Schematic showing property changes

Fig. 12. Schematic pattern of changes in the f-element properties plotted as a function of L-values (open circles connected with the solid lines). Dashed lines connecting full points within the second and fourth segments show the inclined W plot...

We can also classify the systems based on the states of the reactants and products. Monofunctional monomers such as benzyl acrylate are liquids and produce liquid polymers, and we call these Tiquid/liquid systems. Figure 1 shows a schematic of the changes in properties across a liquid/liquid front. Multifunctional monomers such as 1, 6 hexanediol diacrylate (HDDA) are liquid but produce a thermoset, solid product, and these we call liquid/solid systems. Finally, solid monomers such as acrylamide (8,25) and transition metal nitrate complexes of acrylamide (26-28) can be polymerized frontally in solid/solid systems.

It is perhaps also worth stressing that different properties change with cure time in different ways. Such differences are illustrated schematically in Fig. 8. Figures 9,10 and 11, show specifically the effect of altering the type and amount of acceleration on the optimum cure time, tensile strength and modulus of compounds based on oil-extended SBR. 

The shape of the breakthrough curve is depending on the behavior of the so called mass transfer zone (MTZ). Figure 242 shows schematically the MTZ within a packed bed of adsorbent. Within the MTZ the properties of the incoming air are changed to the outlet air properties. 

The Implementation property shows that the model for this diode is Dbteah. Suppose we want both Zener diodes in the circuit to use the model Dln4734A. Change the Implementation property to Dln4734A and type CTRL-F4 to close the spreadsheet and return to the schematic. In the schematic, the text Dbreak will change to D1H4734A ...

More recently, Tohidi and coworkers (Burgass et al., 2002 Mohammadi et al., 2003) have applied a novel method for measuring gas hydrate phase equilibria (Lw-H-V), which is based on a Quartz Crystal Microbalance (QCM). Figure 6.3 shows a schematic of the QCM set up and the QCM placed in a high pressure cell. The QCM consists of a thin disk of quartz sandwiched between two electrodes. The crystal will oscillate at a particular resonant frequency when an electric current is passed across the electrodes. This frequency is a function of the properties of the crystal. Any mass (from hydrate formation) attached to the surface of the crystal disk will cause a change in the resonant frequency, and hence be detected. The pressure and temperature of the system is measured using conventional methods, namely, a pressure transducer and a thermocouple in the high pressure cell.

Pore structures of membranes formed in a primary process can be modified by subsequent modification processes to change properties and to obtain tailor-made systems for specific applications. Figure 2.4 shows schematically some typical microstructures.
