Some materials (sulfides, seemingly) disappeared

The Materials Project website seems to be missing some materials which were formerly present in the database. For example, CaV2S4 is gone entirely. Previously it had an MP-ID of mvc-11260. There are many other missing sulfides which were previously in Materials Project. I can provide an explicit list if such is useful. Could someone please advise on whether we can expect these materials to return?


This is due to a sandbox issue and will be fixed soon. I will keep you posted once it is reappear.



Hi Dan,
