| | "A new series of equations should allow scientists to design the ultimate unwettable surfaces, according to Robert Cohen and Gareth McKinley at the Massachusetts Institute of Technology, US. To illustrate the potential of their work, they created surfaces that are impervious both to water and to alkanes - and modified duck feathers to make them oil-resistant."

"So a group of researchers at the Massachusetts Institute of Technology (M.I.T.) and the Air Force Research Laboratory sought to correct that shortcoming by engineering so-called omniphobic surfaces that repel not only water—then they would be just hydrophobic—but also oil-based liquids and alcohols."
