Tóm tắt:Title screen
The paper presents the results of experimental research on the annihilation of positrons in hydrogen storage materials based on magnesium and single-wall carbon nanotubes during thermal annealing. It is shown that the characteristics of positron annihilation in such materials are related to their microstructural changes. In a composite based on magnesium hydride and carbon nanotubes, the rate of hydrogen release during dehydrogenation reveals three peaks due to the specific morphology of carbon nanotubes included in the magnesium matrix. During dehydrogenation, the composite undergoes irreversible changes in its electronic and/or defect structure.
