A sonic reactor for transferring kinetic energy to a process fluid medium has a resonant element horizontally oriented and mounted to the two resonance units using two or more nodal support rings located at the nodal positions of the resonant element. The nodal support rings are adjustable in position relative to the resonant element and the resonance units to permit positioning of the rings directly at the nodal positions during operation, where, for example, adjustment may be required due to changes in the total mass attached to one or both free ends of the resonant unit. The sonic reactor has a grinding or mixing chamber mounted at one or both of the free ends of the resonant element.

A method for manufacturing a graphene composite film includes preparing a zeolite suspension containing zeolite nanocrystals with a concentration of 50-100 ppm and with a particle size of 50-80 nm. The zeolite suspension has a pH value of 11-13. A graphene oxide suspension containing graphene oxide with a concentration of 50-200 ppm is mixed with the zeolite suspension to form a composite solution. The composite solution is transferred into a 15 C. water bath when a color of the composite solution turns from brownish-yellow into deep brown. A surfactant is added into the composite solution in the 15 C. water bath. The composite solution is then sonicated for 5-30 minutes and removed out of the 15 C. water bath, with the color of the composite solution turning from deep brown into black. The composite solution is further processed to form a graphene composite film having not more than 5 layers.
