Ultrasonic horns having improved longevity and simplified manufacturing approaches that can be more easily adapted to ultrasonic reactor chambers or batch processing containers. The ultrasonic horn designs increase the uniformity and intensity of acoustic energy radiated into a liquid medium and thus better correspond to the requirements of a particular sonochemical or sonomechanical process. The ultrasonic horns do not require a specific number of cylindrical sections and allow for various lengths and profiles of variable-diameter sections. The ultrasonic horns also reduce stress in the material of the ultrasonic horns and therefore extend longevity.

A method for synthesizing nanoparticles by sonofragmentation includes dispersing ultra-thin substrate units in a solvent chosen for suitability for sonofragmentation of the substrate, forming a suspension; ultrasonicating the suspension for a length of time sufficient to fragment the substrate into nanoparticles that are dispersed in the solvent; and evaporating the solvent. Solvent exchange with a second solvent may be performed. The synthesized nanoparticles are highly crystalline and monodispersed. The surface of the synthesized nanoparticles may be functionalized by choosing the solvents according to chemistry related to the intended surface functionalization of the synthesized nanoparticles, by adding surfactants to one or more of the solvents, and/or by performing ligand exchange or chemical modification to replace surface-bonded solvent or surfactant molecules with other functional groups to produce nanoparticles having the desired surface functionalization.
