Behavior as a function of temperature and pressure

In the present case, we have to take four different parameters for each metal, that is AH, AHK° and K,.  

To avoid certain aberrant valnes peculiar to this device, and to shorten the calculations, we can impose these conditions  

The first two conditions stem from the fact that the positive pole of the device is gold, and we can admit that, in general, the species fixed at the three boundary point are more active and, subsequently, less bonded with gold than with platinum 

The third condition is linked to the fact that here, A//, is negative. 

The adopted calculation process allows us to reproduce, with accuracy, the complex behavior of the sensor as a function of temperature and pressure the difficulty involves the simulation of a peak on the curves displaying the signal as a function of temperature and the simulation at the intersections of curves displaying the influence of the pressure on the signal.

High viscous homogenous mixtures such as polymer blends of well defined components are often difficult to prepare and even more problematic is a production of the relative big sample quantities necessary for some conventional investigation methods. Hence there are demands for "mini method", especially for a method to determine the phase behavior as a function of temperature and pressure. This task is solved to one part by the recently developed "mini extruders" of DSM (1), which enable a very good premixing of small amounts of polymer samples. 

The phase behavior as a function of temperature and pressure is compared to experimental data in panel (b) of Fig. 32. One clearly observes that the critical line does not connect to the critical point of CO2, an indication for type III phase behavior. One also finds that the critical line shifts to higher pressures as we reduce the compatibility of the two components. The simulation data of our coarse-grained model agree with the experimental data reasonably well. The experiments, as well as both equations of state, measure a sharp increase of the critical pressure at low temperatures. Unformnately, the minimum of the critical pressure could not be observed in our simulations, because the liquid— liquid immiscibility occurs at rather large densities making the insertion/deletion of the polymer prohibitively difficult.
