A graphene sheet stretched among three electrodes is the tiniest device to directly receive radio signals, researchers say. Nanoscale radio receivers could be useful for sensing, physics studies and radio signal processing, which could even make them useful for mobile phones.
Researchers at Rensselaer Polytechnic Institute have turned a sheet of nano-thin gold into what could be the next big advance in infrared technology. Taking advantage of the unique properties of gold at the nanoscale, scientists there have created a "microlens" system that could boost detectivity in quantum-dot-based IR detectors by 20 times.
IBM scientists working across three countries have created the smallest-ever 3D map of the world -- so tiny that 1,000 maps could fit on a grain of salt.
The map, measuring 22 by 11 micrometers, is scratched out on a polymer surface. Every 8 nanometers corresponds to 1,000 meters of altitude -- so Mount Everest would be about 64 nanometers high.
Meet PopSci's annual Brilliant 10--a selection of the brightest young researchers in the country. They're helping to keep us healthy, prevent disasters, and make green energy cheaper than coal. Lucky for us, our future is in their capable hands
We have a credo around here: The future will be better. It may sound optimistic in light of our wheezing environment and limping economy, but then you haven't met the Brilliant 10, PopSci's annual selection of the nation's most promising young researchers.
