However, the frequency factor increases with the generation of interfaces, which serve as sites for hydrogen diffusion and heterogeneous metal/hydride nucleation.","weakest_assumption":"That the increase in frequency factor and the shift in rate-controlling mechanism are caused specifically by the magnesium-graphene interphase boundaries rather than other processing-induced changes such as overall grain refinement or residual strain."}},"verdict_id":"1dc2fd1d-3f6a-4457-bc19-25427fe8b590"}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:648f7c96de09b854a02a5b58a0ee9f6a20f914cebc183d541c4cab598aee6de6","target":"record","created_at":"2026-05-18T03:08:56Z","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":"b082804415fd64d1d460dd4e929dc83ae576506b37dc65dad65b79b53f8f1415","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2026-05-13T08:42:41Z","title_canon_sha256":"34e193ae97df5612ace23cc5ecdd974faac1803db21180453c01907e29d6e07e"},"schema_version":"1.0","source":{"id":"2605.13184","kind":"arxiv","version":1}},"canonical_sha256":"9752e1647f611087e534c376a4a42314e359d0107e844fa5b9cd9670e468a8b5","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9752e1647f611087e534c376a4a42314e359d0107e844fa5b9cd9670e468a8b5","first_computed_at":"2026-05-18T03:08:56.300325Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:08:56.300325Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"O11JpV03bMIlQwagjFkohI6a6Tn7qBJqKvsqjlV2kWhJN+q3QpRyJPJLh6wZf6QH5QBedEibDK+Zq9GVLp7mDA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:08:56.300886Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.13184","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:648f7c96de09b854a02a5b58a0ee9f6a20f914cebc183d541c4cab598aee6de6","sha256:92afa2ee4193a0c7c44005238eb12c80744f330e4f8ef24f63dc14cd42b530b5"],"state_sha256":"d67bee3b93405734482f430b5d9cad0e05a05c5b5d996ea0388acf6a438abdae"},"bundle_signature":{"signature_status":"signed_v1","algorithm":"ed25519","key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signature_b64":"rQYDengJbtVr75o3GTSZkZ+7KIBubuHacytMNoBEWYu8+HtekXoiZv/B7x+WoFkFDElQ36nbHLhRXAWJzvKNBA==","signed_message":"bundle_sha256_bytes","signed_at":"2026-05-24T12:20:29.755233Z","bundle_sha256":"9e6f39bbefe367f6f64c468fa30cf87a73aa9515c7fa54f3bfc55a6ed9145fef"}}
