Abstract:
A surface-treated carbon fiber having a mole ratio between a carboxyl group and an acid anhydride of 50:50 to 70:30 when measured by pyrolysis gas analysis, is manufactured by spraying a reactive gas that has been made into a plasma onto the surface of a carbon fiber and introducing a functional group into the surface of the carbon fiber.

Abstract:
In a composition including a plurality of coated diamond nanoparticles, each diamond nanoparticle may have at least one silane functional group covalently bonded to a surface thereof. A method of forming coated diamond nanoparticles may include functionalizing surfaces of diamond nanoparticles with at least one of a fluorine-containing compound and an oxidant; dispersing the functionalized diamond nanoparticles in a solvent comprising a silane functional group; and forming covalent bonds between the silane functional group and the diamond nanoparticles. A method of forming a diamond coating may include depositing the diamond nanoparticles over a substrate.
Abstract:
A composite includes a substrate, a binder layer disposed on a surface of the substrate; and a nanofiller layer comprising nanographene and disposed on a surface of the binder layer opposite the substrate. In addition, a nano-coating layer for coating a substrate includes multiple alternating layers of the binder layer and the nanofiller layer. Articles coated with the nano-coating layer prepared from alternating layers of nanofiller layer and binder layer have improved barrier properties, and may be used in down-hole applications.

Abstract:
Methods and apparatus for removing deposits in self-assembled monolayer (SAM) based selective deposition process schemes using cryogenic gas streams are described. Some methods include removing deposits in self-assembled monolayer (SAM) based selective depositions by exposing the substrate to cryogenic aerosols to remove undesired deposition on SAM protected surfaces. Processing chambers for cryogenic gas assisted selective deposition are also described.
