The nanosphere lithography (NSL) method can be developed to deposit the Au-Ag triangle hexagonal nanoparticle arrays for the generation of localized surface plasmon resonance. Previously, we have found that the parameters used to form the NSL masks and the physical methods required to deposit the Au-Ag thin films had large effects on the geometry properties of the nanoparticle arrays. Consideri...

Simultaneously increasing the strength and ductility of hot work die steels is significant interest for broad applications. The in-situ development a nano-phase in promising method achieving this objective. However, little success has been reported so far. In study, trace amounts TiC nanoparticles were successfully introduced into high-Cr steel (HHD) through an innovative using nano-TiC/Al mast...

The effective large-scale Hamiltonian of a planar system of nano-loops in a weakly excited flux-closed magnetized state has been constructed by means of a perturbative technique based on micromagnetic theory. The Hamiltonian is written by means of two classes of collective variables: the continuous soft spins and discrete vorticity charges. Analytical and numerical calculations of the inter-loo...

We report a simple method to fabricate nano-porous tantalum oxide films via anodization with Ta foils as the anode at room temperature. A mixture of ethylene glycol, phosphoric acid, NH4F and H2O was used as the electrolyte where the nano-porous tantalum oxide could be synthesized by anodizing a tantalum foil for 1 h at 20 V in a two-electrode configuration. The as-prepared porous film exhibite...

Abstract Stress shielding is known to cause bone refracture or low healing rate in fractured bones. The numerical study of process a transverse tibia was conducted this research reduce the stress shielding. and strain on callus were evaluated when plates different metallic non-metallic biomaterials used. Time varying material properties applied, loading conditions coupled with callus. distribut...

Polymers of intrinsic microporosity (PIMs) provide high surface area materials (typically 1000 m2 g?1 apparent BET area) that are processable from organic solvents to give glassy films or composite coatings. Multi-functionality for sensing with these is achieved (i) based on the polymer backbone itself being fluorescent chemically active (ii) guest species (chromophores, nano-catalysts, nano-ph...

liquefaction is one of the most important and complex topics in geotechnical earthquake engineering. in recent years, passive site stabilization method has been proposed for non-disruptive mitigation of liquefaction risk at developed sites susceptible to liquefaction using colloidal nano-silica stabilizer. in this research, 4 box models were used to investigate the ability to uniformly deliver ...

Abstract Nano-MgO was prepared by microwave irradiated ionic liquid method. The influence of the volume ([BMIM]Ac), radiation power and temperature on morphology nano-MgO were investigated. characterized TG, XRD, EDS SEM. results showed that this method has a short rod-like shape, uniform particle size, good dispersibility. average diameter rod-shaped 25 nm, length 67 specific surface area 48.2...

In this work, we demonstrate an innovative approach, combing a novel active screen plasma (ASP) technique with green chemical synthesis, for a direct fabrication of uniform Pt nanowire arrays on large-area supports. The ASP treatment enables in-situ N-doping and surface modification to the support surface, significantly promoting the uniform growth of tiny Pt nuclei which directs the growth of ...
