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) 3.5/5 stars. Rolling Stone, however, was more critical of the album stating "Deadmau5 has turned from an electro-house polymath into the world's most unnecessary Nine Inch Nails tribute act" giving it 2 stars out of 5. Slant Magazine was equally critical saying "Deadmau5 enters the fray with the advantage of deeply diminished expectations. His latest, While(1<2), comfortably clears the bar set by his contemporaries, and that would be impressive if the bar wasn't buried underground" also awarding it 2 stars. Note While(1 Is Less Than 2) While(1<2) (stylized as while(1<2); pronounced "while one is less than two") is the seventh
