Development of information and energy technologies beyond-Moore computing and internet of things applications requires both acceleration of material development as well as fundamentally new approaches for controlling matter on sub-10 nm scales. Recent progress in scanning probe and electron microscopies have opened the pathway to explore structure and functionalities on atomic and subatomic scale, providing vital feedback to device fabrication and processing. These advances bring forth the challenges of extracting relevant physical and (electro)chemical behaviors that can be linked to preparation pathways and predictive theory. 

The opportunities opened by synergy of physics-informed big data and machine learning techniques with imaging to probe materials behavior, as exemplified by thermodynamics of solid solutions from the atomically resolved images of atom distribution, flexoelectric coupling from topological defects in ferroics, and reaction-diffusion constants from STEM movies of electrochemical growth will all be discussed. The use of electron beam probes to explore atomic-scale reactions and phase evolution and assembly of matter atom by atom will also be further delineated.
