Filed:

Aug 1, 2007

Appl. No.:

11/832625

Inventors:

Daniel Peter Sheehan - San Diego CA, US

Assignee:

Paradigm Energy Research Corporation - Poway CA

International Classification:

B32B 3/00
B05D 1/12
G03C 5/00
C23C 14/00

US Classification:

428113, 257 52, 257 77, 257379, 257382, 257401, 428105

Abstract:

Surfaces are provided comprising an array of partially embedded nano-fibers. Two such surfaces may contact each other such that the respective nano-fibers contact at orthogonal angles, resulting in ultra-low friction and ultra-low adhesion contact. Such configurations are useful in several NEMS or MEMS applications, as well as macro-sized applications. Alternatively, the surfaces may contact each other such that the respective nano-fibers are parallel. These configurations are useful in micro-stage or high-order three-dimensional self assembly applications.

Abstract:

An Epicatalytic Thermal Diode (ETD) includes one or more ETD cells. Each cell comprises first and second surfaces with a cavity between them, which contains a gas that is epicatalytically active with respect to the pair of surfaces. The surfaces chemically interact with the gas such that the gas dissociates at a faster rate proximate to the first surface than it does proximate to the second surface. Thus, a steady-state temperature differential between the first surface and the second surface is created and maintained. In various applications, multiple ETD cells are connected in series and/or parallel.
