Volume 44 of Reviews in Mineralogy and Geochemistry contains descriptions of the inorganic and
biological processes by which nanoparticles form information about the distribution of
nanoparticles in the atmosphere aqueous environments and soils discussion of the impact of
size on nanoparticle structure thermodynamics and reaction kinetics consideration of the
nature of the smallest nanoparticles and molecular clusters pathways for crystal growth and
colloid formation analysis of the size-dependence of phase stability and magnetic properties
and descriptions of methods for the study of nanoparticles. These questions are explored
through both theoretical and experimental approaches.This volume was prepared in conjunction
with a short course Nanoparticles in the Environment and Technology convened on the campus of
the University of California Davis CA on December 8 and 9 2001.
