Tiny Submarines Gather Oil
To remove oil and other organic contaminants from water, scientists may someday deploy submarines—microsubmarines. Tubular microscale engines zip through solution by converting hydrogen peroxide fuel into oxygen bubbles that they then expel for propulsion. By giving these tiny swimmers a hydrophobic monolayer coating of long-chain alkanethiols, researchers have transformed them into oil-gathering microsubmarines that are capable of capturing, transporting, and separating oil contamination from water (ACS Nano, DOI: . . .
