Introduction

Julia Weertman of Northwestern University opened the workshop by welcoming the participants on behalf of her co-chair, T.S.Sudarshan of Materials Modification Inc., National Materials Advisory Board (NMAB) project director Julius Chang, and the NMAB staff. Before describing the goals and hoped-for outcomes of the workshop, she briefly went through the many materials-related terms that involve the prefix “nano.” Most of these “nano-X” terms—e.g., nanoscale, nanophase, nanolayer, nanomaterial, nanostructure—indicate that at least one feature (X) has a length scale less than ~100 nm. Nanoscience is the science of the nano-Xs, while nanotechnology as used in the present context refers to the production and use of the nano-Xs.

Professor Weertman listed the topics and goals to be addressed:

  • Synthesis and assembly of nanomaterial building blocks;

  • Characterization of nanomaterials;

  • Examples of structural nanomaterials currently in use;

  • Potential applications of nanomaterials;

  • Gaps in understanding of synthesis, assembly, chemical, and physical characterization and the need for an interdisciplinary approach; and

  • Identification of the “showstoppers”—major barriers to utilization of nanomaterials.

The workshop then moved on to the first session, on synthesis, assembly, and processing.
