Materials Experiment and Analysis Database

The Materials Experiment and Analysis Database (MEAD) is a public repository that contains raw data and metadata generated from millions of materials synthesis and characterization experiments performed by scientists at Caltech's Joint Center for Artificial Photosynthesis (JCAP) High Throughput Experimentation (HTE) Project. This repository also contains the analysis and distillation of that data into property and performance metrics computed via customized software published in an accompanying open source repository. This unprecedented quantity and diversity of experimental data is searchable by experiment and analysis attributes generated by both researchers and data processing software. Through a web-based interface, users can download experiment and analysis files in the form of zipped packages containing data with full annotations of their lineage. As the world’s largest open source materials database, MEAD provides substantial challenges and opportunities for incorporating data science in the physical sciences. Its associated data and algorithm management framework foster increased incorporation of automation and autonomous discovery in materials and chemistry research.

材料实验与分析数据库（Materials Experiment and Analysis Database，MEAD）是一个公开存储库，收纳了加州理工学院（Caltech）人工光合作用联合中心（Joint Center for Artificial Photosynthesis，JCAP）高通量实验（High Throughput Experimentation，HTE）项目组的科研人员开展的数百万次材料合成与表征实验所产生的原始数据与元数据。该存储库同时收录了经分析提纯后的实验数据，即通过配套开源存储库中发布的定制化软件计算得到的材料属性与性能指标。这类规模与多样性均前所未有的实验数据，可通过科研人员与数据处理软件生成的实验及分析属性字段进行检索。用户可通过网页端交互界面，下载打包为压缩文件的实验与分析文件，压缩包内包含带有完整溯源谱系标注的原始数据。作为全球规模最大的开源材料数据库，MEAD为物理科学领域融入数据科学技术提供了显著的挑战与发展机遇。其配套的数据与算法管理框架，能够推动自动化与自主发现技术在材料与化学研究中的进一步应用。
