Although recently substantial progress has been reported on confined carbyne synthesized inside double-walled carbon nanotubes (DWCNTs), its formation mechanism and precursors for growth remain elusive. Here, we show a rational design of isotope engineered ultra-clean DWCNTs as tailored hosts to trace the growth of carbyne, which allows to identify the precursor and unravel the formation mechanism of carbyn","authors_text":"Ferenc Simon, Lei Shi, Paola Ayala, Thomas Pichler, Weili Cui, Yifan Zhang","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2022-11-09T12:46:04Z","title":"Ultra-clean isotope engineered double-walled carbon nanotubes as tailored hosts to trace the growth of carbyne"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2211.04852","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":"sha256:10f631198847309da1ce7fdce28610e72268556a7acb7663d63e6886744b825a","target":"record","created_at":"2026-07-05T05:14:42Z","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":"04bfef110619a4c7863c0a12a16f96ed41bbc87ea485dd56318510194ace582d","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2022-11-09T12:46:04Z","title_canon_sha256":"e29ca217bdd8b7f04286bd6281fd3bbd31c0589e5d9101835309b0d88181d5f8"},"schema_version":"1.0","source":{"id":"2211.04852","kind":"arxiv","version":1}},"canonical_sha256":"ddec25ca2277c98987fcfae049bc149b485145d2a220dcbaf691f3155bf70372","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ddec25ca2277c98987fcfae049bc149b485145d2a220dcbaf691f3155bf70372","first_computed_at":"2026-07-05T05:14:42.569427Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:14:42.569427Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"TdHKAt1QM7atxJVnxz2V8qtDLQKoTyyr1phY94KXYG+Po6YUFPMLI5bmttHVX6Qxs7gGTGiiPtx4pgKo1G+bAQ==","signature_status":"signed_v1","signed_at":"2026-07-05T05:14:42.569835Z","signed_message":"canonical_sha256_bytes"},"source_id":"2211.04852","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:10f631198847309da1ce7fdce28610e72268556a7acb7663d63e6886744b825a","sha256:0743fc0a5100f9450f726741fd116dc0939056be6202a3a2825781fd6423b82c"],"state_sha256":"04e17005eb2a7f8c525b436206aa29d7f42c0f6240867c5a50960239b3abb0d8"}
