Information we obtain is used to uncover mechanisms of work of vastly different nanoscale materials such as catalysts, electrocatalysts, solid oxide fuel cells, batteries, supercapacitors, phase change materials, and pyroelectrics. We are also developing a “reverse approach” that incorporates the data on macroscopic performance of such materials into their characterization scheme. We also include developments of new experimental and data analysis methodologies that rely on the use of combined techniques <em>in operando</em>, i.e., during a process in which a nanoscale material does useful work.</p> <div> <p><img class="fwd" alt="Image" src="images/sdan-projects.jpg" /></p> <p class="caption">Recent projects (from left to right): Development of multimodal characterization
