Swift electron energy losses have been investigated in nanoporous alumina, taking into account retardation effects. A simple analytical expression is obtained for the energy loss probability. The electron energy loss spectra observed with the Scanning transmission electron microscope are reasonably well reproduced using a simple model consisting of a cylindrical shell of alumina surrounded by an effective...
This research will contribute to the interpretation of magnetic flux leakage data as well as collecting fundamental data on the stress and magnetic properties of steel piping materials. This is important to the increasingly important technology of non-destructive evaluation of natural gas transmission piping.
