The metallic electron transport at the surface with good effective mobility can be effectively separated from the conduction of the bulk topological insulator and adjusted by field effect at a small gate voltage. Topological insulators, such as Bi2Se3, also have a magneto-electric effect that causes transistor threshold voltage shifts with external magnetic field.

    Abstract: Discussed herein are systems and methods of forming hardfacing coatings and films containing Q-carbon diamond particles for use in downhole drilling tooling and other tools where wear-resistant coating is desirable. The Q-carbon diamond-containing layers may be coated with matrix material and/or disposed in a matrix to form the coating, or the Q-carbon diamond layer may be formed directly from a diamond-like-carbon on a substrate.

  • Patent number: 10889914
    Abstract: The exemplary embodiments describe techniques for a controlled chemical vapor deposition growth and transfer of arrayed TMD monolayers on predetermined locations, which enable the formation of single crystalline TMD monolayer arrays on specific locations. The unique growth process includes the patterning of transition metal oxide (e.g., MoO3) on the source substrate contacting the growth substrate face-to-face, where the growth of single crystalline TMD monolayers with controlled size and location, exclusively on predetermined locations on the growth substrates is accomplished. These TMD arrays can be align-transferred using a unique process that combines the wet and stamping transfer processes onto any target substrate with a pin-point accuracy, which dramatically enhances the integrity of transferred TMDs.

  • Patent number: 10875282
    Abstract: A structural shape memory assisted self-healing polymer formed by laminating thin layers of an ionomer, such as a member of the poly(styrene sulfonate) (PSS) family of ionomers, with a WEGP-type SMP, such as atactic poly(styrene) (PS) with molecular weight in the 200 kDa range (or alternatively poly(methyl methacrylate) (PMMA)) in combination with polycyclooctene (PCO). The self-healing polymer may also comprise an interpenetrating, immiscible polymer network (IPN) based on a blend of polystyrene and polystyrene sulfonate (PSS).

  • Patent number: 10876200
    Abstract: A hydrogenated diamond-like coating (“H-DLC”) for metallic substrates provides improved reliability. The H-DLC is relatively soft and elastic. Unlike hard and/or inelastic coatings in the prior art, the present coatings do not exhibit a loss of adhesion (delamination). A bonding layer may be used between the metallic substrate and the H-DLC. H-DLC coatings can, for example, be used in bearings and gears to reduce the occurrence of micropits and, ultimately, product failure.

  • Patent number: 10864301
    Abstract: Nerve scaffolds are described that include a tubular outer housing fabricated from a biocompatible polymer, within which are disposed a plurality of carbon nanofiber yarns. The carbon nanofiber yarns, which can be separated by distances roughly corresponding to an average nerve fiber diameter, provide surfaces on which nerve fibers can regrow. Because the proximate carbon nanofiber yarns can support individual nerve fibers, a nerve can be regenerated with a reduced likelihood of undesirable outcomes, such as nerve pain or reduced nerve function.

  • Patent number: 10836132
    Abstract: Graphene reinforced materials and related methods of manufacture are provided. The graphene reinforced materials include graphene sheet or scroll, graphene-polymer sheet or scroll, and graphene-carbon sheet or scroll, each having material properties that are attractive across a broad range of applications and industries. The graphene reinforced materials generally include monolayer or multilayer graphene that is synthesized by annealing a catalyst substrate within a CVD chamber, introducing a hydrocarbon gas as a carbon source with the CVD chamber to form a layer of graphene on the catalyst substrate, detaching the catalyst substrate from the layer of graphene, and rolling the layer of graphene onto itself to form a scroll, optionally with the addition of a polymer layer or carbonized layer on the graphene layer.

  • Patent number: 10823291
    Abstract: A mechanical seal includes a rotating ring on a rotary shaft, a stationary ring facing the rotating ring in an axial direction, and an elastic means configured to press the rotating ring or the stationary ring toward each other to contact opposed sealing surfaces of the rotating ring and the stationary ring. The mechanical seal partitions a first space and a second space. The first space and the second space are located in the axial direction with the sealing surface interposed therebetween. The stationary ring is made of a sintered compact of SiC. A diamond film is formed on a sealing surface of the stationary ring facing the rotating ring. A diamond film continuous with the diamond film of the sealing surface is formed on an outer circumferential surface or an inner circumferential surface of the stationary ring. Volume resistivity of the stationary ring is 101 to 104 ?·cm.

  • Patent number: 10822280
    Abstract: A method of making a fiber preform for ceramic matrix composite (CMC) fabrication comprises laminating an arrangement of fibers between polymer sheets comprising an organic polymer, which may function as a fugitive binder during fabrication, to form a flexible prepreg sheet. A plurality of the flexible prepreg sheets are laid up in a predetermined geometry to form a stack, and the stack is heated to soften the organic polymer and bond together the flexible prepreg sheets into a bonded prepreg structure. Upon cooling of the bonded prepreg structure, a rigid preform is formed. The rigid preform is heated at a sufficient temperature to pyrolyze the organic polymer. Thus, a porous preform that may undergo further processing into a CMC is formed.
