Technologies using stretchable materials are increasingly important. Yet, in general, it is not possible to control how they stretch with much more sophistication than inflating balloons. A method was developed that allows the calculated transformation of 2D stretchable surfaces into targeted 3D shapes.

A real-time instrument was developed that could scan the atmosphere for toxic agents in order to alert communities to a biological or chemical attack.

Hazardous airborne particles pose a risk for health and safety in a variety of environments; thus, detection of these small particles is essential. Current particle magnification systems are bulky and require a lot of power for operation, making them unsuitable to easily detect and analyze...

This novel innovation from Ames Research Center allows spacecraft to share rides with larger spacecraft that are headed to Geosynchronous Earth Orbit (GEO). The secondary spacecraft is dropped off Geosynchronous Transfer Orbit (GTO) at any time during the day or...

The use of multifunctional composites such as mechanically reinforced, electrically and thermally conductive parts is of interest in a range of application areas. Especially interesting and important is where tailorability of function is achieved by strategic placement of materials with...

Oxygen adversely impacts food flavor and nutrition. NASA’s proposed five-year shelf life for astronaut food requires aggressive measures to minimize oxygen. Previously, NASA packaged foods in containers with a high oxygen and moisture barrier. These materials have limiting properties. They contain a...

A fabric was developed that converts kinetic energy into electric power. The greater the load applied to the textile and the wetter it becomes, the more electricity it generates. The woven fabric generates electricity when it is stretched or exposed to pressure. The fabric can currently generate...

While silicon carbide (SiC) is an ideal material for building ultraviolet (UV) photodetectors, the absorbed photons get recombined in the first few nanometers at the surface due to a large absorption coefficient in the 200- to 250-nm wavelength band....

NASA Langley Research Center has developed an innovative radiation shield made by layering metal materials in the Z-shielding method. It is a new, low-cost, and easy-to-implement method to protect CubeSat electronic circuits from ionizing radiation found in low...

Newly developed two-dimensional (2D) materials such as graphene — which consists of a single layer of carbon atoms — have the potential to replace traditional microprocessing chips based on silicon, which have reached the limit of how small they can get. But engineers have been...

Plastics are excellent insulators, meaning they can efficiently trap heat — a quality that can be an advantage in something like a coffee cup sleeve. But this insulating property is less desirable in products such as plastic casings for laptops and mobile phones that overheat, in part, because the...

Many aircraft need to operate efficiently at more than one flight regime; for example, certain airframes are expected to perform in relatively high-speed cruise modes, as well as slower loitering scenarios. Unfortunately, an engine operates most efficiently when the exit velocity closely matches the speed of the...

Innovators at NASA’s Glenn Research Center have made several breakthroughs in treating hexagonal boron nitride (hBN) nanomaterials, improving their properties to supplant carbon nanotubes in many applications. These inventors have greatly enhanced the processes of intercalation and exfoliation....

If you think there’s too much hype surrounding 3D printing, perhaps that’s because you’re only thinking about plastic parts.

Does less nitrogen oxide mean more particulate emissions? A reader asks our expert.

A Tech Briefs TV video this week featured AlterEgo, a “mind-reading” wearable headset from MIT's Media Lab.The technology allows a user to silently converse with a computing device, AI assistant, or application without any audible voice or discernible movements. The wearable device captures electrical...

Researchers from the University of Buffalo found a counter-intuitive way of improving the water-purification process: keeping things cool.

A new system from the Georgia Institute of Technology has a sound approach to recognizing tiny gestures of the hand.

What parts of the design process are the most difficult? What information are you looking for now to help you with your job? Is there a specific technology area that can be challenging to find out the latest solutions for?

Can metal 3D printing help automakers with more than just prototyping? It can, and it has, says our engineering expert.
