The crystalline solids |
Crystalline structure. Microscopic appearances. Crystalline morphology: macroscopic appearances. |
Three-dimensional networks |
Space groups. Indexes of Miller. Fractional coordinates and axes of zone. |
Technicians of diffraction |
Methods of *monocristal and of dust. Spectrums of diffraction of X-rays: Law of *Bragg. Sphere of *Ewald. Factor of structure. The problem of the phase. |
Some applications of the technicians of diffraction |
Characterisation of ceramic materials and alloys. Determination of the structure of proteins. Analysis *textural of amorphous materials and biological samples. Follow-up in real time of transitions of phase. |
Geochronology |
Radioactive isotopes. Nuclear stability. Mechanisms of decomposition. Half life. Systems of temporary dating: *K-*Ar, *Rb-*Sr, *Sm-*Nd, Or-*Th-*Pb, 14C. Other methods of dating: footprints of fission. |
