Carbon nanotubes (CNTs) can be grown in dense lithographically patterned forests to form framework structures that can be filled in via chemical vapor deposition to form solid structures. These solid structures can then be used in microelectromechanical systems (MEMS) applications. Initial testing with these structures suggests that when these frameworks are filled with carbon, the resulting material...
Air filled salvage lift bags have been a problem and danger since their invention due to uncontrolled vertical acceleration as they ascend the water column. This paper presents the design of an automated purge valve to control a lift bag's ascent. The automated purge valve monitors the changes in pressure to determine the ascent velocity of the lift bag. The resulting velocity is then evaluated by...
