This is an unpublished photograph from a story that I worked on for @ナショナルジオグラフィック about the influence of nature on Desgin, #Biomimetics A droplet of water, that has collected dust and dirt from the surface of a #LotusLeaf, rests on the leaf. In 1982 botanist Wilhelm Barthlott of the University of Bonn in Germany discovered in a lotus leaf a naturally self-cleaning, water-repellent surface. The secret lies in waxy microstructures and nano structures that, by their contact angle with water, cause it to bead and roll away like mercury, gathering dirt as it goes. The idea was patented by Barthlott and is called the #Lotus-effect, it has found commercial application in products like paint which is infused with Micro-bumps, the paint is reputed to repel water and resist stains for decades. @thephotosociety @Robert Clark @ナショナルジオグラフィック @instituteartist
