  1. Superomniphobic surfaces Superoleophobic Surfaces: Surfaces on which all liquids, including water, oils, alcohols, acids and bases bead up and roll-off the surface. Applications include chemical and biological protection, breathable fabrics, fingerprint resistance, drag-reduction, preventing biofouling, icephobicity. A droplet of water on a superoleophobic surface water octane Tuteja et al., Science, 2007 Tuteja et al., PNAS, 2008 Kota et al., Advanced Materials, 2012 Morphology of a superoleophobic surface. Oil droplets on a duck feather with an oleophobic coating.

  2. Membranes for oil-water separation Oil Water 125º 0º 500μm Oil Water 152º 500μm 0º Developed one of the first coatings that counter-intuitively are hydrophilic and oleophobic. Membranes based on these coatings can allow, for the first time, for the gravity based separation of all kinds of oil-water mixtures. Applications include clean up of oil-spills, waste-water treatment, emulsion break-up, and oil-extraction. This is the first-ever setup developed for the continuous separation of oil-water emulsions which utilizes only gravity. The membrane separation efficiency exceeds 99.99%. Kota et al.

  3. Membranes for oil-water separation This is one of the most energy efficient technologies for the separation of all types of oil-water mixtures. Applications include oil& gas extraction, fracking, waste-water treatment, biofuels, clean up of oil-spills, and separating a range of different commercial emulsions. Kota et al. Nature Communications, 2012
