Pd/Y matrix sample

Fig. 69. Optical transmittance images of Pd/Y matrix sample [schematic representation shown in inset of (v)] at (i) 1, (ii) 1.5, (iii) 2.5, and (iv) 9.2 s after exposure to 1 bar of H2. In the area depicted Dy and Dpd increases stepwise from 0 to 150 nm and 1 to 25 nm, respectively, (v) Optical transmittance vs. time curve for a typical plaquette (marked white, with Dpd = 10 nm, >y = 100 nm). The points marked 1-4 are taken from (i)-(iv), respectively...
