Fabrication of the Two-Dimensional Nanostructure on Dye-Doped Polymer Film by Multiple Holographic Recording

Huang B-Y, Yu K-Y, Kuo C-T, National Sun Yat-San University, TW

we demonstrate that the 2D-SRGs structures can be fabricated easier and faster by using pulsed laser with two-stage instantaneous writing. The structures of 2D-SRGs fabricated with the interface of nematic liquid crystals become more perfect [...]

Broadband infrared reflecting thin films inspired by quasi-ordered photonic structures in squid tissue

Rotstein R., Sweeney A.M., Holt A., Stucky G.D., Morse D.E., UCSB, US

We present a novel synthetic approach to replicating the optical properties of quasi-ordered photonic structures in the silver-colored tissue in Loliginid squid. The squid system exhibits broadband reflectance in the visible spectrum. Rod-like polystyrene particles, [...]

Synthesis and Characterization of Poly(urethane-imide)-POSS nanocomposites

Gnanasekaran D., Reddy B.S.R., Central Leather Research Institute, IN

A series of Poly(imide-urethane)-POSS membranes were synthesized through the condensation reaction of anhydride terminated prepoly(imide) (API) and isocyanate terminated prepoly(urethane)POSS (IPU) by varying the amount of API and IPU . The API was synthesized by [...]

Nanoscale tailoring of the surface properties of biomedical devices by layer-by-layer technique

Chiono V., Carmagnola I., Boccafoschi F., Gentile P., Tonda-Turo C., Del Pilar Camacho Leal M., Ballarini M., Ciardelli G., Politecnico di Torino, IT

The layer-by-layer (LbL) technique is a versatile solvent-free process allowing the coating of surfaces with uniform ultrathin multilayered films to tailor surface properties and structure at the nanoscale. LbL approach is a promising tool to [...]

Cell adhesion behaviors on polyethylene terephthalate surface modified by surface-wave plasma-initiated graft polymerization

Nina A., Ishizaki T., Saito N., National Institute of Advanced Industrial Science and Technology (AIST), JP

For better performance in biomedical applications, the PET surface still needs to be improved by functionalization, particularly controlling the hydrophilicity. In order to impart hydrophilicity to the PET surface, we tried to introduce acrylic acid [...]

Stable Superhydrophobic TiO2-based Nanobelt Films with Controllable Transparence and Adhesion

Laiand Y.K., Gong D.G., Gong J.J., Tang Y.X., Gong D.G., Gong J.J., Lin C.J., Chen Z., Xiamen University, CN

Therefore, it is a challenge to develop more convenient methods to quickly deposit titanate nanostructured powder on various substrates to construct superhydrophobic films. In this work, stable TiO2-based nanobelt/fluoroalkylsilane (TNB/FAS) hybrid solution were synthesized by [...]

Upconverting Nanophosphors for High Temperature Sensing Applications

Guo X., Zhao H., Song H., Chen Q., Li K.K., Zou Y.K., Jiang H., Combs C., Narayanaswamy V., Clemens N., Boston Applied Technologies, Inc., US

In this work, a unique upconverting thermographic phosphor technique was developed for overcoming the difficulties encountered currently in the down-conversion route. Upconverting nanopowders of rare earths doped refractory oxides were synthesized through a wet chemical [...]

A comparative study over the photocatalytic activity of nanostructured TiO2 layers for air purifiers

Diamanti M.V., Del Curto B., Pedeferri MP., Cigada A., Politecnico di Milano, IT

The research presents an investigation over the efficiency of nanostructured TiO2 films as photocatalysts either in air purification systems or to be integrated in light devices, based on the exploitation of UV or Vis irradiation [...]

On-demand release of corrosion-inhibiting molecules from layerd double hydroxide film formed on magnesium alloy

Ishizaki T., Teshima K., Saito N., National Institute of Advanced Industrial Science and Technology (AIST), JP

Magnesium is one of the lightest engineering materials. Thus, it is expected that magnesium and its alloys are applied to aerospace, aircraft, automobile, and railway. However, they have a defect which is extremely low corrosion [...]

Electrodeposition of Rhenium-Tin Nanowires

Naor-Pomerantz A., Eliaz N., Gileadi E., Tel Aviv University, IL

Rhenium (Re) is a refractory metal which exhibits an extraordinary combination of properties. Thus, nanowires and other nanostructures of Re-alloys may possess unique properties resulting from both Re chemistry and the nanometer scale, and become [...]
