Tracking all-vapor instant gas-hydrate formation and guest molecule populations: A possible probe for molecules trapped in water nanodroplets

Popis výsledku v původním jazyce

Quantitative Fourier-transform infrared spectra for low-temperature (160?200 K) aerosols of clathrate-hydrate nanoparticles that contain large-cage catalysts and small-cage nonpolar guests have been extended to a broad range of vapor compositions and sampling conditions. The data better reveal the stages by which room-temperature vapor mixtures, when cooled below 220 K, instantly generate aerosols with particles composed exclusively of the corresponding clathrate hydrates. In particular the quantitativedata help relate the nature of the hydrates that form to the composition of the aqueous nanodroplets of the first stages of the rapid transition from the all-vapor mixture. The overall transition from an all-vapor mixture to ?gas-hydrate nanocrystals isa multistage one that has been characterized as homogeneous nucleation and growth of solution nanodroplets (240 K) followed by nucleation and growth of the gas-hydrate particles (220 K); all occurring within a subsecond that follows puls
