Fig. 5. Silver haUde grain morphologies for (a) cubic, precipitated in an environment having a silver ion concentration, [Ag" ], of ca 2.5 x 10 mol/L (b) octahedral, ca 6.0 x 10 mol/L and (c) tabular microcrystals, ca 1.0 x 10 ° mol/L. A cross section of a tabular grain revealing double parallel twin planes... Fig. 5.

This problem can be overcome by using grain morphology to distinguish between quartz, clay and other minerals. A secondary problem occurs as the low density of the coal matrix allows for a beam penetration to a depth of approximately 10 ym. This means that the BSE image represents a surface volume rather than just a plane. [Pg.26]

PTCDA films OMBD-grown on Ag(lll) single crystals show a transition from layer-by-layer growth with smooth and small-grained morphology towards the... [Pg.212]

When the PTES/TEOS ratio exceeds 1 4, a hexagonal mesophase is again formed. SEM observation of the 1 1 powder shows two types of grain morphology aggregates of facetted... [Pg.292]
