Colloidal systems glasses gelation

J Glasses in Colloidal Systems Attractive Interactions and Gelation... 

Finally, several routes to gelation have been presented systems with arrested spinodal decomposition and without states of fluid-fluid coexistence, systems where the fluid-fluid separation is arrested only at very low temperatures (but can be observed at higher ones), and systems where the fluid-fluid transition is suppressed. Whereas the former probably applies to most experiments with short-range attractions (colloid-polymer mixtures), the second mechanism is found when longer-ranged attractions are present (particularly in the case of proteins). The latter has been extensively studied by computer simulations since it allows access to the attractive glass transition from homogeneous fluid states and is the main objective of the present work.
