What is it about?
A 'water wire' is a linear chain of water molecules. This unique structure is found in a porous mineral called bikitaite. We nicknamed the water chain 'one-dimensional ice' because of its stability inside the porous host. At ambient temperature, the behaviour of the water wire is more similar to ice than to liquid water: the molecules do not diffuse, and the linear chain is maintained. In this work, we wanted to understand why this peculiar water wire is stable inside bikitaite.

Why is it important?
We explained why this porous material can stabilize this unique water wire: each pore fits the water chain like a glove, and there are favorable interactions between the chain and the host material.
