Significats de electron diffraction en anglès

Using transmission electron microscopy and electron diffraction analysis, long and parallel-oriented hydroxyapatite crystals were observed in lungfish outer tooth coverings.

Cytochemical analysis, X-ray spectrometry, and electron diffraction showed that these aggregates corresponded to crystals of calcium phosphate in an apatite-like structure.

The polarization dependences of the phonon modes are compared with transmission electron diffraction measurements to determine the crystallographic orientation of the samples.

The annealing behavior of amorphous i-PMMA thin films on highly oriented HDPE substrates was studied by transmission infrared spectroscopy and electron diffraction.

In the 33-day cultures, several masses of calcified matrix were formed and it was confirmed to be apatite by selected-area electron diffraction analysis.

Here we studied the crystal structure of SmFe 2 by high-resolution synchrotron X-ray powder diffraction, X-ray total scattering, and selected-area electron diffraction methods.

Micrometric fibres with anisotropic alignment of DPP dye were produced by this process as shown by polarized optical microscopy and selected area electron diffraction.

The 0.62 Å resolution structure is assumed to be closely related to the fibrillar form of phenylalanine, as observed by electron microscopy and electron diffraction.

The single crystal surface, processed by ultrahigh vacuum cleaning and oxygen annealing, shows a (1 × 1) periodicity in the low-energy electron diffraction pattern.

Electron diffraction can provide reliable amplitudes, which can be combined with the phases from the images.

Electron diffraction confirmed the presence of large HA crystals that produced a diffraction pattern indicative of a rod-like crystal structure.

Electron diffraction analysis further demonstrated that the contact planes of this epitaxial system are (100) lattice planes of both polymers.
