## Description

- description: 'We have demonstrated that the process of hydrogen absorption into
    a solid experimentally follows a Langmuir-type (hyperbolic) function instead of
    Sieverts law. This can be explained by independent two theories. One is the well-known
    solubility theory which is the basis of Sieverts law. It explains that the amount
    of hydrogen absorption can be expressed as a Langmuir-type (hyperbolic) function
    of the square root of the hydrogen pressure. We have succeeded in drawing the
    same conclusion from the other theory. It is a 2-step reaction kinetics (2sRK)
    model that expresses absorption into the bulk via adsorption on the surface. The
    2sRK model has an advantage to the solubility theory: Since it can describe the
    dynamic process, it can be used to discuss both the amount of hydrogen absorption
    and the absorption rate. Some phenomena with absorption via adsorption can be
    understood in a unified manner by the 2sRK model.'
