From: Influence of atomic site-specific strain on catalytic activity of supported nanoparticles
Atomic resolution strain behaviour of supported Pt NPs. a–l Atomic resolution strain maps within three crystallographic planes, as indicated above the NPs. The colour scale indicates variations in nearest-neighbour separations spanning from −4% (red, compressive) to 4% (blue, expansive). Strains above these thresholds are highlighted in yellow (compressive) and turquoise (expansive). Each scale bar corresponds to 3 nm. m Strain histogram from the unstrained reference area of NP 1, demonstrating <0.7% strain precision. The error bars correspond to the square root of the number of counts. n Strain histogram from the whole NP 1, vacuum surface and the NP–alumina interface
