The results of permeability also show high amounts up to 128 Barrer (1 Barrer = 1 × 10−10 [cm3 (STP) cm/cm2 s cm Hg]), and high selectivity for carbon dioxide with respect to nitrogen (CO2/N2: 27).
The dual-layer MMMs exhibited excellent improvements in CO2 permeability of over 3000% from 46.2 to 1430.9 Barrer (1 Barrer = 1×10−10 cm3 (STP) cm /cm2 s cmHg) with a CO2/N2 selectivity of 22.4, which was only slightly below the upper bound (2008).
Permeabilities are reported in units of Barrer (1 Barrer = 1 × 10−10 cm/(STP) cm2(cm2 s cm Hg)).
Membrane permeability, P i (Barrer; 1 Barrer = 10-10 cm3 (STP ·cm·cm-2·s-1·cmHg-1), was defined as [1, 17 19] P i = d N i Δ p i A, where N i (mol·s-1) is the permeate flow rate of component gas i, Δp i (in Pascals) is the transmembrane pressure difference of i, and A (in square centimeters) is the membrane area.
PBI has attracted attention due to its thermal stability and good processability but it has poor performance at 30 °C (P H2 = 1 Barrer; α(H2/CO2) = 15), although this improves markedly at 250 °C (P H2 = 100 Barrer; α(H2/CO2) = 22).

But Barre had incurred the hostility of the king's younger brother Prince John, and when John succeeded Richard as king in 1199, Barre ceased to be employed as a royal justice, instead returning to Ely and business in his clerical office.
PCR amplification was performed using Illumina Reagents followed by quantification and assessment of quality (as described above) along with high accuracy qPCR quantitation (KAPA Biosciences kit # 4824; Barre, VT).
