PFAS-Free
Self-Pumping
Fluid Discovery.
3M is shutting down Novec by end of 2025. The two-phase immersion stack that cools GPU clusters, edge compute, and orbital electronics is about to lose its incumbent PFAS dielectric — with EPA and EU restrictions closing the door behind it.
FluxZero is the PFAS-free replacement: a Marangoni-active, self-pumping fluid family with an 89-candidate falsification screen, 18 advancing to wetlab, and 228 patent claims filed across 3 provisionals.
Where the proof comes from.
- 89-candidate global-optimum falsification screen.
- 186 MD σ measurements across 59 binary pairs (167 valid · multi-seed pooled UQ).
- 4 σ methods cross-validated: Parachor-WK, Macleod-Sugden, Meissner-Michaels, Tamura-Kurata-Odani.
- 4,806 thermodynamics work-order rows and 95 lab/vendor RFQ rows.
- 11,923 ThermoML files audited; 1,774 strict binary value rows extracted.
- 155 parsed ThermoML metadata rows · 111 unique DOI/source leads.
- 89 / 89 candidates queried against Crossref (267 metadata rows).
- DDB licensed-extraction work orders generated for follow-up.
- 18-candidate shake-flask phase map (Q2 2026).
- Pendant-drop σ on single-phase survivors.
- Dielectric loss/breakdown, flash, vapor, materials on top 3-5.
- Bare-copper pool boiling on 2-3 finalists.

PFAS Is Leaving.
Heat Flux Is Rising.
Three forcing functions converge in the next eighteen months. Every month of delay increases supply-chain exposure.
3M Market Exit
3M discontinued Novec™ and Fluorinert™ effective December 2025. $500M+ replacement demand in data-center immersion alone — cascades into heat pipes, EV thermal packs, and defense applications that depended on the same chemistry.
Universal PFAS Restriction
ECHA final opinions on the universal PFAS restriction under REACH (EC) 1907/2006 are expected 2026–2027. HFO "low-GWP" replacements (Opteon 2P50, Solstice) contain C–F bonds and face re-classification risk.
The Thermal Wall
NVIDIA B200 at 1,000 W. AMD MI325X at 750 W. Blackwell Ultra in 2027 projected 1,500–2,000 W. Air cooling died near 400 W per socket. Single-phase liquid tops out near 1,000 W because it cannot exploit phase change.
Every PFAS-free cooling fluid shipping today — Engineered Fluids EC-100, Shell S5 X, Castrol ON DC 15 — is single-phase. None self-pump. None have a Marangoni gradient. The physics forbids it in single-component fluids.
How a Fluid
Pumps Itself.
Solutal Marangoni Induction
A binary working fluid pairs a lower-σ volatile pump component with a higher-σ retained fuel component. Heat preferentially evaporates the volatile fraction at the interface, locally depleting the pump.
Gradient Formation
Local σ rises at the depleted hotspot. Cooler bulk liquid is pulled along the ∂σ/∂x gradient toward the heat source. The sign is not a styling choice; it follows the surface-stress boundary condition.
Passive Phase-Change
Arriving fluid evaporates, extracting latent heat (ΔHvap). Vapor condenses at the cold surface and re-mixes. The system is a closed thermodynamic engine in a static volume.
Self-Regulation
Higher heat load steepens the concentration and surface-tension gradients. That increases passive circulation without a controller, sensor, or mechanical pump.
/∂x
tau_s = d sigma / dx drives tangential flow at the liquid interface.
sigma is estimated from pressure-tensor anisotropy across a liquid slab.
LLE / UCST / LCST / VLE screens decide whether the mixture is physically meaningful.
loss tangent and breakdown after water saturation decide electronics suitability.
bare-copper boiling curve and CHF decide whether the fluid actually transfers heat.
Quad-Marangoni Is Not First Spend.
The mechanism stack is scientifically interesting, but it is not the next validation step. Bare-fluid phase, safety, dielectric, materials, and boiling data come first.
Solutal Marangoni
Preferential evaporation can create surface-tension gradients that pull liquid toward a hotspot.
Self-rewetting additive
Some alcohol/additive systems invert d sigma / dT in the literature; this remains composition-gated here.
Dissolved gas
Gas desorption can alter nucleation and boiling behavior; pressure and drift must be measured.
Particle / surface route
Nanoparticles or conditioned surfaces may alter thermal pathways; dielectric loss and stability are hard gates.
The Marangoni Engine,
Rendered.
Free-surface CFD and atomistic σ rendered directly from the OpenFOAM and GROMACS pipelines that drive the candidate ranking. Same code, same outputs as the published canonical inventory.
Free-Surface + Velocity Field
Atomistic Surface-Tension Estimate
Device-Geometry CFD
Free-surface velocity-field studies for sealed thermosyphon, immersion-rack, and microgravity geometries. Activates on the bare-fluid finalist for OEM-specific integration.

What Ran.
What It Decided.
Fourteen layers of computational and database evidence sit behind every candidate ranking — atomistic σ across multi-seed MD pools, four-method analytic cross-validation, ThermoML strict-value anchoring, and an EVSI sensitivity layer that points lab spend at the highest-information next measurement.

Six PFAS-Free
Candidate Architectures.
The portfolio spans six coded candidate roles — direct immersion, sealed two-phase, passive/space, and indirect-loop — covering FoMs from 3.50× to 6.36× Novec 7100. Exact compositions, ratios, and SMILES are released to qualified parties under NDA.
First-spend phase + safety screen
Manual ThermoML / DDB extraction in flight
PFAS legacy benchmarks + low-priority alternatives
Sealed direct / passive anchor
Lead direct-immersion candidate
FDA-GRAS broad fallback
Phase-proxy-favorable scout
Higher-flash low-ε fallback
Composite-FoM mechanism control
Each cooling architecture has its own dominant constraint, so the portfolio ranks per-use-case. A candidate that leads on direct immersion can be a different molecule than the one that leads on sealed passive or indirect-loop.
Direct immersion
7 coded entriesSealed two-phase
6 coded entriesPassive / space
7 coded entriesIndirect loop
4 coded entriesEVSI sensitivity ranks which next measurement maximally narrows the candidate decision. Lab spend goes where data actually changes a verdict, not where it confirms what is already known.
Lead candidates are built on commodity-grade chemistries already produced at industrial scale — orders of magnitude cheaper than legacy fluorinated dielectrics. PFAS-free formulation removes the regulatory exposure facing every fluorocarbon coolant.
Architectures.
Six coded candidate envelopes span direct immersion, sealed passive, indirect loop, and the system-multiplier stack — each backed by computational evidence and mapped to specific patent embodiments.
Low-ε sealed direct immersion
Best-in-class dielectric. Sealed two-phase architecture for high-voltage and in-package use. Covered under PROV-003 Claim 13.
Highest-FoM direct immersion
Lead direct-immersion candidate by FoM. Bayesian-discovered after the 2026-01-29 priority date; CIP filing candidate (hard-bar 2027-01-29).
GRAS-pump direct immersion
FDA-GRAS pump component for biotech-adjacent and food-contact applications. CIP filing candidate.
Broad direct / passive fallback
Best alkane-pump miscibility profile in the portfolio. Direct and passive-thermosyphon compatible.
Indirect-loop reference
Highest composite FoM in the portfolio for non-immersion architectures. Mechanism cross-check for direct-immersion physics.
System multiplier stack
Six hardware levers covered under PROV-001 and PROV-003. Each acts as a CHF multiplier on top of the bare-fluid finalist.
Six Hardware Levers.
Six Levers Above the Fluid.
The system-multiplier stack — copper foam, ultrasound, dielectric nanoparticles, biphilic surfaces, dissolved gases, and surface conditioning — sequences after the bare-fluid finalist. Each lever is covered in PROV-001 or PROV-003 and activates as a CHF multiplier on top of the validated baseline.
- ▸ Copper foam — CHF multiplier on bare-fluid finalist; PROV-001 system embodiment.
- ▸ Biphilic surface — Tuned nucleation + rewetting kinetics; PROV-001 surface embodiment.
- ▸ Al₂O₃ conditioning — Surface-energy tuning for bubble departure; PROV-001 conditioning embodiment.
- ▸ Ultrasound — Active bubble depinning; PROV-001 hardware embodiment.
- ▸ Dielectric nanoparticle — Thermal pathway enhancement at low loading; PROV-003 nanoparticle embodiment.
- ▸ Dissolved CO₂ / N₂ / Ar — Nucleation-superheat lever; PROV-003 dissolved-gas embodiment.
No One Else
Self-Pumps.
Every PFAS-free immersion fluid shipping today is single-phase — it requires a mechanical pump and cannot exploit phase change. Every two-phase fluid shipping today contains C-F bonds and faces regulatory exit. FluxZero is the only candidate stack engineered as PFAS-free and Marangoni-active — passive recirculation plus phase-change heat capacity in one binary working fluid.
| Reference fluid | Chemistry | PFAS status | Phase regime | Notes |
|---|---|---|---|---|
| FluxZero candidate stack | Marangoni-active binary | PFAS-free | Two-phase + self-pumping | Lead FoM 4.06× Novec 7100; ε = 2.05 best-in-class |
| Novec 649 / 7000 / 7100 | Fluorinated two-phase | PFAS | Two-phase | Discontinued by 3M Dec 2025 |
| Fluorinert FC-72 / FC-87 / FC-40 | Fluorinated single-phase | PFAS | Single-phase | Discontinued by 3M Dec 2025 |
| Opteon 2P50 (Chemours) | HFO two-phase | C-F bonds | Two-phase | Faces ECHA re-classification risk |
| Castrol ON DC 20 | Hydrocarbon single-phase | PFAS-free | Single-phase | No Marangoni mechanism; pump required |
| Submer SmartCoolant | Hydrocarbon single-phase | PFAS-free | Single-phase | No Marangoni mechanism; pump required |
| Shell Immersion S5 X | GTL synthetic hydrocarbon | PFAS-free | Single-phase | No Marangoni mechanism; pump required |
| Engineered Fluids EC-100 / SLIC | Synthetic hydrocarbon | PFAS-free | Single-phase | No Marangoni mechanism; pump required |
| M&I Materials MIVOLT | Synthetic ester | PFAS-free | Single-phase | No Marangoni mechanism; pump required |
Performance comparisons against commercial baselines are validated in the Q3-Q4 2026 wetlab phase: dielectric loss/breakdown after water saturation, materials compatibility, and bare-copper pool boiling on the top 2-3 finalists.
Use Cases Are Gates.
Each application has a different failure mode. The site now avoids treating one computational ranking as a universal answer.
Direct immersion
candidate only until miscibility, vapor/headspace, dielectric, materials, and boiling gates pass
Passive / thermosyphon
requires vapor-pressure, fractionation, wick/materials, and orientation testing
Indirect loop
mechanism/control space where electronics contact is not required
Space / microgravity
hypothesis only until phase, vapor, freeze/thaw, materials, and orientation tests exist
PFAS retrofit references
not PFAS-free spend targets; useful for benchmarking and legacy comparison
System multipliers
Phase 5 only after a bare-fluid winner exists
Anchored to 1,774
Strict Rows.
Computational σ ranking is anchored to 1,774 strict ThermoML binary value rows extracted from 11,923 audited files, plus 155 parsed metadata leads across 111 unique DOIs. Every candidate is queried against Crossref. Lead-candidate σ is cross-validated against four independent analytic methods.
Strict ThermoML Property Values
Metadata Leads Worth Following
Multi-seed pooled UQ across 59 binary pairs.
Parachor-WK · Macleod-Sugden · Meissner-Michaels · Tamura-Kurata-Odani.
1,774 strict binary value rows extracted across the candidate set.
Direct-immersion lead vs Novec 7100 (canonical post-T-1.2 weighting).
The proof package is multi-layered: pressure-tensor σ from multi-seed slab MD, composition-gradient Marangoni scaling, Hansen / local LLE falsification, strict ThermoML anchoring, four-method analytic σ cross-validation, VLE/fractionation work-order generation, and a kill-gated wetlab pipeline. SMILES, ratios, and exact compositions are released to qualified parties under NDA alongside the technical brief.
What Each Layer Can Decide.
The pipeline is strongest when each layer is used for the decision it can actually support. The current database work is a high-value triage layer; the first decisive experimental gate is still phase behavior.
| Layer | Can tell us | Cannot tell us |
|---|---|---|
| MD slab sigma | Ranks blends by surface-tension proxy and uncertainty | phase equilibrium, dielectric loss, breakdown, flash, vapor, boiling |
| Hansen / local LLE proxies | Flags likely miscibility failures before buying chemicals | real UCST/LCST or composition drift |
| ThermoML strict values | Anchors density, viscosity, excess volume, and activity where present | surface tension, boiling, or electronics safety for this candidate set |
| ThermoML metadata leads | Creates a DOI/source extraction queue across 18 candidates | measured values unless the paper is manually extracted |
| Crossref metadata | Confirms broad search coverage across all 89 candidates | absence of literature or absence of DDB data |
| Shake-flask / pendant-drop / dielectric | First data that can promote or kill a candidate physically | stack-level CHF or rack-scale readiness |
This is why the next spend remains cheap falsification: miscibility plus volatile-solvent headspace safety first, then pendant-drop sigma only on single-phase survivors, then dielectric/flash/vapor pressure, then bare-copper boiling.

Validation Path.
Eight sequential gates retire the cheapest failure modes first. Phase before σ. σ before dielectric. Dielectric before bare-copper boiling. Each gate is engineered so a single result can decide which candidate continues to the next stage.

Direct-immersion candidate fails if water uptake collapses dielectric margin.
EPDM, FKM, silicone, PVC, wire insulation, solder mask, TIMs, copper/nickel/aluminum coupons.

Safety fail = stop. Two-phase = demote. Sigma miss = fail MD. Electrical/materials fail = no direct immersion.
System-multiplier embodiments — copper foam, ultrasound, dielectric nanoparticles, biphilic surfaces, dissolved gas, EHD, and OpenFOAM device-geometry studies — activate as CHF multipliers on top of the validated bare-fluid finalist. Each lever compounds measured baseline performance rather than substituting for it.
Risks & Mitigation.
The validation pipeline is engineered to falsify the cheapest failure modes first. Every gate sequenced to retire a specific risk before more capital flows in — phase first, then dielectric, then materials, then bare-copper boiling.
Candidates may phase split
MD can hold a metastable mixed slab. The first decisive physical gate is 20 C and 40 C phase mapping on the 18-candidate panel.
Volatile blends may be commercially unusable
Volatile low-boiling candidates need sealed-vial, vapor-pressure, flash, and flammable-headspace controls before direct/passive language is credible.
Static epsilon is not enough
Loss tangent, breakdown after water saturation, and frequency-dependent behavior matter for electronics. These data do not exist yet.
Compatibility can kill a good fluid
EPDM, FKM, silicone, PVC, wire insulation, solder mask, TIMs, copper, nickel, and aluminum need compatibility and aging checks.
Metadata is not a measured property
ThermoML metadata creates a targeted DOI extraction queue, but extracted values must be confirmed manually. Pendant-drop wetlab σ remains the authoritative measurement for the lead candidates.
Multipliers compound, not rescue
Copper foam, ultrasound, nanoparticles, biphilic surfaces, and dissolved-gas levers act as CHF multipliers on top of the bare-fluid finalist — not as compensators for a fluid that fails phase or dielectric gates.
Value Compounds
With Validation.
Each gate compounds asset value: option agreements and early-licensee terms today, full performance-validated licensing or acquisition after Q4 2026 boiling-curve data. Engagement structures available under NDA.
Before the Meeting.
How is FluxZero different from existing PFAS-free coolants?
Every commercial PFAS-free immersion fluid shipping today (Engineered Fluids EC-100, Shell Immersion S5, Castrol ON DC, Submer SmartCoolant) is single-phase. None self-pump. None exploit a Marangoni gradient. FluxZero is a binary working fluid that creates its own surface-tension gradient under heat load — passive recirculation without a pump, plus phase-change heat capacity that single-phase fluids physically cannot deliver.
What is the strongest proof today?
186 MD σ measurements across 59 binary pairs (167 valid · multi-seed pooled UQ) with σ values cross-validated against four independent methods (Parachor-WK, Macleod-Sugden, Meissner-Michaels, Tamura-Kurata-Odani). ThermoML anchoring against 11,923 audited files. Lead direct-immersion candidate computes to FoM = 4.06× Novec 7100; indirect-loop reference reaches 6.36×. Best-in-class dielectric ε = 2.05.
How defensible is the IP?
Three provisional patent applications filed 2026-01-29 totaling 228 claims: PROV-001 (fluid system + method, 120 claims), PROV-002 (Bayesian/MD discovery engine, 50 claims), PROV-003 (PFAS-free binary keystone with microgravity and dissolved-gas embodiments, 58 claims). CIP filing packet drafted covering follow-on direct-immersion candidates, hard-bar 2027-01-29. Filing receipts and chain-of-title released to qualified parties under NDA.
What does the validation pipeline look like?
Q2 2026: 18-candidate shake-flask phase map at 20°C / 25°C / 40°C with 1h, 24h, 7d reads. Single-phase survivors advance to pendant-drop σ. Top 3-5 progress to dielectric loss/breakdown after water saturation, flash, vapor pressure, materials compatibility. Top 2-3 finalists run bare-copper pool boiling curves and CHF measurement.
What are the hard risks?
Phase stability under thermal load is the first decisive gate — MD slabs can persist as metastable mixtures. Volatile-pump candidates require sealed-headspace and flammability controls before pilot deployment. Frequency-dependent dielectric loss after water saturation is a separate gate from static ε. Materials compatibility (EPDM, FKM, silicone, solder mask, TIMs) is a deal-breaker if it fails. The validation sequence is engineered to falsify these cheaply, in order.
Is the computational stack reproducible?
Yes. Docker images (GPU NGC + CPU) ship with the dossier. `bash run_all.sh check-only` validates the full pipeline in under 5 minutes. Heavy MD reproduction is opt-in but fully automated via `reproduce_md.py` against the published canonical inventory.
Why now?
3M discontinued Novec™ and Fluorinert™ effective December 2025. ECHA universal PFAS restriction final opinions land 2026-2027. NVIDIA B200 sockets at 1,000W today; Rubin projects 1,500-2,000W. The two-phase immersion stack needs a PFAS-free, Marangoni-active replacement with measured electrical safety and validated materials compatibility — available before Novec stockpiles run out.
