Hydrolyzed haze analogs from water-rich exoplanet conditions show higher absorptivity and a high imaginary refractive index that flattens spectral features in atmospheric models.
Hycean models with a 1-bar H2 envelope, percent-level CH4 and CO, and CO2 at 10^-3 to 10^-2 reproduce the 0.8-5.2 μm JWST spectra of K2-18b.
Tholins formed at 0.125 torr have threefold lower production rate but higher density and nanoindentation hardness than those at 1 torr, while particle size, morphology, surface energy, and Young's modulus remain similar.

Feeling the Pressure: Effects of Formation Pressure on the Physical Properties of Titan Haze Analogs
Tholins formed at 0.125 torr have threefold lower production rate but higher density and nanoindentation hardness than those at 1 torr, while particle size, morphology, surface energy, and Young's modulus remain similar.
