Recently, the study and development of nanomaterials, a field which is quickly becoming one of the most promising fields of science and technology today, and the development in electron optics, detectors, stage design and fabrication, and recording media has brought an exciting resurgence of interest in TEM.  The goal of this symposium is to bring together a wide variety of researchers with interests in the science, engineering and technological applications to discuss the use of TEM/STEM and SEM techniques on the characterization and modification of properties of materials. Abstracts are solicited in, but not limited to, the following areas involving the use of TEM/STEM and SEM.
