About this project
This database is focusing on the high entropy materials, which are a new class of materials that have received significant attention in materials science and engineering over the last decade. The high-entropy concept addresses the importance of entropy engineering through incorporating of four or more elements with near equal molar ratio into a uniform single-phase structure. The high entropy materials conventionally possess four core effects: (1) high mixing entropy; (2) severe lattice distortion; (3) sluggish diffusion, and (4) cocktail effect, rendering unique and promising structure and properties that can be applied for various applications.
A unique feature of this project is studying of nanoscale high entropy materials. First, nanoscale size, surface, and functionality could enable critical applications in catalysis, plasmonic, and biomedical applications. In addition, the small size of these nanoscale high entropy materials could critically facilitate the high-throughput synthesis and precise theoretical calculations, which in bulk materials are very challenging. In the database, we will include models of theoretical calculation for high entropy materials, experimental data from rapid synthesis and screening, and also machine learning for existing data.
