Afterward, it was quenched in air and then stored at room-temperature. The solid was dry ground in a planetary ball mill (Retsch PM4, Brinkman, NY) to obtain the median particle size of 17.0 μm (TTCP17). The TTCP17 was further ground in cyclohexane in the planetary ball mill for 24 h to obtain a median size of 5.0 μm (TTCP5).
