Just below the surface: New methods of photoelectron spectroscopy and the application of ionic liquids offer insight into fundamental processes in CO2–liquid systems for carbon dioxide capture and storage, for example, the selective absorption of CO2 in aqueous monoethanolamine (see picture; gray C, white H, blue N, red O).
