A problem family — different problems, same issues

the chemistry itself
changes at scale

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

These 24 problems share a pattern that became visible only once the collection was large. A chemical or physical process works at lab scale and fails at production scale, because of how heat and material move, how long the catalyst lasts, loss of selectivity, or difficulty controlling the process. In the “making one is easy. making a million is the problem” family the challenge is designing the production system: tooling, automation, quality control, supply chain. Here the chemistry or physics itself behaves differently at scale. Flow through a reactor becomes uneven across parallel channels. An enzyme loses activity at industrial temperatures. A catalyst fails by a different mechanism at production current densities.

The chemistry works in the flask. At production scale heat and material move differently, catalysts fail by different mechanisms, and selectivity is lost.

Ways this family shows up

Catalyst lifetime. The ways a catalyst degrades speed up or change at production scale
Control of phase and structure. Precise control of crystal form, protein folding, or membrane structure is lost at scale
Movement of heat and material. Flow, oxygen transport, and nutrient delivery change with the size of the vessel
Variable raw material. A process designed for pure lab inputs fails with the variation in real raw material
Solvent and waste. Waste and energy costs grow faster than production volume
Checking at scale. Measurement methods that work in the lab don't work at the scale of deployment
