Figure 4

(a–c) Illustration for melting of ice inside a pore with a corresponding shift in T₂ distributions. Inherent pore/throat confinements and ice-induced confinements are also demonstrated in (a,b). (d) Transient ice melting rate; (e–g) Evolution of T_{2, min}, T_{2, max} and ΔT₂ = T_{2, max} − T_{2, min} during ice melting process, respectively.
