Single-Crystal SiGe/Sapphire Epitaxy
NASA's Langley Research Center has developed a new low-temperature method of SiGe/sapphire growth that produces the same single-crystal films with much less thermal loading effort to the substrate. This eliminates the time-consuming and costly high heating, long thermal soak times, and interfacial Si layer....
Briefs: Energy
From airplane wings, to overhead power lines, to the giant blades of wind turbines, a buildup of ice can cause problems ranging from impaired performance all the way to catastrophic...

Scientists from the Center for Functional Nanomaterials (CFN) — a U.S. Department of Energy (DOE) Office of Science User Facility at Brookhaven National Laboratory — have dramatically improved...
Briefs: Electronics & Computers
3D printing allows for the efficient manufacture of complex geometries. A very promising method is direct laser writing in which a computer-controlled focused laser beam acts as a pen and produces the desired...
Briefs: Sensors/Data Acquisition
Painting of surfaces having numerous facets and/or curved surfaces is a time-consuming process that requires the application of several coats (layers) of paint. Such surfaces are often found on...
Briefs: Test & Measurement
Automated Fiber Placement (AFP) machines can be susceptible to tow-tape defects such as gaps and overlaps. These can reduce strength between 7% and 32%....
Briefs: Photonics/Optics
Egyptian blue, derived from calcium copper silicate, was routinely used on ancient depictions of gods and royalty. Previous studies have shown that when Egyptian blue absorbs visible light, it then...
Briefs: Aerospace
NASA's Glenn Research Center developed a novel means of articulating the outboard portion of an aircraft wing to create the optimal geometry for given flight conditions. The Spanwise Adaptive Wing (SAW) concept employs a...
Briefs: Mechanical & Fluid Systems
Infrared motion detectors can cover only a limited amount of space, a person has to be within the detector's line of sight to be detected, and lights can go off when a person remains still...
Briefs: Mechanical & Fluid Systems
For many highly stressed engineering applications like bearings and gears, contaminated steel parts can lead to devastating outcomes such as an emergency shutdown or the end of a mission. Ensuring that these critical...
Briefs: Medical
A controllable material was developed that can transform into complex, pre-programmed shapes via light and temperature stimuli, allowing it to morph into a different shape before fully...
