Menlo Park, Calif. --Scientists have turned the smallest possible bits of diamond and other super-hard specks into "molecular anvils" that squeeze and twist molecules until chemical bonds break and atoms exchange electrons. These are the first such chemical reactions triggered by mechanical pressure alone, and researchers say the method offers a new way to do chemistry at the molecular level that is greener, more efficient and much more precise.
Berkeley Lab mathematicians have developed a new approach to machine learning aimed at experimental imaging data. Rather than relying on the tens or hundreds of thousands of images used by typical machine learning methods, this new approach "learns" much more quickly and requires far fewer images.

Organic polymer solar cells show potential to provide solar power to remote microwatt sensors, wearable technology and the Wi-Fi-connected appliances constituting the "internet of things." While PSCs cannot match the durability or efficiency of inorganic solar cells, the potential to mass-produce nontoxic, disposable solar panels using roll-to-roll production makes them attractive for additional applications. In this week's Journal of Renewable and Sustainable Energy, researchers review the latest advances and remaining challenges in PSC technology.
