Figure 5
Diffraction patterns from a ferritin crystal recorded during the measurements reported in Fig. 4(a). The patterns shown are the first to be recorded at each temperature in the series where (a) corresponds to 100 K, (b) to 160 K and (c) to 180 K. (d) represents the first pattern at 100 K recorded upon cooling from 180 K. Irreversible ice formation is seen at 180 K. |
