Abstract: A molded dichroic mirror and method of manufacture thereof. The dichroic minor may be molded from polysiloxane or lithia potash borosilicate and may be coated to reflect an infrared signal and configured to transmit a radio frequency signal between 33 GHz and 37 GHz.

Abstract: Embodiments of a flight vehicle including a scribed frangible seal are provided, as are embodiments of a scribed frangible seal and a method for equipping a flight vehicle with a scribed frangible seal. In one embodiment, the flight vehicle includes a vehicle body having a deployment opening therein, and a deployable element residing in a stowed position within the vehicle body and movable into a deployed position. At least a potion of the deployable element passes through the deployment opening when moving from the stowed position into the deployed position. The flight vehicle further includes a scribed frangible seal, which is sealingly disposed over the deployment opening and which is positioned so as to be contacted by the deployable element during deployment thereof. The scribed frangible seal fractures along at least one scribe line when contacted by the deployable element to permit movement of the deployable element from the stowed position to the deployed position.

Abstract: A system and method for growing nanotubes out of carbon and other materials using CVD uses a catalytic transmembrane to separate a feedstock chamber from a growth chamber and provide catalytic material with separate catalytic surfaces to absorb carbon atoms from the feedstock chamber and to grow carbon nanotubes in the growth chamber. The catalytic transmembrane provides for greater flexibility to independently control both the gas environment and pressure in the chambers to optimize absorption and carbon growth and to provide instrumentation in the growth chamber for in-situ control of defects or observation of the carbon nanotube growth.

Abstract: Ion implantation is used to grow nanotubes out of carbon and other materials. Catalytic material is placed on or in a membrane that physically and possibly environmentally separates an implantation chamber or region from a growth chamber or region. High-energy ions are implanted into the catalytic material from one side to grow nanotubes on an exposed surface in the growth chamber. Ion implantation via the membrane provides for greater flexibility to separate and independently control the implantation and growth processes.

Abstract: Strengthened filaments and fibers are realized by mixing and dissolving monomer and catalyst in a solvent into open-ended nanotubes to form a polymer precursor prior to polymerization in which the open nanotubes are filled with monomer and catalyst. The remaining steps for forming a stabilized filament may follow the conventional sequence. The result is that the nanotubes are “doubly-embedded” in the polymer matrix (bonds to the polymer inside and extending through the nanotube and bonds to other polymer chains outside the nanotube) in the filament. These additional bonds provide additional mechanical strength. The number of bonds may be further enhanced by pretreating the nanotubes to create defects in the nanotubes to form sites along the inner and outer walls for additional polymer-to-nanotube bonds.

Abstract: An internally-sealed pass-through electrical connector includes electrical conductors for carrying electrical signals through the electrical connector, a connector body or shell surrounding the connector, and an organic adhesive material within the body or shell that fills space around the conductors and between the conductors and the connector body. The connector body includes a metal portion, such as an aluminum portion, that has a roughened surface to better allow the adhesive to adhere to it. The roughened surface may be a grit blasted surface. The connector body may also include a plastic portion, such as a molded lead organizer, to aid in positioning the leads. The adhesive may have a coefficient of thermal expansion that is matched to that of the metal portion of the connector body or shell. The organic adhesive may be an epoxy material. The electrical connector may have any of a variety of configurations.
