Salvinia Effect of Salvinia natans Featured SEM Print

Salvinia Effect of Salvinia natans

Scanning electron micrograph of leaf detail of Salvinia natans, a floating fern type plant which has superhydrophobic trichomes or hairs on the upper surface of its leaves. Each of these eggbeater shaped hairs exhibits a hydrophilic tip on the top of each hydrophobic hair. The combination of a hydrophobic surface with hydrophilic tips is called the "Salvinia Effect". These air retaining surfaces are of great interest, particularly with regards to fuel consumption when applied to ships having to overcome friction produced by the drag of water on their hulls. This drag could be reduced dramatically with the "Salvinia Effect", a layer of air between the ship's hull and the water, saving vast amounts of fuel. A suggested estimated saving of 20 million tons of oil per year for just a 10% decrease in drag for shipping alone. Magnification: x372 (x122 at 10cm wide)

Caddis Fly

Caddis Fly Scanning Electron Micrograph (SEM): Magnification x 20 (if print A4 size: 29.7 cm wide) - Caddis flies spend most of their lives as aquatic larvae in ponds and streams. The larvae construct tubular protective cases from detritus and sand grains. The adults emerge in springtime in large numbers in a mating flight; after shedding eggs into the water, the adults die

Mosquito Larvae Featured SEM Print

Mosquito Larvae

Mosquito Larvae Scanning Electron Micrograph (SEM): Magnification x40 (if print A4 size: 29.7 cm wide) - The malarial mosquito larvae live in pools and puddles; almost any standing water will do. They live by feeding on tiny organisms in the water like bacteria and protozoans. They breathe air by coming to the surface and taking air into its spiracles. They pupate, later to emarge as adult mosquitos (Anopheles sp. )
