How fish scales and magnetism could mop up oil spills

摘要

Discovering what makes oil bond to some surfaces and not others could be the key to environmental clean-ups. Researchers at the University of Wollongong's Institute for Superconducting and Electronic Materials (ISEM) with their partners at Beihang University in China have demonstrated two novel methods of controlling the movement of droplets of oil within other liquids using magnetic forces.
