    Summary:One-dimensional growth of copper (Cu) is observed when Cu is deposited on cuprous iodide (CuI) films at elevated temperatures by thermal evaporation in high vacuum. The morphology, crystallinity, and chemical composition were examined for the samples using scanning electron microscopy, transmission electron microscopy, X-ray diffraction, energy-dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy. Straight single-crystalline Cu nanowires can be formed on polycrystalline CuI films at 200 degrees C. Anisotropic growth of Cu in one-dimension was promoted by enhancing grain growth and continuity of CuI films. At a lower temperature of 100 degrees C, fuzzy branching nanowires were grown on the surface of CuI films, enabling to simply fabricate a self-supporting, highly porous film of Cu. It is revealed that a Cul film serves as a functional substrate to synthesize nanostructured Cu at low temperatures. Possible growth processes are proposed to explain the observed morphology evolution of Cu with respect to synthesis conditions. The characterization of water wettability showed that the hydrophobicity was remarkably enhanced due to the formation of nanostructured Cu on the CuI films. (c) 2017 Elsevier Ltd.

    Summary:Dissipative structures are macroscopic or even larger ordered structures that emerge under conditions far from thermodynamic equilibrium. In contrast, molecular self-assembly has been investigated near at the thermodynamic equilibrium, which provides basically smaller, nano-to-micron sized structures. In terms of the formation principles, there exists an essential gap between the dissipative structures and molecular self-assemblies. To fill this gap, molecular self-assembly of light-reducible organic-inorganic ion pairs was investigated under far-from-equilibrium conditions. When solid films of tetraalkylammonium hexafluorophosphate were immersed in aqueous Au(OH)4(-) and immediately photoirradiated, gold nanowires are formed at the solid-aqueous interface. On the other hand, such nanowires were not formed when the photoirradiation was conducted for the specimens after a prolonged immersion period of 60 min. These observations indicate spontaneous growth of dissipative nanofibrous self-assemblies consisting of light-reducible ion pairs [tetraalkylammonium ion][Au(OH)4(-) at the interface and their photoreduction to give developed nanowires. These nanowires are not available by the photoreduction of Au(OH)4(-) ions under conditions near at the thermodynamic equilibrium. A picture for the dissipative nanostructures is obtained: the formation of amphiphilic light-reducible nanowire structures is based on the static self-assembly near at the thermodynamic equilibrium, whereas their spontaneous, anisotropic growth from the interface to the aqueous phase is directed by dynamic, dissipative self-assembly phenomena under the far-from-equilibrium conditions. Thus, the both elements of dissipative self-assembly (dynamic) and static molecular self-assembly fuse together at the nanoscale, which is an essential feature of the dissipative nanostructures.

    Summary:A novel synthetic technique for gold nanosheets and hollow gold nanocapsules is developed. When aqueous HAuCl4 (pH 10, 1 mL) layered on C4mimPF6 (1-butyl-3-methylimidazolium hexafluorophosphate, 1 mL) was illuminated vertically with a super high pressure mercury lamp, gold nanosheets with thickness of ca. 30 nm are formed. The gold nanosheets are face-centered cubic (fee) single crystals with an atomically flat (111) surface as determined by electron diffraction analysis. Photoreduction of Au(III) ions did not proceed when aqueous HAuCl4 solution (pH 10) was photoirradiated in the absence of ionic liquid. Therefore, photoreduction occurs at the ionic liquid/water interface, and photo-excited C 4mimPF6 molecules may act as sacrificial electron donors to reduce Au(OH)4- ions. We also conducted the photoreduction by using microdroplets of C4mimPF6 in water. Ultrathin gold nanosheets with thickness of ca. 10 nm are obtained by photoilluminating mixture of C4mimPF6 (1 mL) and aqueous HAuCl4 (pH 10, 1 mL) under vigorous stirring. To our surprise, in the TEM observation of ultrathin gold nanosheets, moiré fringes are observed for overlapped portions. The observation confirms that the ultrathin gold nanosheets are single crystalline with homogeneous thickness. On the other hand, when a mixture of C4mimPF6 (1.8 mL) and aqueous HAuCl4 (pH 10, 0.2 mL) was illuminated under vigorously stirring, hollow gold microspheres with diameter less than 3 μm are obtained. In this case, water microdroplets in C4mimPF6 seem to act as template for the formation of hollow gold spheres.
