Accidental Discovery Transforms Cork Into an Eco-Friendly Oil Sponge

Treated cork has higher absorbance, harnesses sunlight to trap oil in minutes.Show more

Oil spills are deadly disasters for ocean ecosystems. They can have lasting impacts on fish and marine mammals for decades and wreak havoc on coastal forests, coral reefs, and the surrounding land. Chemical dispersants are often used to break down oil, but they often increase toxicity in the process.

In Applied Physics Letters, by AIP Publishing, researchers from Central South University, Huazhong University of Science and Technology, and Ben-Gurion University of the Negev used laser treatments to transform ordinary cork into a powerful tool for treating oil spills.
