Casimir–van der Waals Atomic Layer Deposition Monitors for Environmental Compliance Data

PROBLEM: Compliance monitors with ALD-coated sensing surfaces depend on a coating whose thickness governs both chemical binding and dispersion-force effects, yet compliance workflows often record only the monitor's output and not its coating history. Two monitors with different ALD histories can then produce irreconcilable records for the same water. The workflow needs coating provenance bound to every reading.

SOLUTION: IBM Cloud Ideas would provide a capability for governing ALD compliance monitors in which each reading is linked to its coating recipe, DFT binding model, Casimir/van der Waals dispersion-force model, and isotherm validation. The capability would version the model with each coating change, require regeneration and reuse accounting, and keep deposition and regeneration energy attached to the monitor record. It supports auditable compliance monitoring without certifying the data.

EVIDENCE BASIS: Casimir/van der Waals dispersion forces are DOCUMENTED: quantum-fluctuation forces between uncharged surfaces at nanoscale; Casimir measured 1997 (Lamoreaux). DFT (Hohenberg–Kohn 1964, Kohn–Sham 1965, Nobel 1998) predicts which surface groups bind which species. Biosorption is validated via batch isotherms, qe = (C0 − Ce)V/m, with Langmuir and Freundlich isotherms as textbook models. Source: Lamoreaux 1997 Casimir measurement and textbook DFT and biosorption isotherm literature as summarised in the batch method.
