Latest Patents

Yujuan He holds a patent for a print head designed for printing nanomaterials. The patent describes a print head comprising nested chambers for in-situ reactant formation. The first chamber contains a first nozzle, while the second chamber houses a second nozzle, both of which are substantially coaxial. A susceptor, which converts electromagnetic energy to heat, is located within the first chamber. This susceptor features openings that extend between its upper and lower portions. It can be heated through induction or optical heating to vaporize a precursor substance. The resulting vapor can react with a reactive gas in the first chamber or expand into the second chamber, where it may form nanoparticles. This technology allows for the creation of patterned films on two-dimensional or three-dimensional surfaces.
