Brain sensors and electronic tags that dissolve. Boosting the potential of renewable energy sources. These are examples of the latest research from two pioneering researchers selected as this year’s Kavli lecturers at the 247th National Meeting & Exposition of the American Chemical Society (ACS), the world’s largest scientific society. The meeting features more than 10,000 […]

Tiny Switches Could Support Next-Generation Wireless Networks
Researchers working in GE labs have developed tiny electrical switches thinner than a human hair that can transmit kilowatts of power. They are called micro-electro-mechanical systems, or MEMS. The technology’s DNA is built around industrial applications, and MEMS could help reduce waste heat and power consumption in medical devices, aviation systems and other GE products. […]
Innovative computer under scrutiny
D-Wave – a special computing machine with this name has been getting computer scientists and physicists talking for a number of years now. The Canadian technology company of the same name is advertising the machine as a quantum computer. However, whether or not the machine does in fact use quantum effects is the subject of […]

The UltiMod and Xgen families meet the required Voltage Sag Immunity of 200 ms at 50 percent Voltage Sag as well […]
Potentially safer, greener alternative to BPA could come from papermaking waste
A waste product from making paper could yield a safer, greener alternative to the potentially harmful chemical BPA, now banned from baby bottles but still used in many plastics. Scientists made the BPA alternative from lignin, the compound that gives wood its strength, and they say it could be ready for the market within five […]
Bionic Plants as Supercharged Energy Producers
Plants have many valuable functions: They provide food and fuel, release the oxygen that we breathe, and add beauty to our surroundings. Now, a team of MIT researchers wants to make plants even more useful by augmenting them with nanomaterials that could enhance their energy production and give them completely new functions, such as monitoring […]

A battery that ‘breathes’ could power next-gen electric vehicles
Sales of electric vehicles (EVs) nearly doubled in 2013, but most won’t take you farther than 100 miles on one charge. To boost their range toward a tantalizing 300 miles or more, researchers are reporting new progress on a “breathing” battery that has the potential to one day replace the lithium-ion technology of today’s EVs. […]
PMICs present high efficiency and low standby power consumption for AC/DC power supplies
