A special topic issue of Pure
and Applied Chemistry, Vol. 74, No. 9, 2002. IUPAC, 2002.
Suggestions, comments, questions regarding
IUPAC activities on the subject of Materials Chemistry
should be addressed to Prof. John Corish <[email protected]>,
chairman of the Subcommittee on Materials Chemistry.
A focus of frontline interdisciplinary
research today is the development of the conceptual framework
and the experimental background of the science of nanostructured
materials and the perspectives of its technological applications.
The subjects of nanoscience and nanotechnology pertains to
the synthesis, characterization, exploration, interrogation,
exploitation, and utilization of nanostructured materials,
which are characterized by at least one dimension in the nanometer
domain. Such nanostructured systems constitute a bridge between
single molecules and infinite bulk systems. Individual nanostructures
involve clusters, nanoparticles, nanocrystals, quantum dots,
nanowires, and nanotubes, while collections of nanostructures
involve arrays, assemblies, and superlattices of individual
The implications of quantum
size and shape effects on the energetics, nuclear-electronic
level structure, electric-optical response, and dynamics,
reveal new unique physical phenomena that qualitatively differ
from those of the bulk matter and provide avenues for the
control of the function of nanostructures.
This special topic issue of
Pure and Applied Chemistry includes reviews and research
papers based on lectures presented at the second Workshop
on Advanced Materials: Nanostructured Materials (WAM II),
held from 1316 February 2002 in Bangalore, India (See
Conference report, CI May 2002, p.22). This PAC
issue was coordinated by Professor J. Bull, IUPAC Special
Topics Editor and Professor G.U. Kulkarni, chairman of the
Local Organizing Committee. The papers addressed recent developments
in the broad, interdisciplinary research field of nanostructured
materials and are organized under the following categories:
synthesis and characterization, spectroscopic and other physical
properties, and applications of nanostructured materials.
Perspectives and directions
are given in the introduction authored by C. N. R. Rao and
Joshua Jortner. That paper highlights some significant aspects
of the characterization, interrogation, and response of nanostructures,
in conjunction with theoretical modeling of the unique structure,
dynamics, and function of quantum structures and their assemblies.
