Dear all,
Quite a few crystallisation conditions in the screens feature
'sodium/potassium phosphate'. I'm curious to know why such a Na/K mix
is there. As the pH is mostly determined by the (H2PO4)- to (HPO4)2-
ratio, is there such a need to have both cations? If so, is the Na to
K ratio important
Hi,
From my rather limited experience ...
Is your EXAFS data collected on a crystal or in solution? If the
latter, it is worth remembering that the chemical environment in
solution and in crystal can be different. Moreover, atomic coordinates
and bond distances determined via crystallography a
