Carbon films are a type of fossil, or preservation. They are thin film coatings which consist predominantly of the chemical element carbon, which include plasma polymer films, amorphous carbon films (diamond-like carbon, DLC), CVD diamond films as well as graphite films. The soft tissues of organisms are made largely of organic carbon compounds. Sometime fossils contain only carbon. Fossils usually form when sediments bury a dead organism. As sediment piles up, the organism's remains are subjected to pressure and heat. These conditions force gases and liquids from the body. A thin film of carbon residue is left, forming a silhouette of the original organism called a carbon film.
Famous quotes containing the word film:
“Is America a land of God where saints abide for ever? Where golden fields spread fair and broad, where flows the crystal river? Certainly not flush with saints, and a good thing, too, for the saints sent buzzing into man’s ken now are but poor- mouthed ecclesiastical film stars and cliché-shouting publicity agents.
Their little knowledge bringing them nearer to their ignorance,
Ignorance bringing them nearer to death,
But nearness to death no nearer to God.”
—Sean O’Casey (1884–1964)
