Resistance of solutions

Fig. 1.69 Effect of resistivity of solution on the distribution of corrosion on the more negative metal of a bimetallic couple, (a) Solution of very low resistivity and (b) solution of very high resistivity. Note that when the resisitivity is high the effective areas of the cathodic and anodic metals are confined to the interface between the two metals...

The scale-up of a fixed-bed separation may be carried out by increasing the diameter of a column, the length of the packed bed, and/or the flow rate of the feed solution. The pressure drop through the column limits the length of the packed bed. The amount of adsorbate treated per unit time and the unit sectional area of a column will increase with the linear velocity of the feed. However, the slope of the breakthrough curve becomes gentle with an increase in the velocity, when the intraparticle resistance of solute transfer is dominant, and thus the fraction of the column capacity available at the break point will decrease. Therefore, the linear... 

The hydrodynamic resistance of solutions of connective-tissue polysaccharides has been measured by sedimentation techniques [9] the resistance is expressed as the hydraulic conductivity (k), which was defined in Equation 6-9 (Figure 6.8). This analysis permitted the identification of two different groups of polysaccharides those compounds containing Pi 4- and y6i 3-link-ages (such as chondroitan sulfate, keratan sulfate, and hyaluronate) had lower hydraulic resistance than compounds containing some fraction of... 

Low production costs, technical application properties, high water solubility, and cold-resistance of solutions are the reasons which determine the high importance of this surfactant group, which has the consumption amounts in the Federal Republic of Germany as shown earlier in Figure 22.2. 

Hence, association constants of metal ions in such SAMs, determined from changes in the charge-transfer resistance of solution redox couples, are similar to those calculated from capacitance data.

Soon after vinyl BR s were first introduced commercially, it was recognized that the vinyl structure imparted non-typical dynamic properties. In particular, their vulcanizates showed improved resistance to heat build-up when compared to emulsion SBR. j O Before relating the special contribution of the vinyl structure to properties, it is informative to first determine the influence of styrene content (at constant vinyl) on the two fundamental properties of interest Tg and tan 6, as shown in Figure 14. As expected, both Tg and tan 6 increase almost linearly with styrene content. Thus like a conventional tire tread rubber, the rolling resistance of solution SBR s prepared using lower amounts of styrene is accompanied by a decrease in the wet traction of the rubber.
