Comminution - an overview | ScienceDirect Topics
Comminution (break-down) techniques. Comminution is the reduction of solid material particle size by fracture via grinding, milling, or similar processes. Comminution techniques are usually employed to produce particulate nanomaterials (e.g., powder) from larger-sized or bulk materials.

Clast comminution during pyroclastic density current ...
Volcanic clasts within pyroclastic density currents (PDCs) tend to be more rounded than those in fall deposits. This rounding reflects degrees of comminution during transport, which produces an increase in fine-grained ash with distance from source (Manga, M., Patel, A., Dufek., J. 2011. Bull Volcanol 73: 321-333). The amount of ash produced due to comminution can potentially affect runout ...
Degree of polymerization - Wikipedia
The degree of polymerization, or DP, is the number of monomeric units in a macromolecule or polymer or oligomer molecule.. For a homopolymer, there is only one type of monomeric unit and the number-average degree of polymerization is given by ≡ =, where M n is the number-average molecular weight and M 0 is the molecular weight of the monomer unit. For most industrial purposes, degrees of ...
