Wishing you a productive week ahead. Feel free to continue sharing your questions and insights.

If you’re torn between H2 composites and Si3N4, I’d pick by what you can demo in about 90 days: build a small sorbent-bed prototype and track capacity fade, or run a nitriding trial with NH3 rather than N2 to skip the standard-conditions dead zone — , that step drags… For planning, I’ve had good luck with ASKCOS to flag side paths before burning material: https://askcos.mit.edu. Caveat: H2 storage has big upside but brutal validation cycles; Si3N4 gigs are steadier if you want predictable milestones.

Quick thing that helped me choose between ceramic processing and energy materials: do a ‘2-hour patent skim sprint’ for each path — take the 10 most recent patents, summarize one recurring failure mode in about 200 words, and see which write-up you enjoy. If both feel equal, pick the one where you can get customer feedback inside six months; Si3N4 tends to have steadier supply chains, while H2 composites swing more with funding cycles. Want a couple starting points for the patent search?

Choose by funding and feasibility, not vibe: with nitrides under “standard conditions” you’re fighting thermodynamics, so sanity-check Si3N4 by roughing a mechanism in RMG, and for storage benchmark against DOE targets to see if you can hit one metric in a quarter (https://www.energy.gov/eere/fuelcells/doe-technical-targets). If your lab has only a basic tube furnace, lean Si3N4; if you already have gas handling and safety sensors, storage will show progress faster. What gear do you have on the bench?

Quick step: spend 60–90 minutes in Materials Project (https://materialsproject.org) to pull phase stability and a rough defect picture for the Si3N4 target, then reality-check lab access (hot press, nitriding furnace) where you’d land — if the numbers or tool time look painful, lean toward storage materials. Small caveat: do a one-page pre-mortem asking “what kills it first?” and see which failure modes you’re excited to fix. I’d pick the path where you’d rather babysit vacuum pumps than furnace ramps.
