Electrical energy storage systems (EESSs) with high energy density and power density are
essential for the effective miniaturization of future electronic devices. Among different EESSs …

The increasing energy consumption and environmental degradation have led governments
to pay attention to conversion, storage and management of renewable and clean energy …

Defects, in particular vacancies, play a crucial role in substituted perovskite systems,
influencing the structural features that underpin ferroelectricity. B-site vacancies introduce …

Core–shell nanofillers designed for dielectric nanocomposites are expected to integrate
high relative permittivity (ε r) and breakdown strength (E b). However, conventional core …

Abstract A series of (1-x) K 0.5 Na 0.5 NbO 3-xBa (Zn 1/3 Nb 2/3) O 3 ((1-x) KNN-x BZN)
nanostructural ceramics was successfully synthesised via solid-state reactions. These …

The functional properties of a series of BaTiO 3 ceramics, having grain sizes ranging from 75
nm to 2.25 μm, with polymorph coexistence around room temperature are presented. Large …

It is well known that disordered relaxor ferroelectrics exhibit local polar correlations. The
origin of localized fields that disrupt long‐range polar order for different substitution types …

Piezoelectric catalysis, which converts mechanical energy into chemical activity, has
important applications in environmental remediation. However, the piezo-catalytic activity of …

We report herein the variations in the Raman and Fourier-transform infrared (FTIR) spectra
of barium titanate (BT) induced by individual doping of yttrium at the Ba sites and of tin at the …

Despite being applied with success in many fields of materials science, Raman
spectroscopy is not yet determinant in the study of electroceramics. Recent experimental …
