TL;DR: In this paper, the photogeneration of a highly amphiphilic (both hydrophilic and oleophilic) titanium dioxide surface was reported, and the unique character of this surface was ascribed to the microstructured composition of hydrophilicity of the phases, produced by ultraviolet irradiation.

TL;DR: In this paper, the progress of the scientific research on TiO2 photocatalysis as well as its industrial applications are reviewed, and future prospects of this field mainly based on the present authors' work.

TL;DR: In this paper, the same absorbed photon number, 1.4 × 1014 quanta·cm-2·s-1, of visible (Vis) or ultraviolet (UV) light was evaluated by the decomposition of gaseous 2-propanol (IPA) powders with low nitrogen concentrations (< 0.02) and showed that the isolated narrow band formed above the valence band is responsible for the Vis light response in the present nitrogen doped TiO2.

TL;DR: The magnetization in the ferrimagnetic region below 16 kelvin was substantially increased after illumination and could be restored almost to its original level by thermal treatment and these effects are thought to be caused by an internal photochemical redox reaction.

TL;DR: In this article, the sliding behavior of water droplets over pillarlike and groove structures was investigated and a proper design of the surface with respect to shape and extent of the three-phase line is more effective than the increase of contact angles merely by decreasing the solid−water contact area.
