redOrbit Staff & Wire Reports - Your Universe Online Drawing inspiration from natural structures such as seashells, researchers from the McGill University Department of Mechanical Engineering have developed a new technique to create glass that will bend, but not break. “Mollusk shells are made up of about 95 percent chalk, which is very brittle in its pure form,” Professor François Barthelat explained in a statement. “But nacre, or mother-of-pearl, which coats the inner...

Recreating Nature: Scientists Copy Mother Of Pearl
2012-07-26 05:30:27

redOrbit Staff & Wire Reports - Your Universe Online Research published July 25 in the journal Nature Communications shows that scientists have for the first time copied the way mother of pearl is created. The scientists wrote in a prepared statement: "Nacre, also called mother of pearl, is the iridescent coating that is found on the inside of some mollusks and on the outer coating of pearls. By recreating the biological steps that form nacre in mollusks, the scientists were able to...

Nacre, commonly known as mother-of-pearl, is the iridescent material lining many mollusk shells. It is part of a two-layer armor system that protects the animal from predators. The brittle outer layer of the shell absorbs the initial impact, but is prone to cracking. To prevent these cracks from catastrophically propagating through the shell to the animal itself, the nacreous layer is surprisingly strong and tough, with outstanding crack arresting properties. Thus it acts as a lining to...

Biomimicry "“ technological innovation inspired by nature "“ is one of the hottest ideas in science but has yet to yield many practical advances. Time for a change. Scientists with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have mimicked the structure of mother of pearl to create what may well be the toughest ceramic ever produced.The roughness of the alumina/PMMA hybrid ceramic controls the strength of the interfaces, which is critical in...

MADISON -- While the shiny material of pearls and abalone shells has long been prized for its iridescence and aesthetic value in jewelry and decorations, scientists admire mother-of-pearl for other physical properties as well. Also called nacre ("NAY-ker"), mother-of-pearl is 3,000 times more fracture-resistant than the mineral it is made of, aragonite, says Pupa Gilbert, a physicist at the University of Wisconsin-Madison. "You can go over it with a truck and not break it - you will crumble...

Pinctada Maxima
2013-04-25 16:49:52

Pinctada maxima is a species of pearl oyster, a marine bivalve mollusk belonging to the family Pteriidae, the pearl oysters. There are two different color varieties: the White lipped oyster and the Gold lipped oyster. These bivalves are considered to be the largest pearl oysters in the world. They have a very strong inner shell layer composed of nacre, also known as “mother of pearl”. They’re significant in the cultured pearl industry as they are used to produce South Sea pearls....
