XRD Analysis of Crystal Structure of the Fragment of the Campo Del Cielo Meteorite

Meteorites are the key, and often the only source of information about the pre-planetary and planetary early history of our solar system. Currently, the following classification of meteorites: stone (aerolites) stoney-iron (siderolites) and iron (siderites), depending on the ratio of silicate minerals in them, and nickel-iron

Surface magnetism of non-ideal iron borate single crystal

Considered is the influence of crystalline structure imperfections in near-surface layer of easy-plane weak ferromagnet iron borate, FeB0₃, on the effects of surface magnetism observed therein. It is shown that the surface reconstruction and point defects therein change the surface magnetic properties of the crystal very considerably.Розглянуто вплив недосконалості кристалічної структури приповерхневого шару легкоплощинного слабкого феромагнетика борату заліза FeB0₃ на ефекти поверхневого магнетизму, що спостерігається у ньому. Показано, що реконструкція поверхні і наявність в ній точкових дефектів значно змінюють поверхневі магнітні властивості цього кристала.Рассмотрено влияние несовершенств кристаллической структуры приповерхностного слоя легкоплоскостного слабого ферромагнетика бората железа, FeB0₃, на эффекты наблюдаемого в нем поверхностного магнетизма. Показано, что реконструкция поверхности и наличие в ней точечных дефектов весьма значительно изменяют поверхностные магнитные свойства этого кристалла

Crystal phase in composition of mandible regenerate on a background the lead poisoning and conducted antitoxic correction

Results of the radiostructure research of reparative osteogenesis of the mandible on a background the lead poisoning and conducted antitoxic correction are presented in the article. It’s determined that the base crystal phase of the mandible regenerate are presented by hydroxyapatite with special diffracted reflexes. The parameters of elementary crystal cell in hy-droxyapatite are less then the same parameters in mother bone. During the correction processes with remedy Mg B6, it possi-ble to notice the entry of Mg B6 to the new crystal lattice.During the lead poisoning, parameters of the hydroxyapatite lattice are increased, so the lead’s entry to the lattice is possible. MgB6 can stop this process. The remedy Tetacinum Ca together with MgB6 can decrease the impression of the crystal phase
