    The discovery of the electron over a century ago and the realization of its dual character have given birth to one of the two most powerful imaging instruments: the electron microscope.

    Ganesh, K. J.; Kawasaki, M.; Zhou, J. P.; Ferreira, P. J.

    An electron diffraction technique called D-STEM has been developed in a transmission electron microscopy/scanning transmission electron microscopy (TEM/STEM) instrument to obtain spot electron diffraction patterns from nanostructures, as small as ∼3 nm.

    Bardal, A.; Lie, K.

    Combining electron energy loss spectroscopy and convergent beam electron diffraction measurements, we have determined the mean-free-path for inelastic electron scattering for four different aluminium alloys.

    Pd/Au alloys have attracted a lot of interest due to their resistance at high temperatures, and this explains their use in several fields, such as CO and hydrocarbon oxidation, synthesis of vinyl acetate monomer, hydrocarbon hydrogenation, and many others.
