To-scale snapshots from molecular dynamics simulations illustrating hot-spot formation during pore collapse. The images show pores with diameters of 60, 100, 200 and 300 nanometers, illustrating that pores larger than 20 nanometers generate hot spots with scale-invariant (independent of size) temperature distributions.
