and push the ion crystal over the lattice, and to squeeze and stretch the ion crystal, in a motion similar to an accordion,
to modify the atomic spacing. They observed that the two surfaces underwent maximum friction, similar to two complementary Lego bricks,
when atoms in the ion crystal were spaced normally at intervals equaling the optical lattice spacing.

#Coral-Like Nanoplates Help Remove Toxic Heavy metals from Water A new material that mimics coral could help remove toxic heavy metals like mercury from the ocean,
Toxic heavy metal ions like mercury, lead and arsenic are released into the water through human activity, including manufacturing and industrial processes.
One major source of toxic metal contamination is the ocean. When mercury pollutes the water
Heavy metals are also toxic to corals: even at low concentrations, small amounts of heavy metal pollution can kill corals.
This heightened toxicity is due to coral being very efficient at collecting, or adsorbing, heavy metals. The researchers behind the new study have taken inspiration from this
