Au nanotubule membranes with the following approximate nanotubule diameters were used to obtain the majority of the data reported here i.d. = 28 1, 7.0 0.1, 1.9 0.1, and 1.5 0.2 nm. Figure 19 shows permeation data for transport of pyridine through these various membranes. Data for membranes derivatized with both the R = -C2H4-OH (upper solid curve) and the R = -C16H33 (lower dashed curve) thiols are shown. The corresponding flux data are shown in Table 3. As would be expected [114], the flux of pyridine decreases with decreasing tubule diameter for both the...

Data taken from both reverse osmosis ( ) and pervaporation (O) experiments. Feed-side and permeate-side membrane concentrations, Ci0 m) and Cie m), calculated from the operating conditions through Equations (2.26), (2.36) and (2.76). Maximum flux is obtained at the maximum concentration difference, when the permeate-side membrane concentration cit(m)), equals zero [19].

The roule (raveled by a Ca channel blocker, such as verapamil, (o its receptor site parallels (hat observed with many local aneslhetic-like antiarrhythmic agents. It i.s believed that verapamil, like mo.sl of (he Ca channel blockers. crosses the cell membrane in an uncharged form to gain access to its site of action on the intracellular side of the membrane. Data show a greater affinity of verapamil and other Ca- channel hlockers to the inactivated. state of the channel. ...

Membrane permeance and selectivity data are based on those of polymeric membranes obtained from Faiz and Li (2012). This is due to a lack of studies on CMS membranes for the separation of olefins/parafifins. The assumption of the use of polymeric membrane data is conservative since CMS membranes have been shown to give better permeance and selectivity than polymeric membranes for olefln/paraffin separation (Xu et al., 2012)...
