Scanning Transmission Electron Microscopy for Nanostructure Characterization

Quantitative characterization of electron detectors for transmission electron microscopy.

A new generation of direct electron detectors for transmission electron microscopy (TEM) promises significant improvement over previous detectors in terms of their modulation transfer function (MTF) and detective quantum efficiency (DQE). However, the performance of these new detectors needs to be carefully monitored in order to optimize imaging conditions and check for degradation over time. W...

Transmission Electron Microscopy (TEM) Characterization of doped α-Alumina

Qualitative EDX analysis: A map is acquired in low magnification. Results show equiaxial grains finely distributed through out the sample. In spite of the fact that simulations indicate no clear energetic gain or loss for cosegreation over single dopant segregation in this material, we observed that in all grain boundaries these two dopants (Y an La) are segregating together (figure 2). This co...

Visualization and characterization of receptor clusters by transmission electron microscopy.

Multivalency is a feature common to many natural glycoconjugates, including glucosaminoglycans, mucins, and lipopolysaccharides. Multivalent ligands often bind avidly to their target receptors. In addition, they can simultaneously bind multiple receptors and cause them to become clustered (Fig. 1). Receptor clustering by multivalent ligands modulates the cell adhesion and signaling functions of...
