MATERIALS SCIENCE RESEARCH
Traditional methods of characterizing the size, morphology and reactivity of nanomaterials often only provide static “snapshots” and require an iterative series of measurements for each condition. With Protochips’ workflow-based in situ TEM solutions, you can utilize the electron microscope to directly observe nucleation and growth, grain boundary migrations, particle-particle interactions, and more.
