More precisely, this procedure combines density functional theory and harmonic phonon calculations with tabulated thermochemical data to predict the heat capacity, formation energy, and entropy of important metal oxides. Alloy cluster expansions are, moreover, employed to represent phases that display chemical ordering as well as to calculate the configurational contribution to the specific heat capacity. The methodology can, therefore, ","authors_text":"Anders Hellman, Ivana Stani\\v{c}i\\'c, Joakim Brorsson, Jonatan Gastaldi, Tobias Mattison","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2023-05-11T14:20:48Z","title":"Thermodynamic properties for metal oxides from first-principles"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2305.06828","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:5744d71c0a7bf493068dac58a693bcfe367470d59e92bcda26e249b6e3f502a1","target":"record","created_at":"2026-07-05T06:09:16Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"9dba26d368bf203cc1b86bc9c04cad1272fd337d1f306e7463dec2bc5f84b7e0","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2023-05-11T14:20:48Z","title_canon_sha256":"6f2c512f9c338f169cb2817b65d597f0af2cf7f6a932f777efbd12f057622680"},"schema_version":"1.0","source":{"id":"2305.06828","kind":"arxiv","version":1}},"canonical_sha256":"8728cfc3767ccd2db23bc69af47b2ca95c9d6cf65462f15c8b9b953dcd0a213c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8728cfc3767ccd2db23bc69af47b2ca95c9d6cf65462f15c8b9b953dcd0a213c","first_computed_at":"2026-07-05T06:09:16.762115Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T06:09:16.762115Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"uFG/XjLnHtqoBT55PTJCTDJTk9ukc5PHmYGb7Y33blbSLDN54yH5CPELjcNFMpJGyz7kS1o5GMxXJozyNiTfAQ==","signature_status":"signed_v1","signed_at":"2026-07-05T06:09:16.762539Z","signed_message":"canonical_sha256_bytes"},"source_id":"2305.06828","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5744d71c0a7bf493068dac58a693bcfe367470d59e92bcda26e249b6e3f502a1","sha256:b447402451f41162a4f7b5c9a2e6f791bdba6a53f1e4c407ee8c2bffb5851f39"],"state_sha256":"fd0109c8cd6caa882b75b336c82702c123106c8065d543992fdaee003a944322"}
