Field-emission devices (cold cathodes) having low electron affinities can be fabricated through lattice- mismatched epitaxial growth of nitrides of elements from group III of the periodic table. Field emission of electrons from solid surfaces is typically utilized in vacuum microelectronic devices, including some...

This innovation forms a sprayable polymer film using powdered precursor materials and an in-process heating method. This device directly applies a powdered polymer onto a substrate to form an adherent, mechanically-sound, and thickness-regulated film. The process can be used to lay down both fully dense...

NASA lunar robotic science missions support the high-priority goals identified in the 2007 National Research Council report, The Scientific Context for Exploration of the Moon: Final Report (National Academies Presses, 2007). Future missions...

By condensing water from the air and soil on chilled pipes, this invention attempts to alleviate both water and food shortage problems. It offers the ability to produce agricultural crops in most hot and humid climates by watering plants with condensation from environmental...

An all-terrain, multi-role, hover-capable aircraft has a fuelefficient, rugged, vertical take-off and hover propulsion system. A raised-height, dispersal-resistant hover cushion is projected over the ground by the device as two bisected concentric streams of rotating and counter-rotating torus...

A company seeks technology that is applicable to automated assembly lines; specifically, a reliable and fast short-range wireless technology that can take the place of wired connections for robots and factory automation equipment. Equipment with appendages in motion, such as robots, is fundamentally...
