High‐Quality Epitaxial Five‐Layer Aurivillius Films with In‐Plane Ferroelectricity for Electrocaloric Cooling

Advanced Electronic Materials, EarlyView.
High‐quality epitaxial five‐layer Sr2Bi4Ti5O18Aurivillius films are grown on SrTiO3 by pulsed laser deposition. The electrocaloric effect derived from measurements of the in‐plane ferroelectric polarization reveals a maximum temperature change of ΔT ∼ 0.95 °C under an electric field of 150 kV cm⁻¹ at 135 °C.

Piezo‐Electro‐Catalytic Hydrogen Production via Piezoelectric Fluoropolymers

Advanced Energy and Sustainability Research, EarlyView.
Piezo‐electro‐catalysis is demonstrated to double the efficiency of hydrogen production from acid by combining a self‐poled fluoropolymer with a platinum mesh. The improvement is attributed to localization of H3O+ ions at the catalytic interface, along with dielectric‐conductor electrochemical improvements. This technology is simple to integrate into a
