Tiny Graphene Radios May Lead to Internet of Nano-Things

This image shows graphene-based nanoantennas (blue and red dots) on a chip. (Credit: University at Buffalo) For wireless communication, we’re all stuck on the same traffic-clogged highway — it’s a section of the electromagnetic spectrum known as radio waves. Advancements have made the highway more efficient, but bandwidth issues persist as wireless devices proliferate and the demand for data grows. The solution may be a nearby, mostly untapped area of the electromagnetic spectrum known as the terahertz band.

Novel Computer Chips Could Bridge Gap Between Computation and Storage

Software written by Jing Li, right, and her students — including Jialiang Zhang, left —allows programmers to directly use existing coding languages with the new Liquid Silicon chips. (Credit: Stephanie Precourt/UW–Madison College of Engineering) Computer chips in development at the University of Wisconsin–Madison could make future computers more efficient and powerful by combining tasks usually kept separate by design. Jing Li, an assistant professor of electrical and computer engineering at UW–Madison, is creating computer chips that can be configured to perform complex calculations and store massive amounts of information within the same integrated unit — and communicate efficiently with other chips. She calls them “liquid silicon.”

Yoon, Korea University) A new, ultrathin film that is both transparent and highly conductive to electric current has been produced by a cheap and simple method devised by an international team of nanomaterials researchers from the University of Illinois at Chicago and Korea University. The film is also bendable and stretchable, offering potential applications in roll-up touchscreen displays, wearable electronics, flexible solar cells and electronic skin.

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.
