  2. Langmuir (unit) - Wikipedia

    en.wikipedia.org/wiki/Langmuir_(unit)

    The langmuir (symbol: L) is a unit of exposure (or dosage) to a surface (e.g. of a crystal) and is used in ultra-high vacuum (UHV) surface physics to study the adsorption of gases. It is a practical unit, and is not dimensionally homogeneous , and so is used only in this field.

    en.wikipedia.org/wiki/Langmuir_adsorption_model

    The Freundlich isotherm is the most important multi-site adsorption isotherm for rough surfaces. =, where α F and C F are fitting parameters. [14] This equation implies that if one makes a log–log plot of adsorption data, the data will fit a straight line. The Freundlich isotherm has two parameters, while Langmuir's equations has only one ...

  5. Monolayer - Wikipedia

    en.wikipedia.org/wiki/Monolayer

    A Langmuir monolayer or insoluble monolayer is a one-molecule thick layer of an insoluble organic material spread onto an aqueous subphase in a Langmuir-Blodgett trough. Traditional compounds used to prepare Langmuir monolayers are amphiphilic materials that possess a hydrophilic headgroup and a hydrophobic tail.

  6. Langmuir–Blodgett trough - Wikipedia

    en.wikipedia.org/wiki/Langmuir–Blodgett_trough

    The idea of a Langmuir–Blodgett (LB) film was first proven feasible in 1917 when Irving Langmuir (Langmuir, 1917) showed that single water-surface monolayers could be transferred to solid substrates. 18 years later, Katharine Blodgett made an important scientific advance when she discovered that several of these single monolayer films could be stacked on top of one another to make multilayer ...

    en.wikipedia.org/wiki/Langmuir–Taylor_detector

    A Langmuir–Taylor detector, also called surface ionization detector or hot wire detector, is a kind of ionization detector used in mass spectrometry, developed by John Taylor [1] based on the work of Irving Langmuir and K. H. Kingdon.

    Langmuir (unit), a unit of exposure of an adsorbate/gas to a substrate used in surface science to study adsorption; Langmuir Cove, a cove in the north end of Arrowsmith Peninsula, Graham Land, Antarctica; Langmuir monolayer, a one-molecule thick layer of an insoluble organic material spread onto an aqueous subphase in a Langmuir-Blodgett trough

  9. Heisler chart - Wikipedia

    en.wikipedia.org/wiki/Heisler_Chart

    These first Heisler–Gröber charts were based upon the first term of the exact Fourier series solution for an infinite plane wall: (,) = = [⁡ + ⁡ ⁡], [1]where T i is the initial uniform temperature of the slab, T ∞ is the constant environmental temperature imposed at the boundary, x is the location in the plane wall, λ is the root of λ * tan λ = Bi, and α is thermal diffusivity.
