20090317233 | ROTARY NANOTUBE BEARING STRUCTURE AND METHODS FOR MANUFACTURING AND USING THE SAME - In one embodiment, a rotary device includes a multiwall nanotube that extends substantially perpendicularly from a substrate. A rotor may be coupled to an outer wall of the multiwall nanotube, be spaced apart from the substrate, and be free to rotate around an elongate axis of the multiwall nanotube. | 12-24-2009 |
20090320606 | ACCESSIBLE STRESS-BASED ELECTROSTATIC MONITORING OF CHEMICAL REACTIONS AND BINDING - A sensor may include a substrate that has a cavity formed in a surface thereof. A diaphragm, having a conductive portion, may be suspended over the cavity, a selective coating may be present on a face of the diaphragm outside of the cavity, and a counterelectrode may be spaced from and in opposition to the diaphragm. The diaphragm may deform upon interaction of the selective coating with an analyte and thereby alter a capacitance of the sensor in a manner indicative of a degree of interaction. | 12-31-2009 |
