- Abstract
- We investigate whether an interpretation of waters thermodynamics [Science,
319, 582 (2008)] by using analogy with the binary metal alloys l-type ordering
transition or buckminsterfullerenes orientational-ordering transition has merit.
On examining the heat capacity data used for the nanoconfined water, the
construction of the heat capacity peak, and the number of water molecules in
nanoconfinement, we find that (i) the peak had been obtained by joining the data
for emulsified water with that of the nanoconfined water and (ii) only three water
molecules can be fitted across the 1.1 nm diameter pores used in the study, two
of which form a cylindrical shell that is hydrogen bonded to silica. The remaining
connectedness of one water molecule would not produce a metal alloy-like l-
transition, or cooperative motions. Therefore, there is no basis for considering
such an ordering in supercooled water. (literal)
