A reliable, general approach to evaluate absorption coefficient spectra from the optical measurements of the nanoparticle-pigmented coatings is developed based on solving the inverse problem using four-flux-radiative method. The derived absorption properties of NP materials can be directly applied to predict the solar absorptance, optimize the nanoparticle-pigmented coatings, and analyze the thermal degradation, which agree well with the experimental results.","authors_text":"Can Xu, Jifeng Liu, Xiaoxin Wang","cross_cats":["cond-mat.mtrl-sci"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2023-01-03T16:50:51Z","title":"Extracting optical parameters of Cu-Mn-Fe spinel oxide nanoparticles for optimizing air-stable, high-efficiency solar selective coatings"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2301.01194","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":"sha256:17fb56be67bb4abfe12fc15136af41b30137892d94851c0c99073a2e50dbe859","target":"record","created_at":"2026-07-05T05:30:21Z","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":"9c026a1ae468fdb1716940cbd2f143f2e728dabf90b699506070704dee259718","cross_cats_sorted":["cond-mat.mtrl-sci"],"license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2023-01-03T16:50:51Z","title_canon_sha256":"b07c52686d0e4d63f19c256289bdfd56010128475910d539e6d1babb3bb44c5c"},"schema_version":"1.0","source":{"id":"2301.01194","kind":"arxiv","version":1}},"canonical_sha256":"be9e3d36aa7cd9c0a3a1b669a2d6d7e0d23d9267ba6d2a7e388e70690b74097f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"be9e3d36aa7cd9c0a3a1b669a2d6d7e0d23d9267ba6d2a7e388e70690b74097f","first_computed_at":"2026-07-05T05:30:21.447732Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:30:21.447732Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"5ZSq4DQ9mwRn7SsKPh01tss11r+WEL/fvY8KuPBlpcFF9aZwk5ppOKZ8BjtVeN1euXgpmF1YRQTgHLzScZijBg==","signature_status":"signed_v1","signed_at":"2026-07-05T05:30:21.448077Z","signed_message":"canonical_sha256_bytes"},"source_id":"2301.01194","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:17fb56be67bb4abfe12fc15136af41b30137892d94851c0c99073a2e50dbe859","sha256:2eff0a378233301bbf13186fe519e3bf0716e92bec039c67c49003d6daff94cf"],"state_sha256":"dc6aaea13bfa7b36acc98e46dd2481a25ee141f29844add67ce8321fdbfb41f0"}
