By manipulating chemical gradients in a beaker of fluid, the behavior of crystal growth can be controlled, creating precisely tailored structures – “flowers” at the scale of microns – that bloom in a beaker.

Though these minuscule sculptures don't resemble the cubic or jagged forms normally associated with crystals, they “bloom” from the surface of a submerged glass slide, assembling themselves one molecule at a time.

The precipitation of the crystals depends on a reaction of compounds that are diffusing through a liquid solution. The crystals grow toward or away from certain chemical gradients as the pH of the reaction shifts back and forth. The conditions of the reaction dictate whether the structure resembles broad, radiating leaves, a thin stem, or a rosette of petals.

Impressive, but who's actually paying to research this stuff? Like seriously, is this really that important to study Neutral Face
