This is the report of a DOE-sponsored workshop organized to discuss the status of our understanding of
charge-transfer processes on the nanoscale and to identify research and other needs for progress in nanoscience
and nanotechnology. The current status of basic electron-transfer research, both theoretical and experimental,
is addressed, with emphasis on the distance-dependent measurements, and we have attempted to integrate
terminology and notation of solution electron-transfer kinetics with that of conductance analysis. The interface
between molecules or nanoparticles and bulk metals is examined, and new research tools that advance
description and understanding of the interface are presented. The present state-of-the-art in molecular electronics
efforts is summarized along with future research needs. Finally, novel strategies that exploit nanoscale
architectures are presented for enhancing the efficiences of energy conversion based on photochemistry,
catalysis, and electrocatalysis principles.
