The effect of temperature on the size distribution of the Au nanocrystals can be readily seen from the TEM images in Figure 2. The mean diameters of the nanocrystals formed at 30, 45, 60, and 75 °C are 7, 10, 12, and 15 nm, respectively, but the interparticle separation remains nearly the same at 1 nm. X-ray diffraction measurements show that with increase in temperature, the crystallinity of the film increases (Figure 3). The films obtained at 45 and 60 °C exhibit prominent (111) peaks (d = 2.33 A), while those obtained at 30 °C show weak reflections, probably due to the small particle size. The growth of the (111) peak with temperature indicates an increase in the particle size.

It is proportional to the flux jn i(Pi) of generation n — 1 incident at P times the reflection probability r = 1 — / . Furthermore, because we assume a cosine angular distribution of reflected particles, it is proportional to cos8. As the flux is defined as the number of particles per unit time and unit area normal to the surface also cos 82 enters. Finally, in the two dimensional case the distance d 2 between P and P2 enters with the power ( — 1). We obtain... 

The AGf corresponding to our average Kg is r 737 g 4.2, which is considerably less negative than the value estimated with AHf and our estimated entropy. The entropy that schuetteite would have to have if AG were -737.g and the NBS value for AH were correct is between 208 and 237 J K mol , the range reflecting probable error in the solubility data alone. This value differs from our estimated value by more than our expected error, leading us to suspect possible error in either the solubility data or the NBS AHf in addition to error in the estimated entropies. Ordinarily we would prefer the experimentally based AG derived from Kg over an estimate, but in this case there is sufficient question about the experimental methods (e.g., no test for equilibrium is described) that we prefer to select a probable range for AG9, -737 to -752 kJ mol . ...

Figure 1 Comparison of reflection probabilities calculated for two one-step potentials with two different procedures. Pull curves with matching of Gordon- Volkov waves on both sides of the discontinuity. Rn means reflection probability with absorption (n > 0) or emission (n < 0) of quanta. Dashed curves matching of Gordon-Volkov waves with free waves. Left column a one-step potential taken from [10]. The height of the step is 2 a.u. the mass of the particle is that of a free electron. The frequency of the oscillating electric field is 0.1 a.u. and its peak amplitude 0.02 a.u.. The number of channels is 27. Right column a one-step potential which is part of the potential studied in Section IV. Height 0.017 a.u. mass 0.07 mo frequency 0.0025 a.u. peak field amplitude 1. 10 5 a.u. number of channels 11.

The results obtained in this work are related mainly with the high rates for the reduction process achieved with this kind of electrodes. With Co phthalocyanine electrodes the only significant products were CO and H2 and the results are highly dependent on the potential used for the electrolysis experiments. Other important factor described by the authors was the amounts of carbon monoxide and hydrogen produced from sample to sample, reflecting probably variations in the exact composition of different Co phthalocyanines electrodes. For Mn, Cu, and Zn impregnated electrodes both formic acid and hydrogen were produced. 

With regard to our restricted knowledge of the interaction of gas molecules with a liquid surface we use Maxwell s suggestion C7] dividing the non-con-densed part of the incident particle flux into a speculary reflected and a diffusively reflected fraction. Experimental results C8,9] indicate that the evaporation coefficient of pure liquids is nearly unity, i.e. the reflection probability is very small. Consequently an approximative treatment of the reflection problem using Maxwell s method turns out to be sufficient.
