  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. Protein crystallization - Wikipedia

    en.wikipedia.org/wiki/Protein_crystallization

    Developing protein crystals is a difficult process influenced by many factors, including pH, temperature, ionic strength in the crystallization solution, and even gravity. [3] Once formed, these crystals can be used in structural biology to study the molecular structure of the protein, particularly for various industrial or medical purposes. [4 ...

  4. Crystallography - Wikipedia

    en.wikipedia.org/wiki/Crystallography

    In addition, physical properties are often controlled by crystalline defects. The understanding of crystal structures is an important prerequisite for understanding crystallographic defects. Most materials do not occur as a single crystal, but are poly-crystalline in nature (they exist as an aggregate of small crystals with different orientations).

  5. Biocrystallization - Wikipedia

    en.wikipedia.org/wiki/Biocrystallization

    Biocrystallization is the formation of crystals from organic macromolecules by living organisms. [1] This may be a stress response, a normal part of metabolism such as processes that dispose of waste compounds, or a pathology. Template mediated crystallization is qualitatively different from in vitro crystallization.

  6. Virus crystallisation - Wikipedia

    en.wikipedia.org/wiki/Virus_Crystallisation

    Virus crystallisation is the re-arrangement of viral components into solid crystal particles. [1] The crystals are composed of thousands of inactive forms of a particular virus arranged in the shape of a prism. [2] The inactive nature of virus crystals provide advantages for immunologists to effectively analyze the structure and function behind ...

  7. Crystal - Wikipedia

    en.wikipedia.org/wiki/Crystal

    A crystal's crystallographic forms are sets of possible faces of the crystal that are related by one of the symmetries of the crystal. For example, crystals of galena often take the shape of cubes, and the six faces of the cube belong to a crystallographic form that displays one of the symmetries of the isometric crystal system. Galena also ...

  8. Self-assembly - Wikipedia

    en.wikipedia.org/wiki/Self-assembly

    Examples of self-assembly at gas-liquid interfaces include breath-figures, self-assembled monolayers, droplet clusters, and Langmuir–Blodgett films, while crystallization of fullerene whiskers is an example of macroscopic self-assembly in between two liquids.

  9. Crystal structure - Wikipedia

    en.wikipedia.org/wiki/Crystal_structure

    All crystals have translational symmetry in three directions, but some have other symmetry elements as well. For example, rotating the crystal 180° about a certain axis may result in an atomic configuration that is identical to the original configuration; the crystal has twofold rotational symmetry about this axis.
