The General Dynamics Bluefin SandShark is a small (~4 ft), open-platform, autonomous underwater vehicle (AUV). It combines a standardized low-cost tail with core vehicle systems, a large modular payload area, and an open development platform.
Chemistry usually involves precise measurements and careful testing in order to get significant results. But a bunch of notable discoveries happened by accident. In
The National Science Foundation (NSF), Arlington, Va., announced $24 million in funding to support a new science and technology center at the University of Colorado Boulder, expanding the university’s role as a national leader in imaging, materials, nano, bio, and energy sciences.
Scientists developed a smart crystal that can heal itself after breaking without any chemical or biological intervention. The crystal relies on its own molecular structure and physical contact to heal—similar to cuts on skin.
A new technology developed by Pennsylvania State University researchers, called cold sintering process (CSP), has opened a window on the ability to combine incompatible materials, such as ceramics and plastics, into new, useful compound materials, and to lower the energy cost of many types of manufacturing.
