It is marketed for use in hospitals and other places with a relatively high potential for bacteria to spread and cause infections. [1] The inspiration for Sharklet's texture came through analysis of the texture of shark skin, which does not attract barnacles or other biofouling, unlike ship hulls and other smooth surfaces. The texture was later ...
One class of biomimetic antifouling coatings is inspired by the surface of shark skin, which consists of nanoscale overlapping placoid scales that exhibit parallel ridges that effectively prevent sharks from becoming fouled even when moving at slow speeds. The antifouling qualities of the shark skin-inspired designs appear highly dependent upon ...
Notable examples of these natural structures include: honeycomb structure of the beehive, strength of spider silks, bird flight mechanics, and shark skin water repellency. [2] The etymological roots of the neologism "biomimetic" derive from Greek, since bios means "life" and mimetikos means "imitative". [citation needed]
To demonstrate the use of micro-vascular networks for autonomic healing, researchers developed a microvascular coating–substrate architecture that mimics human skin. [76] Bio-inspired self-healing structural color hydrogels that maintain the stability of an inverse opal structure and its resultant structural colors were developed. [ 77 ]
Molded and laser-ablated shark skin replicas have been fabricated, and shown to be oleophobic in water. The molded replicas use a negative made of polyvinylsiloxane dental wax and the positive replica was made of epoxy. [55] These replicas have also shown that the structure of shark skin reduces the fluid drag caused by turbulent flow. The ...
A young competitive swimmer is back in the pool after having her feet recontructed using shark cartilage and skin following an accident. Isabela Juricevic, from Indiana, was injured when a car ...
Indigo carmine, or 5,5′-indigodisulfonic acid sodium salt, is an organic salt derived from indigo by aromatic sulfonation, which renders the compound soluble in water. Like indigo, it produces a blue color , and is used in food and other consumables , cosmetics, and as a medical contrast agent and staining agent; it also acts as a pH indicator .
Shark Night 3D. Let's get one thing out of the way: Shark Night 3D is a ridiculous movie. There are sharks chasing jet skis and just a whole of dumb college kids doing dumb things, played, of ...
