NO can't take the strain : NO molecules are observed to preferentially dissociate near edge dislocations which originate in the bulk phase and intersect the metal surface. The effect is caused by lattice strain, a phenomenon in heterogeneous catalysis, which has been postulated for a long time and is demonstrated here on the atomic scale by calculations and STM images (see picture of two edge dislocations; black points: N atoms).
