Abstract
Functional materials are central to many technologically important devices and systems, including sensors, electronic devices, and energy storage and delivery. Such materials are often multifunctional and highly responsive. Developing experimental approaches that specifically target functional materials is essential to obtaining the atomic-level mechanistic understanding that leads directly to their advancement. This is particularly relevant given the increasing power and speed of characterisation instrumentation, allowing real-time and non-equilibrium measurement of the material during operation to be made. This presentation will give examples of the application of X-ray and neutron techniques of analysis, in combination with computational density-functional-theory-based methods, to understand materials function [1]. Example studies for a range of functional materials will be presented, covering experimental approaches that will include real-time studies of electrodes during battery operation (structural changes accompanying wide-range compositional variation) [2–3], as well as studies of porous framework materials applied as sorbents (gas-adsorption and temperature
effects) and with interesting mechanical properties (pressure-dependent studies) [4–6].
