We are “film-makers.” We videotape how tiny machineries of materials and living cells move, interact, assemble and transform in a fluid medium to perform their functions. Sometimes atomic resolutions are involved to track the paths of ions and atoms in charge conduction or chemical reactions. We also utilize deep learning-based analysis to extract the underlying physical rules encoding such dynamics. The systems are diverse, ranging from batteries, separation membranes, colloids to membrane proteins (click
