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.
