  • Patent number: 10720269
    Abstract: The present invention is directed to the syntheses of superparamagnetic nanoparticles and the incorporation of the nanoparticles as the magnetic component to form a strongly magnetic nanocomposite. The superparamagnetic nanoparticles possess no hysteresis and are too small to support eddy currents. The invention uses a ligand exchange procedure to produce aminated nanoparticles that are then cross-linked using epoxy chemistry. The result is a magnetic nanoparticle component that is covalently linked and well separated. By using this ‘matrix-free’ approach, it is possible to substantially increase the magnetic nanoparticle fraction, while still maintaining good separation, leading to a superparamagnetic nanocomposite with strong magnetic properties and low magnetic losses.

  • Patent number: 10711188
    Abstract: In certain embodiments, a first semiconductor material is vaporized to generate a vapor phase condensate. The vapor phase condensate is allowed to form nanoparticles. The nanoparticles are annealed to yield nanoparticles or cores. The cores are overcoated by introducing a solution containing second semiconductor material precursors in a coordinating solvent into a suspension of cores at a desired elevated temperature and mixing for a period of time sufficient to cause diffusion of the shell into the core. The diffusion of the shell into the core causes the quantum dots to exhibit a broadened optical emission. The produced quantum dots may be incorporated into a quantum dot based radiation source.
