The Quest for Nanotechnology and the Evolution of Wet and

Steam can be provided to a jet mill at high pressures compared to air. At higher grinding pressures, higher jet speeds can be attained. For example, at 100 BAR absolute, the jet speed exceeds 1200 m/s, compared to 600 m/s when using air, the kinetic energy in the mill is substantially higher with a proportional increase in capacity.

Ball milling: a green technology for the preparation and

Milling was then performed in 80% ethanol for 30–120 minutes using a high-energy ball mill. The mechanical treatment resulted in a reduction of the fibre length and diameter, probably due to degradation of the cellulose amorphous regions. Fibrillation was helped by the wet environment, which facilitated the intra-fibre swelling.
