  • Patent number: 9702676
    Abstract: Munitions structures comprising one or more high strength reactive alloys, in particular reactive bulk metallic glasses, have significant amounts of inherent chemical energy. This energy may be discharged by subjection of the munitions structure to rapid impulsive loading and fragmentation in the presence of oxygen and/or nitrogen. A munitions structure can be configured in both large and small penetrators, e.g. warheads and bullets, with increased lethality. The lethality of these munitions structures is augmented by means of rapidly and simultaneously imparting both mechanical energy (kinetic energy through impact and fragmentation) and chemical energy (blast and/or fireball) to a target. A high-strength reactive alloy can substitute at least in part one or both of explosives and inert structural materials in conventional munitions systems to improve performance and reduce parasitic weight of structural casing.

  • Patent number: 9331340
    Abstract: A catalytic ink preparation method comprises mixing a first ion conducting body and a catalyst, preparing a first ink, and concentrating the first ink. The method is characterized by further comprising a step of adding a second ion conducting body to the concentrated first ink. With such a catalytic ink preparation method, the quantity of solvent in the first ion conducting body is reduced by concentration. In other words, the first ion conducting body adheres to the catalyst, and re-dissolution is not prone to occurring with the first ion conducting body when the second ion conducting body is added. Thus, it is possible to efficiently manufacture an electrode catalyst in which a significant part of the surface of the catalyst is covered with two ionomer layers, and there is almost no portion which is covered with only one ionomer layer.

  • Patent number: 9034274
    Abstract: The present invention relates to a vehicular air cleaner. A DOR (Direct Ozone Reduction) system for suppressing deterioration of a purifying function of an ozone purifying material is provided. Active oxygen is produced by an ozone purifying function of activated carbon. The probability that the active oxygen contacts with a fin of a radiator on a rear surface side is higher than that on a front surface side of the radiator. Accordingly, the activated carbon on the rear surface side of the radiator is easily oxidized as compared with the activated carbon on the front surface side. Therefore, in the fin, a coating amount of the activated carbon on the front surface side of the radiator is adjusted to be larger than a coating amount of the activated carbon on the rear surface side. Thus, the probability that the active oxygen contacts with the activated carbon can be reduced.

    Abstract: A method of fabricating composite filaments is provided. An initial composite filament including a core and a cladding (such as a Pt-group metal) is cut into smaller pieces (or is first mechanically reduced and then cut into smaller pieces). The smaller pieces of the filaments are inserted into a metal matrix, and the entire structure is then further reduced mechanically in a series of reduction steps. The process can be repeated until the desired cross sectional dimension of the filaments is achieved. The matrix can then be chemically removed to isolate the final composite filaments with the cladding thickness down to the nanometer range. The process allows the organization and integration of filaments of different sizes, compositions, and functionalities into arrays suitable for various applications.

    Abstract: A pass-through catalytic substrate can comprise a plurality of porous ceramic substrate walls defining flow channels extending between an inlet end and an outlet end of the catalytic substrate. The pass-through catalytic substrate can include a plurality of porous ceramic beveled corner portions positioned at intersecting corners of the substrate walls within the flow channels. In one example, the porous ceramic beveled corner portions each include a heat capacity less than about 1.38 J/cm3/K. In another example, a catalytic washcoat layer can be provided for coating the porous ceramic substrate walls and the porous ceramic beveled corner portions. Methods for producing a pass-through catalytic substrate also provide porous ceramic beveled corner portions.
