Salvinia effect The describes the permanent stabilization of an air layer upon a hierarchically structured surface submerged in water. Based on biological models (e.g. the floating ferns "Salvinia", backswimmer "Notonecta"), biomimetic Salvinia-surfaces are used as drag reducing coatings (up to 30% reduction were previ...

Salvinia effect A silvery shine, due to the reflection of light at the interface of air and water, is visible on the submerged surfaces. Long lasting air layers also occur in aquatic arthropods which breathe via a physical gill (plastron) e. g. the water spider ("Argyroneta") and the saucer bug ("Aphelocheirus") Air la...

Salvinia effect These structures resemble microscopic eggbeaters and are therefore referred to as “eggbeater trichomes”. The entire leaf surface, including the hairs, is covered with nanoscale wax crystals which are the reason for the water repellent properties of the surfaces. These leaf surfaces are therefore a class...

Salvinia effect The Salvinia effect, described here, most likely plays an essential role in its ecological success; the multilayered floating plant mats presumably maintain their function of gas exchange within the air-layer. The defines surfaces which are able to permantently keep relatively thick air layers as a resu...

Salvinia effect Compartments with sealed edges are also important for technical applications. The working principle is illustrated in for the Giant Salvinia. The leaves of "S. molesta" are capable of keeping an air layer on its surfaces for a long time when submerged in water. If a leaf is pulled under water, the leaf ...

Salvinia effect With increasing negative pressure the bubble grows and can detach from the surface. The air bubble rises to the surface and the air layer decreases until it vanishes completely. In case of the surface with hydrophilic anchor cells (right) the water is pinned to the tips of every structure by the hydroph...

Salvinia effect If water flows over a smooth solid surface, the velocity at the surface is zero due to the friction between water and surface molecules. If an air layer is situated between the solid surface and the water the velocity is higher than zero. The lower viscosity of air (55 times lower than the viscosity of ...

Madeleine M. Joullié (born March 29, 1927) is a French-born American organic chemist. She was the first woman to join the University of Pennsylvania chemistry faculty as well as the first female organic chemist to be appointed to a tenure track position in a major American university. She was one of the first affirmati...
