Fig. 7. Schematic description of a polysiloxane at the monolayer—substrate surface (4). The arrow points to an equatorial Si—O bond that can be connected either to another polysiloxane chain or to the surface. The dashed line on the left is a bond in a possible precursor trimer where the alkyl chains can occupy...

FIG. 1 Schematic description of the relevant steps involved in a surface catalyzed reaction within the reactive regime. The cycle starts with the empty sites of the surface (top) and is followed by interactions between reactants and the surface (right branch). Such interaction finally leads to the reaction (bottom) and desorption of the products (left branch), a process which generates new empty sites (top). [Pg.389]

Figs. 70, 71 and 72 show schematic descriptions of the three latter above-listed methods. The main advantages and disadvantages of the methods were discussed in general by Volkov and Yazimirsky [294], for all types of molten salts. Regarding the application of the above-mentioned techniques in the investigation of molten fluorides, the following points should be mentioned. [Pg.168]

In Section I, a qualitative schematic description of the main connection between increased agitation intensity and increased total mass-transfer rate was given. It can readily be seen from this description that further research in gas and liquid flow patterns and in the area of relative bubble velocities in dispersions will contribute to the basic knowledge necessary for understand ing the real mechanisms occurring in these systems.

FIGURE 2.2. A schematic description of the evaluation of the transmission factor F. The figure describes three trajectories that reach the transition state region (in reality we will need many more trajectories for meaningful statistics). Two of our trajectories continue to the product region XP, while one trajectory crosses the line where X = X (the dashed line) but then bounces back to the reactants region XR. Thus, the transmission factor for this case is 2/3. [Pg.45]

Figure 4. Schematic description of the swelling process. The molecules of the swelling liquid start to penetrate inside the polymer framework from its surface (a) and to solvate the polymer chains. The polymer chain start to stretch out and to move away from one another the apparent volume of the polymer increases and the first nanopores are formed (b). Swelling stops when increasing elastic forces set up by the unfolding of the polymer chains counterbalance the forces which drive the molecules of the swelling agent into the polymer framework (c).

Fig. 3.4.1 Schematic description of the three-dimensional SPI technique. Gz, Cx and Gy are the phase encode magnetic field gradients and are amplitude cycled to locate each /(-space point. A single data point is acquired at a fixed encoding time tp after the rf excitation pulse from the free induction decay (FID). TR is the time between excitation (rf) pulses. Notice that the phase encode magnetic field gradients are turned on for the duration of the /(-space point acquisition.

Fig. 3.4.4 Schematic description of the one-dimensional double half k (DHK) SPRITE technique. The phase encode magnetic field gradient, Gz, ramped through half of /(-space beginning at the center and a single data point is acquired at a fixed time (tp) after the rf excitation pulse. The second half of /(-space is acquired after a 5T time delay. The time between rf pulses is TR.

Reservoir devices, as the name implies, are characterized by a core of drug, the reservoir, surrounded by a polymeric membrane. The nature of the membrane determines the rate of release of drug from the system. A schematic description of this process is given in Fig. 4, and characteristics of the system are listed in Table 3. [Pg.509]

Figure S.6. Schematic representation of So and Si energy profiles for DEWAR formation in TB9A and TB9ACN. 2 The excited state funnel F is very close to the ground stale surface and therefore leads to fluorescence quenching (identifiable with rate constant k). Most of the molecules return to the anthracene form via pathway a, while only a few proceed to the Dewar form (pathway b), because F is placed to the left of the ground state barrier. The steric effect of the tert-butyl substituent is indicated by the broken line. Without this prefolding" of the anthracence form. Dewar formation is not observed. The top part of the figure contains a schematic description of the butterfly-type folding process, while the bottom part contains examples of actual molecules.
