How to make medium-density amorphous ice (MDA).

Check out the paper in Science here: https://www.science.org/doi/10.1126/scienc...

By repeatedly shearing hexagonal ice we can create MDA.

This new form of ice is amorphous.

Unlike ordinary crystalline ice 🧊 where the molecules arrange themselves in a regular pattern, in amorphous ice the molecules are in a disorganised form that resembles a liquid.💧

Amorphous ices have long been suggested as models for liquid water.

The new form of amorphous ice we discovered has a similar density to liquid water (unlike all other ices), and very closely resembles liquid water!

We named the new ice medium-density amorphous ice (MDA).

Our discovery of MDA raises many questions on the very nature of liquid water!

Excitingly it may also exist in the icy moons of Jupiter and Saturn... 🪐🌝
