Preserving surface strain in nanocatalysts

Surface strain can help increase the performance of nanocatalysts, and we have designed a new strategy to stabilize the surface strain in materials. The groups of Yimo Han and Matthew R. Jones at Rice University synthesized nanoparticles and used four-dimensional scanning transmission electron microscopy (4D-STEM) to capture an electron diffraction pattern at each scan position, which produces detailed structural information. Molecular dynamics simulations of Alberto Leonardi investigated the inhibition of dislocation nucleation due to reduced shear stress at corners.
