Quantum dots or nanowires for solar?

A trio of researchers at North Dakota State University and the University of South Dakota have turned to computer modeling to help decide which of two competing materials should get its day in the sun as the nanoscale energy-harvesting technology of future solar panels -- quantum dots or nanowires.

Guided growth of nanowires leads to self-integrated circuits

Researchers working with tiny components in nanoelectronics face a challenge similar to that of parents of small children: teaching them to manage on their own. The nano-components are so small that arranging them with external tools is impossible. The only solution is to create conditions in which they can be “trusted” to assemble themselves.

Plasmonics used to create cloaking device

Stanford University engineers have created a device that can detect light while itself remaining invisible.

'Nanoforest' turns water to hydrogen fuel

University of California, San Diego electrical engineers are building a forest of tiny nanowire trees in order to capture solar energy and harvest it for hydrogen fuel generation.

Tiny wires fill missing link in nanoscale computing

Wires just one atom tall and four atoms wide have been shown to have the same current-carrying capability as copper wires, giving a new lease of life to Moore's Law.

'3D' transistors promise faster circuits and lighter laptops

A new type of transistor based on a 3D structure could replace silicon chips, say researchers from Purdue and Harvard universities.

Copper nanowires could lower touch screen costs

Using films made of copper nanowires could cut the cost of touch screens, LEDs and solar cells, while allowing the development of foldable electronics and improved solar cells, according to new research.

Microbes turn nuclear waste into electricity

Researchers at Michigan State University have developed a new strain of a microbe which can efficiently clean up nuclear waste and other toxic metals while generating electricity.

Nanowire opens door to new devices

A dual-headed research team has completed an interesting act of nanoscale engineering. It is the first nanowire of its kind.

Programmable nanoprocessor created

Harvard University scientists and the Mitre Corporation have  demonstrated the world's first programmable nanoprocessor.

Bacteria may communicate through nanowires

Some bacteria grow electrical hair that lets them link up in big biological circuits, possibly communicating and sharing energy.

Copper nanowires promise cheap, flexible screens

Imagine a foldable iPad: it's perfectly possible, say Duke University scientists, who have found a simple way to make tiny copper nanowires in quantity.
