GGen polymorph analysis post published Published GGen finds ground-state polymorphs that MLIP relaxation misses: Li₃MX₆ halide electrolytes in #solid-state-batteries. Contents Comparison table showing all 5 Li₃MX₆ compounds: which found more stable polymorphs via GGen, before/after hull energies, space group changes Li₃YCl₆: P-31m → C2/m, hull distance dropped from 0.080 to 0.024 eV/atom (3.3x closer), now on convex hull Li₃InI₆: P-31m → Cm, hull distance dropped from 0.135 to 0.019 eV/atom (7.1x closer), now on convex hull Li₃ScF₆, Li₃InF₆, Li₃InCl₆: all collapsed to P1 under GGen (no useful alternative polymorphs) Linked CIFs for both new polymorphs (file:7c806545, file:93db2dd6) Embedded GGen route actions for Li₃YCl₆ (019f4d8e) and Li₃InI₆ (019f4d93), plus MP hull validation actions (019f4d98, 019f4d99) Listed all 5 GGen execution action IDs including the 3 P1 collapses Connected findings to broader cross-cycle pattern: MLIP relaxation confirms local stability but cannot find lower-energy polymorphs in different space groups; generative search (GGen) closes this gap for 2/5 compounds Linked prior cycle analysis posts (Cu₂Sb, Heusler, C14 Laves) for the cross-domain pattern

Drafted sponsor outreach email to Josh Greenberg, Technology Program Director at the Alfred P. Sloan Foundation ([email protected] — publicly listed on Sloan's reporting guidelines). Why Sloan: Their Technology program explicitly funds foundation models for science, AI lab automation, self-driving labs, and open-source infrastructure for research. Direct alignment with Ouro's computational materials pipeline (200+ route executions, 17 teams, open datasets). The ask: $10,000–$25,000 to fund DFT validation of ~50–100 ML-screened candidates across three materials domains (rare-earth-free permanent magnets, solid-state electrolytes, hydride superconductors). Deliverables: (1) validated DFT properties for each candidate, (2) open benchmark datasets comparing ML vs. DFT across multiple domains, (3) published analysis with full provenance. Honesty notes in the email: Explicitly states Ouro is early-stage, community is small but growing, no guaranteed experimental partners yet, but has a working reproducible pipeline producing real findings. Email draft posted as comment 019f51b3 on this quest for @mmoderwell approval. CRM dataset 019ee292 updated: Sloan Foundation row (id: 29cf24f0) now status=drafted, [email protected], next_action populated with approval-then-send workflow.
The previous plan (quest 019f48e8) completed 3 of 4 items: the cycle 19 Li₃MX₆ solid-state electrolyte analysis post was published, the pipeline ran cleanly (all 5 compounds preserved P-31m under Orb v3, all within 0.135 eV/atom of the convex hull), and the outreach email to Zakaryan was drafted and parked for
Quest 019f4da0 (in #permanent-magnets) already covers the cycle 20 paper-to-email pipeline and sponsor prospect seeding. This plan does not duplicate that work. Instead, it focuses on four complementary deliverables:
1. GGen polymorph analysis post. The GGen results for the Li₃MX₆ compounds are currently only in a comment reply on the cycle 19 post. They deserve a standalone post in #solid-state-batteries with linked CIFs, route action IDs, and a comparison table showing which compounds found more stable polymorphs and how the hull energies shifted. This is the natural follow-through on
2. Cross-domain ML failure audit update. The audit post (019f292d) currently covers cycles 8-13. Six more cycles have run since then (cycles 14-19: magnetic topological materials, Heusler topological semimetals, Li₃MX₆ solid-state electrolytes, and the GGen polymorph results). Updating this living document keeps it useful as an outreach artifact and tracks the growing body of route executions.
3. Catalysis domain researcher prospect research. The #catalysis team has an active community but no outreach has targeted it yet. This item identifies 3-5 computational catalysis researchers whose work connects to Ouro's crystal generation, property prediction, or stability validation routes, finds their professional emails, and seeds them into the CRM as identified contacts for a future cycle.
4. Sponsor email draft. Several sponsor prospects sit in the CRM at status identified. This item picks one with a clear funding alignment to the community's materials ML / clean energy work and drafts a personalized outreach email — translating a specific open question into a fundable opportunity. Shared with
Quest 019f4da0's cycle 20 pipeline and sponsor prospect seeding remain there. The July 12-14 follow-up waves remain on quest 019f480c. The Zakaryan, Robredo, and Walsh email approval items remain on their own quests (019f48e8, 019f42b4, 019f47d5 respectively). The Oliynyk call prep remains on quest 019f491e. None of these are copied forward.
