A high entropy oxide as high-activity electrocatalyst for water oxidation [PDF]

, 2022
High entropy materials are a new pathway in the development of high-activity (electro )catalysts because of the inherent tunability and coexistence of multiple potential active sites, which may lead to earth-abundant catalyst materials for energy-efficient electrochemical energy storage.

Designing Magnetism in High Entropy Oxides [PDF]

Advanced Science, 2022
AbstractIn magnetic systems, spin and exchange disorder can provide access to quantum criticality, frustration, and spin dynamics, but broad tunability of these responses and a deeper understanding of strong limit disorder are lacking. Here, it is demonstrated that high entropy oxides present a previously unexplored route to designing materials in ...

High-entropy oxides in the mullite-type structure [PDF]

Chemistry of Materials, 2022
High-entropy materials (HEM) represent a new class of solid solutions containing at least five different elements. Their compositional diversity makes them promising as platforms for development of functional materials. We synthesized HEMs in a complex mullite-type structure challenging previous assumptions that HEMs only form in simple structures.

Understanding the Role of Entropy in High Entropy Oxides

Journal of the American Chemical Society, 2023
The field of high entropy oxides (HEOs) flips traditional materials science paradigms on their head by seeking to understand what properties arise in the presence of profound configurational disorder. This disorder, which originates from multiple elements sharing a single lattice site, can take on a kaleidoscopic character due to the vast numbers of ...

Thermodynamics of high entropy oxides [PDF]

Acta Materialia, 2021
Abstract With the hype of “high entropy” alloys and more recently, “high entropy” ceramics and “high entropy” oxides (HEOs), there has been a great push to investigate and characterize systems with 5 or more components. This push has been extremely beneficial for the materials community as it has led to the development of many new systems with ...
