Light-induced amphiphilic surfaces
Rong Wang,Kazuhito Hashimoto,Akira Fujishima,Makota Chikuni,Eiichi Kojima,Atsushi Kitamura,Mitsuhide Shimohigoshi,Toshiya Watanabe +7 more
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.

Koichi Awazu,Makoto Fujimaki,Carsten Rockstuhl,Junji Tominaga,Hirotaka Murakami,Yoshimichi Ohki,Naoya Yoshida,Toshiya Watanabe +7 more
TL;DR: The plasmonic photocatalysis will be of use as a high performance photocatalyst in nearly all current applications but will beof particular importance for applications in locations of minimal light exposure.
Effects of the Surface Roughness on Sliding Angles of Water Droplets on Superhydrophobic Surfaces
TL;DR: In this paper, the relationship between sliding angles and contact angles on superhydrophobic surfaces with roughness was investigated and an equation was derived to describe the relationship of sliding angle and contact angle.

Effects of Surface Structure on the Hydrophobicity and Sliding Behavior of Water Droplets
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.

Detection of active oxidative species in TiO2 photocatalysis using the fluorescence technique
TL;DR: In this article, the effect of light intensity on the generation efficiency of active oxidative species was examined by measuring the fluorescence derived by the reaction with either coumarin or terephthalic acid.
