There has been significant interest in the dynamic processes of smart energy materials and devices, where the properties can be controlled by an external stimulus. The possibility for example to manipulate the electronic band structure, magnetic spin and catalytic properties of such materials opens a plethora of new applications. The nature of these dynamic materials requires operando microscopy techniques to characterize their physical properties while simultaneously measuring their functional performance. Recent technological and computational advances in transmission electron microscopy are transforming what dynamic material science processes and phase changes can be explored. The focus of this symposium is on the application of in situ/operando TEM techniques that include heating, biasing, cooling, magnetic fields and mechanical testing to induce and probe phase transitions in functional materials and devices at the nanoscale that, in synergy with theoretical methods, such as first-principles calculations, phase-field, micromagnetics, finite-element based modelling and simulations, help unravel the structure and properties of materials down to the atomic scale. Furthermore, as data collection, analysis and recording of dynamic information is becoming increasingly demanding, we also welcome contributions in computer-aided image analysis and big data processing, including based on artificial intelligence algorithms, to understand the fundamental physics governing the nano- to atomic-scale phase transitions of functional materials and devices.
