Quasicrystals are intriguing materials with long-range atomic order that lack periodicity. It has been a longstanding ...

A pattern of distorted lines is visible as a reflection in this close-up view of a human eye. By observing the deformation of ...

It involves the interaction of a beam of electrons with a crystalline sample, resulting in a diffraction pattern that provides information about the arrangement of atoms within the material. This ...

Captured here is a laser diffraction pattern, visible as a series of concentric circles with a bright central area. This pattern is a result of light waves spreading out and overlapping after passing ...

Description: Electron diffraction patterns for single crystal and polycrystalline materials are displayed on a CRT screen. A Welch model 2639 'Electron Diffraction tube' is used in an experiment in ...

When a laser beam is incident on a narrow opaque object such as a fine wire or a strand of hair, the resulting diffraction pattern is similar to the diffraction pattern of a slit of the same width as ...

These patterns serve as an illumination source ... which is beyond the diffraction limit. The device also supports optical surface imaging by generating evanescent speckles when the incident ...
