Shorter o-Ps lifetime and lower glass transition temperature due to preservation of the state in dilute solutions were observed for ultrathin polystyrene films by Ata et al. [7].
It is noteworthy that our results for Nafion® are qualitatively similar to those of Ata et al.

In light of this, lots of research have been attempted so as to solve these problems: the group of Hoffmann et al has ever doped various elements into the TiO2 [8], Bahnemann et al group reported to make TiO2 couple with different band-gap semiconductors [9].
