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： 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 BNNTs 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： 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： Orbital debris removal (ODR) systems under the present approach may use a ground- or surface-based FEL and mirror system with sufficient power and both spatial and temporal resolution to both locate Category II OD (1 cm to 10 cm diameter) in low Earth orbit (LEO, 160 to 2000 km altitude) and remove these objects from orbit. Locating the Category II OD is performed by having the light beam from an FEL and its beam director scan a volume of space of interest and then observing the light reflected from the OD. Removing the OD may include heating the OD to a sufficiently high temperature to evaporate the OD, changing the orbit of the OD such as to lower the perigee, or both. Megawatt-class MOPA FELs for, inter alia, removing OD, are described.

摘要： High quality Boron Nitride Nanotubes (BNNTs) may be synthesized by heating a boron melt target via one or more laser diodes, including laser diode stacks. The use of a diode stack and beam shaping optics to irradiate the boron melt eliminates the need for a conventional laser cavity as has been employed with previous embodiments. The diode arrangements facilitate managing power distribution on the born melt(s), nitrogen gas flows, and blackbody radiation that drive the BNNT self-assembly process. These parameters may be used for controlling the proportions and characteristics of boron species, a-BN particles, h-BN nanocages, and h-BN nano sheets in the as- synthesized BNNT material while enhancing the quality of the BNNTs.

摘要： Boron nitride nanotubes (BNNTs) having a second scintillating material, and in some embodiments an enhanced 10B content, may be used for efficient thermal neutron detection. The second scintillating material may be a crystal coating on the nanotubes, and/or crystal dispersed within the BNNT material. Crystal-coated BNNT materials enable 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 crystal-coating. Embodiments of thermal neutron detectors are described. Methods for preparing BNNTs with a second scintillating material are also described.

摘要： Thermoresponsive composite switch (TRCS) membranes for ion batteries include a porous scaffolding providing ion channels and a thermoresponsive polymer coating. Boron nitride nanotube (BNNT)/polymer composite TRCS membrane embodiments are preferable due to unique BNNT properties. A BNNT scaffold coated with one or more polymers may form a composite separator with tunable porosity (porosity level and pore size distribution), composition, wettability, and superior electronic isolation, oxidative/reduction resistance, and mechanical strength. The BNNT/polymer composite TRCS membrane optimizes the performance of ion batteries with tunable separator thicknesses that may be under 5μιη. Nano- scale porosity with thin separator thicknesses improves the charge density of the battery. Nano- scale architecture allows for reversible localized switching on the nano scale, in proximity to thermally stressed ion substrates. Polymer thermal expansion will decrease porosity at temperatures approaching the thermal runaway point. The BNNT polymers composite therefore functions as a TRCS.

摘要： Boron nitride nanotubes (BNNTs) with 10B 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.
