Crystal Structure Human Dental Apatite Function of Age
2009/9/2
Studies of the average crystal structure properties of human dental apatite as a function of age in the range of 5–87 years are reported. The crystallinity of the dental hydroxyapatite decreases with ...
Coefficient of crystal lattice matching as a parameter of substrate - crystal structure compatibility in silumins
Theoretical fundamentals of the crystallisation process Lattice parameter Nucleation Silumins
2011/4/1
Adding high-melting point elements (Mo, Nb, Ni, Ti, W) to complex silumins results in hardening of the latter ones, owing to the formation of new intermetallic phases of the AlxMey type, with refinem...
