FIG. 4.

(a) Plot of viscosity as a function of shear rate η($\dot{\gamma }$) for a 140 g/l lysozyme solution at (5, 20, and 50)  °C. This solution exhibits Newtonian behavior at all temperatures. (b) η($\dot{\gamma }$) for 480 g/l lysozyme solution at 5 °C. Data were acquired first (i) from high to low shear rate and then (ii) the reverse. Standard uncertainties of multiple measurements are reported.
