Melting and freezing of water in cylindrical silica nanopores.
Freezing and melting of H(2)O and D(2)O in the cylindrical pores of well-characterized MCM-41 silica materials (pore diameters from 2.5 to 4.4 nm) was studied by differential scanning calorimetry (DSC) and (1)H NMR cryoporometry. Well-resolved DSC melting and freezing peaks were obtained for pore diameters down to 3.0 nm, but not in 2.5 nm pores. The pore size dependence of the melting point de...
متن کاملNot freezing water in the lamellar system of chloroplasts.
In the course of small angle X-ray scattering analyses K r e u t z and W e b e r 1 observed that the particles of a soluble protein preparation derived from the lamellar system of chloroplasts by treatment with formic acid, exhibited an unusual high water content of 75 per cent. Viscosimetric investigation by M e n k e and R u p p e l 2 with a preparation obtained by a somewhat modified procedu...
متن کاملMelting-Freezing Transition of Monolayer Water Confined by Phosphorene Plates.
The two-dimensional material phosphorene has become a focus of the scientific community recently. On the basis of molecular dynamics simulations, we utilize phosphorene as a model material to study the behavior of water molecules confined by two phosphorene plates with nonflat surfaces. As the relative position of the two plates changes, the water molecules first stay in a melting process at 23...
متن کاملThermodynamics of freezing and melting
Although the freezing of liquids and melting of crystals are fundamental for many areas of the sciences, even simple properties like the temperature-pressure relation along the melting line cannot be predicted today. Here we present a theory in which properties of the coexisting crystal and liquid phases at a single thermodynamic state point provide the basis for calculating the pressure, densi...
متن کاملPre-freezing and Pre-melting
When attempts are made to interpret the solid-liquid transition in terms of molecular structure, highly significant information can emerge from phemomena of pre-melting and pre-freezing. Empirically, on approaching the transition between solid and liquid, characteristic parameters of the phase under examination may show an accelerated rate of change, in the sense of a premonition of the change ...
