Well done to Remo on publications in Nature Materials and J. Am. Chem. Soc. on the first high-pressure high-temperature phase diagrams of metal-organic frameworks.

The first looks at the negative melting slope of ZIF-62, i.e. why it becomes easier to melt with applied pressure:

The second looks at polymorphism in the ZIF-4 family, and shows the rich array of unusual phases which might be obtained by the simultaneous application of pressure and temperature:
