US Patent 7988861 - Tangled nanotube growth

http://www.freepatentsonline.com/7988861.html

This patent from the Centre National de la Recherche Scientifique in Paris, France teaches a way to form larger catalyst material from carbon nanotubes. Claim 1 reads:

1. A process for preparing a solid material based on tangled nanofibres and/or nanotubes, comprising:

growing carbon nanotubes and/or nanofibres under constraint within a confined reactor, said growing comprising the following successive steps:

(a) growing the carbon nanotubes and/or nanofibres within the confined reactor, until the nanotubes and/or nanofibres formed occupy an essential of an internal space within the reactor; and

(b) continuing growth of the nanotubes and/or nanofibres under constraint, whereby material in formation applies pressure against the reactor walls.

US Patent 7559758 - Nanoimprinting stamp with flow ducts

http://www.freepatentsonline.com/7559758.html

Nanoimprint lithography offers a potential route to 10 nm lithography and better using a patterned stamp structure to shape a polymer or resin material. However, residual polymer and resin can require cleaning of the stamp surface and lack of uniformity in the patterned structures. This patent from the French National Center for Scientific Research teaches the formation of built-in ducts to remove access polymer and to facilitate uniformity of thickness in the material to be patterned. Claim 1 reads:

1. A mould for nano-printing, comprising recess and projection type patterns, said mould comprising:

one or several ducts, each providing a communication between a mould pattern and a reservoir area,

wherein a duct has a cross-section that is smaller than a surface area of a pattern at which the duct opens up.
