  2. Simon–Glatzel equation - Wikipedia

    en.wikipedia.org/wiki/Simon–Glatzel_equation

    The Simon–Glatzel equation [1] is an empirical correlation describing the pressure dependence of the melting temperature of a solid.The pressure dependence of the melting temperature is small for small pressure changes because the volume change during fusion or melting is rather small.

  4. Specific ion interaction theory - Wikipedia

    en.wikipedia.org/wiki/Specific_ion_interaction...

    In theoretical chemistry, Specific ion Interaction Theory (SIT theory) is a theory used to estimate single-ion activity coefficients in electrolyte solutions at relatively high concentrations. [ 1 ] [ 2 ] It does so by taking into consideration interaction coefficients between the various ions present in solution.

  5. BET theory - Wikipedia

    en.wikipedia.org/wiki/BET_theory

    BET model of multilayer adsorption, that is, a random distribution of sites covered by one, two, three, etc., adsorbate molecules. The concept of the theory is an extension of the Langmuir theory, which is a theory for monolayer molecular adsorption, to multilayer adsorption with the following hypotheses:

  7. Ion source - Wikipedia

    en.wikipedia.org/wiki/Ion_source

    Chemical ionization (CI) is a lower energy process than electron ionization because it involves ion/molecule reactions rather than electron removal. [6] The lower energy yields less fragmentation, and usually a simpler spectrum.

  8. Aconitic acid - Wikipedia

    en.wikipedia.org/wiki/Aconitic_acid

    Aconitic acid refers to organic compounds with the formula HO 2 CCH 2 C(CO 2 H)=CHCO 2 H.A white solid, it is classified as a tricarboxylic acid. The two isomers are cis-aconitic acid and trans-aconitic acid.
