Hydrodynamic Cavitation: A Promising Technology for Industrial-Scale Synthesis of Nanomaterials

Frontiers in Chemistry, 2020
One of the most challenging issues for the large-scale application of nanomaterials, especially nanocarbons, is the lack of industrial synthetic methods. Sonochemistry, which creates an extreme condition of high pressure and temperature, has been thereby
