Clean energy future: New cheap and efficient electrode for splitting water

UNSW Australia scientists have developed a highly efficient oxygen-producing electrode for splitting water that has the potential to be scaled up for industrial production of the clean energy fuel, hydrogen. The new technology is based on an inexpensive, specially coated foam material that lets the bubbles of oxygen escape quickly.

Data structures influence speed of quantum search in unexpected ways: Highly connected structures don't always support fastest quantum computing

Using the quantum property of superposition, quantum computers will be able to find target items within large piles of data far faster than conventional computers ever could. But the speed of the search will likely depend on the structure of the data.

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.
