Editing Patchy particles

'''Patchy particles''' <ref>[http://dx.doi.org/10.1021/nl0493500 Zhenli Zhang and Sharon C. Glotzer "Self-Assembly of Patchy Particles", Nano Letters '''4''' pp. 1407-1413 (2004)]</ref> are models designed to keep pace with the rapid advances in the field of [[colloids]]. It is now possible to synthesise or fabricate tiny particles that have a variety of shapes, composition etc. In order to simulate these structures, there is a corresponding growth in the number of [[idealised models]] being developed and studied. With a view to classifying
these "patchy" models the idea of "anisotropy dimensions" has been put forward.

Anisotropy dimensions is a classification scheme for patchy particles <ref>[http://dx.doi.org/10.1038/nmat1949 Sharon C. Glotzer and  Michael J. Solomon "Anisotropy of building blocks and their assembly into complex structures",  Nature Materials '''6''' pp. 557-562 (2007)]</ref>.
The eight attributes are as follows:
====Surface coverage (A)====

====Aspect ratio (B)====

====Faceting (C)====

====Pattern quantisation (D)====
