NiS2 hollow spheres are successfully prepared by a one-step template free method. Meanwhile, α-NiS hollow spheres can also be synthesized via the calcination of the pre-obtained NiS2 hollow spheres at 400 °C for 1 h in air. The electrochemical performances of the as-prepared NiS2 and α-NiS hollow sphere products are evaluated. When used for supercapacitors, compared with NiS2 hollow spheres, th...

The hydrothermal method was used to synthesize carbon sphere, and the hard template synthesis prepared C-doped hollow TiO2 sphere (CHTS). Bismuth nitrate as bismuth source modify CHTS. composite material oxidized in air atmosphere at 450℃ obtain Bi2O3 modified spheres(BCHTS). morphology, elemental composition photocatalytic degradation efficiency of tetracyclines (TC) by BCHTS spheres were char...

The preparation of hybrid hollow capsules consisting of a cross-linked polymer shell and a coating of graphene oxide (GO) is demonstrated. The capsules are prepared by Pickering miniemulsion polymerization, exploiting the surface activity of GO for its use as a colloidal surfactant. This approach represents a simple and convenient route towards hollow carbon nanostructures for a variety of appl...

Epimorphin was recently described as a mesenchymal factor modulating morphogenesis of murine mammary ducts, skin, liver, and lung in vitro. In this study epimorphin was analyzed in a human, pancreatic adenocarcinoma cell line (A818-6) which develops single layer epithelial hollow spheres resembling normal pancreatic ductal structures in vitro. Soluble 34- and 31-kD isoforms of epimorphin were f...

ZnO-SnO2 hollow spheres were successfully synthesized through a hydrothermal method-combined carbon sphere template. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Fourier transform infrared spectroscopy (FT-IR). The average diameter of hollow spheres is about 150 nm. The photocatalytic activity of the a...

Thermo-elastic analysis of a functionally graded hollow sphere is carried out and numerical solutions of displacement, stress and thermal fields are obtained using the Polynomial differential quadrature (PDQ) method. Material properties are assumed to be graded in the radial direction according to a power law function, ho...
