A faster Internet While light is capable of carrying vast amounts of information, to utilize its potential, the laser light needs to be as spectrally pure—as close to a single frequency as possible. The purer the tone, the more information it can carry. For decades researchers have been trying to develop a laser that comes as close as possible to emitting just one frequency. Today's world... » read more

Low signal loss waveguides With the potential to enable a leap ahead in size reduction and performance, DARPA-funded researchers at UCSB and CalTech have developed new methods to integrate long coils of waveguides with low signal loss onto microchips—potentially enabling a leap ahead in size reduction and performance. Long coils of optical waveguides—any structure that can guide light, ... » read more

3D Printers When thinking about 3D printers, most people probably think about creating small plastic parts or prototypes. 3D printing now can be used to print lithium-ion microbatteries the size of a grain of sand. The printed microbatteries could supply electricity to tiny devices in fields from medicine to communications, including many that have lingered on lab benches for lack of a batt... » read more

First Computer Based On Carbon Nanotubes Pointing toward a new generation of energy-efficient electronics, a team of Stanford engineers has built a basic computer using carbon nanotubes (CNT), a semiconductor material that has the potential to launch a new generation of electronic devices that run faster, while using less energy, than those made from silicon chips. People have been talking ... » read more

By Ed Sperling It’s not the “God particle” or anything even remotely connected to the formation of the universe. But in particle physics, the powerful forces that keep the tiny particles in an atom confined to a very small space are now coming into much better focus.

Graphene-based device enables next-gen energy storage Monash University researchers have brought next generation energy storage closer with an engineering first: a graphene-based device that is compact, yet lasts as long as a conventional battery. A research team in the Department of Materials Engineering has developed a completely new strategy to engineer graphene-based supercapacitors (SC... » read more
