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: Sensors/Data Acquisition
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: Manufacturing & Prototyping
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: Manufacturing & Prototyping
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...

Innovators at NASA's Glenn Research Center have expanded their growing portfolio of aerogels to include a new optically transparent polyimide aerogel. Aerogels — low-density, highly porous, ultralight...
Briefs: Manufacturing & Prototyping
The ability of additive manufacturing to manage small volumes, create complex designs, and fabricate lightweight but strong structures makes it a natural fit for aerospace...
Briefs: Mechanical & Fluid Systems
In biology, there are many examples where light induces movement or change — think of flowers and leaves turning toward sunlight. Magnetic elastomeric composites were developed that move in different ways...
Briefs: Electronics & Computers
A stainless steel alloy — alloy 709 — has potential for elevated-temperature applications such as nuclear reactor structures. It is exceptionally strong and resistant to damage when exposed to high...
