- Multimodal Synchrotron X–ray Insights into Materials Kinetics for Energy Applications
Abstract
Understanding the kinetics of materials is crucial for predicting their evolution under processing and operating conditions, particularly in energy–related applications where morphology, chemistry, and structure change dynamically across multiple length scales. Synchrotron X–ray techniques–integrating imaging, spectroscopy, and diffraction as a multimodal approach–offer unique capabilities to capture these transformations in situ and operando. This talk will highlight recent progress in applying synchrotron–based X–ray microscopy, complemented by multimodal analyses, to a range of functional systems for energy–related applications. Examples include electrochemical energy storage materials, where in situ studies reveal electrode evolution during cycling; thermochemical energy storage systems, where X–ray probes track morphological changes and phase transitions during redox cycling; and bicontinuous nanomaterials created by dealloying, where autonomous experiments integrating scattering and spectroscopy resolve structural evolution in real time. I will also discuss molten salts, where multimodal X–ray methods uncover interfacial processes under extreme conditions relevant to next–generation nuclear reactors and solar power plants. Together, these studies demonstrate how synchrotron X–ray approaches provide critical insights into materials kinetics, guiding the design of advanced energy materials.
