2-Faced 2-D Material is a First at Rice

From Rice University, August 14, 2017, by Mike Williams:
 
"The Rice laboratory of materials scientist Jun Lou has made a semiconducting transition-metal dichalcogenide (TMD) that starts as a monolayer of molybdenum diselenide. They then strip the top layer of the lattice and replace precisely half the selenium atoms with sulfur. The new material they call Janus sulfur molybdenum selenium (SMoSe) has a crystalline construction the researchers said can host an intrinsic electric field and that also shows promise for catalytic production of hydrogen. Tight control of the conditions in a typical chemical vapor deposition furnace - 800 degrees Celsius (1,872 degrees Fahrenheit) at atmospheric pressure - allowed the sulfur to interact with only the top layer of selenium atoms and leave the bottom untouched.

Fast and Sensitive Mid-IR Detectors for Gas Sensing

From EuroPhotonics, June 2017, by Adam Piotrowski (Vigo Systems, S.A., Poland):
 
" Mid-IR gas-sensing applications are currently some of the fastest-growing markets for sensors, driven by social needs for better quality of life, geopolitical situations and recent technological advances such as fast, uncooled detectors, new tunable sources and mid-IR optics. And the need is growing. Traditionally, these detectors have been grown by liquid phase epitaxy. The present development of high-operating-temperature IR photodetectors has been dominated by complex bandgap heterostructures grown by low-pressure and flexible technologies such as molecular beam epitaxy (MBE) or metalorganic chemical vapor deposition (MOCVD).

Breathable, Wearable Electronics on Skin for Long-Term Health Monitoring

From EurekAlert!, July 17, 2017 by the University of Tokyo:

"A hypoallergenic electronic sensor can be worn on the skin continuously for a week without discomfort, and is so light and thin that users forget they even have it on, says a Japanese group of scientists. The scientists at the University of Tokyo's Graduate School of Engineering have developed an electrode constructed from nanoscale meshes containing a water-soluble polymer, polyvinyl alcohol (PVA), and a gold layer -- materials considered safe and biologically compatible with the body. The device can be applied by spraying a tiny amount of water, which dissolves the PVA nanofibers and allows it to stick easily to the skin--it conformed seamlessly to curvilinear surfaces of human skin."

NASA Team Takes on a New Optical Challenge

From NASA, May 30, 2017 by Lori Keesey (NASA Goddard Space Flight Center):
 
" Optical experts at NASA's Goddard Space Flight Center in Greenbelt, Maryland, are investigating techniques for creating highly reflective aluminum mirrors sensitive to the infrared, optical, and far-ultraviolet wavelength bands - a broad spectral range envisioned for proposed space telescopes after the James Webb Space Telescope and Wide Field Infrared Survey Telescope. These proposed missions would tackle a broad range of astrophysics studies, from the epoch of reionization, through galaxy formation and evolution, to star and planet formation. Unfortunately, no one has developed a coating that effectively protects and maintains a mirror's high reflectivity in the 90- to 130-nanometer range, also known as the Lyman Alpha range. The team specifically is studying three different techniques and materials for creating and applying protective coatings on aluminum mirrors to prevent them from oxidizing when exposed to oxygen and losing their reflectivity. Under one coating approach, the team would use physical vapor deposition to apply a thin layer of xenon difluoride gas to an aluminum sample. They are also investigating the use of ion-assisted physical vapor deposition and atomic layer deposition to apply thin films of aluminum trifluoride. "   READ FULL ARTICLE.

Self-Powered System Makes Smart Windows Smarter 

From Princeton University, June 30, 2017, by Sharon Adarlo:
 
" Researchers at Princeton University have developed a different type of smart window: a self-powered version that promises to be inexpensive and easy to apply to existing windows. This system features solar cells that selectively absorb near-ultraviolet (near-UV) light, so the new windows are completely self-powered. Researchers described how they used organic semiconductors - contorted hexabenzocoronene (cHBC) derivatives - for constructing the solar cells. To construct the solar cell, the semiconductor molecules are deposited as thin films on glass with the same production methods used by organic light-emitting diode manufacturers.

Critical Materials Institute Manufactures Magnets Entirely from U.S.-Sourced Rare Earths

From Ames Laboratory, July 28, 2017:

" The Critical Materials Institute, a U.S. Department of Energy Innovation Hub, has fabricated magnets made entirely of domestically sourced and refined rare-earth metals. They are typical by the standard of NdFeB magnets. The process used to make them is based on the techniques used elsewhere, albeit with some significant advances in a couple of crucial steps. But in the global rare-earth metals market, the provenance is extraordinary -- U.S.-mined ores, domestically processed, and domestically manufactured into magnets. And that's important, because rare-earth magnets are used in a wide and ever-increasing number of modern technologies, and the ability to produce them domestically could have broad positive impact on national economy and security.

System for Repairing Cracks in Structures

From Tech Briefs, July 1, 2017 by Langley Research Center (Hampton, VA):

" NASA's Langley Research Center has developed an innovative coating to heal cracks in metal components, such as in aircraft and bridges. A metal structure is coated with a low-temperature healing agent and when a crack is produced under cyclic load, it is then subjected to an external heat source (to heat the healing film to 250 °F - 300 °F). The component is processed in a vacuum. The coating has been prototyped on a titanium alloy sheet with an indium-tin eutectic alloy coating. Development is ongoing to produce a coating that does not require a vacuum and utilizes an integrated heat source." READ FULL ARTICLE.

Brookhaven Lab Reaches Major Milestone for Large Synoptic Survey Telescope Project

From Brookhaven National Laboratory, June 26, 2017:

" Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have completed the first "science raft" for the Large Synoptic Survey Telescope (LSST), a massive telescope designed to capture images of the universe like never before. The raft is part of the sensor array that will make up the crucial camera segment of the telescope, and its completion is the first major milestone for Brookhaven's role in the project. Now under construction on a mountaintop in Chile, LSST will capture an image of the entire sky in the southern hemisphere every three nights, allowing researchers to create a time-lapse movie of the universe. The 3,200 megapixel sensor array being developed at Brookhaven is what will enable LSST to capture this extraordinary view when it begins operations in 2023. " READ FULL ARTICLE.

Thin Film Encapsulation of Moisture-Sensitive Flexible Electronics




From the Organic and Printed Electronics (OPE) Journal, July 
2017, by Mark Steltenpool and Luca Gautero (Meyer Burger):
 
" High throughput manufacturing of thin film moisture barriers is key for the marketability of moisture-sensitive flexible electronics. Meyer Burger (MBNL) has developed both sheet-to-sheet (S2S) and roll-to-roll (R2R) equipment for the fabrication of TFE. Inorganic thin film deposition and organic layer coating are combined into single, fully automated cluster tools with industrial manufacturing capabilities. Two solutions are compared by MBNL which differ by the deposition technique of the inorganic layer: either (spatial) atomic layer deposition (sALD) or plasma enhanced chemical vapor deposition (PECVD).  Sheet-to-sheet (S2S) or roll-to-roll (R2R) are common equipment implementations.

Precision Work: Defect-Free Coatings for Silicon Spheres

From Fraunhofer Institute for Surface Engineering and Thin Films (IST), July 4, 2017:
 
" The prototype kilogram - to which all scales are calibrated to - is losing weight. International efforts are striving to redefine the base unit for measuring mass and, in future, redefine the kilogram on natural constants. For this purpose, the Avogadro experiment determines the number of atoms in almost perfect silicon spheres. Fraunhofer researchers have recently succeeded in homogeneously coating the spherical surfaces - the measurement uncertainty can be limited to a range below 10 micrograms. For the coating, the researchers at the IST selected the Atomic Layer Deposition (ALD). The coatings of the silicon sphere have been concluded and now the measurements are being performed at the Physikalisch-Technische Bundesanstalt (PTB) (the national metrology institute of Germany). The results will be available this summer and will then be presented at the Conference on Weights and Measures in autumn 2018. READ FULL ARTICLE.
