    Abstract: 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, and providing additional heat via lasers or electric arcs. Direct Induction processes may be energy efficient and sustainable for indefinite period of time. Careful heat and gas flow profile management may be used to enhance production of high quality BNNT at significant production rates.

  • Patent number: 10669436
    Abstract: An electrically conductive paint/caulk is disclosed that may be applied by spraying, rolling, and/or brushing using conventional techniques/may be dispensed from a tube. The electrically conductive paint/caulk has a plurality of metal-coated fibers precision chopped to short lengths, optionally a plurality of conductive filament structures having a high-aspect ratio, and a polymer base. The metal-coated fibers and optional conductive filament structures are dispersed uniformly within the polymer base to create a complex electron transport system facilitating conductivity sufficient for a full range of electromagnetic properties including electrostatic dissipation, electrostatic discharge, and shielding. The complex electron transport system created facilitates the full range of electromagnetic properties with lower loadings of conductors, reduces viscosity, and the additional unloaded portion of paint/caulk receives other multifunctional additives.
