High-entropy materials, including alloys and oxides, have gained significant attention in recent years due to their unique properties and potential applications. These materials are composed of multiple principal elements, which leads to enhanced entropy and improved performance. Researchers have explored various synthesis methods, including flame aerosol synthesis, carbothermal shock reduction, and liquid metal synthesis, to produce high-entropy nanoparticles and ceramics.
Studies have demonstrated the potential of high-entropy materials in various fields, such as catalysis, energy storage, and conversion. For example, high-entropy alloy nanoparticles have shown improved catalytic activity and stability, while high-entropy oxides have exhibited enhanced ionic conductivity and electrochemical performance.
Theoretical models, such as molecular dynamics simulations, have been used to understand the behavior of high-entropy materials and predict their properties. Researchers have also investigated the effects of surface strain, defect density, and elemental distribution on the performance of high-entropy materials. These studies have provided valuable insights into the design and optimization of high-entropy materials for various applications, and have paved the way for further research and development in this field.
