The precursor thin film can be patterned on the substrate to limit the locations of the catalyst material to well-defined areas. Methods for nanotube synthesis employ CVD in conjunction with the catalyst materials of the invention. During the synthesis, the catalyst nanoparticles catalyze carbon nanotubes to grown from a carbon-containing gas.Type: ApplicationFiled: June 22, 2007Publication date: July 3, 2008Inventors: Gang Gu, Lawrence Pan, Lian Zhang

Patent number: 7334630Abstract: Apparatus and methods according to the present invention utilize micropumps that are capable of generating high pressure and flow without moving mechanical parts and the associated generation of unacceptable electrical and acoustic noise, as well as the associated reduction in reliability. These micropumps are fabricated with materials and structures that improve performance, efficiency, and reduce weight and manufacturing cost relative to presently available micropumps. These micropumps also can allow for recapture of evolved gases and deposited materials, which may provide for long-term closed-loop operation. Apparatus and methods according to the present invention also allow active regulation of the temperature of the device through electrical control of the flow through the pump and can utilize multiple cooling loops to allow independent regulation of the spatial and temporal characteristics of the device temperature profiles. Novel enclosed microchannel structures are also described.Type: GrantFiled: May 25, 2005Date of Patent: February 26, 2008Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Kenneth E.
