Magnetic aerogels may prove useful for separating O2 from air. Considering the magnetic properties of O2 relative to those of the other principal components of air (N2, Ar), describe how this may be achieved. Why should aerogels be more suitable to this application than bulk (non-nanostructured) materials ... 

Another good example of the effects of aerogel nanostructure on the electrochemical behavior of materials is shown in the electroactive behavior of Mn02. As micrometer-thick films or deposits, Mn02 has exhibited a specific capacitance of 150 to 250 F/g (42-44). When synthesized as a nanoscale, ultra-thin coating, Mn02 can deliver a specific capacitance of over 700 F/g (45-47). In a study by Fischer et al. (48), a... 

Within the currently ubiquous nanoscience and nanotechnology efforts, the use of nanoparticles and nanostructured materials in catalysis appears as one of the most successful approaches [1]. It has been said that the most important drawback in nanoparticle appUcations is their tendency to aggregate and their dispersion in porous media has been shown to be a good way to prevent this. In this chapter a particularly interesting porous supporting material for nanoparticles, the aerogels, will be reviewed and their use in catalytical processes analyzed.

Abstract The present chapter is focused on describing the intimate link which exists between aerogels and thermal superinsulation. For long, this applied field has been considered as the most pronusing potential market for these nanostructured materials. Most likely this old vision will become reality in the near future. 

Porous chalcogenide aerogels is another broad class of non-oxidic framework that prepared by template-free routes [71-73]. These materials possess a continuous nanostructured chalcogenide framework that is penetrated by a random network of nanopore channels. Because these high surface area structures are random and not exhibit long-range pore periodicity, such systems are outside of the scope of this review and will not be covered further.
