| description | Vibrational spectroscopy has been used to study fluids within nanopores to provide an insight into the unique phase characteristics of pore confined fluids. In particular the depression in the critical temperature of carbon dioxide, difluoromethane and ethane has been studied and the relationship between pore size and the extent of this depression has also been established. Finally, the change in composition has been assessed for two pore confined binary mixtures. These mixtures were carbon dioxide/acetonitrile and difluoromethane/tetrabutylammonium tetrafluoroborate. This has been studied in a range of pore sizes and at a range of mixture compositions. It was found that as the pore size decreased, the composition of the mixture shifted further away from that of the bulk. |
