A water drop on a lotus surface showing contact angles of approximately 147°. The lotus effect refers to self-cleaning properties that are a result of ultrahydrophobicity as exhibited by the leaves of Nelumbo, the lotus flower. [1] Dirt particles are picked up by water droplets due to the micro- and nanoscopic architecture on the surface ...
Ultrahydrophobicity. A drop on a lotus surface, with a contact angle of greater than 146°. A water droplet falling onto a superhydrophobic, elastic surface. In chemistry and materials science, ultrahydrophobic (or superhydrophobic) surfaces are highly hydrophobic, i.e., extremely difficult to wet. The contact angles of a water droplet on an ...
Wilhelm Barthlott (born 1946 in Forst, Germany) is a German botanist and biomimetic materials scientist. His official botanical author citation is Barthlott. Barthlott's areas of specialization are biodiversity (global distribution, assessment, and change in biodiversity) and bionics/ biomimetics (in particular, superhydrophobic biological ...
A superhydrophobic coating is a thin surface layer that repels water. It is made from superhydrophobic (also known as ultrahydrophobic) materials, and typically cause an almost imperceptibly thin layer of air to form on top of a surface. Droplets hitting this kind of coating can fully rebound. [1][2] Generally speaking, superhydrophobic ...
Trypophobia. Trypophobia is an aversion to the sight of repetitive patterns or clusters of small holes or bumps. [3][4][5] It is not officially recognized as a mental disorder, but may be diagnosed as a specific phobia if excessive fear and distress occur. [1][4] Most affected people experience mainly disgust when they see trypophobic imagery. [4]

The Lotos-Eaters is a poem by Alfred Tennyson, describing a group of mariners who, upon eating the lotos, are put into an altered state and isolated from the outside world. The Lotus Eater is a short story by W. Somerset Maugham about a man who goes to live a life of indolence on the island of Capri. British romantic composer Hubert Parry wrote ...
The lotus is often confused with the true water lilies of the genus Nymphaea, in particular N. caerulea, the "blue lotus."In fact, several older systems, such as the Bentham & Hooker system (which is widely used in the Indian subcontinent), refer to the lotus by its old synonym, Nymphaea nelumbo.
