ABSTRACT:
An apparatus and method are disclosed for producing nanoparticles in a dense fluid medium. The method is based on the formation of nanoparticles from nanoparticle precursors in a dense fluid medium in which a plasma discharge is created between electrodes submerged in the dense fluid medium. The electrodes define a plasma discharge zone between opposing electrode discharge faces and further define an internal cavitation zone into which a cavitation gas is released, creating bubbles in the dense fluid medium. The result is the efficient production of nanoparticles using a high-frequency, high-voltage electric field to react dense-phase precursors in an atmospheric pressure, low temperature environment.
