  • Patent number: 10712297
    Abstract: A method of probing the layers above, at, and below the surface of a conducting region includes exciting nuclear or electronic spins within the conducting region using a first frequency, receiving a second frequency from the conducting region, determining the length scales by the conductivity of the conducting region, the first frequency, and the second frequency, obtaining a depth profile of the conducting region, and indirectly measuring the presence of the surface by characterizing signal distortions above the surface.

  • Publication number: 20190310211
    Abstract: A method of diagnosing a conducting structure includes providing the conducting structure in a magnetic field, immersing the conducting structure in a detection medium, or placing a detection medium in the vicinity of the conducting structure, exciting nuclear or electronic spins within the detection medium using a broad-band excitation pulse, receiving an NMR or ESR spectrum from the detection medium, obtaining a frequency distribution of the detection medium, and indirectly measuring internal characteristics of the conducting structure by characterizing frequency changes in the frequency distribution. Conducting structures are analyzed on the basis of changes in magnetic susceptibilities and internal electric current distributions, which may change over the course of a charging/discharging cycle, and a result of degradation and failure of the conducting structure. The conducting structure may be, for example, a battery, a capacitor, a supercapacitor, a fuel cell, or a catalyst material.

  • Patent number: 9709511
    Abstract: Apparatus, system, method and computer-readable medium for isolating chemical exchange saturation transfer contrast from magnetization transfer asymmetry under two-frequency RF irradiation. A two-pool model for magnetization transfer (MT) can be established fully based on Provotorov's theory of saturation, and then extended to the situation of simultaneous two-frequency RF irradiation. Numerical simulations and experimental results demonstrate that two-frequency RF irradiation can make MT effects independent of irradiation frequency over a wide range, and thus can suppress MT asymmetry. Exemplary embodiments can be provided to isolate chemical exchange saturation transfer (CEST) contrast from MT asymmetry contrast by using the two-frequency RF irradiation technique. A further embodiment can isolate a narrow-frequency spectrum MT mechanism from a broad-frequency spectrum MT mechanism.

  • Patent number: 9588202
    Abstract: A method and system for providing an article of manufacture with increased longevity of hyperpolarized 1H signals (and other species) for NMR spectroscopy and MRI. The method involves providing a material including a molecular species susceptible of NMR spectroscopy, by providing parahydrogen (and other appropriate species) to disperse within the material/solvent to establish increased longevity of the NMR signals. The material can be in a solution with a surfactant and catalysts added to enhance the persistence of parahydrogen (or other species) in the form of enhanced solubility, microbubbles or micelles and resultant hydrogenation (or other species) of the material.
