  2. Methylphosphonyl dichloride - Wikipedia

    en.wikipedia.org/wiki/Methylphosphonyl_dichloride

    Methylphosphonyl dichloride (DC) or dichloro is an organophosphorus compound. It has commercial application in oligonucleotide synthesis, [ 1 ] but is most notable as being a precursor to several chemical weapons agents.

  3. Solution-friction model - Wikipedia

    en.wikipedia.org/wiki/Solution-friction_model

    The SF model has been able to successfully describe the transport of water and salt in RO membranes, showing good agreement with experiments. [ 1 ] [ 4 ] [ 5 ] [ 6 ] The development of the SF model also corrects the misconception that RO water transport is a diffusion -based process.

  4. Methyldichlorophosphine - Wikipedia

    en.wikipedia.org/wiki/Methyldichlorophosphine

    Methyldichlorophosphine belongs to the group of halophosphines, some of which are used as intermediates in the production of plant protection agents, stabilizers for plastics, and catalysts.

  5. Membrane transport - Wikipedia

    en.wikipedia.org/wiki/Membrane_transport

    In cellular biology, membrane transport refers to the collection of mechanisms that regulate the passage of solutes such as ions and small molecules through biological membranes, which are lipid bilayers that contain proteins embedded in them. The regulation of passage through the membrane is due to selective membrane permeability – a ...

  6. Membrane transport protein - Wikipedia

    en.wikipedia.org/wiki/Membrane_transport_protein

    A membrane transport protein is a membrane protein involved in the movement of ions, small molecules, and macromolecules, such as another protein, across a biological membrane. Transport proteins are integral transmembrane proteins; that is they exist

  7. Monte Carlo method for photon transport - Wikipedia

    en.wikipedia.org/wiki/Monte_Carlo_method_for...

    Modeling photon propagation with Monte Carlo methods is a flexible yet rigorous approach to simulate photon transport. In the method, local rules of photon transport are expressed as probability distributions which describe the step size of photon movement between sites of photon-matter interaction and the angles of deflection in a photon's trajectory when a scattering event occurs.

  8. Dimethyl methylphosphonate - Wikipedia

    en.wikipedia.org/wiki/Dimethyl_methylphosphonate

    It will react with thionyl chloride to produce methylphosphonic acid dichloride, which is used in the production of sarin and soman nerve agents. Various amines can be used to catalyse this process. [3] It can be used as a sarin-simulant for the calibration of organophosphorus detectors.

  9. Pressure flow hypothesis - Wikipedia

    en.wikipedia.org/wiki/Pressure_Flow_Hypothesis

    Some plants appear not to load phloem by active transport. In these cases, a mechanism known as the polymer trap mechanism was proposed by Robert Turgeon . [ 5 ] In this model, small sugars such as sucrose move into intermediary cells through narrow plasmodesmata, where they are polymerised to raffinose and other larger oligosaccharides .
