méthode Brunauer-Emmett-Teller

OBS: La théorie Brunauer, Emmett et Teller (BET) est une théorie physique. La méthode BET permet d’expliquer l’adsorption physique des molécules de gaz sur une surface solide et permet la mesure de la surface spécifique.
OBS: méthode B.E.T.; méthode BET : termes uniformisés par CN-AIR CANADA. (CN : Canadien National.)

OBS: B.E.T. method: Gaseous absorption analysis method. Acronym of ""S. Brunauer, P. Emmett, E. Teller."" Widely used for surface area determinations by computing the monolayer area.
OBS: The BET method is widely used in surface science for the calculation of surface areas of solids by physical adsorption of gas molecules.
OBS: Surface Area Measurement. For nanopowder, the B.E.T. method is commonly used to determine the specific surface area. The drop in nitrogen pressure in a closed container due to adsorption of the nitrogen molecules to the surface of the material inserted in the container is measured. (The shape of the nanopowder particles is assumed to be spherical.)
