Previous work had shown that titanium dioxide could be rendered superhydrophilic (intensely attractive to water) upon exposure to ultraviolet light—a hindrance under extremely foggy conditions, as water would stick to the mesh rather than trickle into the cistern.

之前的研究表明， 二氧化在暴露于紫外线后会变得超亲水（对水有强烈的吸引力）——这在极度多雾的条件下会造成阻碍，因为水会粘附在网上而不是滴入水箱。
