MC Seminar hosted by Prof. Peter Slater

An in-depth understanding of the structure – property relationships is essential for the successful discovery and preparation of new functional materials capable of overcoming the limitations of the currently used ones. As materials’ complexity increases, structural characterisation using a range of scattering-based and complementary techniques and state-of-the-art data analysis approaches, aided by computational simulations, is essential in providing this insight.

This presentation will give an overview of our recent work on new structural characteri-sation methodologies and their applications to extended and molecular materials across the chemical spectrum: from mixed metal oxides to functional organics. In particular, the focus will be on the development and use of advanced structural data analysis methodol-ogies capable of tackling exceptionally complex crystallographic problems arising from phase transitions in functional materials. Where applicable, the examples will also illus-trate the complementary use of long-range and local structural probes in understanding the structure, properties, disorder and dynamics.
