A self-correcting crystal may unleash the next generation of advanced communications

Researchers from the National Institute of Standards and Technology (NIST) have joined with an international team to engineer and measure a potentially important new class of nanostructured materials for microwave and advanced communication devices. Based on NIST's measurements, the new materials - a family of multilayered crystalline sandwiches - might enable a whole new class of compact, high-performance, high-efficiency components for devices such as cellular phones.

Understanding what makes a thin film solar cell efficient

Scientists have developed a new technique for manufacturing high-efficiency, flexible, thin film solar cells from CIGS (copper indium gallium di-selenide) semiconductors. This has enabled them to achieve an efficiency of 20.4 percent for the conversion of sunlight into electrical energy. As the solar cells are deposited onto plastic foils, they could be produced on an industrial scale using cost-effective roll-to-roll manufacturing.

Diamond imperfections pave the way to technology gold

From supersensitive detections of magnetic fields to quantum information processing, the key to a number of highly promising advanced technologies may lie in one of the most common defects in diamonds. Researchers at the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have taken an important step towards unlocking this key with the first ever detailed look at critical ultrafast processes in these diamond defects.
