Coral okay

A new material that can "filter" seawater in a way that is reminiscent of how living corals behave could be used to remove mercury and other toxic heavy metals from waste water, according to research published in the Journal of Colloid and Interface Science. Xianbiao Wang of the Anhui Jianzhu University in China, and colleagues, made coral-like nanoplates using aluminum oxide, a material previously used to remove pollutants. Their nanoplates curl themselves up into a coral-like structure, which is much more effective than earlier attempts to mimic the way in which corals absorb heavy metals from water.
