  2. Growth medium - Wikipedia

    en.wikipedia.org/wiki/Growth_medium

    A growth medium or culture medium is a solid, liquid, or semi-solid designed to support the growth of a population of microorganisms or cells via the process of cell proliferation [1] or small plants like the moss Physcomitrella patens. [2] Different types of media are used for growing different types of cells. [3]

  3. Quasi-solid - Wikipedia

    en.wikipedia.org/wiki/Quasi-solid

    Quasi-solid. Quasi-solid, Falsely-solid, or semisolid is the physical term for something whose state lies between a solid and a liquid. While similar to solids in some respects, such as having the ability to support their own weight and hold their shapes, a quasi-solid also shares some properties of liquids, such as conforming in shape to ...

  4. Tissue culture - Wikipedia

    en.wikipedia.org/wiki/Tissue_culture

    Tissue culture is the growth of tissues or cells in an artificial medium separate from the parent organism. This technique is also called micropropagation. This is typically facilitated via use of a liquid, semi-solid, or solid growth medium, such as broth or agar. Tissue culture commonly refers to the culture of animal cells and tissues, with ...

  5. Cell culture - Wikipedia

    en.wikipedia.org/wiki/Cell_culture

    This is typically facilitated via use of a liquid, semi-solid, or solid growth medium, such as broth or agar. Tissue culture commonly refers to the culture of animal cells and tissues, with the more specific term plant tissue culture being used for plants. The lifespan of most cells is genetically determined, but some cell-culturing cells have ...

  6. Solid-state electronics - Wikipedia

    en.wikipedia.org/wiki/Solid-state_electronics

    The term is also used as an adjective for devices in which semiconductor electronics that have no moving parts replace devices with moving parts, such as the solid-state relay in which transistor switches are used in place of a moving-arm electromechanical relay, or the solid-state drive (SSD) a type of semiconductor memory used in computers to ...

  7. Solid-state laser - Wikipedia

    en.wikipedia.org/wiki/Solid-state_laser

    Solid-state laser. A solid-state laser is a laser that uses a gain medium that is a solid, rather than a liquid as in dye lasers or a gas as in gas lasers. [1] Semiconductor -based lasers are also in the solid state, but are generally considered as a separate class from solid-state lasers, called laser diodes .

  8. Solid-state drive - Wikipedia

    en.wikipedia.org/wiki/Solid-state_drive

    A solid-state drive ( SSD) is a solid-state storage device. It provides persistent data storage using no moving parts. It is sometimes called semiconductor storage device or solid-state device; it is also called solid-state disk because it is frequently interfaced to a host system as a hard disk drive. [1] [2]

  9. Porous medium - Wikipedia

    en.wikipedia.org/wiki/Porous_medium

    Open-cell ceramic. In materials science, a porous medium or a porous material is a material containing pores (voids). [1] The skeletal portion of the material is often called the "matrix" or "frame". The pores are typically filled with a fluid ( liquid or gas ). The skeletal material is usually a solid, but structures like foams are often also ...
