What is the Materials Project database designed for?
The Materials Project provides open web access to accurate information about known and suspected materials, as well as private access to the information needed to quickly and experimentally obtain these materials.
The Materials Project stores the results of material property calculations in the form of multi-level dictionaries and provides an API for loading and editing them. This data eliminates the need for experimental elastic property measurements when obtain new materials.
The Materials Project provides open web access to information about all known materials, as well as tools for downloading the data to local storage.
The Materials Project provides open web access to information about known and suspected materials, as well as analysis tools for theoretical and experimental development of materials.
