... small angle x-ray scattedng and by energy fittered bliaDsmiSSion eiectron mkmscopy. All experimentS show domains in the range of 1 to loo0 nm and domain size can be controlled by the extent of coordination of the d e groups by the zinc ions and by themd history. The different morphological expsliments lead to an apparent hierarchy of domain sizes. The NMR experiment yields the smallest domains, 2 t~ 10 m, where; contrast is produced b diffemccs dcroscopy indicates domains in the range of 100 to lo00 nm.
