Platinum-Palladium New Phenomenon
Experimentation with a combination of platinum and palladium to explore possible
improvements in the physical characteristics of IPMNCs has led to a peculiar phe-
nomenon. This phenomenon is basically depicted in the SEM picture of these new
types of IPMNCs in figure 3.42. As the x-ray scan indicates, the metallic particles
of Pt and Pd tend to deposit at a certain depth of about 25-30
m as shown in the
figure. We have repeated this experiment a number of times and have repeatedly
observed this phenomenon. We are still exploring an explanation as to why this
