In recent years, the concept of entropy stabilization of crystal structures in oxide systems has led to an increased research activity in the field of “high entropy oxides”. These compounds comprise the incorporation of multiple metal cations into single-phase crystal structures and interactions amon...
Here, we review recent progress in understanding the salient features of high-entropy alloys. Model alloys whose behaviour has been carefully investigated are highlighted and their fundamental properties and underlying elementary mechanisms discussed. We also address the vast compositional space that remains...
具有元素复杂性和成分多样性的单相氧化物(single-phase oxides),通常被称为高熵氧化物(high entropy oxides),其特征是多金属元素以等原子浓度均匀分散。高熵氧化物的不寻常特性赋予了它们在清洁能源相关电催化中的潜在应用,但是构型熵与催化机理之间可能存在的基本关系仍未得到很好的理解和确立。基于此,厦门大学孙毅飞副...
(4), the Goldschmidt tolerance factor is an appropriate tool which can be used to examine the formation of single-phase perovskite oxides. Jiang et al. [139], who fabricated perovskites with a high configurational entropy (≥ 1.5R), used the tolerance factor as a descriptor for the design ...
(near) equimolar mixtures and achieve more robust systems, which became known as high-entropy materials. Initial research focused mainly on metal alloys and nitride films. In 2015, entropy stabilization was demonstrated in a mixture of oxides. Other high-entropy disordered ceramics rapidly followed, ...
Herein, we provide a comprehensive review of this new class of materials in the energy field. We begin with discussions on the latest reports on the applications of high-entropy materials, including alloys, oxides and other entropy-stabilized compounds and composites, in various energy storage and...
