# NanoArc Chemistry Library

This directory contains chemistry and phase-change-material research for
NanoArc. It does not define approved ACE electrical behavior or establish a
production safety claim.

## Current working sequence

1. Rehearse and characterize `SAT/SAT-HM-001` preparation.
2. Procure and qualify the common 5 g test-cell family.
3. Establish the pure-SAT thermal baseline.
4. Screen cold-spot, chemical-nucleator, and retained-seed routes without
   combining mechanisms prematurely.
5. Feed characterized results into the cartridge proposals only after Tristan's
   review.

The broader candidate backlog is maintained in
`Proposals/Chemistry_Applications_Idea_Register.md`.

The approved benign carrier screen is maintained in
`Hydrogels/NanoArc_Hydrogel_Electrolyte_Carrier_Screen_Rev0.md`.
