The milling was carried out in a high energy planetary ball mill (Insmart Systems, India) with hardened steel medium and toluene as a process control agent (PCA) for 30 h at 300 rpm. High hardened steel vials and balls of 10 mm diameter with a ball to powder weight ratio (BPR) of 10:1were used for milling.
