Abstract Eleven fluorite oxides with five principal cations (in addition to a four-principal-cation (Hf0.25Zr0.25Ce0.25Y0.25)O2-δ as a start point and baseline) were fabricated via high-energy ball milling, spark plasma sintering, and annealing in air. Eight of the compositions, namely (Hf0.25Zr0.25Ce0.25Y0.25)O2-δ, (Hf0.25Zr0.25Ce0.25)(Y0.125Yb0.125)

High entropy oxides: The role of entropy, enthalpy and synergy
Scripta Materialia, 2020Abstract This viewpoint article focuses on some of the important issues related to the emerging field of high entropy oxides (HEOs). Open queries regarding the role of entropy, enthalpy, individual elements and synergy arising from the presence of multiple elements in HEOs are discussed.

Oxidation of CoCrFeMnNi High Entropy Alloys
JOM, 2015Eight model high entropy alloys (HEAs) in the CoCrFeMnNi family (including one alloy each in the CoCrFeNi and CoFeMnNi subfamilies) were made, prepared, and exposed to laboratory air for 1100 h at 650°C and 750°C. Two commercial alloys, nickel-base superalloy 230 (N06230) and austenitic stainless steel 304H (S30409), were simultaneously exposed for ...

General Synthesis of High-Entropy Oxide Nanofibers
ACS NanoThe discovery of high-entropy oxides (HEOs) in 2015 has provided a family of potential solid catalysts, due to their tunable components, abundant defects or lattice distorts, excellent thermal stability (ΔG↓ = ΔH - TΔS↑), and so on. When facing the heterogeneous catalysis by HEOs, the micrometer bulky morphology and low surface areas (e.g., 96%, CO2 ...

High Entropy Oxides: Structure and Properties
2020Since the origin of humankind numerous approaches have been employed to develop new materials. Of these approaches, changing the composition of a given system, typically referred as alloying for metallic and doping for non-metallic systems, is undoubtedly the most common way of designing new materials.
