Patent number: 7445742Abstract: A method and mold for creating nanoscale patterns in an ion-selective polymer membrane is provided, in which a mold comprising a substrate and a molding layer having at least one protruding feature is imprinted on the ion-selective polymer membrane, thereby creating a recessed feature in the membrane. Protruding features having nanoscale dimensions can be created, e.g., by using self-assembled nanostructures as a shadow mask for etching a molding layer. In one embodiment, an imprinted ion selective polymer membrane, suitable for use as a solid electrolyte, is adapted for use in an electrochemical device or fuel cell by adding a metal catalyst to one portion of the membrane to serve as a catalytic electrode.Type: GrantFiled: August 15, 2003Date of Patent: November 4, 2008Assignee: Hewlett-Packard Development Company, L.P.Inventors: Yong Chen, David Hacklernan, Laurie S.

Patent number: 6869712Abstract: A method for roughening a surface of an ion exchange system structure using laser interaction with a surface. The laser surface roughening process allows the use of a wide range of substrates such as metals, ceramics, silicates, polymers and the like, including varieties which can not be fabricated in a fine fibrous structure. The surface roughened ion exchange system structure may be used as an ion-exchange media in applications such as fuel cells, batteries, and other catalysis systems where a high surface exchange area is desirable.Type: GrantFiled: March 7, 2002Date of Patent: March 22, 2005Assignee: Hewlett-Packard Development Company, L.P.Inventors: Laurie S. Mittelstadt, Joshua W. Smith

Patent number: 6033628Abstract: In a method of forming a microchannel and/or microcavity structure by bonding together two elements (1, 2) having opposed plane surfaces of the same or different material, one or both surfaces having open channels and/or cavities, bonding is effected by applying to one or both element surfaces (1, 2) a thin layer (3) of a solution of a material capable of fusing with and having a lower melting point than that of the material or materials of the two element surfaces (1, 2) in a solvent which substantially does not dissolve the element surface material or materials. The solvent is then removed, and the two elements (1, 2) are brought together and heated to a temperature where the dissolved material is caused to melt but not the element surface material or materials.Type: GrantFiled: April 27, 1998Date of Patent: March 7, 2000Assignee: Agilent Technologies, Inc.Inventors: Patrick Kaltenbach, Sally A.
