a
Mole fraction of the first compound wrt. The second compound in the eutectic phase (feu), as written.
b
Subscript refers to the onset, midpoint, and end of the glass transition.
c
Reduced glass transition temperature (Trg) calculated from Tg,o/Teu.
d
Kinetic fragility index (m) as defined in eqn (3).
e
Stability (tst) refers to the time elapsed in months (mos) before crystallization peaks appeared in each XRD pattern. Note each material was measured discontinuously for different lengths of time, and most did not fully crystallize within the experimental timescale.
f
Difficult to obtain due to Nic sublimation.
