title: Entropy-driven chemisorption of NO(x) on phosphotungstic acid.
abstract: Free-energy calculations indicated that the NO(x) adsorption process on heteropolyacids is entropy-driven, as more gas molecules are released than adsorbed by substitution of H(5)O(2)(+) with NO(+) species. P yellow, W light blue, O red, H pink, N small dark blue spheres.
