We describe physical-organic studies of singlet oxygen generation and transport into an aqueous solution supported on superhydrophobic surfaces on which silicon-phthalocyanine (Pc) particles are immobilized. Singlet oxygen ((1)O2) was trapped by a water-soluble anthracene compound and monitored in situ using a UV-vis spectrometer. When oxygen flows through the porous superhydrophobic surface, s...

a r t i c l e i n f o The composite film of carbon nanotubes and silicon carbide nanowires was synthesized directly on the silicon substrate by the catalyst-assisted method. The carbon nanotubes crimped together decorated with silicon carbide nanowires covering the whole substrate. The appropriate amount of aluminum powders is a crucial factor to achieve the composite film. The composite film e...

Correction for 'Design of a robust superhydrophobic surface: thermodynamic and kinetic analysis'

This thesis presents a series of three related studies with the aim of developing a surface that promotes robust dropwise condensation. Due to their remarkably low droplet adhesion, superhydrophobic surfaces were investigated for application to dropwise condensation. Although precise model superhydrophobic surfaces were necessary to gain insight into these phenomena, it was recognized that wide...

A superhydrophobic surface is coated on the surface of a cloth by MTCS (methyltrichlorosilane) nanoparticles and then, it is modified by SiO2–m–FTCS (1H,1H,2H,2H-Perfluorododecyltrichlorosilane) nanoparticles. This surface is characterized by SEM(scanning electron microscopy), and FT-IR (Fourier transform-infrared microscopy) and also its contact angle is investigated in various conditions and ...

Micromolding surface-initiated polymerization enables the fabrication of polymer coatings that reproduce the microscale surface topography of superhydrophobic leaves onto solid supports. Here, the surfaces of superhydrophobic leaves from Trifolium repens and Aristolochia esperanzae are molded and reproduced as the topography of a partially fluorinated polymer coating through the surface-initiat...

Metal copper mesh with superhydrophobic and superoleophilic surface had been successfully fabricated via a facile solution-immersion process. The hierarchical structure was prepared on the commercial copper mesh surface by etching with the nitric acid. After being modified by 1-hexadecanethiol (HDT), the as-prepared mesh indicated both superhydrophobic and superoleophilic property simultaneousl...

When a water droplet rolls easily, retaining a nearly perfect spherical shape on a surface that remains essentially dry, such a surface is super-repellent or superhydrophobic. Common superhydrophobic materials include many plant leaves, duck feathers, and glass surfaces coated by black soot dispersed from a lighted candle (see Fig. 1a,b). By convention, for a surface to be superhydrophobic, the...

We demonstrate here that water can be efficiently wet and pumped through superhydrophobic aligned multiwalled nanotube membranes by application of a small positive dc bias. At a critical bias ( approximately 1.7 V), with the membrane acting as anode, there is an abrupt transition from a superhydrophobic to hydrophilic state. Interestingly, this phenomenon is strongly polarity dependent; for a n...
