Abstract:

A method for forming a film of material using chemical vapor deposition. The method includes providing a substrate comprising a pattern of at least one metallic nanostructure, which is made of a selected material. The method includes determining a plasmon resonant frequency of the selected material of the nanostructure and exciting a portion of the selected material using an electromagnetic source having a predetermined frequency at the plasmon resonant frequency to cause an increase in thermal energy of the selected material. The method includes applying one or more chemical precursors overlying the substrate including the selected material excited at the plasmon resonant frequency and causing selective deposition of a film overlying at least the portion of the selected material.

International Classification:

F15C 1/04

US Classification:

137 1, 417 53, 417207, 137828

Abstract:

A method of microfluidic control via localized heating includes providing a microchannel structure with a base region that is partially filled with a volume of liquid being separated from a gas by a liquid-gas interface region. The base region includes one or more physical structures. The method further includes supplying energy input to a portion of the one or more physical structures within the volume of liquid in a vicinity of the liquid-gas interface region to cause localized heating of the portion of the one or more physical structures. The method also includes transferring heat from the portion of the one or more physical structures to surrounding liquid in the vicinity of the liquid-gas interface region and generating an interphase mass transport at the liquid-gas interface region or across a gas bubble while the volume of liquid and the gas remain to be substantially at ambient temperature.

Appl. No.:

6/781046

Inventors:

David T. Boyd - Irvine CA

International Classification:

B60J 1100

US Classification:

293128

Abstract:

A protective cover primarily for attachment to the side exterior surface of a vehicle such as an automobile and comprising a substantially rectangular flexible material such as a vinyl fabric to which an elongated strap is affixed for encircling the car door or window thereby rendering the cover resistant to unauthorized removal. Optional lower hooked straps provide means for affixing the bottom edge of the invention to the vehicle door panel and an optional rod contained within an elongated pocket, parallel to the elongated strap, provides added protection of the vehicle surface.

Abstract:

A method for forming graphene includes providing a substrate, subjecting the substrate to a reduced pressure environment, and providing a carrier gas and a carbon source. The method also includes exposing at least a portion of the substrate to the carrier gas, the carbon source, and at least one atmospheric gas and performing a CMOS compatible etching process on the at least a portion of the substrate. The method further includes performing, concurrently with the performing the CMOS compatible etching process, a CMOS compatible graphene growth process to convert a portion of the carbon source to graphene on the at least a portion of the substrate.
