  2. Chemical vapor infiltration - Wikipedia

    en.wikipedia.org/wiki/Chemical_vapor_infiltration

    A typical demonstration of the process is shown in Figure 1. Here, the gases and matrix material enter the reactor from the feed system at the bottom of the reactor. The fibrous preform undergoes a chemical reaction at high temperature with the matrix material and thus the latter infiltrates in the fiber or preform crevices.

  3. Cinerama - Wikipedia

    en.wikipedia.org/wiki/Cinerama

    Cinerama is a widescreen process that originally projected images simultaneously from three synchronized 35mm projectors onto a huge, deeply curved screen, subtending 146-degrees of arc. [2] [3] The trademarked process was marketed by the Cinerama corporation. It was the first of several novel processes introduced during the 1950s when the ...

  4. Abiological nitrogen fixation using homogeneous catalysts

    en.wikipedia.org/wiki/Abiological_nitrogen...

    The dominant technology for abiological nitrogen fixation is the Haber process, which uses iron-based heterogeneous catalysts and H 2 to convert N 2 to NH 3. This article focuses on homogeneous (soluble) catalysts for the same or similar conversions.

  5. Atomic layer deposition - Wikipedia

    en.wikipedia.org/wiki/Atomic_layer_deposition

    By alternating exposures of A and B, a thin film is deposited. This process is shown in the side figure. Consequently, when describing an ALD process one refers to both dose times (the time a surface is being exposed to a precursor) and purge times (the time left in between doses for the precursor to evacuate the chamber) for each precursor.

  6. Photographic processing - Wikipedia

    en.wikipedia.org/wiki/Photographic_processing

    In the RA-4 process, the bleach and fix are combined. This is optional, and reduces the number of processing steps. [12] Transparency films, except Kodachrome, are developed using the E-6 process, which has the following stages: A black and white developer develops the silver in each image layer. Development is stopped with a rinse or a stop bath.

  7. DNA-encoded chemical library - Wikipedia

    en.wikipedia.org/wiki/DNA-encoded_chemical_library

    The center of 3, 4 and 5 way DNA junctions (a 4-way junction is shown here) becomes a yoctoliter-scale reactor where small molecule synthesis is facilitated in what has been termed the YoctoReactor (yR). Colored circles depict the chemical building blocks (BB) which are attached to carefully designed DNA oligonucleotides (black lines).

  8. Hydrodesulfurization - Wikipedia

    en.wikipedia.org/wiki/Hydrodesulfurization

    Hydrodesulfurization or hydrodesulphurisation (Commonwealth English; see spelling differences) (HDS), also called hydrotreatment or hydrotreating, is a catalytic chemical process widely used to remove sulfur (S) from natural gas and from refined petroleum products, such as gasoline or petrol, jet fuel, kerosene, diesel fuel, and fuel oils.

  9. Condyloid process - Wikipedia

    en.wikipedia.org/wiki/Condyloid_process

    The condyloid process or condylar process is the process on the human and other mammalian species' mandibles that ends in a condyle, the mandibular condyle.It is thicker than the coronoid process of the mandible and consists of two portions: the condyle and the constricted portion which supports it, the neck.
