Fig. 1. Typical structures obtained from three-dimensional cDFT calculations, as reported in (50).

Each figure is a view of the local density obtained by free-energy minimization of the Lennard-Jones system at a reduced temperature of T* = 0.4. The leftmost figure is a slice through a dense-solution, liquid-like, droplet; the center figure is a contour representation of an amorphous, glass-like cluster; and the rightmost figure is a contour representation of a face-centered cubic (fcc) cluster. The droplet shows the packing into shells separated by low-density regions, which is typical of confined liquids. In the other two structures, the density is localized into “atoms” separated by very low density regions.
