A method and a system for producing nanoparticles. The method includes obtaining a foil covered screw by wrapping a foil around an externally threaded section of an outer surface of a screw, placing the foil between an internally threaded section of an inner surface of a nut and the externally threaded section of the outer surface of the screw by screwing the foil covered screw into the nut, and grinding the foil between the internally threaded section of the inner surface of the nut and the externally threaded section of the outer surface of the screw by vibrating one of the nut and the foil covered screw along a first axis. The system includes a foil covered screw, a nut with an internally threaded section, and an ultrasound transducer. The nut and the screw are configured to grind the foil between the internally threaded section of the nut and the externally threaded section of the screw responsive to one of the nut and the screw vibrating along the first axis.
