 "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."

Researchers Create "Omniphobic" Materials That Repel Both Oil and Water
Discover, blog by Eliza Strickland, November 11, 2008

  "Researchers have long known how to create surfaces that repel water (they just had to look at a duck’s back for an example), but how to repel oily liquids was a mystery until last year, when a team of MIT chemists created a material antisocial enough to repel liquids of both kinds." materials-that-repel-both-oil-and-water/

How To Make Materials Everything-Proof
Scientific American, by John Matson, November 11, 2008

  "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."

Dirt won't stick to omniphobic material
NewScientist, by Colin Barras, November 10, 2008

  "Robert Cohen's team at the Massachusetts Institute of Technology, even had to coin a new word to describe their creation - 'omniphobic' - literally meaning it hates everything."
