摘要： Boron nitride nanotube (BNNT)-polyimide (PI) and poly-xylene (PX) nano-composites, in the form of thin films, powder, and mats may be useful as layers in electronic circuits, windows, membranes, and coatings. The processes described chemical vapor deposition (CVD) processes for coating the BNNTs with polymeric material, specifically PI and PX. The processes rely on surface adsorption of polymeric material onto BNNTs as to modify their surface properties or create a uniform dispersion of polymer around nanotubes. The resulting functionalized BNNTs have numerous valuable applications.

摘要： Thermal interface materials may be enhanced through the dispersion of refined boron nitride nanotubes (BNNTs) into a polymer matrix material and one or more microfillers. A refined BNNT material may be formed by reducing free boron particle content from an as-synthesized BNNT material, and in some embodiments reducing h-BN content. Reducing these species improves the thermal conductivity of the BNNTs. Refined BNNTs may be deagglomerated to reduce the size and mass of BNNTs in agglomerations when the deagglomerated BNNT material is dispersed into a target polymer matrix material. The deagglomerated BNNT material may be lyophilized prior to dispersion in the matrix material, to retain the deagglomeration benefit following return to solid state. The surface of the deagglomerated BNNT material may be modified, with one or more functional groups that improve dispersibility and heat transfer in the target polymer matrix material.

摘要： Transition radiation from nanotubes, nanosheets, and nanoparticles and in particular, boron nitride nanomaterials, can be utilized for the generation of light. Wavelengths of light of interest for microchip lithography, including 13.5 nm (91.8 eV) and 6.7 nm (185 eV), can be generated at useful intensities, by transition radiation light sources. Light useful for monitoring relativistic charged particle beam characteristics such as spatial distribution and intensity can be generated.

摘要： Described herein are processes and apparatus for the large-scale synthesis of boron nitride nanotubes (BNNTs) by induction-coupled plasma (ICP). A boron-containing feedstock may be heated by ICP in the presence of nitrogen gas at an elevated pressure, to form vaporized boron. The vaporized boron may be cooled to form boron droplets, such as nanodroplets. Cooling may take place using a condenser, for example. BNNTs may then form downstream and can be harvested.

摘要： Boron nitride nanotubes (BNNTs) with 1013 combined with a scintillation gas can serve as the basis for detecting thermal neutrons by detecting light from the decay products of the thermal neutron's absorption on the 10B atoms in the BNNT Material as the resultant decay products pass through the scintillating gas. BNNTs with 11B can be utilized as a scaffold for 238U and combined with a scintillation gas as the basis for detecting fast neutrons via detecting light from the fission decay products passing through the scintillating gas. Both technologies provide high spatial and temporal resolution for the detection of thermal neutrons and fast neutrons respectively.

摘要： High quality, catalyst-free boron nitride nanotubes (BNNTs) that are long, flexible, have few wall molecules and few defects in the crystalline structure, can be efficiently produced by a process driven primarily by Direct Induction. Secondary Direct Induction coils, Direct Current heaters, lasers, and electric arcs can provide additional heating to tailor the processes and enhance the quality of the BN-NTs while reducing impurities. Heating the initial boron feed stock to temperatures causing it to act as an electrical conductor can be achieved by including refractory metals in the initial boron feed stock, or providing additional heat via lasers or electric arcs. Direct Induction processes may be energy efficient and sustainable for indefinite periods of time. Careful heat and gas flow profile management may be used to enhance production of high quality BNNT at significant production rates.

摘要： In the synthesis of boron nitride nanotubes (BNNTs) via high temperature, high pressure methods, a boron feedstock may be elevated above its melting point in a nitrogen environment at an elevated pressure. Methods and apparatus for supporting the boron feedstock and subsequent boron melt are described that enhance BNNT synthesis. A target holder having a boron nitride interface layer thermally insulates the target holder from the boron melt. Using one or more lasers as a heat source, mirrors may be positioned to reflect and control the distribution of heat in the chamber. The flow of nitrogen gas in the chamber may be heated and controlled through heating elements and flow control baffles to enhance BNNT formation. Cooling systems and baffle elements may provide additional control of the BNNT production process.
