  • Inventor(s):
    Boldizsár Jankó, Cynthia Reichhardt, Charles Reichhardt, Dipanjan Ray
    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…

  • Inventor(s):
    Steven Ruggiero, Carol Tanner
    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…

  • Inventor(s):
    Steven Ruggiero, Carol Tanner
    Patent Number:
    US 8867039 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…

  • Inventor(s):
    Alexander Mukasyan, Khachatur Manukyan
    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…

  • Inventor(s):
    Carol Tanner, Steven Ruggiero
    Patent Number:
    US 9447456 B2
    Description:

    Methods and systems of quantifying a target material in solution include detection of a size change of a hybridized nucleic acid complex, without the use of nanobeads. In particular, the examples include providing a plurality of nucleic acid fragments and a species-specific oligonucleotide tags, measuring the size of the nucleic acid fragments and/or oligonucleotides to predetermine a standard distribution of the solution(s), introducing the oligonucleotides in a solution containing nucleic a…

    Patent Number:
    US 9657336 B2
    Description:

    Methods and systems of quantifying a target material in solution include detection of a size change of a hybridized nanoparticle. In particular, the examples include functionalizing a plurality of nanoparticles to adapt the nanoparticles to hybridize with a species-specific target material, measuring the size of the functionalized nanoparticles to predetermine a standard distribution of non-hybridized nanoparticles, introducing the functionalized nanoparticles in a solution containing species…
