Symposium CM02—In Situ TEM Characterization of Dynamic Processes During Materials Synthesis and Processing
In situ imaging and spectroscopy techniques have emerged as primary tools for the characterizing the dynamics of materials formation. The development of in situ capabilities for TEM has led to rapid advances in our understanding of nucleation, growth, assembly and coarsening in colloidal, electrochemical, organic, macromolecular, semiconductor, biomineral and other solution-based systems. The development of electron beam correctors for TEM has led to sub-angstrom spatial resolution, thus enabling direct in situ observation of atomic motion during reaction processes and revealing atomic level formation and transformation mechanisms, including VLS growth of nanowires, oriented attachment of nanoparticles and electrochemically-driven growth of dendrites. The symposium will cover a broad range of topics related to in situ studies of materials formation including cluster formation and dynamics, particle nucleation, crystal growth, phase transformations, crystal defect formation and elimination, recrystallization, nanoparticle interactions and assembly, nanowire growth, polymeric, macromolecular and organic/inorganic self-assembly, chemical reactions, and interface dynamics in gases and liquids. The goal of this symposium is to bring together researchers from various fields utilizing in situ methods to understand the physics and chemistry of materials formation.
