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
Less Than Jake as landing the opening spot on Bon Jovi's North American tour. While it was neither as commercially successful as previous releases initially, the album contained singles such as "Look What Happened" (which received minor airplay on college stations) and the group's home-town anthem, "Gainesville Rock City" (which received some airtime on MTV2). Shortly after the album's recording, Derron Nuhfer left the band (going on to join Gunmoll and later Escape Grace), and Less Than Jake found a replacement in former Spring Heeled Jack saxophonist, Pete Wasilewski. To avoid the confusion provided by having two Peters within the band, the second
