Cao, F.; Beyerlein, I. J.; Addessio, F. L.; Sencer, B. H.; Trujillo, C. P.; Cerreta, E. K.; Gray III, G. T.

Shock recovery experiments have been conducted to assess the role of shock stress and orientation dependence on substructure evolution and deformation twinning of a [1 0 0]/ copper bicrystal.
Measuring the thickness of aluminium alloy thin foils using electron energy loss spectroscopy

Publication

Materials Characterization

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.
D-STEM: A parallel electron diffraction technique applied to nanomaterials

Publication

Microscopy and Microanalysis

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.
Four-dimensional electron microscopy

Publication

Science

Zewail, A. H.

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.
Electron microscopy of pharmaceutical systems

TEM studies of nanostructure in melt-spun Mg-Ni-La alloy manifesting enhanced hydrogen desorbing kinetics

Publication

Journal of Alloys and Compounds

Tanaka, K.; Miwa, T.; Sasaki, K.; Kuroda, K.

The hydrogen storage properties of a magnesium-rich Mg–Ni–La alloy prepared by melt-spinning are significantly improved by nanostructure formation during crystallization and activation. It can absorb and desorb ∼5 wt% hydrogen at temperatures as low as 200 °C in moderate time periods.
