Short summary
We followed nano-structural changes in mixtures found in urban organic aerosol emissions (oleic acid, sodium oleate and fructose) during humidity change and ozone exposure. We demonstrate that self-assembly of fatty acid nanostructures can impact water uptake and chemical reactivity, affecting atmospheric lifetimes, urban air quality (preventing harmful emissions from degradation and enabling their long-range transport) and climate (affecting cloud formation), with implications for human health.
