(a) Viscoelasticity plot of GG samples sonicated (at %) for different periods of time (0, 1, and 5 min). (b) Viscoelasticity curves of GG samples, with (red symbols) and without borax (black symbols): for comparison, the flow curves recorded for GG are also reported ( = full symbols, = empty symbols; %, °C).
