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 ...
Nelumbo nucifera, also known as Padma (Sanskrit: पद्म, romanized: Padmā, lit. 'Lotus') or Kamala (Sanskrit: कमल, lit. 'Lotus'), sacred lotus, Indian lotus, [1] or simply lotus, is one of two extant species of aquatic plant in the family Nelumbonaceae. It is sometimes colloquially called a water lily, though this more often refers ...
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 ...
Nichiren taught that chanting the title of the Lotus Sūtra in a phrase called the daimoku (Namu Myōhō Renge Kyō, "Glory to the Dharma of the Lotus Sūtra") or (Basic translation: Devotion to the Mystic Law of Cause and Effect through Sound). – was the only effective Buddhist practice in what he believed was the current degenerate age of ...

In probability theory and statistics, the law of the unconscious statistician, or LOTUS, is a theorem which expresses the expected value of a function g(X) of a random variable X in terms of g and the probability distribution of X. The form of the law depends on the type of random variable X in question. If the distribution of X is discrete and ...
The surface structure of the lotus leaf and the rose petal, as seen in Figure 9, can be used to explain the two different effects. The lotus leaf has a randomly rough surface and low contact angle hysteresis, which means the water droplet is not able to wet the microstructure spaces between the spikes. This allows air to remain inside the ...
Nelumbo nucifera Gaertn. – sacred or Indian lotus, also known as the Rose of India and the sacred water lily of Hinduism and Buddhism. [20] It is the national flower of India and Vietnam. Its roots and seeds are also used widely in cooking in East Asia, South Asia and Southeast Asia.
