Similarly 50% weight loss occurred at 331 °C for CNF, which is much higher than the acid processed samples (260 °C). Thus it is inferred that CNF produced by the ball milling method retained the thermal stability of the native cellulose. Moreover, the acid hydrolysed CNC sample has the highest residual mass at 600 °C.

Synthesis of Nanomaterials by High Energy Ball Milling

Jan 15, 2020· •Nano Fe 2 O 3 and N-doped graphene was prepared via a one-step ball milling method. •The maximum power density of Fe-N-G in MFC was 390% of that of pristine graphite. •Active sites like nano Fe2O3, pyridinic N and Fe-N groups were formed in Fe-N-G. •The improvement of Fe-N-G was due to full exposure of active sites on graphene.

Therefore, a secondary ball milling method was introduced to obtain a fine and uniformly distributed γ(Ni, Fe) phase. Phase development of mechanical alloyed powders was investigated by X-ray diffraction. The results show that the formation of the γ(Ni, Fe) phase was found after 18 h of a pre-milling procedure.
