  • Patent number: 10910638
    Abstract: A non-amorphous hard carbon material, synthesized from Furan-ring containing compounds, is described. These non-amorphous hard carbon materials have a d002 peak in their X-ray diffraction patterns, corresponding to an interlayer spacing of >3.6 ?, along with a prominent D-band peak in their Raman spectra. BET surface area values between 2 m2/gm and around 100 m2/gm can be obtained by controlling the processing parameters of temperature, time and heating rate. The higher surface area HCs—in Li-ion and Na-ion anode configurations—are capable of high charging rates up to 100 C with a cycle life of up to 1000 cycles. Composites of these non-amorphous hard carbons with silicon and lithium compounds are also disclosed.

  • Patent number: 10782190
    Abstract: A resistance temperature detector (RTD) that uses a ceramic matrix composite (CMC), such as a silicon carbide fiber-reinforced silicon carbide matrix, as an active temperature sensing element, which can operate at temperatures greater than 1000° C. or even 1600° C. Conductive indium tin oxide or a single elemental metal such as platinum is deposited on a dielectric or insulating layer such as mullite or an environmental barrier coating (EBC) on the substrate. Openings in the layer allow etching of the CMC surface in order to make high quality ohmic contacts with the conductive material, either directly or through a silicide diffusion barrier such as ITO. The RTD can measure both temperature and strain of the CMC. The use of an EBC, which typically is deposited on the CMC by the manufacturer, as the insulating or dielectric layer can be extended to other devices such as strain gages and thermocouples that use the CMC as a sensing element. The EBC can be masked and etched to form the openings.

  • Patent number: 9318295
    Abstract: A CNT electron source, a method of manufacturing a CNT electron source, and a solar cell utilizing a CNT patterned sculptured substrate are disclosed. Embodiments utilize a metal substrate which enables CNTs to be grown directly from the substrate. An inhibitor may be applied to the metal substrate to inhibit growth of CNTs from the metal substrate. The inhibitor may be precisely applied to the metal substrate in any pattern, thereby enabling the positioning of the CNT groupings to be more precisely controlled. The surface roughness of the metal substrate may be varied to control the density of the CNTs within each CNT grouping. Further, an absorber layer and an acceptor layer may be applied to the CNT electron source to form a solar cell, where a voltage potential may be generated between the acceptor layer and the metal substrate in response to sunlight exposure.

  • Patent number: 9211504
    Abstract: Carbon molecular sieves (CMS) membranes having improved thermal and/or mechanical properties are disclosed herein. In one embodiment, a carbon molecular sieve membrane for separating a first and one or more second gases from a feed mixture of the first gas and one or more second gases comprises a hollow filamentary carbon core and a thermally stabilized polymer precursor disposed on at least an outer portion of the core. In some embodiments, the thermally stabilized polymer precursor is created by the process of placing in a reaction vessel the carbon molecular sieve membrane comprising an unmodified aromatic imide polymer, filling the reaction vessel with a modifying agent, and changing the temperature of the reaction vessel at a temperature ramp up rate and ramp down rate for a period of time so that the modifying agent alters the unmodified aromatic imide polymer to form a thermally stabilized polymer precursor.

  • Publication number: 20150054187
    Abstract: In a method for producing a carbonaceous film in which a polymer film is wrapped around a core and is subjected to a heat treatment, material film surfaces during the carbonization step are prevented from fusion, whereby a long carbonaceous having a large area film is obtained. Fusion can be prevented by subjecting a polymer film to a heat treatment under a reduced pressure, and under a reduced pressure while allowing an inert gas to flow. The range of the pressure reduction is preferably ?0.08 MPa to ?0.01 kPa. It is preferred to carry out carbonization with the pressure reduced in the range of from ?0.08 MPa to ?0.01 kPa while allowing an inert gas to flow.
