MMMS05 Conference

Conference presentation

As part of its outreach activities, the Center for Microanalysis of Materials and Frederick Seitz Materials Research Laboratory has hosted and will continue to host, a variety of National/Regional conferences with topics of interest to the materials research community. Past conferences have had a strong emphasisis on the characterization of materials at the nanoscale.

MMMS05: Dynamics of Materials Revealed by Electron Microscopy

June 9-10, 2005

We stand at the beginning of a new era for electron microscopy; the limits imposed by aberrations are being shattered allowing the development of an entirely new class of electron microscopes that will decouple the link between instrument resolution and the size of the gap between the objective lens poles. These new instruments will allow high spatial, temporal and spectral resolution to coexist with macroscopic experimental modules permitting the design of unique in-situ experiments to study structure/property, stimuli/response, and related dynamic processes at or near atomic resolution.

There has been much work in the electron microscopy community to allow direct imaging and analysis of real world processes in their native environment. Major advances in understanding have resulted from the application of these in-situ techniques in fields as diverse as surface physics, strength of materials, epitaxial growth, and catalytic reactions to name a few. These outstanding achievements were performed even within the limits imposed by spherical aberration and these and other fields stand to benefit enormously from the development of an in-situ aberration corrected microscope.

The organizers of this workshop seek to bring together a broad coalition of scientists, both among and outside the electron microscopy community, to discuss the requirements of the next generation of in-situ materials science tools. This discussion will be facilitated by highlighting past achievements in the field, by reviewing the current state and expected future of aberration corrected electron optics, and by discussing current experimental results that use novel methods to investigate dynamic processes. The main challenge is to identify specific areas of materials research where the capabilities of the proposed instruments will be indispensable for achieving scientific breakthroughs. By focusing on the needs and requirements of the scientific community, the necessity to build and fund this exciting new class of materials science laboratories will be shown to be crucial.
