Furthermore, a Hg-based cuprate with a critical temperature of 133 K was found. The 133 K is still the highest critical temperature of conventional superconductors under atmospheric pressure.\n  We have shown that materials obtained by bringing n-alkanes into contact with graphite are capable of conducting electricity with almost no energy loss at ","authors_text":"Yasushi Kawashima","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2016-12-15T22:31:58Z","title":"Superconductivity above 500 K in conductors made by bringing n-alkane into contact with graphite"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1612.05294","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":"sha256:00f063758fe8a12ae64ac556ab4afeb829856978495f497c815995441fa6cbf7","target":"record","created_at":"2026-05-18T00:54:52Z","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":"e7198c93852c8734ad41b74f306f561523e35eabb8c4dc09aaba0cccfc2ef6a4","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2016-12-15T22:31:58Z","title_canon_sha256":"f85d164ceeab4335fdc3c5f88541ebbf4d073b9a49fb0dc3bbf7536f59d9fa1a"},"schema_version":"1.0","source":{"id":"1612.05294","kind":"arxiv","version":1}},"canonical_sha256":"98aeb45591ba827756bccb83b64535cb63223aa6745842b1a3b2737514182521","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"98aeb45591ba827756bccb83b64535cb63223aa6745842b1a3b2737514182521","first_computed_at":"2026-05-18T00:54:52.115837Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:54:52.115837Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"vNPltRbYjUGQloeHhc465W46ef749xv410Thc3j+ayz1cRv21kRToaKItrCLIFo4C/qS52ldohRLOI3hB1WhDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:54:52.116313Z","signed_message":"canonical_sha256_bytes"},"source_id":"1612.05294","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:00f063758fe8a12ae64ac556ab4afeb829856978495f497c815995441fa6cbf7","sha256:e7d10c9cc53968f7d5bfcf23e87d4a78bf5354ee44acb3bd6e279d080636c367"],"state_sha256":"ca00ebfc85424a850611b5a8aeb4b714e566438d5a6221f717bad3c945428f1b"}
