Thermoporometry (and NMR cryoporometry), is fast gaining popularity for the characterisation of mesoporous materials before their wide arrayed applications. Among its numerous advantages over other techniques is its application to wet samples.

In this work, we have provided a framework to better provide structural details of porous materials. Specifically, a set of kernels containing a variable non-frozen layer (NFL) thickness and the impact of thermodynamic fluctuations on phase transitions have been implemented. These kernels have been applied to the serially-connected pore model (SCPM), which incorporates advanced melting and reveals disorder in, even, random pores, to characterise MCM-41 and SBA-15 materials.
