We report a new methodology to prepare activated carbon and activated carbons/ZnO composites from walnut shell-derived hydrothermal carbons (hydrochars), which were prepared under hydrothermal condition in presence of ZnCl 2 . For this method, activated carbon/ZnO composites were prepared via heat treatment of hydrochars under inert environment and activated carbons were prepared by removing...
A high mobility of 109.0 cm2 V−1 s−1 is obtained by thin‐film transistors (TFTs) comprising a composite made by aligning SnO2 nanowires (NWs) in amorphous InGaZnO (a‐IGZO) thin films. This composite TFT reaches an on‐current density of 61.4 μA μm−1 with a 10 μm channel length. Its performance surpasses that of single‐crystalline InGaZnO and is comparable with that of polycrystalline silicon.
Elastic wave propagation along the axis of a piezomagnetic cylinder imperfectly bonded by a piezoelectric layer is studied. The characteristic of the imperfect interface is expressed by the radial and the axial stiffness coefficients. The influences of the electro-magnetic boundary conditions, interface imperfection and geometry of the cylinder on the dispersion relations of elastic wave are discussed...
This paper, investigates the dispersion characteristics of shear horizontal (SH) surface waves propagating in a piezoelectric (PE) layer imperfectly bonded on a piezomagnetic (PM) half-space. Both the layer and half-space possess the hexagonal symmetry. The so-called shear-lag model is used to describe the interfacial property. The surface of the PE layer is traction-free, electrically closed and...
