Nanoporous thin-film waveguide resonance sensors with wavelength interrogation over a broad bandwidth

Qi Z-M, Zhang Z., Liu Q., Lu D., Institute of Electronics, Chinese Academy of Sciences, CN

Nanoporous dielectric film based leaky-mode waveguide resonance sensors have attracted considerable attention because of their interesting features [1-4]. Such sensors generally operate in the angular interrogation mode [1-3]. The first application of the wavelength interrogation [...]

Fabrication and assembly of nanowrinkle patterns on metallic surface: a nonlithography method for nano fabrication

Zhang Z., Guo C., Liu Q., National Center for Nanoscience and Technology, China, CN

Ordered periodic nanostructures have shown its great importance in both fundamental research and practical use. Motivated by wrinkles, which are ubiquitous in nature, artificial patterns with micro periods were fabricated in stiff/soft bilayer. Compare to [...]

Enhancement of in vitro Capillary Tube Formation by Substrate Nanotopography

Bettinger C.J., Zhang Z., Gerecht S., Borenstein J.T., Langer R., Massachusetts Institute of Technology, US

Controlling the morphology and function of cells using substrate nanotopography is a phenomenon that can be utilized in a variety of fields including tissue engineering and regenerative medicine. In this work, we explored the possibility [...]

Synthesis and Testing of Metal and Nitrogen Doped Nano-TiO2

Zhang Z., Darr J.A., University College London, UK

we have adopted a novel approach to the use of continuous hydrothermal flow system (CHFS) for the synthesis of various crystalline doped anatase TiO2 nano-ceramics with high surface area (ca. 280 m2g-1) system. Their photocatalytic [...]

Nano-Hydroxyapatite Coated Acetabular Cup Implant by Electrophoretic Deposition

Zhang H., Zhang Z., Krajewski J., Zhang H., Zhang Z., Xiao T.D., Reisner D., Inframat Corporation, US

A nanostructural hydroxyapatite (HA) coating was deposited to the porous Ti6Al4V hip cup implant using electrophoretic deposition (EPD) in order to improve the bonding strength between the implants and cells, fast healing, good resistance to [...]

Nano-granular FePt-Ag Composite Films- Its Magnetic and Magnetotransport Properties

Zhang Z., Suzuki T., Kang K., Omoto N., Toyota Technological Institute, JP

Ordered FePt films have a very high magnetic anisotropy [1]. By annealing FePt/Ag multilayer precursor films, isolated FePt nano particles have been obtained with high perpendicular magnetic anisotropy, which opens a window for ultra-high-density magnetic [...]
