Nonporous schematic representation

Figure 15.2 Schematic representation of different electrochemical cell types used in studies of electrocatalytic reactions (a) proton exchange membrane single cell, comprising a membrane electrode assembly (b) electrochemical cell with a gas diffusion electrode (c) electrochemical cell with a thin-layer working electrode (d) electrochemical cell with a model nonporous electrode. CE, counter-electrode RE, reference electrode WE, working electrode.

Figure L General schematic representation of transport through hydrophobic nonporous membranes, where A represent charged small molecules, B small molecules able to diffuse through the membrane and C big molecules, AC is the difference in concentration gradient across the membrane.

Fig. 1. Schematic representation of typical physisorption isotherms T5rpe I (microporous materials), type II (nonporous or macroporous materials), and t5rpe IV (mesoporous materials).

Figure 32.20 Schematic representation of light-transfer paths in nonporous Ti02 (a) and hierarchically macro/mesoporous Ti02 (b).
