This proposal aims to investigate the dynamics of the melting transition in H2O and CO2 when confined in a vycor (SiO2) matrix. The field of fluids in confined geometries is currently of great interest, as it has implications in physical, chemical and biological systems. The purpose of this investigation is to investigate the dynamics of the bulk melting transition of confined water and confined CO2, in an attempt to shed light on the origins of an anomalous peak seen in dielectric spectroscopy and positron annihilation measurements in confined H2O and CO2.The effect seems to be ¿universal¿ and in many ways our data is similar to that of the differential scanning calorimetry data of the glass transition in glycerol. The key goal for our investigation is to unpick the density of states to understand what modes of the system are responsible and why no signature is seen in Cp.
