Hence the name density functional theory comes from the use of functionals of the electron density. DFT is among the most popular and versatile methods available in condensed-matter physics, computational physics, and computational chemistry.n general, density functional theory finds increasingly broad application in the chemical and material sciences for the interpretation and prediction of complex system behavior at an atomic scale.
Bone density, also called bone mass, is the measurement of how many grams of calcium are contained in a portion of bone. The higher the number, the stronger and more dense your bones are. high bone density means that you are less vulnerable to breaking bones as you get older. In the past, doctors would diagnose osteoporosis only after a patient broke one of her bones. Now, doctors can measure your bone density, especially if you are at high risk for osteoporosis.
