BCT Letter 109: Forever Chemicals and the Geometry of Persistence — BCT Analysis of PFAS Stability and a Geometric Pathway to Degradation

Microplastics 2026
Michel Robert Cabrié

Summary

This paper proposes a theoretical framework called BCT geometry to explain the stability of PFAS "forever chemicals" through their resonance with a vacuum lattice, and suggests two hypothetical degradation pathways based on this geometric model. The work is speculative and non-peer-reviewed, proposing photocatalytic and enzyme-engineering approaches to break C-F bonds in both PFAS and microplastics.

Per- and polyfluoroalkyl substances (PFAS) — the "forever chemicals" — are identified as topologically protected by BCT geometry: the C-F bond vibrates at the j₁,₁ Bessel resonance mode of the OHC vacuum lattice (ν_CF ≈ 1100 cm⁻¹ = j₁,₁ × ν_BCT,mol), placing it in resonance with the vacuum condensate. Two BCT degradation pathways are proposed: (i) off-resonance photocatalysis at the j₂,₁ Bessel mode (2014 cm⁻¹) to disrupt topological protection; (ii) geometric catalyst with binding pocket ratio r_tet/r_oct = 0.5426 for C-F cleavage. Microplastic degradation via BCT void geometry enzyme engineering also proposed. Patent BCT-PFAS. Prediction #152. Zero free parameters.
