Sept. 15, 2021: In Memoriam: David Skinner

We are deeply saddened to announce the loss of David Skinner, our colleague from NERSC. The folks at NERSC have put together a very touching In Memoriam notice on David's passing. Among a lifetime of accomplishments, David was also instrumental in the early days of the Materials Project. David was known for his kindness, inspiration, and support of colleagues, and will be sorely missed.

June 3, 2021: Materials Project Virtual Workshop August 10th-12th

See the announcement here. Limited to 100 participants. We hope you can join us!

May 13, 2021: Database Release V2021.03.13 With New Formation Energy Correction Scheme

This release includes no new data but does change the way we correct formation energies. This reduces the overall error in formation energies in Materials Project by 7% when compared to experiment. The old correction scheme remains available for those who need to use it. More info in our release logs.

March 22, 2021: Supplemental Database Release V2021.03.22

This release updates some older materials with new calculations, and adjusts our rules for deprecating older calculations. It does not contain any new materials. Thanks to the new calculations many materials that were previously deprecated are now accessible again. This release is in preparation for a switch to our new compatibility scheme which will improve our predictions of formation energy.
