The history and current status of materials data activities from handbook to database are reviewed, with introduction to some important products. Through an example of prediction of interfacial thermal resistance based on data and data science methods, we show the advantages and potential of material informatics to study material issues which are too complicated or time consuming for conventional theoretical and experimental methods. Materials big data is the fundamental of material informatics. The challenges and strategy to construct materials big data are discussed, and some solutions are proposed as the results of our experiences to construct National Institute for Materials Science(NIMS) materials databases. 展开更多

Discovering new materials with excellent performance is a hot issue in the materials genome initiative.Traditional experiments and calculations often waste large amounts of time and money and are also limited by various conditions. Therefore, it is imperative to develop a new method to accelerate the discovery and design of new materials. In recent years, material discovery and design methods using machine learning have attracted much attention from material experts and have made some progress. This review first outlines available materials database and material data analytics tools and then elaborates on the machine learning algorithms used in materials science. Next, the field of application of machine learning in materials science is summarized, focusing on the aspects of structure determination, performance prediction, fingerprint prediction, and new material discovery. Finally, the review points out the problems of data and machine learning in materials science and points to future research. Using machine learning algorithms, the authors hope to achieve amazing results in material discovery and design. 展开更多

The introduction of density functional theory(DFT)and electronic structure has brought computational methods into the field of materials science.In these theoretical calculations,quantum mechanics is predominantly used.Machine learning(ML)and high-throughput computing share some inherent similarities,as both can extract valuable information from massive datasets and possess parallelism and scalability.ML techniques simulate human thought processes,with algorithms that make decisions and have good scalability and strong generalization abilities.The combination of high-throughput and ML technologies leverages the advantages of high-throughput technology standardization and high capacity,addressing the challenges faced by ML at the front end.This complementary combination is expected to further enhance the efficiency of material screening and development.In data mining,using ML methods on various databases,the interrelationships between molecular structures and properties are discovered from large amounts of data.Mapping,current utilization of DFT,materials genomics,and high-throughput computing have generated a substantial amount of data.This review provides new insights into the development of electrochemistry. 展开更多
