# 🧪 pNIPAM microgel flow curves from glassy to jammed regimes (Ghosh et al. 2019, Fig. 3)

`dataset id: ghosh2019_fig3`

Steady-state flow curves of self-crosslinked, slightly charged, repulsive pNIPAM microgel suspensions digitized from Fig. 3 of Ghosh et al., Soft Matter 15, 1038-1052 (2019). Seven volume fractions from 0.46 to 0.881, spanning the fluid, glassy, and putatively jammed regimes. The paper combines experiment with a microscopic force-based theory of nonlinear yielding across all three regimes.
