  摘要：Materials with a high electrocaloric effect (ECE)1,2 tend to favour a disordered yet easily tunable polar structure. Perovskite ferroelectrics3 stand out as ideal candidates owing to their high dielectric responses and reasonable thermal conductivity. The introduction of multielement atomic distortions induces a high-polar-entropy state4 that notably increases the ECE by effectively overcoming the constraints imposed by highly ordered, polar-correlated perovskite structures. Here we developed ...

  摘要：Structural disorder within materials gives rise to fascinating phenomena, attributed to the intricate interplay of their thermodynamic and electrochemical properties1,2. Oxygen-redox (OR) electrochemistry offers a breakthrough in capacity limits, while inducing structural disorder with reduced electrochemical reversibility3, 4-5. The conventional explanation for the thermal expansion of solids relies on the Gr & uuml;neisen relationship, linking the expansion coefficient to the anharmonicity o...

  摘要：Ceria nanoparticles supported on alumina are widely used in various catalytic reactions, particularly in conjunction with platinum group metals (PGMs)1, 2, 3, 4, 5, 6, 7, 8-9. Here we found that treating these catalysts at temperatures between 750 and about 1,000 degrees C in the presence of CO and NO in steam (reactive treatment under reducing atmosphere) leads to the dispersion of ceria nanoparticles into high-density 2D (roughly one atomic layer thin) CexOy domains, as confirmed by microsco...
