An international team led by researchers at The University of Texas at Dallas and Nankai University in China has discovered a new technology for refrigeration that is based on twisting and untwisting fibers.
ORNL, University of Toledo to collaborate on advanced materials, manufacturing research for vehicle applications
The U.S. Department of Energy’s Oak Ridge National Laboratory and The University of Toledo have entered into a memorandum of understanding for collaborative research into the advanced design and manufacturing of high-strength, intelligent, lightweight materials for use by the automotive sector.
The Materials Research Society Congratulates John B. Goodenough, M. Stanley Whittingham and Akira Yoshino on Receiving the Nobel Prize in Chemistry 2019
According to the official Nobel announcement, “The Nobel Prize in Chemistry 2019 rewards the development of the lithium-ion battery. This lightweight, rechargeable and powerful battery is now used in everything from mobile phones to laptops and electric vehicles. It can also store significant amounts of energy from solar and wind power, making possible a fossil fuel-free society.”
Cracking in Harsh Environments Needs Stress and Corrosion, But Not at the Same Time
Alloys (metals combining two or more metallic elements) are typically stronger and less susceptible to cracking than pure metals. Yet when alloys are subjected to stress and a harsh chemical environment, the alloy can fail. The reason? Cracks caused by corrosion.
Simultaneous Clean and Repair
Scientists have developed a novel and efficient approach to surface cleaning, materials transport, and repair.
First report of superconductivity in a nickel oxide material
Scientists at SLAC and Stanford have made the first nickel oxide material that shows clear signs of superconductivity – the ability to transmit electrical current with no loss. The first in a potential new family of unconventional superconductors, its similarity to the cuprates raises hopes that it can be made to superconduct at relatively high temperatures.
Knowledgebase is power for nuclear reactor developers
Six new nuclear reactor technologies are planned to commercially deploy between 2030 and 2040. ORNL’s Weiju Ren heads a project managing structural materials information. This conversation explores challenges and opportunities in sharing nuclear materials knowledge internationally.
Scientists can now control thermal profiles at the nanoscale
Scientists have tested an experimental system that uses a near-infrared laser to actively heat two gold nanorod antennae to different temperatures. The nanorods are electromagnetically and thermally coupled, yet the team measured reversible temperature differences of up to 20 degrees Celsius.
Cultivating the Assembly Landscape
For the first time, a team determined and predictably manipulated the energy landscape of a material assembled from proteins. Designing materials that easily and reliably morph on command could benefit water filtration, sensing applications, and adaptive devices.
Self healing robots that “feel pain”
Over the next three years, researchers from the Vrije Universiteit Brussel, University of Cambridge, École Supérieure de Physique et de Chimie Industrielles de la ville de Paris (ESPCI-Paris) and Empa will be working together with the Dutch Polymer manufacturer SupraPolix on the next generation of robots: (soft) robots that ‘feel pain’ and heal themselves. The partners can count on 3 million Euro in support from the European Commission.
Neutrons shed light on industrial catalyst for hydrogen production
Collaborators at the Department of Energy’s Oak Ridge National Laboratory and U.S. universities used neutron scattering and other advanced characterization techniques to study how a prominent catalyst enables the “water-gas shift” reaction to purify and generate hydrogen at industrial scale.
