What is ray crystallography?

Some articles on ray crystallography, ray, rays, crystallography:

Electron Crystallography - Comparison With X-ray Crystallography
... It can complement X-ray crystallography for studies of very small crystals ( 1 micrometer) crystals impervious to electrons, which only penetrate short distances ... One of the main difficulties in X-ray crystallography is determining phases in the diffraction pattern ... Because no X-ray lens exists, X-rays cannot be used to form an image of the crystal being diffracted, and hence phase information is lost ...
Timeline Of Chemistry - 20th Century
... Bragg's law and establish the field of X-ray crystallography, an important tool for elucidating the crystal structure of substances ... which are key principles for the use of X-ray crystallography to deduce molecular structure. 1951 Linus Pauling uses X-ray crystallography to deduce the secondary structure of proteins ...
X-ray Crystallography - Methods - Overview of Single-crystal X-ray Diffraction - Limitations
... and more complex, the atomic-level picture provided by X-ray crystallography becomes less well-resolved (more "fuzzy") for a given number of observed reflections ... Two limiting cases of X-ray crystallography—"small-molecule" and "macromolecular" crystallography—are often discerned ... Small-molecule crystallography typically involves crystals with fewer than 100 atoms in their asymmetric unit such crystal structures are usually so ...
Dorothy Hodgkin
... chemist, credited with the development of protein crystallography ... She advanced the technique of X-ray crystallography, a method used to determine the three dimensional structures of biomolecules ... X-ray crystallography became a widely used tool and was critical in later determining the structures of many biological molecules where knowledge of structure is critical to an ...

Famous quotes containing the word ray:

    These facts have always suggested to man the sublime creed that the world is not the product of manifold power, but of one will, of one mind; and that one mind is everywhere active, in each ray of the star, in each wavelet of the pool; and whatever opposes that will is everywhere balked and baffled, because things are made so, and not otherwise.
    Ralph Waldo Emerson (1803–1882)
