An ultrahigh piezoelectric coefficient is always desired for electromechanical devices and systems. However, a long time, large d33 value in lead-based lead-free ceramics was usually obtained at the expense of their Tc, vice versa, limiting practical applications. Here, we proposed design concept, i.e., integrating phase boundary defect engineering, to resolve above challenges, based on concrete example Fe-modified 0.51Pb(Hf0.35Ti0.65)O3–0.49Pb(Nb2/3Ni1/3)O3 (0.51PHT–0.49PNN) ceramics....
Amorphous and monoclinic wolframite NiWO4 nanoparticles are successfully synthesized by annealing the NiWO4_70 sample obtained via simple chemical precipitation approach at 300 600 °C, respectively. With elevated temperature, specific surface area reduces appreciably with decreasing porosity. The electrical conductivity of amorphous NiWO4_300 enhances almost 1 order magnitude than that crystal NiWO4_600 sample. electrochemical properties NiWO4_x (x = 600) as electrodes supercapacitors...
