BET; BET
The BET method explains the physical adsorption of gas molecules on a solid surface and measures the specific surface area. It is based on the Brunauer, Emmet and Teller theory.
Cluster d'agrégats; aggregate cluster
A cluster is a deformable mass of aggregates that can be broken under stress. Its size varies according to the fractal dimension of the charge network.
CTAB ; CTAB
CTAB surface area is the specific surface area determined in accordance with ASTM D 3765 by adsorbing hexadecyltrimethyl ammonium bromide (CTAB) at pH = 9 and taking the projected area of the CTAB molecule to be 35 Å 2 .
Dimension fractale; fractal dimension
The fractality of a real object...
