Energy dissipation per cycle was calculated from hysteresis curves, and plotted against frequency. (A) Comparisons of Control (n = 3), Pre48CX (n = 3), Pre24CX (n = 3) show decreased energy dissipation in GCX cross-linked gels. (B) Comparisons of Control, CCX (n = 4), and Post24CX (n = 2) show increased energy dissipation from Post24CX gels, and peak shift to lower transition frequency. Key: ●, Control; ■, Pre48CX; ◆, Pre24CX; ▲, CCX; +, Post24CX.
