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
Greetings from Less Than Jake these days is kind of retarded. We just come up with different ways to release a record. I’m not trying to call people out, but there are a lot of things in modern music right now that are totally bumming me out. [...] As far as releasing songs, as you get older people care less and less about what you do now. It’s more about what you’ve already done, and we’ve realized that. The term legacy act applies to our band when you refer to Less Than Jake. We do work really hard on our new songs though compared to
