We conducted neutron total scattering measurements on lead-free Ba (Zr 0.2 Ti 0.8) O 3-0.5
(Ba 0.7 Ca 0.3) TiO 3 (BZT-0.5 BCT) ceramic at 300 K and 150 K, and studied both long-
range and local structures near the morphotropic phase boundary. Despite the long-range
phase transition from tetragonal to rhombohedral structures, we found that local atomic
structure of BZT-0.5 BCT barely changes between 300 K and 150 K. To incorporate both
long-range and local structures in a consistent way, we performed reverse Monte Carlo …

Recently, flexible nanogenerators have attracted much attention due to the continuous
demand of portable electronic devices. Thus, in our present work, a flexible piezoelectric
nanogenerator (pNG) was fabricated by mixing 0.5 Ba (Zr 0.2 Ti 0.8) O 3-0.5 (Ba 0.7 Ca 0.3)
TiO 3 nanoparticles (BCTZ NPs) and a PDMS polymer matrix. The flexible device exhibited
excellent performance with maximum open-circuit voltage of 0.6 V and short-circuit current of
7.5 nA. BCTZ NPs were prepared by a reaction between a metallic salt and a metallic oxide …
