The possibility of such bioartifical tissues has been fueled by major advances in cell and molecular biology and the development of more sophisticated cell-culture technologies.

I must stop here now but I shall come back to you later.Editors Univ.-Prof. Why? Because the amorphous form of silicates also contain the Si-O tetrahedra like the crystalline variety. For example in silicates you will find Si-O distances are almost identical in glassy (amorphous) and crystalline forms.
The first neighbor distances are almost idential in many cases. These near-neighbor distances are are often very similar to that known in crystalline analogue of the amorphous sample.
But if you analyze this intensity distribution carefully by doing inverse Fourier transformation then the resulting pair distribution function in the real space will give you distances of atoms from a central atoms and their their number. If you look at the X-ray 9or neutron) diffraction pattern from amorphous carefully you will find that intensity varies with the scattering angle and form very broad peaks. But amorphous substances are not really collection of atoms with random distribution. So the diffraction from them do not show sharp Bragg peaks. The amorphous substances do not possess this long range order. The crystalline substances have long range order. The diffraction from ideal crystalline substances are characterized by well defined Bragg peaks in X-ray diffraction.
