3D-printed machines that manipulate microscopic objects using capillary forces
By harnessing capillary forces, 3D-printed machines with cross-sections that vary by height can move floating objects programmatically in two dimensions and even braid filaments without physical contact.

A cloak of liquidity
Droplets of a liquid alloy on a silicon surface can rearrange the surface atoms so that they mimic the short-range ordering of atoms in the alloy. Remarkably, this effect inhibits freezing of the droplets.
