Water structure in 'water-in-salt'and 'water-in-bisalt' electrolytes
This is a continuation proposal aiming to explore the local structure around water in 'water-in-salt' and 'water-in-bisalt' systems by performing a first difference experiment in samples prepared with H2O and D2O. A first experiment has been performed in D3 (6-02-577), but the data correction procedure is not straightforward and the limitations in the accessible low-Q range and the statistical quality of the data make difficult to obtain accurate information. Therefore, we ask for 3 days of beam time in D7 in order to obtain good data at low Q and 1 day in D4 to obtain the complete S(Q) for the deuterated samples. The new data will serve also as a reference to analyse unambiguously the D3 data, providing a set of reliable S_HX(r) and g_HX(r) functions that will be used to determine the ordering of the ions around water.
