The lead-free sodium bismuth titanate (BNT) system has been extensively investigated in
the past decade due to its multi-functional electro-active properties. Here, we present a …

The elimination of lead in piezoelectric applications remains challenging. Since the
advances in the piezoelectricity were found in the perovskite family in 2000, studies into lead …

Here, we introduce phase change mechanisms in lead-free piezoceramics as a strategy to
utilize attendant volume change for harvesting large electrostrain. In the newly developed …

Thermodynamics is a science concerning the state of a system, whether it is stable,
metastable or unstable, when interacting with the surroundings. In this overview …

Strain engineering in perovskite oxides provides for dramatic control over material structure,
phase, and properties, but is restricted by the discrete strain states produced by available …

Electric field-induced transformations occur in a myriad of systems with a variegated
phenomenology and have attracted widespread scientific interest due to their importance in …

Due to growing concern for the environment and human health, searching for high-
performance lead-free piezoceramics has been a hot topic of scientific and industrial …

Increasing concern has been focused on the search for ecofriendly dielectric ceramics to
meet the extensive demands of pulsed capacitors. Due to the advantages of high-energy …

The electrocaloric effect (ECE) is significantly critical for environmentally friendly cooling
technologies to replace vapor compression-based refrigeration. Lead-free bismuth sodium …

As an emerging solid‐state refrigeration technology with zero‐emission and high energy
