Understanding the role of dislocations in the mechanical properties of materials represented a great advance. Today, nondestructive materials testing has developed into an important field.

,Electric Conductor or Insulator?—Energy Bands,Application of quantum mechanics to the electrons in the periodic potential of the crystal lattice yields the energy bands separated from each other by forbidden energy gaps. Depending on how the energy states are occupied by electrons, we deal with electrical conductors, semiconductors, or insulators.

Transatlantic Science and Technologylection at a mirror plane, and inversion at a point result in the 32 crystallographic point groups. The diffraction of X-rays by a crystal, initiated in 1912 by Max von Laue, represented the first experimental proof of the regular lattice structure of a crystal. The elements of diffraction theory, i
