  Quantitatively reliable atomic pair distribution functions (PDFs) have been
obtained from nanomaterials in a straightforward way from a standard laboratory
transmission electron microscope (TEM). The approach looks very promising for
making electron-derived PDFs (ePDFs) a routine step in the characterization of
nanomaterials because of the ubiquity of such TEMs in chemistry and materials
laboratories. No special attachments such as energy filters were required on
the microscope. The methodology for obtaining the ePDFs is described as well as
some opportunities and limitations of the method.
