  • Patent number: 9475214
    Abstract: A method of preparing an aluminum mold for injection molding is provided, the method comprises the steps of providing an aluminum mold having a least one surface, subjecting the at least one surface to a gas or liquid phase silane to thereby form an anti-stiction coating, the anti-stiction coating comprising a chemically bonded monolayer of silane compounds on the at least one surface wherein the silane is a halogenated silane. The at least one surface coated with the anti-stiction coating may be configured to withstand an injection molding process at a pressure above 100 MPa. Furthermore, a mold having at least one closed cavity is provided, at least one surface of the at least one cavity being an aluminium surface coated with a silane based coating layer. The resistance of the coated aluminium mold is significantly improved by applying a silane-based coating layer.

  • Publication number: 20130256627
    Abstract: Sensors for detecting IR radiation, UV radiation, X-Rays, light, gas, and chemicals. The sensors herein incorporate freestanding carbon nanostructures, such as single-walled carbon nanotubes (“SWCNT”), atomically thin carbon sheets having a thickness of about between 1 atom and about 5 atoms (“graphene”), and combinations thereof. The freestanding carbon nanostructures are suspended above a substrate by a plurality of conductors, each conductor electrically connected to the carbon nanostructure. In one method of manufacture, a resonance chamber is formed under the carbon nanostructure by etching of the substrate, yielding a sensor wherein the resonance chamber is bounded by at least the substrate and the carbon nanostructure.
