## Learnings

- The Seebeck validation route failed its first known-answer controls on TiNiSn and TiCoSb, so thermoelectric screening workflows should be treated as unvalidated until they reproduce established control materials; keep a control run active before relying on new-material predictions. See [The Seebeck route fails its first known-answer controls](https://ouro.foundation/posts/hermes/the-seebeck-route-fails-its-first-known-answer-controls) and TiNiSn ZT control (asset `01a0205d-253c-77f8-ac7c-4669fe9669ff`).
- For proposed thermoelectric materials, validate the full chain before making experimental claims: phonon stability, convex-hull distance, and transport screening can distinguish synthesizability from performance. SnP₃ showed no imaginary phonons and a 0.010 eV/atom hull distance, while predicted low lattice thermal conductivity did not translate into meaningful bulk ZT; prioritize synthesis and first measurements over optimistic performance claims. See [Making SnP₃ real: synthesis routes for a monolayer nobody has grown](https://ouro.foundation/posts/hermes/making-snp-real-synthesis-routes-for-a-monolayer-nobody-has-grown).
- For thermoelectrics outreach, prioritize laboratory and computational partners and prepare a target-specific analysis or other concrete artifact before each personalized invitation.
- POP + IIS scattering provides reliable first-order power factor estimates without full DFPT, offering physics-grounded screening to differentiate real transport prediction from generic ML, as referenced in outreach to Neophytos Neophytou (half-Heusler carrier scattering paper J. Mater. Chem. A 2026, DOI 10.1039/D5TA02998H, ElecTra code). CRM Unified Outreach Tracker (asset `019ee292-8c6c-7038-81c4-46eb601c31b6`) updated, follow-up due ~July 23.
- Orb v3 preserves Fm-3m symmetry on all Fe-based L21 Heusler compounds; P1 collapse is composition-dependent (observed in 4d/5d compounds). ALIGNN formation energy bias drops to <0.06 eV/atom for 3d transition-metal compounds. Published in [Fe-based L21 Heuslers under Ouro routes](https://ouro.foundation/posts/hermes/fe-based-l21-heuslers-under-ouro-routes-ru-free-thermoelectrics-from-parzer-et-al-2025).
- For academic researcher outreach, publishing a landscape summary or community-building post as an on-platform landing page builds credibility and provides a concrete, shareable link to include alongside personalized cold emails.
- Explored 10% self-consistency filter, Cd-doped AgSbTe₂ Pareto families, and MLIP relaxation integration within the [sysTEm thermoelectric dataset](https://ouro.foundation/posts/stevejones/wake-up-babe-new-thermoelectric-dataset-just-dropped) analysis.
- Discussed Ag₂Se-Te Pareto emergence, lattice/electronic κ split, and crystal structure clustering of Pareto-optimal materials in thermoelectric optimization. [sysTEm thermoelectric dataset post](https://ouro.foundation/posts/stevejones/wake-up-babe-new-thermoelectric-dataset-just-dropped)

## Facts

- Michael Parzer's outreach is now sent and logged, linking the [Fe-based L21 Heusler routes post](https://ouro.foundation/posts/hermes/fe-based-l21-heuslers-under-ouro-routes-ru-free-thermoelectrics-from-parzer-et-al-2025) and the August MLIP symmetry recheck; CRM contact Parzer (asset `2fcd13dd-aaa0-4087-88d7-968b34229301`) is marked sent.
- Jonathan Alaria was contacted about the [phase-transition thermal-expansion atlas](https://ouro.foundation/posts/hermes/how-a-phase-transition-bends-thermal-expansion-an-atlas-from-cod-multi-temperature-series), focused on his group's GaMo4Se8 COD neutron series and the 65–100 K expansion-suppression window.
- For Ricardo Grau-Crespo outreach, CraTENet weights are the next actionable inquiry; any thermoelectrics team-lead invitation remains subject to Matt's decision. See call recap post (asset `019fa488-758b-7d13-9fc5-43d85a652d39`).
- Fe₂TiSi is the direct Fe-analog of Ru₂TiSi for cross-cycle thermoelectric comparison. Fe-based L21 Heusler set (Fe₂VAl, Fe₂TiAl, Fe₂VSi, Fe₂TiSi, Fe₂VGe) sourced from Parzer et al. 2025, with CIFs generated and published in [Fe-based L21 Heuslers under Ouro routes](https://ouro.foundation/posts/hermes/fe-based-l21-heuslers-under-ouro-routes-ru-free-thermoelectrics-from-parzer-et-al-2025).
- Michael Parzer ([michael.parzer@tuwien.ac.at](mailto:michael.parzer@tuwien.ac.at) / [parzer@ifp.tuwien.ac.at](mailto:parzer@ifp.tuwien.ac.at), TU Wien) is a thermoelectrics outreach prospect specializing in Fe-based L21 Heuslers (Fe₂VAl). Outreach email drafted 2026-07-11 referencing specific ALIGNN 3d-vs-4d accuracy finding; awaiting @mmoderwell approval before sending.
- Jose J. Plata Ramos ([jose.plata@uca.es](mailto:jose.plata@uca.es), U Cádiz) is a thermoelectrics outreach prospect who can authorize hosting the DL-skutterudite zT model on Ouro. Peter Franz Rogl provided a warm referral to Plata. Outreach email sent 2026-06-22; awaiting Plata's reply.
- Key thermoelectrics outreach prospects include Tiejun Zhu, Gerda Rogl, Philippe Jund, Johannes de Boor, Snyder, and Yan He. Created on-platform landing pages [Where the thermoelectrics team stands](https://ouro.foundation/posts/hermes/where-the-thermoelectrics-team-stands) and [Thermoelectrics: where the field actually stands](https://ouro.foundation/posts/hermes/thermoelectrics-where-the-field-actually-stands) to establish credibility before emails. Initial personalized emails were sent to Zhu, Rogl, Jund, and de Boor referencing their specific 2025-2026 publications.
