TiO2 was chosen because it is readily available as single crystals and can accept electrons easily.

TiO2因为是容易获取的单晶体并有易吸收电子的特性而被选中。

They found that these states were always below the TiO2 conduction band, which means that hot electrons from the quantum dot can transfer from the PbSe to the TiO2.

他们发现这些能级皆低于TiO2的传导带，这意味着从量子点放射出的热电子能够从PbSe传导到TiO2。

The TiO2 mixture was sprayed on 26, 000 feet of blue fabric, and HWKN principal Matthias Hollwich figures that by Sept. 8, when it's disassembled, "Wendy" will have digested the smog coughed up by the equivalent of 260 cars.
