24 problems across 6 fields · newly named in the latest release

These 24 problems share a pattern that the collection couldn't see until it was large enough: a chemical or physical process works at lab scale but fails at production scale due to transport phenomena, catalyst lifetime, heat management, selectivity loss, or process control challenges. Distinguished from the “making one is easy. making a million is the problem” family (manufacturing system design) by binding constraint: the “making one is easy. making a million is the problem” family's challenge is production SYSTEM design — tooling, automation, QC, supply chain. the “the chemistry itself changes at scale” family's challenge is the fundamental chemistry/physics behaving differently at scale. A flow reactor's distribution becomes non-uniform across parallel channels. An enzyme loses activity under industrial temperatures. A catalyst deactivation mechanism changes at production current densities.

The chemistry works in the flask. At production scale, transport phenomena change, catalysts deactivate through different mechanisms, and selectivity is lost — because the fundamental physics behaves differently when the vessel gets bigger.

Ways this shape shows up

Catalyst lifetime/deactivation. Heterogeneous catalyst, biocatalyst, electrode, base metal — active site degradation mechanisms accelerate or change at production scale
Selectivity/phase control. Polymorph transitions, protein folding, membrane degradation — precise phase/structure control lost at scale
Transport phenomena. Flow distribution, oxygen transport, nutrient delivery — mass/heat transfer regimes change with vessel size
Feedstock variability. Soil inoculant, green solvent — process designed for pure lab inputs fails with real-world feedstock variation
Solvent/waste scaling. Peptide synthesis, fermentation purification — waste/energy costs scale super-linearly with production volume
Verification at scale. Ocean CDR — measurement methods that work in lab don't function at deployment scale
