Morphing Wing Could Enable More Efficient Manufacturing and Flight

The entire shape of the wing can be changed by activating two small motors that apply a twisting pressure to each wingtip. (Photo: Kenneth Cheung/NASA) A new morphing wing architecture could greatly simplify the manufacturing process and reduce fuel consumption of aircraft by improving the wing’s aerodynamics, as well as improving its agility. The wing consists of a system of tiny, lightweight subunits that could be assembled by a team of small, specialized robots, and ultimately could be used to build the entire airframe. The wing would be covered by a “skin” made of overlapping pieces that might resemble scales or feathers.

Infrared Brings to Light Nanoscale Molecular Arrangement

Detailing the molecular makeup of materials – from solar cells to organic LEDs and transistors to medically important proteins – is not always a crystal-clear process. To understand how materials work at these microscopic scales and to better design materials to improve their function, it's necessary to know not only about their composition but also their molecular arrangement and microscopic imperfections.
