This series of books, which is published at the rate of about one per
year, addresses fundamental problems in materials science. The contents
cover a broad range of topics from small clusters of atoms to
engineering materials and involve chemistry, physics, and engineering,
with length scales ranging from Ångstromsup to millimeters. The emphasis
is on basic science rather than on applications. Each book focuses on a
single area ofcurrent interest and brings together leading experts to
give an up-to-date discussion of their work and the work ofothers. Each
article contains enough references that the interested reader can
accesstherelevant literature. Thanks aregiven to the Center
forFundamental Materials Research atMichigan State University
forsupportingthis series. M.F. Thorpe, Series Editor E-mail:

book records selected papers given at an interdisciplinary Symposium on
Access in Nanoporous Materials held in Lansing, Michigan, on June 7-9,
1995. Broad interest in the synthesis of ordered materials with pore
sizes in the 1.0-10 nm range was clearly manifested in the 64 invited
and contributed papers presented by workers in the formal fields of
chemistry, physics, and engineering. The intent of the symposium was to
bring together a small number ofleading researchers within complementary
disciplines to share in the diversity of approaches to nanoporous
materials synthesis and characterization.
