Size reduction mills are used in the pharmaceutical industry to increase surface area, improve formulation dissolution and maintain a consistent average particle size distribution for tablets and capsules. Materials may be elements, compounds or mixtures.ġ9.2.9.3 Caffeine, extraction with supercritical carbon dioxide, critical point

The number of positively charged protons is equal to the number of negatively charged electrons in a neutral atom, and determines all the chemical properties of an atom. Matter is composed of atoms, which, in turn, contain protons and neutrons in a nucleus, and electrons outside the nucleus.
