Development
The beginning of Chameleon Coating was not always nanoscaled until recent developments in nanoengineering. Before the use of nano films (coatings), the films used to provide the beneficiary aspects of the coating would break down easier and faster due to consistent wear and tear. The use of the nano thin films helped control dislocating formation of the film and helped reduce the shear rate( rate at which the film deteriorated) due to abrasion and wear several folds over. The term “chameleon coating” was used in analogy to the actual coating of a chameleon where the coat of a chameleon is able to adapt to its environment as a defense mechanism to avoid predators and increase its chances of survival. The use of diamond-like carbons or DLC for short is generally one of the nano films used to inhibit abrasion. A possible nano film that could be used to counteract temperature changes are the pure metals Ag and Au (Silver and Gold). Silver and Gold can withstand high temperatures and remain soft which is desirable for coating properties. Using a lattice matrix ( a template for the coating using the basket weave design), nano engineers are able to utilize properties of the DLC’s and pure metals to make chameleon coatings more adaptable at even more varied environments.

Famous quotes containing the word development:
“This was the Eastham famous of late years for its camp- meetings, held in a grove near by, to which thousands flock from all parts of the Bay. We conjectured that the reason for the perhaps unusual, if not unhealthful development of the religious sentiment here, was the fact that a large portion of the population are women whose husbands and sons are either abroad on the sea, or else drowned, and there is nobody but they and the ministers left behind.”
—Henry David Thoreau (1817–1862)
“As long as fathers rule but do not nurture, as long as mothers nurture but do not rule, the conditions favoring the development of father-daughter incest will prevail.”
—Judith Lewis Herman (b. 1942)
“The work of adult life is not easy. As in childhood, each step presents not only new tasks of development but requires a letting go of the techniques that worked before. With each passage some magic must be given up, some cherished illusion of safety and comfortably familiar sense of self must be cast off, to allow for the greater expansion of our distinctiveness.”
—Gail Sheehy (20th century)
