    Abstract:

    Background: The slowest reaction in the first CNO cycle is 14N(p,γ ) 15O, therefore its rate determines the overall energy production efficiency of the entire cycle. The cross section presents several strong resonance contributions, especially for the ground-state transition. Some of the properties of the corresponding levels in the 15O compound nucleus remain uncertain, which affects the uncertainty in extrapolating the capture cross section to the low energy range of astrophysical interest….

    Patent Number:
    US 8456635 B2
    Description:

    Example methods and apparatus for obtaining suspended particle information are disclosed. A disclosed example method includes emitting light from a light source, dividing the light source into a first path and a second path, and directing the first path to a first container comprising a plurality of particles in a suspension material. The example method also includes directing the second path to a second container containing a suspension material devoid of particles, retrieving a first transm…

    Patent Number:
    US 9082923 B2
    Description:

    Disclosed is a method and apparatus for strongly enhancing vortex pinning by conformal crystal arrays. The conformal crystal array is constructed by a conformal transformation of a hexagonal lattice, producing a non-uniform structure with a gradient where the local six-fold coordination of the pinning sites is preserved, and with an arching effect. The conformal pinning arrays produce significantly enhanced vortex pinning over a much wider range of field than that found for other vortex pinni…

    Patent Number:
    US 9366612 B2
    Description:

    An apparatus for obtaining suspended particle information includes an optical array to divide light to a first path and a second path, a platform to orient a first and second container with either the first or second path, and a first and second photodetector to receive at least a direct illuminating component of the light of the first and second path after said light penetrates through the first and second container. A detector interface receives transmission signals from the first and secon…

    Patent Number:
    US 6445869 B2
    Description:

    A sealed fiber-optic bundle feedthrough by which a multitude of fiber-optic elements may be passed through an opening or port in a wall or structure separating two environments at different pressures or temperatures while maintaining the desired pressure or temperature in each environment. The feedthrough comprises a rigid sleeve of suitable material, a bundle of individual optical fibers, and a resin-based sealing material that bonds the individual optical fibers to each other and to the rig…

    Patent Number:
    US 9580323 B2
    Description:

    The invention provides methods for the combustion synthesis (CS) of graphene by a novel exothermic self-sustained reaction between a refractory ceramic compound and a carbon-containing polymer under an inert gas atmosphere. The synthesis of graphene was confirmed by both transmission electron microscopy and Raman spectroscopy. The graphene produced has very low (<1 wt. %) oxygen content. Fluorocarbon gases released due to decomposition of the carbon-containing polymer in the combustion wav…
