mm, and ground in a ball mill. Hydrophilic and polar substances were extracted from 300 mg of a soil sample using methanol prior to microwaveassisted extraction for 15 min and centrifugation for 15 min at 3000 rpm. A 5 mL volume was then evaporated to 1 mL, diluted in ultrapure water (UP), and acidified to pH 2 (HCl). Solid phase

A ball mill is a type of grinder used to grind and blend bulk material into QDs/nanosize using different sized balls. The working principle is simple; impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell. The nanostructure size can be varied by varying the number and size of ...
