Nanoporous glasses

During past decades, a relatively new method attracted much of attention of experimentalists, namely, the sol-gel method widely implemented in numerous scientific and industrial applications. Actually, it caused a breakthrough in material science it is worth mentioning that sol-gel routes are cmcial for synthesis of nanomaterials, and one of methods of the 21st century namely, commercial nanoporous glasses are readily available on the market just thanks to sol-gel technologies.

Cold chemical synthesis of nanoporous glasses by the sol-gel technique allows the embedding of temperature-sensitive clusters such as organic nanocrystals. Moreover, it often permits one to achieve larger densities of semiconductor nanocrystals than in diffusion-controlled growth.

Most of the earlier femtosecond RIKES studies were conducted to clarify the intermolecular vibrational and orientational dynamics in pure molecular hquids and binary mixtures (Kinoshita et al., 1996 Castner Maroncelli, 1998 Smith Meech, 2002 Zhong Fourkas, 2008 Shirota et al, 2009). Nowadays, femtosecond RIKES is also used to study the intermolecular vibrational dynamics, reorientation, and microscopic intermolecular interactions of complex condensed phases (Hunt et al., 2007 Farrer Fourkas, 2003) such as polymer liquids and solutions, microemulsions, aqueous protein films and solutions, and solvents in nanoporous glasses. As mentioned above, femtosecond RIKES has also been used to investigate ILs (Castner et al., 2007).

The l29Xe chemical shift - pore size relationship was extended to the mesopore region with a number of controlled pore glasses with pores in the 75-385 A range. There is a correlation of the pore diameter with the inverse of the chemical shift. For small pores there is markedly different behaviour with the switch occurring near the nanopore - mesopore transition at 10-20A.
