In contrast, the composite-treated hair bundle recovered around 10% of its shape and maintained it. To the best of the researchers’ knowledge, this is the first study to evaluate the application of ...

With 4D printing, the objects can change shape or properties using external stimuli such as temperature, light, pH, magnetic field, electricity, and moisture. Additionally, the changes in shape or ...

Shape-memory metals, which can revert from one shape to a different one simply by being warmed or otherwise triggered, have been useful in a variety of applications, as actuators that can control the ...

Although an airliner's engines may be quite loud on takeoff, its wings also create a lot of wind noise when it's landing. According to a new study, the latter problem could be addressed with the ...

The secret to how steel hardens and shape-memory alloys snap into place lies in rapid, atomic-scale shifts that scientists have struggled to observe in materials. Now, Cornell researchers are ...

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 ...

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 ...
