Brunauer-Emmett-Teller (BET)

The Brunauer-Emmett-Teller (BET) method is a way scientists measure the surface area of materials, especially porous solids like charcoal or powders. It works by analyzing how gases, such as nitrogen, stick to the surface at different pressures. By studying this gas adsorption, the BET technique determines how much surface is available for reactions or adsorption. This information is important for applications like catalysis, filtration, and material development, helping us understand and optimize the material's effectiveness based on its surface properties.
