    摘要: Carbon nanotube (CNT) films, patterns and biochips and methods of making the same are provided. Such a biochip comprises a bio-receptor attached by means of an exposed chemical functional group on a surface of a high density CNT film or pattern produced by repeated lamination of CNTs on a substrate with exposed amine groups. Various types of CNT-biochips may be fabricated by bonding of bio-receptors to a CNT pattern (or film) containing exposed carboxyl groups or modified by various chemical functional groups. Further, the CNT-biochip may be used to measure an electrical or electrochemical signal using both conductor and semiconductor properties of the CNT, thereby not needing labeling. Upon fluorescent measurement of DNA hybridization using such a CNT-DNA chip it is possible to show more distinct signals useful for genotyping, mutation detection, pathogen identification and the like.

    摘要: A system for producing variable amplitude pneumatic pulses, such as may be used to prevent flow separation on airfoil and diffuser surfaces to control stalling, utilizes a source of pressurized air which is regulated and fed to parallel outlet lines. Each outlet line has a control valve therein attached to a controller for activation of the valves. The first parallel line leads to an actuator which supplies the pulsed air to a desired surface. The second parallel line leads to the atmosphere. By cycling the valves at about ninety degrees out of phase, pneumatic pulses of large amplitude are obtained with a simple device capable of being transported on the aircraft.
