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.
Check it out now. It is fixed.
