Here, acidassisted ball milling synthesis was employed as a versatile method for the production of surfacemodified Prussian blue. With (CH3COO)2Fe being used as the raw material, the Prussian blue produced using ball milling synthesis was modified by the carboxyl functional group on its surface, which resulted in lower interstitial water ...

More recently, Song et al. described a new method to extract CNCs from raw cellulose by ball mill assisted acid hydrolysis. 43 The starting material was first ground in water using a ball mill at 1300 rpm, then treated with oxalic acid. Due to the relatively weak acidity of oxalic acid, ball milling was in this case employed as a pretreatment ...
