optical phenomena and antifrosting property on biomimetics slippery fluid infused antireflective films via layer by layer comparison with superhydrophobic and antireflective films
ACS Applied Materials & Interfaces, 2014Co-Authors: Kengo Manabe, Shingo Nishizawa, Kyu Hong Kyung, Seimei ShiratoriAbstract:Sophisticated material interfaces generated by natural life forms such as lotus leaves and Nepenthes pitcher plants have exceptional abilities to resolve challenges in wide areas of industry and medicine. The nano- and microstructures inspired by these natural materials can repel various liquids and form self-cleaning coatings. In particular, slippery liquid-infused surfaces are receiving remarkable interest as transparent, nonfouling, and antifrosting synthetic surfaces for solar cells and optical devices. Here we focus on the transparency of lubricant-infused texture on antireflective films fabricated by layer-by-layer self-assembly that decrease light scattering, which is important to maintain device properties. A slippery fluid-infused antireflective film composed of chitin nanofibers less than 50 nm in diameter prevented light scattering at the Long-Wavelength Side by Rayleigh scattering to achieve 97.2% transmittance. Moreover, films composed of the same materials demonstrated three different morpho...

Moreover, films composed of the same materials demonstrated three different morphologies: superhydrophilicity with antireflection, superhydrophobicity, and omniphobicity, mimicking the biological structures of moth eyes, lotus leaves, and pitcher plants, respectively. The effect of thermal changes on the ability of each film to prevent frost formation was investigated. The slippery fluid-infused antireflective film showed effective antifrosting behavior.

photocatalytic h2 evolution under visible light irradiation over band structure controlled cuin xzn2 1 x s2 solid solutions
Journal of Physical Chemistry B, 2005Co-Authors: Issei Tsuji, Hideki Kato, Hisayoshi Kobayashi, Akihiko KudoAbstract:(CuIn)xZn2(1-x)S2 solid solutions between a ZnS photocatalyst with a wide band gap and CuInS2 with a narrow band gap showed photocatalytic activities for H2 evolution from aqueous solutions containing sacrificial reagents SO32- and S2- under visible-light irradiation (λ ≥ 420 nm). Pt (0.5 wt %)-loaded (CuIn)0.09Zn1.82S2 with a 2.3-eV band gap showed the highest activity for H2 evolution, and the apparent quantum yield at 420 nm amounted to 12.5%. H2 evolved at a rate of 1.5 L h-1 m-2 under irradiation with a solar simulator (AM 1.5). Diffuse reflection and photoluminescence spectra of the solid solutions shifted monotonically to a Long Wavelength Side, as the ratio of CuInS2 to ZnS increased in the solid solutions. The photocatalytic H2 evolution depended on the composition as well as the photophysical properties. DFT calculations suggested that the visible-light response should be derived from the contribution of Cu 3d and S 3p orbitals to the valence band and that of In 5s5p and Zn 4s4p orbitals to the ...

photocatalytic h2 evolution reaction from aqueous solutions over band structure controlled agin xzn2 1 x s2 solid solution photocatalysts with visible light response and their surface nanostructures
Journal of the American Chemical Society, 2004Co-Authors: Issei Tsuji, Hideki Kato, Hisayoshi Kobayashi, Akihiko KudoAbstract:(AgIn)xZn2(1-x)S2 solid solutions between ZnS photocatalyst with a wide band gap and AgInS2 with a narrow band gap showed photocatalytic activities for H2 evolution from aqueous solutions containing sacrificial reagents, SO32- and S2-, under visible-light irradiation (λ ≥ 420 nm) even without Pt cocatalysts. Loading of the Pt cocatalysts improved the photocatalytic activity. Pt (3 wt %)-loaded (AgIn)0.22Zn1.56S2 with a 2.3 eV band gap showed the highest activity for H2 evolution, and the apparent quantum yield at 420 nm amounted to 20%. H2 gas evolved at a rate of 3.3 L m-2·h-1 under irradiation using a solar simulator (AM 1.5). The diffuse reflection and the photoluminescence spectra of the solid solutions shifted monotonically to a Long Wavelength Side as the ratio of AgInS2 to ZnS increased in the solid solutions. The photocatalytic H2 evolution depended on the compositions as well as the photophysical properties. The dependence of the photophysical and photocatalytic properties upon the composition wa...
