  • Patent number: 10543534
    Abstract: Systems, methods, and devices are disclosed for producing quantum particles (e.g., quantum dots) having a uniform size by vaporization of molten precursor droplets. More particularly, the present technology produces quantum dots by melting or liquefying solid and substantially pure precursor materials followed by production of uniformly sized droplets of molten precursor by use of a droplet maker into a microwave generated plasma torch.

  • Patent number: 10477665
    Abstract: A microwave plasma torch providing two laminar flows is described. Two laminar flows are created using a set of at least three concentric, staggered dielectric tubes connected to a pressurized gas source. An inner laminar flow entrains injected particles entering the plasma. An outer laminar flow creates a sheath around the plasma and prevents it from attaching to the walls of the plasma torch. The entry point of the gas source is designed to ensure laminar flow for both the entrainment of the particles and for the shielding of the plasma plume. The uniform processing conditions results in uniform particles and a homogenous materials distribution. This enables a final product with improved thermal properties, improved corrosion and wear resistance and a higher tolerance to interface stresses. The microwave plasma torch can be used for producing nanomaterial powder and for spray coating materials onto various substrates.
