# Chemistry reference-library gaps

**Audit date:** 2026-08-15

This is a retrieval checklist, not evidence. Missing papers must not be
recreated or represented as locally available.

| Reference used by active material | Expected local record | Status / gate |
|---|---|---|
| H. Zhang et al., *Journal of Energy Storage* (2026), article 123777; sodium-sulfate SAT study | Local PDF or author manuscript | Missing; retrieve and archive before relying on the 2026 result beyond the cited DOI |
| Z. Zhang et al., *Journal of Energy Storage* 34 (2021), 102186; NaCl/CMC SAT study | Local PDF or author manuscript | Missing; retrieve and archive before expanding the NaCl/CMC branch |
| A. Safari et al., *CrystEngComm* 23 (2021), DOI `10.1039/D0CE01454K`; SAT phase behaviour cited by SAT-HM-001 | Local PDF or stable author copy | Missing; pre-experiment reference gate, not a blocker to clerical preparation |
| Li 2024 SAT nucleator study | `Li_2024_SAT_Nucleating_Agents.pdf` | Present |
| Hua 2018 modified-SAT study | `2018_Modified_SAT_Nucleators_Thickeners.pdf` | Present |

Do not mark a missing source as reviewed merely because its DOI is recorded.
