New water treatment method is based on a sea creature

The video discusses the limitations of conventional coagulants like aluminum sulfate in removing small dissolved contaminants from water. Researchers from Yale and Peking University developed a nanocoagulant inspired by actinia to address this issue. The nanocoagulant features a core-shell structure that turns inside out in water, effectively trapping larger particles with its shell and capturing smaller dissolved ones with its core.

What types of contaminants can the nanocoagulant remove in a single step?

Describe the core shell structure of the nanocoagulant and its function.
