The potential of NMR in 3D imaging tasks is by far greater, but there is only 'a handful' of MRI studies of particulate matter. The method is expensive, time-consuming, and requires a deep understanding of pulse sequences, signal acquisition and processing. We give a short introduction into the physical principles of this imaging technique, describe its advantages and limitations for the screening of granular matter and pre","authors_text":"Ralf Stannarius","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2017-03-03T15:38:35Z","title":"Magnetic Resonance Imaging of Granular Materials"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1703.01211","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:c8438337f0edae7450e8e4f7831e6d273b25db0c646bcc48197eee279fe6a622","target":"record","created_at":"2026-05-18T00:05:51Z","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":"7e273aa410434d33928b69498657b73743aafb2219a66bd9bfcdaafd26c85621","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2017-03-03T15:38:35Z","title_canon_sha256":"95b4b6a5a1283dd6a3580ba9418366e13fa1af146d7cfba02e62cbd891988cf9"},"schema_version":"1.0","source":{"id":"1703.01211","kind":"arxiv","version":1}},"canonical_sha256":"2d4d2ee2bafda5d90d00d397cc885fe149607911e9f925d3c829b18c81d00339","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2d4d2ee2bafda5d90d00d397cc885fe149607911e9f925d3c829b18c81d00339","first_computed_at":"2026-05-18T00:05:51.424116Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:05:51.424116Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Yvf4+HIEiEr/BgCL4PdJQkwTB8QUeICvu1H8/6Th0GMzsFJqv0aDg1zFRk6FDS1FUmmEw++CHUJuD8zexfpgDA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:05:51.424776Z","signed_message":"canonical_sha256_bytes"},"source_id":"1703.01211","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c8438337f0edae7450e8e4f7831e6d273b25db0c646bcc48197eee279fe6a622","sha256:1c575a4681ea743e00c313cccc114e39c60da6667fba1705d6c50bd6b6abfaa9"],"state_sha256":"0fe6192a12e59c397b3eb925eeab8218f56e7c04b217d603b2eacf240379180a"}
