Showcasing the Structure and Properties of Lanthanide‐Doped BaTiO3
Understanding the defect chemistry of Ln‐doped BTO, as well as the distribution of Ln ions inside the BTO host, is a challenge in the study of functional perovskite oxides. It provides important insights into the future development of Ln‐doped BTO materials, particularly in the context of low‐carbon transition strategies and renewable technologies that

Large electrocaloric effect in Ba(Ti1−xSnx)O3 ceramics over a broad temperature region
A large electrocaloric effect (ECE) near room temperature is reported in Sn doped BaTiO3 ceramics. By tuning Ba(Ti1−xSnx)O3 compositions which also exhibit relaxor ferroelectric response to near the invariant critical point, the Ba(Ti1−xSnx)O3 bulk ...

Colossal Barocaloric Effects at Triple‐Phase Points
Colossal barocaloric effects were achieved in odd‐numbered normal alkane systems, such as C17H36, C19H40 and C21H44 approaching triple‐phase point by overlapping two separated phase transitions of ordered‐disordered solid phase transition and solid–liquid phase transition under a relative low pressure.

Positive and negative electrocaloric effect in BaTiO$_3$ in the presence of defect dipoles
The influence of defect dipoles on the electrocaloric effect (ECE) in acceptor doped BaTiO$_3$ is studied by means of lattice-based Monte-Carlo simulations. A Ginzburg-Landau type effective Hamiltonian is used.

Efficient Cooling System Using Electrocaloric Effect
The electrocaloric effect in thin films of an electrocaloric material has the potential to be used for efficient cooling systems for high power electronic devices. We numerically calculated the effect of parameters in electrocaloric refrigeration with a thermal switch of fluid motion on the thermal performance. The system of changing air and water
