Scientists reproduce the rose's 'petal effect'
— 21 Apr 2008 15:50 | ChemistryThe lotus flower is nature's 'slip n' slide,' where water beads skate along each petal's surface like liquid metal. Now, chemists reveal the ying to the lotus' frictionless yang: rose…
Scientists saved from drowning in complexities of wetting theory
— 8 Apr 2008 06:46 | PhysicsThe relationship between a thin liquid film or drop of liquid and the shape of the surface that it wets is explained with a new simplified mathematical formula published this week in…
