The properties of fluids confined in nanopores differ from the bulk mainly due to the solid-fluid interactions and the finite pore size. Such phenomena are of fundamental interest in physics but also relevant for practical applications. In our previous experiment we tried to study the freezing point depression and the structure of confined CO2 in ordered mesoporous SBA-15. NIMROD instrument is unique for these measurements due to its large Q-range that extends into a significant part of the small-angle region. From the SANS signal of the Bragg peaks we were able to monitor the gas-liquid equilibria along an adsorption isotherm. However, there were experimental difficulties that did not allow us to monitor gas-solid and/or liquid-solid equilibria and thus the freezing behaviour of confined CO2. It is anticipated that the proposed continuation will allow us to overcome these difficulties.
