Sir Chandrasekhara Venkata Raman and his student Nagendra Nath published a series of papers in 1936 on the diffraction of light by a liquid in the field of a high frequency sound wave. This was ...

Researchers have developed a holographic data storage approach that stores and retrieves information in three dimensions by ...

Fundamentals of electron diffraction -- Relation between crystal lattice, stereographic projection and reciprocal lattice -- Indexing polycrystalline and single-crystal patterns -- Orientation ...

A pattern of distorted lines is visible as a reflection in this close-up view of a human eye. By observing the deformation of illumination patterns reflected off the eye's surface, researchers in ...

Crystallography is the science of analyzing the pattern produced by shining an X-ray beam through a material sample. A powder sample produces a different pattern than solid crystal. One longstanding ...
