Researchers demonstrated the controlled vertical manipulation of a single hydrogen (H) atom using the tip of an atomic force microscope sensor and its application in characterizing and engineering silicon dangling bond-based structures of relevance to nanoelectronic devices.
Based on battery technology and made from layers of black phosphorus that are only a few atoms thick, the new device generates small amounts of electricity when it is bent or pressed even at the extremely low frequencies characteristic of human motion.
The U.S. Department of Agriculture's (USDA) National Institute of Food and Agriculture (NIFA) announced 13 grants totaling $4.6 million for research on the next generation of agricultural technologies and systems to meet the growing demand for food, fuel, and fiber.
Researchers have developed an optical imaging tool to visualize surface chemistry in real time. They imaged the interfacial chemistry in the microscopically confined geometry of a simple glass micro-capillary.
