a Variation of temperature over time under 1 sun illumination for gels with different wettability, along with infrared thermal imaging of PG and OG2. b The ammonia evaporation rates of various modified electrodes as experimentally measured or simulated from finite element modeling. c Molecular dynamics simulations of the evaporation process through pores with hydrophobic and hydrophilic modification. d Temporal evolution of hydrogen bond count at the interface of hydrophilic and hydrophobic models, along with their average values (dashed line), and adsorption energy of ammonia molecules on hydrophilic and hydrophobic chains.
