  • High temperature superconductor
    Patent number: 12239030
    Abstract: A superconductor device includes a high superconductivity transition temperature enhanced from the raw material transition temperature. The superconductor device includes a matrix material and a core material. The enhancing matrix material and the core material together create a system of strongly coupled carriers. A plurality of low-dimensional conductive features can be embedded in the matrix. The low-dimensional conductive features (e.g., nanowires or nanoparticles) can be conductors or superconductors. An interaction between electrons of the low-dimensional conductive features and the enhancing matrix material can promote excitations that increase a superconductivity transition temperature of the superconductor device.

  • Analytical methods and materials for nucleic acid detection
    Patent number: 6268146
    Abstract: Mass spectrometric, absorbance spectroscopic and fluorescence spectroscopic processes are disclosed to detect the depolymerization of a nucleic acid hybrid in order to qualitatively and quantitatively assay for the presence of a predetermined nucleic acid target. Applications of those processes include the detection of single nucleotide polymorphisms, identification of single base changes, speciation, determination of viral load, genotyping, medical marker diagnostics, and the like, including multiplexed assays.
