  • Bis(aniline) compounds containing multiple substituents with carbon-carbon triple-bonded groups
    Patent number: 11608310
    Abstract: The invention relates to bis(aniline) compounds containing multiple arylethynyl, alkylethynyl, ethynyl groups or their combinations, processes of making such compounds and materials comprising such compounds. Such, bis(aniline) compounds preferably comprise multiple phenylethynyl (PE) groups, i.e. 2-4 PE moieties. Such compounds are useful monomers for the preparation of polyimides, polyamides and poly(amide-imides) whose post-fabrication crosslinking chemistry (i.e. reaction temperature) can be controlled by the number of PE per repeat unit as well as finding utility in thermosetting matrix resins, 3D printable resins, and as high-carbon-content precursors to carbon-carbon composites.

  • ROUNDED PROJECTILES FOR TARGET DISRUPTION
    Publication number: 20230083139
    Abstract: Provided are methods and related devices for disrupting an explosive device using a propellant driven disrupter (PDD) that propels a rounded projectile (RP) toward an explosive device. The RP travels along a linear trajectory and impacts the target, including a barrier portion of the explosive device. The impacting between the RP and barrier forms a composite projectile via a solid state weld between a portion of the barrier and the RP distal end, thereby minimizing or avoiding spall and fragment generation into the explosive device. The projectile traverses a penetration distance along the linear trajectory, or a defined-angle relative thereto, to disrupt the explosive device without unwanted explosive detonation.

  • High-Temperature Superconducting Striated Tape Combinations
    Publication number: 20230081740
    Abstract: This disclosure teaches methods for making high-temperature superconducting striated tape combinations and the product high-temperature superconducting striated tape combinations. This disclosure describes an efficient and scalable method for aligning and bonding two superimposed high-temperature superconducting (HTS) filamentary tapes to form a single integrated tape structure. This invention aligns a bottom and top HTS tape with a thin intervening insulator layer with microscopic precision, and electrically connects the two sets of tape filaments with each other. The insulating layer also reinforces adhesion of the top and bottom tapes, mitigating mechanical stress at the electrical connections. The ability of this method to precisely align separate tapes to form a single tape structure makes it compatible with a reel-to-reel production process.

  • FRAGMENTATION RESILIENCE ENERGY MASS SPECTROMETRY (FREMS)
    Publication number: 20230080152
    Abstract: Examples are directed toward collecting, by a LC-MS device, a full scan of ion chromatograms of a sample. The LC-MS device determines observed ions contained in the full scan, based on mass-to-charge ratios (m/z), and determines, for a formation curve of an observed ion, a formation point at which fifty percent of the observed ion has formed. The LC-MS device determines a fragmentation curve of a precursor ion, based on a fragmentation point of the fragmentation curve equivalent to the formation point at which fifty percent of the precursor ion has fragmented, and identifies the precursor ion by referencing the LC-MS library to confirm that the observed ion is a product of the fragmentation of the precursor ion. The LC-MS device indicates a goodness of fit between the fragmentation curve, as observed, and a model fragmentation curve, as stored in the LC-MS library.
