In hopes of limiting the disastrous environmental effects of massive oil spills, materials scientists have teamed up to manufacture and test a new material, called a boron nitride nanosheet, that can absorb up to 33 times its weight in oils and organic solvents — a trait that could make it an important technology for quickly […]
