There is a fantastic opportunity for a post-doctoral researcher to join the group for 24 months, with an ideal start date in January 2020. The position is funded by the Leverhulme Trust, who awarded one of their fantastic prizes in Chemistry to Tom this year.
Full details can be found in the job description below:
Applications close on 21st November 2019, and please do get in touch with Tom directly by email for informal enquiries.
Well done to Chris for publishing his first, first author paper in the Journal of the American Chemical Society!
Metal–organic framework crystal-glass composites (MOF-CGCs) are materials in which a crystalline MOF is dispersed within a MOF glass. In this work, we explore the room-temperature stabilization of the open-pore form of MIL-53(Al), usually observed at high temperature, which occurs upon encapsulation within a ZIF-62(Zn) MOF glass matrix. A series of MOF-CGCs containing different loadings of MIL-53(Al) were synthesized and characterized using X-ray diffraction and nuclear magnetic resonance spectroscopy. An upper limit of MIL-53(Al) that can be stabilized in the composite was determined for the first time. The nanostructure of the composites was probed using pair distribution function analysis and scanning transmission electron microscopy. Notably, the distribution and integrity of the crystalline component in a sample series were determined, and these findings were related to the MOF-CGC gas adsorption capacity in order to identify the optimal loading necessary for maximum CO2 sorption capacity.

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:

We are based in the Department of Materials Science and Metallurgy (University of Cambridge), and focus on the the intersection of the hybrid material and amorphous domains. We also work on the thermo-mechanical properties of crystalline framework materials.
