Sam Pedersen recently presented his work on converting red phosphorus to black phosphorus at MRS. Black phosphorus has the potential to be an important optoelectronic material; however, it is currently expensive to manufacture. Sam has shown high energy ball milling is a viable synthesis route for converting inexpensive red phosphorus into black phosphorus. In his talk, he discussed how the milling kinetics can be used to scale-up black phosphorus production to a commercial scale.
