In this situation, the crystal is inclined not to stick, and abruptly slips, and continues to move smoothly across the optical lattice, similar to a caterpillar movement across a surface.

#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
and developed a device that mimics the way coral adsorbs heavy metals. Dr. Xianbiao Wang and colleagues have made coral-like nanoplates using aluminium oxide,
with the aim of adsorbing mercury from water. Aluminium oxide has previously been used to remove pollutants,
