The lotus roots are planted in pond or river bottom soil, while the leaves float on the water's surface or are held well above it. The leaf stalks (petioles) can be up to 200 cm (6 ft 7 in) long, allowing the plant to grow in water to that depth. [ 8 ]
The leaves of Nelumbo are highly water-repellent (i.e. they exhibit ultrahydrophobicity) and have given the name to what is called the lotus effect. [3] Ultrahydrophobicity involves two criteria: a very high water contact angle between the droplet of water and the leaf surface, and a very low roll-off angle. [ 4 ]
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, which minimizes the droplet's adhesion to that surface.
American lotus is an emergent aquatic plant. It grows in lakes and swamps, as well as areas subject to flooding. The roots are anchored in the mud, but the leaves and flowers emerge above the water's surface. The petioles of the leaves may extend as much as 2 m (6.6 ft) and end in a round leaf blade 33–43 cm (13–17 in) in diameter. Mature ...
Lotus, a latinization of Greek lōtos (), [2] is a genus of flowering plants that includes most bird's-foot trefoils (also known as bacon-and-eggs) [3] and deervetches. [4] Depending on the taxonomic authority, roughly between 70 and 150 species are accepted, all legumes; American species formerly placed in the genus have been transferred to other genera.
Lotus identifies various plant taxa: Nelumbo, a genus of aquatic plants with showy flowers Nelumbo nucifera, the Sacred or Indian lotus; Nelumbo lutea, the American or yellow lotus; Certain species of Nymphaea (water lilies or Egyptian lotuses): Nymphaea caerulea, also known as blue lotus; Nymphaea lotus, white lotus or sacred lotus
Active recent research on superhydrophobic materials might eventually lead to industrial applications. Some attempts at fabricating a superhydrophobic surface include mimicking a lotus leaf surface, namely the two-tiered characteristic. This requires micro-scale surfaces with typically nanoscale features on top of them.
Lotus leaf tea, called yeonnip-cha (연잎차 [jʌn.nip̚.tɕʰa]) in Korean, is a tea made from young leaves of lotus. [1] Leaves for lotus tea are often heat-treated (either by steaming or roasting) before being dried. [1]
