Nano piano's lullaby could mean storage breakthrough

Researchers from the University of Illinois at Urbana-Champaign have demonstrated the first-ever recording of optically encoded audio onto a non-magnetic plasmonic nanostructure, opening the door to multiple uses in informational processing and archival storage.

New technology may double radio frequency data capacity: Columbia engineers invent nanoscale IC that enables simultaneous transmission and reception at the same frequency in a wireless radio

A team of Columbia Engineering researchers has invented a technology--full-duplex radio integrated circuits (ICs)--that can be implemented in nanoscale CMOS to enable simultaneous transmission and reception at the same frequency in a wireless radio. Up to now, this has been thought to be impossible: transmitters and receivers either work at different times or at the same time but at different frequencies. The Columbia team, led by Electrical Engineering Associate Professor Harish Krishnaswamy, is the first to demonstrate an IC that can accomplish this. The researchers presented their work at the International Solid-State Circuits Conference (ISSCC) in San Francisco on February 25.

Silver implant nanotech killing infections: NC State Industrial & Systems Engineering Research Team Arms Implants With Battery-Activated Nanotechnology

As the number of joint replacement surgeries in the U.S. grows, so are concerns about the complications of infection from antibiotic-resistant "superbugs." Biomedical engineers at NC State University are fighting back by developing nanotechnology built directly into orthopedic implants using a battery-activated device to power an army of microscopic germ-killers. Even antibiotic-resistant bacteria such as MRSA are on the hit list.
