The jamming phase diagram provides a useful framework and set of parameters to map clogging, intermittency, and flow in crosslinking alginate. However, the analogy between flow dynamics and thermodynamics is not complete. In particular, the region of intermittent flow has no analog in the colloidal phases. Still, borrowing this conceptual framework may provide useful insights when examining other crosslinking polymers in flow. Alternate axes could incorporate channel geometry, to inform bioprinting applications, in which nozzles are usually symmetric and coaxial . Further nuance and complexity could be incorporated by investigating crosslinking reaction rates. Reaction rates become very important in biomedical contexts, as in the growth and ablation of blood clots in thromboembolism . Clot formation represents an enzyme catalyzed reaction in which thrombin both catalyzes fibrinogen polymerization and crosslinks the resulting fibrin polymers into a fibrin mat . Interestingly, a range of physiologically relevant wall shear rates and stresses overlap with the range observed in our experiments .
