Topological transitions in metamaterials

The ability to control the flow of electrons using engineered materials is fundamental to the information technology revolution, yet many properties of matter are still unclear. Now a University of Alberta researcher is closer to understanding some of the exotic electronic properties in matter using optical analogues.

Nanotechnology cuts water use, energy costs

As part of a larger consortium involving partners from several energy companies, universities, and government agencies, researchers at the U.S. Department of Energy's Argonne National Laboratory are developing a special class of nanoparticles that partially melt as steam evaporates from a plant's cooling towers, absorbing a significant percentage of the diffused heat in the system.

New frontier: Chips transfer data at light speed

The computer industry is nearing a crisis: microchips get smaller and faster but they struggle to transfer data at sufficient speeds. Electrons flowing through standard chip connections are just too slow. Now EU-funded researchers have shown how chips with built-in lasers which use multiple wavelengths of light could in the future transmit data at terabit speeds.

Probing the history of nanotechnology

Scanning probe microscopes feature prominently in the history of nanotechnology but, as a recent book on the subject makes clear, this history could have been very different.

How to turn a living snail into a power source

The world's first "electrified snail" has joined the menagerie of cockroaches, rats, rabbits and other animals previously implanted with biofuel cells that generate electricity - perhaps for future spy cameras, eavesdropping microphones and other electronics - from natural sugar in their bodies.
