The high porosity and large surface area make STFs likely candidates for use in some chemical applications. Photocatalysis using STFs of TiO2, a highly studied photocatalytic material, has been investigated experimentally for both gaseous and liquid phase reactants (Weinberger and Garber 1995; Suzuki et al. 2001). In the liquid phase work, % is found to be the major factor influencing reaction rates, with the particular shape of the STF nanowire playing a very minor role. Another study investigated the enhancement of surface area in microchannels by coating them with both CTFs and chiral STFs (Harris et al. 2000).

Have you ever been envious of people who seem to have no end of clever ideas, who are able to think quickly in any situation, or who seem to have flawless memories? Could it be that they're just born smarter or quicker than the rest of us? Or are there some secrets that they might know that we don't?
