TL;DR: In this paper, the melting and freezing of water in a series of mesoporous silica materials with a hexagonal arrangement of unidimensional cylindrical pores and narrow pore-size distribution was studied by differential scanning calorimetry (DSC).

TL;DR: It is concluded that D* represents a lower limit for first-order melting/freezing in the pores of well-characterized MCM-41 silica materials, including the one with 2.5 nm pores.

TL;DR: This work focuses on recent studies of the limits of freezing and melting of water in the cylindrical pores of ordered mesoporous silicas with pore diameters in the range of 2-10 nm, based on vapor sorption measurements, calorimetric studies, NMR spectroscopy and cryoporometry, and neutron diffraction studies.

TL;DR: The hydrogen bond interaction of pyridine with the silanol groups of the inner surfaces of MCM-41 and SBA-15 ordered mesoporous silica has been studied by a combination of solid-state NMR techniques as discussed by the authors.

TL;DR: In this paper, the freezing and melting of water in cylindrical pores of ordered mesoporous silica was studied by differential scanning calorimetry, showing that the enthalpy of melting and the hysteresis connected with the phase transition in the pores both vanish at a pore diameter ≅ 2.8 nm.
