This chapter begins with a brief history of calcium phosphate biomaterials. The application of calcium phosphates for repair and reconstruction of hard tissues has been motivated by their chemical similarity to the mineral component of bones and teeth. The general structure of calcium orthophosphates can be described as a network of PO4 ...
Phosphorus was first isolated by Henning Brand in 1669. Brand used gallons of urine and named the element phosphorus meaning cold fire because of its luminescence in the dark . de Jong, in 1926, demonstrated that calcium and phosphate are the principle elements that make up bone mineral . Sixty to seventy percent of bone is composed of ...
The first known photograph was captured in 1826 when light reacted with a particular type of asphalt known as Bitumen of Judea. Since that first natural
Arabian alchemists of the 12th century may have isolated elemental phosphorus by accident, but the records are unclear. Phosphorus appears to have been discovered in 1669 by Hennig Brand, a German merchant whose hobby was alchemy. Brand allowed 50 buckets of urine to stand until they putrified and "bred worms." He then boiled the urine down to a paste …
