  2. Crystallization - Wikipedia

    en.wikipedia.org/wiki/Crystallization

    Crystallization is the process by which solids form, where the atoms or molecules are highly organized into a structure known as a crystal. Some ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.

  3. List of purification methods in chemistry - Wikipedia

    en.wikipedia.org/wiki/List_of_purification...

    The pure solid crystals are then separated from the remaining liquor by filtration or centrifugation. Recrystallization : In analytical and synthetic chemistry work, purchased reagents of doubtful purity may be recrystallised, e.g. dissolved in a very pure solvent, and then crystallized, and the crystals recovered, in order to improve and/or ...

  4. Crystallography - Wikipedia

    en.wikipedia.org/wiki/Crystallography

    Crystallography ranges from the fundamentals of crystal structure to the mathematics of crystal geometry, including those that are not periodic or quasicrystals. At the atomic scale it can involve the use of X-ray diffraction to produce experimental data that the tools of X-ray crystallography can convert into detailed positions of atoms, and ...

  5. Crystal chemistry - Wikipedia

    en.wikipedia.org/wiki/Crystal_Chemistry

    Fundamentals of crystallography: crystal systems, Miller Indices, symmetry elements, bond lengths and radii, theoretical density; Crystal and glass structure prediction: Pauling's and Zachariasen’s rules; Phase diagrams and crystal chemistry (including solid solutions) Imperfections (including defect chemistry and line defects) Phase transitions

  6. X-ray crystallography - Wikipedia

    en.wikipedia.org/wiki/X-ray_crystallography

    X-ray crystallography is still the primary method for characterizing the atomic structure of materials and in differentiating materials that appear similar in other experiments. X-ray crystal structures can also help explain unusual electronic or elastic properties of a material, shed light on chemical interactions and processes, or serve as ...

  7. Protein crystallization - Wikipedia

    en.wikipedia.org/wiki/Protein_crystallization

    Protein crystallization is the process of formation of a regular array of individual protein molecules stabilized by crystal contacts. If the crystal is sufficiently ordered, it will diffract . Some proteins naturally form crystalline arrays, like aquaporin in the lens of the eye.

  8. Crystallization adjutant - Wikipedia

    en.wikipedia.org/wiki/Crystallization_adjutant

    A crystallization adjutant is a material used to promote crystallization, normally in a context where a material does not crystallize naturally from a pure solution. Additives in Macromolecular Crystallization

  9. Bridgman–Stockbarger method - Wikipedia

    en.wikipedia.org/wiki/Bridgman–Stockbarger_method

    The Bridgman method is a popular way of producing certain semiconductor crystals such as gallium arsenide, for which the Czochralski method is more difficult. The process can reliably produce single-crystal ingots, but does not necessarily result in uniform properties through the crystal. [1]
