What is it about?
A 'water wire' is a zig-zag chain of water molecules running along one direction. This intriguing water structure actually exists inside a rare porous mineral - the zeolite bikitaite. We called the water wire 'one-dimensional ice', just because of its stability inside the porous host. Indeed, at ambient conditions, the behaviour of the water wire is more similar to ice than to liquid water: the molecules do not move away from their positions, and their ordered arrangement is preserved. Now the question is: what happens to the water wire at conditions different from the standard ones? Can the water chain resist to very high pressure?
Why is it important?
For the first time, we explored the effects of pressure on ordered chains of water molecules in nanometer-sized pores. With X-ray diffraction experiments and molecular dynamics simulations, we showed that the water chains still exist at high pressure conditions.
