  • Patent number: 10230101
    Abstract: Provided are examples of electrochemically active electrode materials, electrodes using such materials, and methods of manufacturing such electrodes. Electrochemically active electrode materials may include a high surface area template containing a metal silicide and a layer of high capacity active material deposited over the template. The template may serve as a mechanical support for the active material and/or an electrical conductor between the active material and, for example, a substrate. Due to the high surface area of the template, even a thin layer of the active material can provide sufficient active material loading and corresponding battery capacity. As such, a thickness of the layer may be maintained below the fracture threshold of the active material used and preserve its structural integrity during battery cycling.

  • Patent number: 8932663
    Abstract: Methods for forming bone implants for the repair of the ends of bones at orthopedic joints, which implants have a Young's modulus close to that of human cortical bone. Substrates of dense isotropic graphite are coated overall with hard, microporous, isotropic pyrocarbon of specific character such that it can be polished to serve as an articular surface and can also securely receive an anchoring first metal layer through PVD. The first layer has a character such that, by thermal spraying a second biocompatible metal layer thereupon, fusion occurs and thereby anchors an outermost layer that is formed with a network of randomly interconnected pores and a surface character of peaks and valleys designed to promote enhanced appositional growth of cortical bone at the interface therewith.

  • Patent number: 8932673
    Abstract: A method for fabricating large-area, high-quality Graphene product. Specifically, the fabrication method uses a seed layer of exfoliated Graphene in combination with a substrate and a catalyst metal layer and introduces Carbon atoms to the Graphene seed, causing growth of high-quality Graphene product. The method of the invention combines some steps of current mechanical exfoliation techniques with other steps of the CVD process and adds a new technique to the fabrication method involving seed-based catalyst of large-area Graphene product growth.

  • Patent number: 8920871
    Abstract: Porous nuclear fuel elements for use in advanced high temperature gas-cooled nuclear reactors (HTGR's), and to processes for fabricating them. Advanced uranium bi-carbide, uranium tri-carbide and uranium carbonitride nuclear fuels can be used. These fuels have high melting temperatures, high thermal conductivity, and high resistance to erosion by hot hydrogen gas. Tri-carbide fuels, such as (U,Zr,Nb)C, can be fabricated using chemical vapor infiltration (CVI) to simultaneously deposit each of the three separate carbides, e.g., UC, ZrC, and NbC in a single CVI step. By using CVI, the nuclear fuel may be deposited inside of a highly porous skeletal structure made of, for example, reticulated vitreous carbon foam.

  • Publication number: 20140377462
    Abstract: By flowing an amount of hydrogen gas (25-75% of total flow), the stress of thin carbon films (100 nm-10 ?m) can be reduced. The films are deposited by chemical vapor deposition (800° C.-1100° C.) using an ethylene source gas (remainder of total flow). Carbon nanotube structures infiltrated with carbon by this method will not delaminate from the growth substrate, allowing for a range of post-processing methods. One process that can be performed is to etch the carbon “floor layer”, coat the structures in a Formvar film, and then release the structures using a chemical etch. Thin films (5-100 nm) can then be deposited on the substrate-defined Formvar surface. The Formvar can be removed by a thermal annealing step (400-600° C.), or a chemical etch step, either of which will leave suspended thin films over the open portions of the structures.

  • Patent number: 8871302
    Abstract: A method for synthesizing graphene films is disclosed. Monolayer or multilayer graphene can be directly grown on the dielectric materials. The method includes the following steps: disposing dielectric materials and metals in a reactor, introducing reaction gases into the reactor and decomposing the reaction gases by heating, thus directly depositing graphene films on the surfaces of the dielectrics. High crystalline quality and low-defect graphene films can be synthesized directly on dielectric materials, without the process of wet etching and transfer. The method opens up a more direct route to apply graphene on electronics, optoelectronics, and bio-medical devices.
