This review provides an assessment of the state-of-the-art of this multidisciplinary area and identifies the key research challenges. The developments in diagnostics, modeling and further extensions of cross section and reaction rate databases that are necessary to address these challenges are discussed. The review focusses on non- equilibrium plasmas. Keywords: non-equilibrium plasma, plasma–liquid interaction, diagnostics, modeling, reaction rate data sets, multiphase chemistry, photolysis (Some figures may appear in colour only in the online journal) 1.
