  • Patent number: 11981613
    Abstract: Disclosed are methods and systems for hydrogen isotope exchange of organic molecules that can be carried out with no alteration in the chemical structure of the organic molecules. Methods can be utilized to incorporate a particular hydrogen isotope on an organic molecule (e.g., deuteration or tritiation) or to remove a particular hydrogen isotope from an organic molecule (e.g., detritiation).
    Type: Grant

  • Patent number: 11289231
    Abstract: Radiation detectors and methods of using the radiation detectors that provide a route for surface decontamination during use are described. The detectors utilize light illumination of an internal surface during use. Light is in the longer UV-to-near-infrared spectra and desorbs contamination from internal surfaces of radiation detectors. The methods can be carried out while the detectors are in operation, preventing the appearance of the negative effects of radioactive and non-radioactive contamination during a detection regime and following a detection regime.

  • Patent number: 10016745
    Abstract: The present invention is directed to multifunctional nanomaterials for photothermal heating and catalytic applications. The present invention discloses a method of photothermally heating a solution. The present method also discloses a method of catalyzing a reaction. Both methods require a step of exposing a solution to at least one wavelength of the electromagnetic spectrum. A gold-iron oxide nanomaterial comprising an iron oxide substrate and discrete gold particles deposited on the substrate is also disclosed.
