  2. Transfer length method - Wikipedia

    en.wikipedia.org/wiki/Transfer_length_method

    The Transfer Length Method or the "Transmission Line Model" (both abbreviated as TLM) is a technique used in semiconductor physics and engineering to determine the specific contact resistivity between a metal and a semiconductor.

  3. Ion transport number - Wikipedia

    en.wikipedia.org/wiki/Ion_transport_number

    The practical importance of high (i.e. close to 1) transference numbers of the charge-shuttling ion (i.e. Li+ in lithium-ion batteries) is related to the fact, that in single-ion devices (such as lithium-ion batteries) electrolytes with the transfer number of the ion near 1, concentration gradients do not develop. A constant electrolyte ...

  4. Marcus theory - Wikipedia

    en.wikipedia.org/wiki/Marcus_theory

    In theoretical chemistry, Marcus theory is a theory originally developed by Rudolph A. Marcus, starting in 1956, to explain the rates of electron transfer reactions – the rate at which an electron can move or jump from one chemical species (called the electron donor) to another (called the electron acceptor). [1]

  5. Charge transfer coefficient - Wikipedia

    en.wikipedia.org/wiki/Charge_transfer_coefficient

    Charge transfer coefficient, and symmetry factor (symbols α and β, respectively) are two related parameters used in description of the kinetics of electrochemical reactions. They appear in the Butler–Volmer equation and related expressions.

  6. Mass transfer coefficient - Wikipedia

    en.wikipedia.org/wiki/Mass_transfer_coefficient

    Quantifying mass transfer allows for design and manufacture of separation process equipment that can meet specified requirements, estimate what will happen in real life situations (chemical spill), etc. Mass transfer coefficients can be estimated from many different theoretical equations, correlations, and analogies that are functions of ...

  7. Fourier number - Wikipedia

    en.wikipedia.org/wiki/Fourier_number

    In the study of heat conduction, the Fourier number, is the ratio of time, , to a characteristic time scale for heat diffusion, .This dimensionless group is named in honor of J.B.J. Fourier, who formulated the modern understanding of heat conduction. [1]

  8. Biot number - Wikipedia

    en.wikipedia.org/wiki/Biot_number

    A temperature distribution chart with Bi on the x-axis. The Biot number (Bi) is a dimensionless quantity used in heat transfer calculations, named for the eighteenth-century French physicist Jean-Baptiste Biot (1774–1862).

  9. Charge-transfer complex - Wikipedia

    en.wikipedia.org/wiki/Charge-transfer_complex

    In chemistry, charge-transfer (CT) complex, or electron donor-acceptor complex, describes a type of supramolecular assembly of two or more molecules or ions. The assembly consists of two molecules that self-attract through electrostatic forces, i.e., one has at least partial negative charge and the partner has partial positive charge, referred ...
