Enthalpy-change driven synthesis of high-entropy perovskite nanoparticles

Influence of composition on structural evolution of high‐entropy zirconates—cationic radius ratio and atomic size difference

“…Therefore, HEOs are currently examined in a variety of research fields like (electro) catalysis, energy storage, electrode materials, and thermal barrier coatings (TBCs). [9][10][11][12][13][14][15][16][17][18] For TBCs, stability at high temperatures is one prerequisite for the materials used. Due to their high melting points, high-temperature phase stabilities, and low thermal conductivities, pyrochlore-type rare-earth zirconates with a general formula of A 2 Zr 2 O 7 have been extensively studied as a future TBC material.…”

Thermally controlled growth of photoactive FAPbI3 films for highly stable perovskite solar cells

“…During heating and cooling at specific temperatures, a phase transformation occurs, accompanied by enthalpic and entropic thermodynamic changes. [49][50][51] Phase transitions can emerge via different kinetics pathways, for example, when applying rapid thermal annealing and quenching processes at different rates. [52][53][54][55][56][57][58] Accordingly, we applied 17 pulse times and respective intensities to the spin-coated FAPbI 3 wet films using our IR photonic annealing method.…”

High‐Entropy Catalyst—A Novel Platform for Electrochemical Water Splitting

“…Ball milling is a facile and effective method that utilizes mechanical force to promote five or more elements to form HEA powder. [ 130 ] The mixture of HEA powder precursors with certain proportions was conducted in a planetary high‐velocity ball mill together with the milling media. [ 131 ] The mechanochemical force can generate more grain boundaries and interfaces and is expected to continuously grind precursor particles to the nanoscale.…”
