A research team at the University of Illinois Urbana-Champaign has found a way to stop concrete rail ties from cracking under heavy train traffic. Led by civil and environmental engineering professor ...

When speaking of electric aircraft, one of the most talked about benefits is a reduced noise level, compared to standard airplanes. But there’s still a long way to go until electric air mobility ...

Abstract: The return of commercial supersonic flight requires innovative solutions to be developed that meet noise and efficiency requirements for overland flight. To study such a possibility NASA is ...

NASA engineers have added a new twist to a cutting edge aerospace technology by demonstrating how a new Shape Memory Alloy (SMA) actuator can fold a 300-lb (136 kg) wing section from an F/A-18 Hornet ...

Laser powder bed fusion, a 3D-printing technique, offers potential in the manufacturing industry, particularly when fabricating nickel-titanium shape memory alloys with complex geometries. Although ...

As air traffic is projected to increase dramatically over the next decade, reducing noise pollution becomes an even more necessary and demanding challenge. Decades of research have been dedicated to ...

Shape Memory Alloys (SMAs) are unique materials that exhibit shape memory behavior, which is exemplified by the ability recover large deformations due to changes in external loading conditions, ...

Scientists captured live action details of the phase transitions of shape memory alloys, giving them a better idea how to improve their properties for applications. Known to many as muscle wire or ...

Having a home near a busy airport certainly has its perks. It is close to many establishments and alleviates the problem of wading through endless traffic to catch flights. But it does come at a cost ...
