  2. Clark electrode - Wikipedia

    en.wikipedia.org/wiki/Clark_electrode

    The Clark electrode [1] [2] is an electrode that measures ambient oxygen partial pressure in a liquid using a catalytic platinum surface according to the net reaction: [3] O 2 + 4 e − + 4 H + → 2 H 2 O. It improves on a bare platinum electrode by use of a membrane to reduce fouling and metal plating onto the platinum. [4]

  3. Hyperoxia - Wikipedia

    en.wikipedia.org/wiki/Hyperoxia

    Hyperoxia is the state of being exposed to high levels of oxygen; it may refer to organisms, cells and tissues that are experiencing excessive oxygenation, [1] or to an abnormally high oxygen concentration in an environment (e.g. a body of water).

  4. Indirect calorimetry - Wikipedia

    en.wikipedia.org/wiki/Indirect_calorimetry

    Indirect calorimetry measures O 2 and nitrogen consumption and CO 2 production. On the assumption that all the oxygen is used to oxidize degradable fuels and all the CO 2 thereby evolved is recovered, it is possible to estimate the total amount of energy produced from the chemical energy of nutrients and converted into the chemical energy of ...

  5. Energy flow (ecology) - Wikipedia

    en.wikipedia.org/wiki/Energy_flow_(ecology)

    There are two major food chains: The primary food chain is the energy coming from autotrophs and passed on to the consumers; and the second major food chain is when carnivores eat the herbivores or decomposers that consume the autotrophic energy. [16] Consumers are broken down into primary consumers, secondary consumers and tertiary consumers.

    Foods is a peer-reviewed scientific journal covering various aspects of food science.It is published by MDPI and was established in 2012. The editor-in-chief is Arun K. Bhunia (Purdue University).

  7. Food physical chemistry - Wikipedia

    en.wikipedia.org/wiki/Food_physical_chemistry

    Food physical chemistry is essential for improving the quality of foods, their stability, and food product development. Because food science is a multi-disciplinary field, food physical chemistry is being developed through interactions with other areas of food chemistry and food science, such as food analytical chemistry, food process ...

  8. Isotope analysis - Wikipedia

    en.wikipedia.org/wiki/Isotope_analysis

    Archaeological materials, such as bone, organic residues, hair, or sea shells, can serve as substrates for isotopic analysis. Carbon, nitrogen and zinc isotope ratios are used to investigate the diets of past people; these isotopic systems can be used with others, such as strontium or oxygen, to answer questions about population movements and cultural interactions, such as trade.
