Effect of Ball Milling and Oxidation on Dispersibility and ...

2020-6-22  Ball milled multiwalled carbon nanotubes (BMWCNT) were subjected to covalent functionalization, in order to study the effect of ball milling on dispersion stability of BMWCNTs. BMWCNTs were thermally oxidized before covalent functionalization to reduce the probability of functional groups getting attached to amorphous carbon.

Flow behavior and syneresis of ball milled rice starch and ...

Syneresis diminished with increasing milling energy and starch concentration; it could be minimized (4% and 4.08 kJ/g) or completely eliminated (8% and 1.04 kJ/g). Significant correlations of Ri with consistency index and syneresis were found. Ball milling notably improved the suitability of starch as an ingredient in fluid or viscous foodstuffs.
