    Carbonless copy paper; Photographic processes: Reflex copying process (also reflectography, reflexion copying) Breyertype, Playertype, Manul Process, Typon Process, Dexigraph, Linagraph; Daguerreotype; Salt print; Calotype (the first photo process to use a negative, from which multiple prints could be made) Cyanotype; Photostat machine; Rectigraph

  3. Biological carbon fixation - Wikipedia

    en.wikipedia.org/wiki/Biological_carbon_fixation

    Biological carbon fixation, or сarbon assimilation, is the process by which living organisms convert inorganic carbon (particularly carbon dioxide, CO 2) to organic compounds. These organic compounds are then used to store energy and as structures for other biomolecules .

  4. Mimeograph - Wikipedia

    en.wikipedia.org/wiki/Mimeograph

    The process was called mimeography, and a copy made by the process was a mimeograph. Mimeographs, along with spirit duplicators and hectographs, were common technologies for printing small quantities of a document, as in office work, classroom materials, and church bulletins.

  5. Dissolved organic carbon - Wikipedia

    en.wikipedia.org/wiki/Dissolved_organic_carbon

    Recalcitrant dissolved organic carbon is evenly spread throughout the water column and consists of high molecular weight and structurally complex compounds that are difficult for marine organisms to use such as the lignin, pollen, or humic acids. As a result, the observed vertical distribution consists of high concentrations of labile DOC in ...

  6. Biogeochemical cycle - Wikipedia

    en.wikipedia.org/wiki/Biogeochemical_cycle

    The terrestrial subsurface is the largest reservoir of carbon on earth, containing 14–135 Pg of carbon [36] and 2–19% of all biomass. [37] Microorganisms drive organic and inorganic compound transformations in this environment and thereby control biogeochemical cycles.

  7. Direct air capture - Wikipedia

    en.wikipedia.org/wiki/Direct_air_capture

    Flow diagram of direct air capture process using sodium hydroxide as the absorbent and including solvent regeneration An example of what Direct Air Capture could look like and how the process works. Direct air capture ( DAC ) is the use of chemical or physical processes to extract carbon dioxide (CO 2 ) directly from the ambient air. [ 1 ]

  8. Remineralisation - Wikipedia

    en.wikipedia.org/wiki/Remineralisation

    Remineralisation is normally viewed as it relates to the cycling of the major biologically important elements such as carbon, nitrogen and phosphorus. While crucial to all ecosystems, the process receives special consideration in aquatic settings, where it forms a significant link in the biogeochemical dynamics and cycling of aquatic ecosystems.

  9. Carbon copy - Wikipedia

    en.wikipedia.org/wiki/Carbon_copy

    A copy made with carbon paper. Before the development of photographic copiers, a carbon copy was the under-copy of a typed or written document placed over carbon paper and the under-copy sheet itself (not to be confused with the carbon print family of photographic reproduction processes). [1]
