electron diffraction pattern

Electron diffraction patterns suggest that its space group symmetry is P21.

Alternatively, the intermediate can allow an electron diffraction pattern on the viewing screen.

This is the first electron diffraction pattern obtained in the atomic cluster research laboratory.

In 1928, he observed and gave a theoretical explanation of the electron diffraction pattern from a thin mica film.

Measurement of the refraction effect on electron diffraction pattern provides direct estimates of F0.

Electron diffraction patterns showed the expected honeycomb lattice.

Shechtman first observed ten-fold electron diffraction patterns in 1982, as described in his notebook.

To elucidate the structure of the cone walls, electron diffraction patterns were recorded at different cone orientations.

The patterns obtained are also less sensitive to the thickness of the sample, a parameter with strong influence in standard electron diffraction patterns.

This plug-in enables the widely used software package to collect precession electron diffraction patterns without additional modifications to the microscope.

From its electron diffraction pattern, the mineral has been considered to have a carbyne structure, the linear acetylenic carbon allotrope of carbon.

With such a CCD camera one may also collect electron diffraction patterns from 2D crystals with great precision (14 bit dynamic range).

Electron diffraction patterns of samples quenched from 890 C contain bands of highly ordered diffuse scattered radiation, indicative of local short-range ordering.

The electron diffraction patterns of primitive clay precursors show diffuse rings at 2.65, 2.04, and 1.51 Å, suggesting low crystallinity, random orientation, and partial inheritance of the original structure.

In detail, we discuss the grain sizes, phases and structures of the films and alloys as deduced from bright-field and dark-field images and selected area electron diffraction patterns.

In crystallography, the orientations of crystal axes and faces in three-dimensional space are a central geometric concern, for example in the interpretation of X-ray and electron diffraction patterns.

In the case of electron diffraction patterns, structure factor amplitudes can be used, in a later step, to further discern among a selection of candidate structures (so-called 'structure factor fingerprinting').

Precession Electron Diffraction (PED) is a specialized method to collect electron diffraction patterns in a transmission electron microscope (TEM).

The electron diffraction patterns recorded from selected areas of these single crystals were identical and allowed the comparison of our observed basal unit cell parameters with those derived from X-ray fibre diffraction.

Such information is very useful in the analysis of electron diffraction patterns of gases (Chapter 8), and in other experiments where measurements must be conducted upon large collections of molecules in different instantaneous states.

More recently, two slit particle diffraction has been experimentally demonstrated with single-particle buildup of electron diffraction patterns, as may be seen in the photo in this reference and with helium atoms and molecules.

Fourier transforms of HRTEM images and electron diffraction patterns both supply information about the projected reciprocal lattice geometry for a certain crystal orientation, where the projection axis coincides with the optical axis of the microscope.

Theoretical potentials, based on geometry-optimized STO 3G MO computations for 4-fluorobiphenyl and 4,4′-difluorobiphenyl, yield expectation values for the torsion angles about the exocyclic C—C linkage that are very close to those deduced from electron diffraction patterns.

In practice, Kikuchi lines are easily seen in thick regions of either selected area or convergent beam electron diffraction patterns, but difficult to see in diffraction from crystals much less than 100 nm in size (where lattice-fringe visibility effects become important instead).
