On the impact of capillarity for strength at the nanoscale [PDF]
Nature Communications, 2017 AbstractThe interior of nanoscale crystals experiences stress that compensates for the capillary forces and that can be large, in the order of 1 GPa. Various studies have speculated on whether and how this surface-induced stress affects the stability and plasticity of small crystals.
