The isotherms are applied to obtain surface area (SBET), mesopore
pore volume (Vmeso), total pore volume (Vt), the mesopore
fraction (Vmeso/Vt) is obtained by dividing mesopore
volume (Vmeso) with total volume (Vt).
A porosimeter (ASAP 2020 model from Micromeritics) was used to determine the BET surface area ([S.sub.BET]) - based on [N.sub.2] at 77 K (SKAAR, 1988) - the microporous area ([S.sub.M]), the Langmuir surface area ([S.sub.Langmuir]), the external surface ([S.sub.external]), the total pore ([V.sub.P]), the micropore ([V.sub.MP]) and mesopore
([V.sub.MSP]) volumes and the average pore diameter (D) of the C[O.sub.2] AC.
corresponding to intergranular pores are dominant, while the heavily cemented sandstones show large amounts of intercrystalline micropores.
Additionally, the mesopore
volume increased with an increase in silicate modulus, which also can explain the drying shrinkage increase as the silicate modulus increased (mentioned above in Section 3.5).
The relationship between the capacitive performance (specific capacitance and rate ability) and the texture property (SSA, micropore volume, and mesopore
volume) as well as the graphitization degree is also elucidated, which would largely benefit the design and practical application of such KAC materials in SCs.
The glutaraldehyde cross-linked Se-MCM-41 mesopore
composite has mixed with 3 mL of 2 mg x m[L.sup.-1] GOD solution in a phosphate buffer.
The Barrett-Joyner-Halenda (BJH) model applied to the adsorption branch of the isotherm was used to obtain the mesopore
Jain and coworkers obtained BET and mesopore
areas of up to 2440 and 1121 [m.sup.2] [g.sup.-1], respectively, after hydrothermal treatment of coconut shells with Zn[Cl.sub.2] and [H.sub.2][O.sub.2] at temperature of 275[degrees]C .
According to the literature , the pore of the clay can be divided into micropore (<0.04 [micro]m), fine pore (0.04~0.4 [micro]m), mesopore
(0.4 [micro]m~4 [micro]m), large pore (4 [micro]m~ 40 [micro]m), and macropore (>40 [micro]m).
In this study, we investigated the adsorption of tris(8-hydroxyquinoline)aluminum(III) (Alq), which has been studied as an organic light-emitting material , into the MPS films with different pore sizes (3.0 and 5.4 nm) prepared from cationic and nonionic surfactants to clarify the molecular aggregation/dispersion states of Alq at the film mesopore
Investigation into pore size distribution was performed while analyzing adsorption isotherms and using the model dependence of mesopore
