Nanoscale pillars could radically improve conversion of heat to electricity

Scientists have found a creative way to radically improve thermoelectric materials, a finding that could one day lead to the development of improved solar panels, more energy-efficient cooling equipment, and even the creation of new devices that could turn the vast amounts of heat wasted at power plants into more electricity.

Engineers build cutting-edge photonic devices using standard chip-making process

The future of computing may lie not in electrons, but in photons -- in microprocessors that use light instead of electrical signals. But these photonic devices are typically built using customized methods that make them difficult and expensive to manufacture. Now, engineers have demonstrated that low power photonic devices can be fabricated using standard chip-making processes. The team dubs this a major milestone in photonic technology.
