Fractional distillation is a type of distillation which involves the separation of miscible liquids. The process involves repeated distillations and condensations and the mixture is usually separated into component parts. The separation happens when the mixture is heated at a certain temperature where fractions of the mixture start to vaporize.

End Mills—They look like drill bits but are sharpened on the sides as well as the ends. Held in an end mill holder, they are used to cut slots, pockets or surfaces. End mills are normally flat but "ball end" mills are also available that have a round end for leaving a radius in the corner of a pocket or a round-bottomed slot.

Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.
