A strategy for synthesizing highly dispersed metal nanoparticles can lead them to adopt a specific orientation on a substrate, which may prove useful for designing nanoparticle catalysts, researchers at Northwestern University report (Nano Lett., DOI: 10.1021/nl104263j). Subtle differences in the structure and electronic properties of one face of a metal crystal relative to another face can lead to measurable differences in the catalytic activity of nanoparticles, even though all of a crystal’s faces . . .
