surfactant assisted high energy ball mill
Low-Cost Synthesis of Highly Luminescent Colloidal Lead
High-energy ball milling is a type of mechanical grinding of materials. This process can be conducted in a dry (without solvents) or wet (with solvents) fashion. Laboratory-scale ball milling (5−100 mL scale) is a batch process whereas industrial ball mills can be operated in a continuous mode thus offering a very high synthesis throughput.
