One-step synthesis of silver saw-like nanosheets was introduced by using aqueous AgNO3 and benzene-soluble p-phenylenediamine (pPD). Based on the X-ray diffraction pattern and selected-area electron diffraction pattern, the
silver was single crystal. As indicated by Scanning Electron Microscopy, Transmission Electron Microscopy and the auxiliary characterization by Fourier transform infrared and Raman Spectroscopy, the nanosheets are ~ 20 μm in edge length and are coated by poly(p-phenylenediamine) (PpPD) thin films. The role of oil/water interface and PpPD on the formation of sheet-like morphology was analyzed. This method is facile and cost-effective.
A new shifted Chebyshev operational matrix (SCOM) of fractional integration of arbitrary order is introduced and applied together with spectral tau method for solving linear fractional differential equations (FDEs). The fractional integration is described in the Riemann–Liouville sense. The numerical approach is based on the shifted Chebyshev tau method. The main characteristic behind the Hollister Canada Coupon Code
approach using this technique is that only a small number of shifted Chebyshev polynomials is needed to Magasin Hollister Montreal
obtain a satisfactory result. Illustrative examples reveal that the present method is very effective and convenient for linear multi-term FDEs.
