1. United States Patent 8280214
Application No.: 11/559,244
Issue Date: October 2, 2012
Title: Nanoribbon and Nanoribbons as Subwavelength Optical Waveguides and Their Use as Components in Photonic Circuits and Devices
Inventor(s): M. Law, D. Sirbuly, J. Johnson, R. Saykally, P. Yang
Abstract: Nanoribbons and nanowires having diameters less than the wavelength of light are used in the formation and operation of optical circuits and devices. Such nanostructures function as subwavelength optical waveguides which form a fundamental building block for optical integration. The extraordinary length, flexibility and strength of these structures enable their manipulation on surfaces, including the precise positioning and optical linking of nanoribbon/wire waveguides and other nanoribbon/wire elements to form optical networks and devices. In addition, such structures provide for waveguiding in liquids, enabling them to further be used in other applications such as optical probes and sensors.

File Date: September 18, 2009
Application No.: 12/529,884
Issue Date: February 12, 2013
Title: Method and Apparatus for Electrokinetic Co-Generation of Hydrogen and Electric Power from Liquid Water Microjets
Inventor(s): Richard J. Saykally; Andrew M. Duffin; Kevin R. Wilson; Bruce S. Rude
Abstract: A method and apparatus for producing both a gas and electrical power from a flowing liquid, the method comprising: a) providing a source liquid containing ions that when neutralized form a gas; b) providing a velocity to the source liquid relative to a solid material to form a charged liquid microjet, which subsequently breaks up into a droplet spay, the solid material forming a liquid-solid interface; and c) supplying electrons to the charged liquid by contacting a spray stream of the charged liquid with an electron source. In one embodiment, where the liquid is water, hydrogen gas is formed and a streaming current is generated. The apparatus comprises a source of pressurized liquid, a microjet nozzle, a conduit for delivering said liquid to said microjet nozzle, and a conductive metal target sufficiently spaced from said nozzle such that the jet stream produced by said microjet is discontinuous at said target. In one arrangement, with the metal nozzle and target electrically connected to ground, both hydrogen gas and a streaming current are generated at the target as it is impinged by the streaming, liquid spray microjet.
