  2. Zeta potential - Wikipedia

    en.wikipedia.org/wiki/Zeta_potential

    In other words, zeta potential is the potential difference between the dispersion medium and the stationary layer of fluid attached to the dispersed particle. The zeta potential is caused by the net electrical charge contained within the region bounded by the slipping plane, and also depends on the location of that plane. Thus, it is widely ...

  3. Zeta potential titration - Wikipedia

    en.wikipedia.org/wiki/Zeta_potential_titration

    Zeta potential titration is a titration of heterogeneous systems, for example colloids and emulsions. Solids in such systems have very high surface area. This type of titration is used to study the zeta potential of these surfaces under different conditions. Details of zeta potential definition and measuring techniques can be found in the ...

  4. Titration - Wikipedia

    en.wikipedia.org/wiki/Titration

    (This is an example of an ion-selective electrode.) The pH of the solution is measured throughout the titration, more accurately than with an indicator; at the endpoint there will be a sudden change in the measured pH. Conductivity: A measurement of ions in a solution. Ion concentration can change significantly in a titration, which changes the ...

  5. Excitation-transfer theory - Wikipedia

    en.wikipedia.org/wiki/Excitation-transfer_theory

    Example - Watching a movie within the genre of thriller, suspense or horror. Explanation - The initial stimulus would be the act or situation of watching a movie within one of these genres. Physical responses including an increased heart rate and elevated levels of adrenaline would be the physiological arousal components of the theory.

  6. Coombs test - Wikipedia

    en.wikipedia.org/wiki/Coombs_test

    RBCs have a net negative charge called zeta potential which causes them to have a natural repulsion for one another. Potentiators reduce the zeta potential of RBC membranes. Common potentiators include low ionic strength solution (LISS), albumin , polyethylene glycol (PEG), and proteolytic enzymes .

  7. Sedimentation potential - Wikipedia

    en.wikipedia.org/wiki/Sedimentation_potential

    Smoluchowski's sedimentation potential is defined where ε 0 is the permitivity of free space, D the dimensionless dielectric constant, ξ the zeta potential, g the acceleration due to gravity, Φ the particle volume fraction, ρ the particle density, ρ o the medium density, λ the specific volume conductivity, and η the viscosity. [8]

  8. Electro-osmosis - Wikipedia

    en.wikipedia.org/wiki/Electro-osmosis

    where U is the velocity vector, ρ is the density of the fluid, / is the material derivative, μ is the viscosity of the fluid, ρ e is the electric charge density, ϕ is the applied electric field, ψ is the electric field due to the zeta potential at the walls and p is the fluid pressure.

  9. Riemann zeta function - Wikipedia

    en.wikipedia.org/wiki/Riemann_zeta_function

    The Riemann zeta function ζ(z) plotted with domain coloring. [1] The pole at = and two zeros on the critical line.. The Riemann zeta function or Euler–Riemann zeta function, denoted by the Greek letter ζ (), is a mathematical function of a complex variable defined as () = = = + + + for ⁡ >, and its analytic continuation elsewhere.
