Deposition rate reflection factor

I860 and the mid-1990s, areal deposition rates in the coastal waters increased by more than a fector of 10 and in open ocean regions by at least a factor of 2, particularly in the North Atlantic. The aeolian deposition pattern now reflects transport via the Westerlies from North America to Europe and via the Trade Winds from Africa to South America. 

Near the origin of the graph, the film growth rate is proportional to the sulfur incident rate, r(i, S). The slope in this region is approximately equal to the value of the sulfur reflection factor, 8(S), that was obtained from a nonlinear least-square fit of equation 40 to the experimental data. Thus, in the sulfur-limited regime, the deposition rate of ZnS is given by r(d, ZnS) 8(S) r(i, S), in which 8(S) 0.5. 

Similarly, at a high sulfur incident flux, the deposition rate becomes independent of the sulfur flux. Where the curves are horizontal in Figure 13, the deposition rate is 70% of the zinc incident rate, a fraction that is very close to the Zn reflection factor, 8(Zn), that was obtained from the least-square fit. In this Zn-limited regime, the deposition rate is given by r(d, ZnS) 8(Zn) r(i, Zn), in which 8(Zn) 0.7. 

Figure 16.3 The interaction potential between a high-aspect-ratio object and a surface of like electrostatic charge contains a barrier. This barrier height varies with surface potential (a] and Debye length (bj. Thus these two factors can be employed to modulate deposition rate. Modeling parameters reflect experimental conditions for a complete set see the text. ...

The linear plot in Figure 7 of log( —j<—) (see Table 2, footnote g) and the Taft-Hammett (23) ap parameter for these complexes Ru(bpy)2(4 -X-stilb)2 + arises because the increasing ap parameter reflects the more anodic redox potential for the vinyl ligand, which results in a greater concentration of initiator, a more rapid polymerization reaction, and hence a greater amount of polymer deposition on the electrode surface. Such a correlation is indeed remarkable because it implies a greater surface coverage per unit time only if factors such as steric bulk, polymer conformation and rate of polymer precipitation remain relatively constant for the substituted trans-stilbazole series. 

The rate of evaporation of the molecule is influenced by many factors. For example, urinary volatiles are released in an aqueous solution, and the rate of loss of water from the deposit (and thus, local airflow and humidity) will affect the rate of drying, and the loss of those volatiles. The deposition pattern may reflect an awareness of the need to replenish a signal site— it is reasonable to assume that the frequency of replenishment is related, at least in part, to the rate of loss of the signal. To illustrate, the need to sustain a signal over an extended period might result in the repeated deposition of mouse urine in posts (Figure 1).
