Position sensors: magnets know their place

Non-contact position sensors are small but important parts of many modern machines. Researchers have used a phenomenon known as magnetoresistance to develop a practical, low-cost position sensor that performs better than existing designs. Commercial production will follow this year.

Special coating greatly improves solar cell performance

The energy from sunlight falling on only 9 percent of California's Mojave Desert could power all of the United States’ electricity needs if the energy could be efficiently harvested, according to some estimates. Unfortunately, current-generation solar cell technologies are too expensive and inefficient for wide-scale commercial applications. A team of Northwestern University researchers has developed a new anode coating strategy that significantly enhances the efficiency of solar energy power conversion.

Seashells inspire space age material

The next generation of aeroplanes and spacecraft could be made from materials inspired by seashells and pearls, according to researchers in Switzerland. By mimicking the structure of nacre, better known as mother of pearl, the scientists believe they can create strong and flexible components that are perfect for advanced aerospace applications.

IBM scientists first to measure force required to move individual atoms

IBM scientists, in collaboration with the University of Regensburg in Germany, are the first ever to measure the force it takes to move individual atoms on a surface. This fundamental measurement provides important information for designing future atomic-scale devices: computer chips, miniaturized storage devices, and more.
