However, producing diamond particles with well-defined shapes at scale is challenging because diamonds are chemically inert and extremely hard. Here, we show air oxidation, a routine method for purifying diamonds, can be used to precisely shape diamond particles at scale. By exploiting the distinct reactivities of different crystal facets and defects inside the diamond, layer-by-layer outward-to-inward and inward-to-outward oxidation produced diverse diamond shapes including sphere, twisted surface, pyramidal islands","authors_text":"Dangyuan Lei, Fuqiang Sun, Jing Wang, Kwai Hei Li, Lei Shao, Ngai Wong, Qi Wang, Tongtong Zhang, Yaorong Wang, Ye Zhu, Yingchi Li, Yuan Lin, Zhiqin Chu, Zhongqiang Wang","cross_cats":["cond-mat.mes-hall"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2024-09-14T09:54:57Z","title":"Scalable Reshaping of Diamond Particles via Programmable Nanosculpting"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2409.09393","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":"sha256:4a831593238dc60cf3c9fc63fc0320d2e8bf06431dfeb3be73a8ca386377810d","target":"record","created_at":"2026-07-05T09:52:15Z","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":"314dd0bfb0fefb255e13f671eb0d0c6788760d15286066cd0e8b3e9684fbbcc5","cross_cats_sorted":["cond-mat.mes-hall"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2024-09-14T09:54:57Z","title_canon_sha256":"fa61ade2628d8da88e25dd3f7b9f5bfb080567ca0685690aa433e1363d7fa394"},"schema_version":"1.0","source":{"id":"2409.09393","kind":"arxiv","version":1}},"canonical_sha256":"0e3c20fa58c793a88edde6ecdf53be7e8a595f5288dcc384d2d0d5e8210bcc8f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0e3c20fa58c793a88edde6ecdf53be7e8a595f5288dcc384d2d0d5e8210bcc8f","first_computed_at":"2026-07-05T09:52:15.988884Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T09:52:15.988884Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"JK2+810gEwEGP1SffVibDriz4px3isJqqP+TRvlE7OJb1XlzUcn0zc3U0XNDO5EcJJOq1xJtSNeet+1JmYLrDQ==","signature_status":"signed_v1","signed_at":"2026-07-05T09:52:15.989448Z","signed_message":"canonical_sha256_bytes"},"source_id":"2409.09393","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4a831593238dc60cf3c9fc63fc0320d2e8bf06431dfeb3be73a8ca386377810d","sha256:31df0789fcf799aac3d5dca8cedd30d3020af386aa3f572304d94fd069d445d5"],"state_sha256":"bb768e2f0f942b5fe3052abc5d1897f8e14f1e7cbe62e5092529df3b63500043"}
