Fish and Flowers Inspire Diving Goggle Material

Fish and Flowers Inspire Diving Goggle Material | Biomimicry | Scoop.it
From www.rsc.org - April 21, 2015 3:53 PM

"Light scattering means that many synthetic oil-repellent surfaces are opaque, limiting their use. A transparent, oil-repellent surface would have applications in biology and underwater optics, including in diving goggles and cameras. Now, Feng Chen’s research group at Xi’an Jiaotong University has developed such a material. Fish repel oil by trapping water within their scales to create a self-cleaning, oil-repellent coat and prompted part of the idea behind the work. Chen’s other brainwave was triggered by Diphylleia grayi – also known as the skeleton flower."

Waterproof Surface is 'Driest Ever'

Waterproof Surface is 'Driest Ever' | Biomimicry | Scoop.it
From www.bbc.co.uk - November 21, 2013 2:57 AM

"US engineers have created the "most waterproof material ever" - inspired by nasturtium leaves and butterfly wings. The new "super-hydrophobic" surface could keep clothes dry and stop aircraft engines icing over, they say."

Butterfly-Wing Wafers to Clad Iridescent Buildings

Butterfly-Wing Wafers to Clad Iridescent Buildings | Biomimicry | Scoop.it
From www.newscientist.com - October 18, 2012 3:19 AM

Now no one can say butterflies are all style and no substance. This might look like a pretty lily pad but it is actually a wafer created with lasers to mimic the iridescent colours of a butterfly's wings. For extra credit, Shu Yang at the University of Pennsylvania in Philadelphia, who led the project, also made the wafer water-repellent - another property of butterflies' wings, which helps them fly through rain.

Quenching the World's Water and Energy Crises, One Tiny Droplet at a Time

Quenching the World's Water and Energy Crises, One Tiny Droplet at a Time | Biomimicry | Scoop.it
From phys.org - July 24, 2014 12:29 PM

"In the Namib Desert of Africa, the fog-filled morning wind carries the drinking water for a beetle called the Stenocara. iny droplets collect on the beetle's bumpy back. The areas between the bumps are covered in a waxy substance that makes them water-repellant, or hydrophobic (water-fearing). Water accumulates on the water-loving, or hydrophilic, bumps, forming droplets that eventually grow too big to stay put, then roll down the waxy surface. [...]  More than a decade ago, news of this creature's efficient water collection system inspired engineers to try and reproduce these surfaces in the lab. Small-scale advances in fluid physics, materials engineering and nanoscience since that time have brought them close to succeeding."

Controlling Wettability: 'Sticky tape' for Water Droplets Mimics Rose Petal

Controlling Wettability: 'Sticky tape' for Water Droplets Mimics Rose Petal | Biomimicry | Scoop.it
From www.sciencedaily.com - September 19, 2013 6:16 AM

A new nanostructured material may lead to surfaces that stay dry forever, never need cleaning and are able to repel bacteria and even prevent mold and fungi growth. "The newly discovered material uses raspberry particles -- so-called because of their appearance -- which can trap tiny water droplets and prevent them from rolling off surfaces, even when that surface is turned upside down," said Dr Andrew Telford from the University's School of Chemistry and lead author of the research recently published in the journal, Chemistry of Materials. The raspberry particles mimic the surface structure of some rose petals.

Lotus Leaf Inspires Fog-free Finish for Transparent Surfaces

From www.sciencenewsline.com - August 2, 2012 8:27 AM
Inspired by the water-repellent properties of the lotus leaf, a group of scientists in China has discovered a way to impart a fog-free, self-cleaning finish to glass and other transparent materials.

An Optical Display Made of Water and Air and Inspired by the Lotus Flower

An Optical Display Made of Water and Air and Inspired by the Lotus Flower | Biomimicry | Scoop.it
From news.discovery.com - June 21, 2012 9:21 AM

[...] researchers at Aalto University in Finland [...] in conjunction with the Nokia Research Center and University of Cambridge [...] discovered an innovative way to write and display information using only air and water. Not only that, they've drawn inspiration from the water-repelling flower that's an emblem of enlightenment and non-attachment: the Sacred Lotus.
