Contact angle a contact angle of 0°. This is often the case for water on bare metallic or ceramic surfaces, although the presence of an oxide layer or contaminants on the solid surface can significantly increase the contact angle. Generally, if the water contact angle is smaller than 90°, the solid surface is considered hydrophilic and if the water contact angle is larger than 90°, the solid surface is considered hydrophobic. Many polymers exhibit hydrophobic surfaces. Highly hydrophobic surfaces made of low surface energy (e.g. fluorinated) materials may have water contact angles as high as ~120°. Some materials with highly rough surfaces
While(1 Is Less Than 2) While(1 Is Less Than 2) While(1<2) (stylized as while(1<2); pronounced "while one is less than two") is the seventh studio album by Canadian electronic music producer Deadmau5, released on June 17, 2014 by Mau5trap, Virgin EMI and Astralwerks, his only album to be released by the latter. The album is a departure from the bass-heavy, upbeat template of his previous work, instead foraying in a more experimental direction, with tones of downtempo and ambient music.
