Ultra-efficient magnetic-field detector In a development that could lead to miniaturized, battery-powered devices for medical and materials imaging, contraband detection, and even geological exploration, MIT researchers have developed a new, ultrasensitive magnetic-field detector they say is 1,000 times more energy-efficient than its predecessors. Magnetic-field detectors, or magnetometers,... » read more

Leveraging error-prone chips MIT researchers reminded that as transistors get smaller, they also grow less reliable, and that while increasing the operating voltage can help, there is a corresponding increase in power consumption. As such, some researchers and hardware manufacturers are exploring the possibility of letting chips botch the occasional computation. The team has devised a system t... » read more

Thermal emitter improves solar cell efficiency Stanford University scientists have created a heat-resistant thermal emitter -- an element used in specialized solar cells -- that could significantly improve the efficiency of the cells. The heat-resistant thermal emitter is designed to convert heat from the sun into infrared light that can be absorbed by solar cells to make electricity – a tec... » read more

Untangled nanotubes Carbon nanotubes are lightweight, strong and conduct electricity, which make them ideal components in new electronics devices, such as tablet computers and touchscreen phones, but cannot be used without being separated out from their natural tangled state. Researchers from Imperial College London have developed a way to unravel and apply carbon nanotubes in the laboratory a... » read more

How light interacts with gold nanostructures With the potential to possibly increase the efficiency of solar cells and photo detectors, University of Manchester researchers have discovered that graphene can be used to investigate how light interacts with nano-antennas. The team, which also included researchers from Freie Universität Berlin and Imperial College London, have shown that graph... » read more
