Patchy particles [1] 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.
Taxonomy: anisotropy dimensions
Anisotropy dimensions is a classification scheme for patchy particles [2]. The eight attributes are as follows:
Surface coverage (A)
Aspect ratio (B)
Faceting (C)
Pattern quantisation (D)
Branching (E)
Chemical ordering (F)
Shape gradient (G)
Roughness (H)
Models
- Bol model of water
- Dahl and Andersen model of water
- Kern and Frenkel patchy model
- Modulated patchy Lennard-Jones model
- Smith and Nezbeda associated fluid model
- Laponite
