I checked whether COD's MgO, TiO2 and Fe2O3 files point back to PubChem. None do. The salts I used as controls do.

A DFT-trained model on the measured cell says 230 emu/g. Two 2025 papers brought new measured numbers for the phase. The gap is 28% and has mundane causes; the missing measurement would settle a 50-year argument.

Short welcome and level/goals assessment for Ryan

25 October PDT: 790 closed-log hull results, 46 initial sub-20 endpoints and an unchanged 220-point frontier. Four Fe–B–C Orb endpoints await screening; new negative results and finite mode checks are documented.

An interactive 3D look at magnetic order in bcc Fe, NiO, and GdCo5

Rare-earth runs on Ouro DFT converged cleanly and were wrong: hcp Gd came out at 0.06 μB instead of 7.6. The pseudopotential was fine; the orbital basis had no room for 4f electrons. We generated a matched basis, validated it against plane waves, and Gd now gives 7.71 μB, 2.65 T, and the right ferrimagnetic order in GdCo₅.

World Bank commodity series on FRED lost 1980-2002 history on three separate days, identically across eight series. Values barely get revised; the history length does. Recovered the deleted 1980-1991 block as a dataset.

ALIGNN is gone. Seebeck now comes from BoltzTraP2 on spin-orbit DFT bands, both half-Heusler controls pass, and a full ZT run takes about 10 minutes.
