Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adfm201470060-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>On page 1300, by modifying BaTiO₃ ceramics to their invariant critical points, Ba(ZrxTi_1−x)O₃ bulk ceramics exhibit a large electrocaloric effect (ECE). Q. M. Zhang and co‐workers show tetragonal, orthorhombic, and rhombohedral structures behind a larger cubic structure, with dipoles inside. A flat‐panel cooling device is schematically drawn as a 3D multi‐layered ECE cooling device. The temperature gradient is shown by rainbow color, in which blue indicates the cold end and the other warmer colors indicate higher temperatures. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4sr7pxvr" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
