The points are determined from fitting the experimental data with Eqs. (3a,b) and (1), where T$_{g}$ ( d ) is obtained from τ ( T, d ) = 100 s, as shown in Fig. (5). The lines are fits using Eq. (4) and the relation T$_{g}$ − T$_{0}$ = E ln (100 /τ 0 ) = 50 . 6 K, as indicated in the text. 2 3 4 5 6 7 8 d (nm) 150 155 160 T 0  (K) 200 205 210 215 220 T g  (K) T$_{g}$(d) T$_{0}$(d) 0 2 4 6 8 d (nm) 50 100 150 200 250 T g  (K) T$_{g}$ bulk explored range T$_{g}$ bulk
