    Abstract: A print head comprising nested chambers for in-situ reactant formation is disclosed. The print head comprises a first chamber nested within a second chamber. The first chamber comprises a first nozzle, the second chamber comprises a second nozzle. The first nozzle is substantially coaxial with the second nozzle. A susceptor to convert electromagnetic energy to heat is within the first chamber. The susceptor comprises one or more openings extending between the upper portion and the lower portion. The susceptor may be heated by induction heating or by optical heating to vaporize a precursor substance within the first chamber. The vapor may react with a reactive gas flowing through the first chamber or expand through a nozzle into a second chamber where the vapor may react with the reactive gas, forming nanoparticles. Patterned films may be written onto a two-dimensional or three-dimensional surfaces.

    Abstract: Apparatuses and methods for synthesizing nanoparticles are provided. Methods for synthesizing nanoparticles are provided comprising mixing at least two solutions comprising the components of the nanoparticles within a micromixer; exposing the resultant mixed, unreacted, azeotropic solution to ultrasound; and collecting the generated nanoparticles. Apparatuses are also provided for synthesizing nanoparticles comprising a micromixer in fluid connection with a continuous reactor comprising at least one inlet, at least one outlet, and an ultrasound horn oriented such that the acoustic energy is transferred to the fluid within the continuous reactor.
