The Langmuir theory of adsorption only applies to forming a monomolecular layer of gas molecules on a solid surface. The theory of adsorption proposed in 1938 by Brunauer, Emmett and Teller is known as the BET theory. They assume that physical adsorption resulting in the formation of multilayers is the accurate picture of adsorption.The BET equation (named after Brunauer, Emmett, and Teller who developed the theory) was first published in 1938 (Brunauer, 1938), and continues to be the most widely used method to determine the number of molecules/atoms of a gas needed to form a monolayer, X m, of adsorbed gas on a solid surface (Thommes, 2015).The BET equation (Equation .The BET theory has been successfully used to det. porous catalysts' and fine powders' sp. surface area to this day. In contrast, applying the BET and GAB equations to water vapor sorption by solid foods (and non-foods) has at least three major problems: The calcd. food powders' sp. surface area is independent of their particle size; the . AI-enhanced description. BET theory seeks to explain the physical adsorption of gas molecules onto solid surfaces and extends the Langmuir theory of monolayer adsorption to multilayer adsorption.

At the heart of this sits the Brunauer–Emmett–Teller (BET) theory, which has been a remarkably successful contribution to the field of materials science. The BET method was developed in the 1930s for open surfaces but is now the most widely used metric for the estimation of surface areas of micro- and mesoporous materials. Despite .
To systematically assess the characteristics and potential utility of the Guggenheim–Anderson–de Boer (GAB) formulation of the Brunauer–Emmett–Teller (BET) equation from physical chemistry for modeling dose-responses in pharmaceutical applications. The GAB–BET equation was derived using pharmacodynamic first . The Brunauer-Emmett-Teller (BET) model is a model of adsorption that allows molecules to adsorb in more than just a single layer on the surface. The Brauner–Emmett–Teller (BET) theory was originally based on adsorbing surfaces of zero curvature. The theory is elaborated to include a curvature parameter. The theory has been developed for mono-size dense particles (spherical or rod-like) and porous materials with a sharp pore size distribution (spheric 2023 PCCP HOT .BET Theory 技術情報 技術情報・アプリケーション. この理論はII・IV型等温線の場合、相対圧0.05～0.35の間でよく成り立ち、その間のデータを最小二乗法し、傾きと切片より単分子層吸着量（Vm）とCパラメータを求める。bet theory BET MULTILA YER ADSORPTION THEORY 43. The model sets a theoretical basis for calculating the surface area of the solid. The theory was derived on the assumptions that (1) the Langmuir equation. The BET method can be used for the characterization of various. types of microporous materials including zeolites, [91–93] pho-. tocatalysts, [94–99] polymers,[100–102] and photoelectrodes .
The surface area is one of the most important quantities for characterizing novel porous materials. The BET analysis is the standard method for determining surface areas from nitrogen adsorption isotherms and was originally derived for multilayer gas adsorption onto flat surfaces. Metal−organic frameworks (MOFs) are a relatively new . The BET equation is used for determining the surface area of solids from the nitrogen sorption isotherm at liquid nitrogen temperatures, but the equation has also been used with a wide range of other gases and vapours. .
