  2. Disk diffusion test - Wikipedia

    en.wikipedia.org/wiki/Disk_diffusion_test

    The disk diffusion test (also known as the agar diffusion test, Kirby–Bauer test, disc-diffusion antibiotic susceptibility test, disc-diffusion antibiotic sensitivity test and KB test) is a culture-based microbiology assay used in diagnostic and drug discovery laboratories. In diagnostic labs, the assay is used to determine the susceptibility ...

  3. Forced Rayleigh scattering - Wikipedia

    en.wikipedia.org/wiki/Forced_Rayleigh_scattering

    FRS studies of molecular mass diffusion are somewhat more involved than studies of thermal diffusion or thermophoresis because the ground and excited dye states may have different diffusion coefficients. [6] [7] When this is the case, two gratings differing in phase by 180 degrees are present: the excited state grating and a complementary ...

  5. Rayleigh–Bénard convection - Wikipedia

    en.wikipedia.org/wiki/Rayleigh–Bénard_convection

    [6] [7] Buoyancy, and hence gravity, are responsible for the appearance of convection cells. The initial movement is the upwelling of less-dense fluid from the warmer bottom layer. [8] This upwelling spontaneously organizes into a regular pattern of cells. Rayleigh–Bénard convection produces complex patterns of frost damage in grass. [9]

  6. Diffusion-controlled reaction - Wikipedia

    en.wikipedia.org/wiki/Diffusion-controlled_reaction

    Diffusion-controlled (or diffusion-limited) reactions are reactions in which the reaction rate is equal to the rate of transport of the reactants through the reaction medium (usually a solution). [1] The process of chemical reaction can be considered as involving the diffusion of reactants until they encounter each other in the right ...

  9. Fick's laws of diffusion - Wikipedia

    en.wikipedia.org/wiki/Fick's_laws_of_diffusion

    Fick's first law relates the diffusive flux to the gradient of the concentration. It postulates that the flux goes from regions of high concentration to regions of low concentration, with a magnitude that is proportional to the concentration gradient (spatial derivative), or in simplistic terms the concept that a solute will move from a region of high concentration to a region of low ...
