Summary
In this article, the authors present experimental evidence supporting theoretical proposals suggesting that a jamming phase diagram could be used in order to describe attractive particle systems, where these attractive interactions play a role similar that to confining pressure. The fluid-to-solid transition of weakly attractive colloid particles is studied in detail, and the results conclude that they undergo a similar gelation behavior with increasing concentration and decreasing thermalization or stress. The authors thus claim that their results support the idea of a jamming phase diagram for attractive colloid particles, providing a unifying link between the glass transition, gelation, and aggregation.
