Monodispersed bimetallic PdAg nanoparticles can be fabricated through the emulsion-assisted ethylene glycol (EG) ternary system. Different compositions of bimetallic PdAg nanoparticles, Pd₈₀Ag₂₀, Pd₆₅Ag₃₅ and Pd₄₆Ag₅₄ can be obtained via adjusting the reaction parameters. For the formation process of the bimetallic PdAg nanoparticles, there have two-stage… (More)
Monodisperse bimetallic Pd-Cu nanoparticles with controllable size and composition were synthesized by a one-step multiphase ethylene glycol (EG) method. Adjusting the stoichiometric ratio of the Pd and Cu precursors afforded nanoparticles with different compositions, such as Pd(85)-Cu(15), Pd(56)-Cu(44), and Pd(39)-Cu(61). The nanoparticles were separated… (More)
First-principles calculations are employed to study the surface relaxation and electronic structure of the fully relaxed SrTiO(3) (001) oxygen-vacancy surfaces with both Sr and Ti terminations. In contrast to the perfect surface, the larger surface rumples and smaller interlayer distances have been found. Some in-gap Ti 3d states at about -1.13 eV below the… (More)
An easy-to-scale-up multiphase emulsion-assisted synthetic strategy based on a ternary metal precursor/surfactant/ethylene glycol system has been established to prepare monodispersed bimetallic nanoparticles with designated size and composition; the nanoparticles thus prepared are easily separable from the reaction mixture.
A facile one-pot approach is successfully developed to construct the stable Au nanochains with silica shell via self-assembly and classical Stöber process. The resulting Au chain@SiO2 nanoparticles holds great promise for serving as a safe, reusable, and high-performance photothermal agent against cancer.
Au-BiVO(4) heterogeneous nanostructures have been successfully prepared through in situ growth of gold nanoparticles on BiVO(4) microtubes and nanosheets via a cysteine-linking strategy. The experimental results reveal that these Au-BiVO(4) heterogeneous nanostructures exhibit much higher visible-light photocatalytic activities than the individual BiVO(4)… (More)
Surface-enhanced Raman scattering (SERS) probes are made by facile photochemical deposition of silver nanoparticles on a femtosecond (fs) laser ablated, D-shaped fiber. The structure and surface morphology of the probe are investigated by scanning electron microscopy. High-quality SERS signals are detected using Rhodamine 6G molecules via an in situ sensing… (More)
OBJECTIVE To assess postoperative effects of microelectrode-guided posteroventral pallidotomy (PVP) for Parkinson's disease. METHODS Intraoperative microelectrode recordings and microstimulation were used to explore the globus pallidus to performance of posteroventral pallidotomy in 48 patients with Parkinson's disease (47 unilateral and 1 bilateral).… (More)
Novel V-groove all-fiber core-cladding intermodal interferometers fabricated by CO2 laser irradiation on a standard single-mode fiber are described. The high-order cladding modes are excited due to the special V-groove structure. The interferometers are classified as Mach-Zehnder and Michelson type based on the way they are structured. Benefiting from the… (More)
This paper demonstrates an improved laser-induced deposition of silver nanoparticles method based on fiber surface micro-grating for surface-enhanced Raman scattering (SERS). The femtosecond (fs) laser ablation is used to create a roughened surface with micro-grating structures on the cleaved fiber end, which is beneficial for silver nanoparticles growth,… (More)
