Functional Surfaces Inspired by Salvinia Leaves Recent findings from the aquatic plant provide novel approaches for application of superhydrophobic surfaces. In article number 2100079, Limei Tian, Huichao Jin, and co-workers summarize recent developed advanced techniques duplicating complex eggbeater structures leaves. The review also discusses engineering applications future development Salvin...

Salvinia leaves represent an extraordinary example of how nature found a strategy for the long term retainment of air, and thus oxygen, on a surface, the so-called ‘Salvinia effect’, thanks to the peculiar three-dimensional and hierarchical shape of the hairs covering the leaves. Here, starting from the natural model, we have microfabricated hairs inspired by those present on the Salvinia moles...

Some plants and animals feature superhydrophobic surfaces capable of retaining a layer of air when submerged under water. Long-term air retaining surfaces (Salvinia-effect) are of high interest for biomimetic applications like drag reduction in ship coatings of up to 30%. Here we present a novel method for measuring air volumes and air loss under water. We recorded the buoyancy force of the air...

Cyrtobagous salviniae Calder and Sands (Coleoptera: Curculionidae) is a successful biological control agent of aquatic weeds suppressing species like giant salvinia, Salvinia molesta D.Mitch. (Salviniales: Salviniaceae), in at least 15 countries over 3 continents (Julien et al. 2002). There are at least 2 ecotypes of this insect; the smaller Florida ecotype found on common salvinia, S. minima B...

Bioinspired functional surfaces are attracting increasing interest in surface engineering, mostly the field of wettability. The Salvinia-effect is a remarkable example superficial air retention and drag force reduction caused by selective chemical coating (super-hydrophobic wax hydrophilic dead cells) peculiar 3D hierarchical morphological structures. replication Salvinia-like patterns at micro...

The main goal of this research was to quantify the concentrations of total and ammonium N, nitrate, total and soluble P in the water in the presence of Eichhornia crassipes and Salvinia auriculata, which were submitted to two different photoperiods in a 24 hours incubation period in the laboratory. The macrophytes were incubated in plastic vials of approximately 1.5 litters, with a previously p...
