Efficiency faster with increasing temperature

Effect of Temperature. The effect of tenqperature on the rate of CH formation at a single Ru electrode at -0.545 V vs SCE is shown in Figure 6 the data are listed in Table 3. The inset illustrates a plot of faradaic efficiency vs tenqperature. It is note worthy that an efficiency of 42% at 80 C is the highest recorded for CH formation. The increase in the faradaic efficiency for CH formation indicates that CH formation increases faster with temperature than... 

Figure 2.2 Efficiency as a function of the linear velocity of the carrier gas — viscosities of carrier gases. These are typical Van Deemter curves showing that hydrogen, of the three gases studied under the same conditions, allows a faster separation, conveying a greater flexibility in terms of the flow rate, which is very useful for temperature programming. Note the increase in the viscosity of these gases with the temperature and that helium is more viscous than nitrogen at the same temperature.

In general, dialysis proceeds faster at room temperature than at 4°C. However, depending on the dialysis time, it may be prudent to conduct dialysis at lower temperature to prevent spoilage and loss of functionahty. Thermal stabihty of the molecule should also be considered in temperature selection. Pore size of dialysis membranes must be carefully selected in accordance with the protein of interest. Although dialysis is an efficient way to increase protein purity at the analytical scale, it is less practical at the industrial scale, and therefore other techniques, such as diafiltration and chromatography, may be of greater interest.
