Therefore, the optimizations in this work were performed using the ωB97XD functional. Based on the optimised structure, the single-point energy was obtained at the ωB97XD/def2-TZVPP level.
WebbTheoretical Density = actual density (fresh unit weight) / theoretical x 100 = calculated air content Since the theoretical density from the lab has no air, you are comparing that laboratory weight to the fresh weight which contains air. The air in the fresh weight sample makes it lighter than the theoretical. WebbTherefore, the theoretical density ρ0 of powders is 6.081 g/cm2 according to the calculation result of Eq. (12). It is very close to the density 6.111 g/cm2 which comes from the formula d=6/(ρSBET) [20], where d is the particle size, ρ is the density of the powers, SBET is the BET surface area.
