Fig. 5 (a) Thermogravimetric analysis and (b)
differential scanning calorimetry for unmilled NiO
(black line), NiO milled with carbon (black
line + triangle symbols), NiO milled with methanol
(black line + circle symbols), and NiO milled with
Vertrel XF (black line + square symbols). In the
differential scanning calorimetry traces, exothermic
events produce an upward peak.
