  • Ball Milling Nanotubes :: News :: ChemistryViews

    Ester Vázquez and colleagues, Universidad de Castilla-La Mancha, Spain, report the use of a planetary retsch ball mill, which consisted of stainless steel balls within a grinding bowl, to cut and disperse single-walled nanotubes (SWNTs). Air, high rotational speeds, and long milling times led to partial or almost total destruction of SWNTs.
