to the Fundamental and Applied Catalysis Series Catalysis is
important academically and industrially. It plays an essential role
in the manufacture of a wide range of products, from gasoline and
plastics to fertilizers and herbicides, which would otherwise be
unobtainable or prohibitively expensive. There are few chemical-or
oil-based material items in modem society that do not depend in
some way on a catalytic stage in their manufacture. Apart from manu
facturing processes, catalysis is finding other important and
ever-increasing uses; for example, successful applications of
catalysis in the control of pollution and its use in environmental
control are certain to increase in the future. The commercial
importance of catalysis and the diverse intellectual challenges of
catalytic phenomena have stimulated study by a broad spectrum of
scientists, including chemists, physicists, chemical engineers, and
material scientists. Increas ing research activity over the years
has brought deeper levels of understanding, and these have been
associated with a continually growing amount of published material.
As recently as sixty years ago, Rideal and Taylor could still treat
the subject comprehensively in a single volume, but by the 1950s
Emmett required six volumes, and no conventional multivolume text
could now cover the whole of catalysis in any depth. In view of
this situation, we felt there was a need for a collection of
monographs, each one of which would deal at an advanced level with
a selected topic, so as to build a catalysis reference library.
During the past fifteen years commercial interest in compounds
containing carbon fluorine bonds has burgeoned beyond all
expectations, mainly owing to business opportunities arising from
work on biologically active fluoroorganics-particularly
agrochemicals, the relentless search for new markets for
fluoropolymers and fluoro carbon fluids, developments in the field
of medical diagnostics, and the drive to find replacements for
ozone-depleting CFCs and Halon fire-extinguishing agents. Judging
the situation to warrant the publication of a comprehensive
collection of up-to-date reviews dealing with commercial
organofluorine compounds within a single volume of manageable size
(and hence reasonable cost), we were delighted to be invited by
Plenum Publishing Corporation to produce a suitable book. In order
to provide an authentic and wide-ranging account of current
commercial applications of fluoroorganic materials, it clearly was
necessary to assemble a sizeable team of knowledgeable contributing
authors selected almost entirely from industry. Through their
efforts we have been able to produce an almost complete coverage of
the modem organofluorochemicals business in a manner designed to
attract a reader ship ranging from experts in the field, through
chemists and technologists currently unaware of the extent of
industrial involvement with fluoroorganics, to students of applied
chemistry. Promised chapters dedicated to perfluoroolefin oxides
and 18F labeling of radiopharmaceuticals failed to materialize.
This is somewhat unfortunate in view of our aim to achieve
comprehensive coverage of the subject.

Some have predicted that the coming several decades will be the
decades of "biotechnology," wherein cancer, birth defects, life
span increases, cosmetics, biodegradation, oil spills and
exploration, solid waste disposal, and almost every aspect of our
material life will be affected by this new area of science. There
will also be an extension of emphasis on giant molecules: DNA,
enzymes, polysaccharides, lignins, proteins, hemoglobin, and many
others. Biotechnology has been defined in various ways. In one
sense, this field is older than human history and references to the
human use of biotechnology-derived materials can be found in the
oldest human writings, such as the Bible. In this book,
biotechnology refers to the direct usage of naturally occurring
materials or their uses as a feedstock, including the associated
biological activities and applications of these materials.
Bioactive polymers, on the other hand, are polymers which exert
some type of activity on living organisms. These polymers are used
in agriculture, controlled release systems, medicine and many other
areas. The papers in this book describe polymers which essentially
combine features of biotechnology and bioactivity.
Reviewing over 100 chemical and physical methods for analysis of
polymers, Manual of Plastics Analysis is so detailed and
comprehensive that chemists can apply the methods - many previously
unpublished - directly from the book. A genuine laboratory manual,
the volume supplies prodigious amounts of up-to-date information on
all types of polymers, polymer additives, volatiles, adventitious
impurities, monomers, metals, and pigments. Extremely well-suited
for classroom teaching, research, or industrial applications, the
book contains numerous tables and figures, as well as many chemical
equations illustrating its analytical techniques.
Nanostructures refer to materials that have relevant dimensions on
the nanometer length scales and reside in the mesoscopic regime
between isolated atoms and molecules in bulk matter. These
materials have unique physical properties that are distinctly
different from bulk materials. Self-Assembled Nanostructures
provides systematic coverage of basic nanomaterials science
including materials assembly and synthesis, characterization, and
application. Suitable for both beginners and experts, it balances
the chemistry aspects of nanomaterials with physical principles. It
also highlights nanomaterial-based architectures including
assembled or self-assembled systems. Filled with in-depth
discussion of important applications of nano-architectures as well
as potential applications ranging from physical to chemical and
biological systems, Self-Assembled Nanostructures is the essential
reference or text for scientists involved with nanostructures.
In this reference, the author thoroughly reviews the current state
of condensed phosphate chemistry. A unique feature of this volume
is an examination of the recent developments in X-ray structural
techniques, reporting on fundamental results obtained through their
use. Enhanced by comprehensive tables reporting crystal data,
chapters identify and characterize more than 2,000 compounds.
Additional features include a concise survey of the historical
development of condensed phosphate chemistry; the presently
accepted classification system; a review of each family of
condensed phosphates and much more.
This book was planned and written with one central goal in mind: to
demonstrate that statistical thermodynamics can be used
successfully by a broad group of scientists, ranging from chemists
through biochemists to biologists, who are not and do not intend to
become specialists in statistical thermodynamics. The book is
addressed mainly to gradu ate students and research scientists
interested in designing experiments the results of which may be
interpreted at the molecular level, or in interpreting such
experimental results. It is not addressed to those who intend to
practice statistical thermodynamics per se. With this goal in mind,
I have expended a great deal of effort to make the book clear,
readable, and, I hope, enjoyable. This does not necessarily mean
that the book as a whole is easy to read. The first four chapters
are very detailed. The last four become progressively more
difficult to read, for several reasons. First, presuming that the
reader has already acquired familiarity with the methods and
arguments presented in the first part, I felt that similar
arguments could be skipped later on, leaving the details to be
filled in by the reader. Second, the systems themselves become
progressively more com plicated as we proceed toward the last
chapter.
For several years, I have been responsible for organizing and
teaching in the fall a short course on "Fundamentals of Adhesion:
Theory, Practice, and Applications" at the State University of New
York at New Paltz. Every spring I would try to assemble the most
pertinent subjects and line up several capable lecturers for the
course. However, there has always been one thing missing-an
authoritative book that covers most aspects of adhesion and
adhesive bonding. Such a book would be used by the participants as
a main reference throughout the course and kept as a sourcebook
after the course had been completed. On the other hand, this book
could not be one of those "All you want to know about" volumes,
simply because adhesion is an interdisciplinary and ever-growing
field. For the same reason, it would be very difficult for a single
individual, especially me, to undertake the task of writing such a
book. Thus, I relied on the principle that one leaves the truly
monumental jobs to experts, and I finally succeeded in asking
several leading scientists in the field of adhesion to write
separate chapters for this collection. Some chapters emphasize
theoretical concepts and others experimental techniques. In the
humble beginning, we planned to include only twelve chapters.
However, we soon realized that such a plan would leave too much
ground uncovered, and we resolved to increase the coverage. After
the book had evolved into thirty chapters, we started to feel that
perhaps our mission had been accomplished.
The 1982 summer school on nuclear physics, organized by the Nuclear
Physics Division of the Netherlands' Physical Society, was the
fifth in a series that started in 1963. The number of students
attending has always been about one hundred, coming from about
thirty countries. The theme of this year's school was symmetry in
nuclear physics. This book covers the material presented by the
enthusi astic speakers, who were invited to lecture on this
subject. We think they have succeeded in presenting us with clear
and thorough introductory talks at graduate or higher level. The
time schedule of the school and the location allowed the
participants to make many informal contacts during many social
activities, ranging from billiards to surf board sailing. We hope
and expect that the combination of a relaxed atmosphere during part
of the time and hard work during most of the time, has furthered
the interest in, and understanding of, nuclear physics. The
organization of the summer school was made possible by substantial
support from the Scientific Affairs Division of the North Atlantic
Treaty Organization, the Netherlands' Ministry of Education and
Science, the Foundation Physica and the Nether lands' Physical
Society."
Over the last several years, the field of materials science has
witnessed an explosion of new, advanced materials. They encompass
many uses and include superconductors, alloys, glasses, and
catalysts. Not only are there quite a number of new enhies into
these generic classes of materials, but the materials themselves
represent a wide array of physical forms as well. Bulk materials,
for example, are being synthesized and applica tions found for
them, while still other materials are being synthesized as thin
films for yet still more new (and in some cases, as yet unknown)
applications. The field continues to expand with (thankfully ) no
end in sight as to the number of new possibilities. As work
progresses in this area, there is an ever increasing demand for
knowing not only what material is formed as an end product but also
details of the route by which it is made. The knowledge of reaction
mechanisms in their synthesis many times allows a researcher to
tailor a preparative scheme to either arrive at the final product
in a purer state or with a better yield. Also, a good fundamental
experimental knowledge of impuri ties present in the final material
helps the investigator get more insight into making it."

Fiberglass and Glass Technology: Energy-Friendly Compositions and
Applications provides a detailed overview of fiber, float and
container glass technology with special emphasis on energy- and
environmentally-friendly compositions, applications and
manufacturing practices which have recently become available and
continue to emerge. Energy-friendly compositions are variants of
incumbent fiberglass and glass compositions that are obtained by
the reformulation of incumbent compositions to reduce the viscosity
and thereby the energy demand. Environmentally-friendly
compositions are variants of incumbent fiber, float and container
glass compositions that are obtained by the reformulation of
incumbent compositions to reduce environmentally harmful emissions
from their melts. Energy- and environmentally-friendly compositions
are expected to become a key factor in the future for the
fiberglass and glass industries. This book consists of two
complementary sections: continuous glass fiber technology and
soda-lime-silica glass technology. Important topics covered
include: o Commercial and experimental compositions and products o
Design of energy- and environmentally-friendly compositions o
Emerging glass melting technologies including plasma melting o
Fiberglass composite design and engineering o Emerging fiberglass
applications and markets Fiberglass and Glass Technology:
Energy-Friendly Compositions and Applications is written for
researchers and engineers seeking a modern understanding of glass
technology and the development of future products that are more
energy- and environmentally-friendly than current products.
This volume chronicles the proceedings of the Symposium on
Metallized Plastics: Fundamental and Applied Aspects held under the
auspices of the Dielectrics and Insulation Division of the
Electrochemical Society in Chicago, October 10-12, 1988. This was
the premier symposium on this topic and if the comments from the
attendees are any barometer of the success of a symposium then it
was a grand success. Concomitantly, it has been decided to hold it
on a regular basis (at intervals of 18 months) and the second event
in this series is planned as a part of the Electrochemical Society
meeting in Montreal, Canada, May 6-10, 1990. Metallized plastics
find a legion of applications ranging from mundane to very
sophisticated. A complete catalog of the various technological
applications of metallized plastics will be prohibitively long, so
here some eclectic examples should suffice to show why there is
such high tempo of R&D activity in the arena of metallized
plastics, and all signals indicate that this high tempo will
continue unabated. For example, polymeric films are metallized for
packaging (food and other products) purposes, and the applications
of metallized plastics in the automotive industry are quite
obvious. In the field of microelectronics and computer technology,
insulators are metallized for interconnection and other functional
purposes. Also plastics are metallized to provide electromagnetic
shielding.
This book documents the proceedings of the symposium, "Mineral
Scale Formation and Inhibition," held at the American Chemical
Society Annual Meeting August 21 to 26, 1994, in Washington, D. C.
The symposium, sponsored by the Division of Colloid and Surface
Chemistry, was held in honor of Professor George H. Nancollas for
his pioneering work in the field of crystal growth from solution. A
total of 30 papers were presented by a wide spectrum of scientists.
This book also includes papers that were not presented but were in
the symposium program. The separation of a solid by crystallization
is one of the oldest and perhaps the most frequently used
operations in chemistry. Because of its widespread applicability,
in recent years there has been considerable interest exhibited by
academic and industrial scientists in understanding the mechanisms
of crystallization of sparingly soluble salts. The salt systems of
great interest in industrial water treatment area (i. e., cooling
and boiler) include carbon ates, sulfates, phosphates, and
phosphonates of alkaline earth metals. Although not as common as
calcium carbonate and calcium sulfate, barium and strontium
sulfates have long plagued oil field and gas production operations.
The build-up of these sparingly soluble salts on equipment surfaces
results in lower heat transfer efficiency, increased corrosion
rates, increased pumping costs, etc. In the laundry application,
insoluble calcium carbonate tends to accumulate on washed fabrics
and washing equipment parts, resulting in undesirable
fabric-encrustation or scaling."
Stability constants are fundamental to understanding the behavior
of metal ions in aqueous solution. Such understanding is important
in a wide variety of areas, such as metal ions in biology,
biomedical applications, metal ions in the environment, extraction
metallurgy, food chemistry, and metal ions in many industrial
processes. In spite of this importance, it appears that many
inorganic chemists have lost an appreciation for the importance of
stability constants, and the thermodynamic aspects of complex
formation, with attention focused over the last thirty years on
newer areas, such as organometallic chemistry. This book is an
attempt to show the richness of chemistry that can be revealed by
stability constants, when measured as part of an overall strategy
aimed at understanding the complexing properties of a particular
ligand or metal ion. Thus, for example, there are numerous crystal
structures of the Li+ ion with crown ethers. What do these indicate
to us about the chemistry of Li+ with crown ethers? In fact, most
of these crystal structures are in a sense misleading, in that the
Li+ ion forms no complexes, or at best very weak complexes, with
familiar crown ethers such as l2-crown-4, in any known solvent.
Thus, without the stability constants, our understanding of the
chemistry of a metal ion with any particular ligand must be
regarded as incomplete. In this book we attempt to show how
stability constants can reveal factors in ligand design which could
not readily be deduced from any other physical technique.
Iron Acquisition by the Genus Mycobacterium summarizes the early
evidence for the necessity of iron in mycobacteria and the
discovery of the mycobacterial siderophores mycobactin,
carboxymycobactin, and exochelin. The structural characterization
of the mycobacterial siderophores is described. The genes so far
identified as essential for iron acquisition and maintenance of an
infection by pathogenic mycobacteria are discussed. The potential
role of siderocalin in iron gathering by M. tuberculosis is
featured. Because new drugs for M. tuberculosis are needed, this
brief also emphasizes the design of antibiotics that interfere with
siderophore biosynthesis and the use of siderophore analogs and/or
conjugates.

Science is not a mere collection of facts. It is the correlation of
facts, the interpretative synthesis of the available knowledge and
its application that excite the imagination of a scientist. Even in
these days of modern technology, the need for quick and accurate
dissemination of new information and current concepts still exists.
Conferences and Symposia offer one direct method of communication.
The Summer Schools are another approach. The success of a Summer
School is mainly due to that human factor and under standing that
goes with it and allows for extensive and often time-unrestricted
discussions. During the course of the past 20 years, one of the
most in tensively studied groups of elements in the Periodic Table
is the Lanthanides. In this period, we have increased our knowledge
on these once exotic elements, which were once considered to be a
part of a lean and hungry industry, many-fold due to the involve
ment of scientists from various disciplines. The purpose of our
Summer School was to bring a group of ex perts and participants
together for the exchange of ideas and in formation in an informal
setting and to promote interdisciplinary interactions. Out of many
conceivable topics, we selected the following five as the main
basis to broaden our knowledge and understanding I) Systematics 2)
Structure 3) Electronic and Magnetic Proper ties 4) Spectroscopic
Properties and 5) Lanthanide Geochemistry."
Originally published in 2001, this book describes in detail various
experimental techniques used in the study of liquid crystals. It
will be indispensable for established workers in the field as well
as students embarking on liquid crystal research. Each chapter in
the book is dedicated to an important experimental technique used
in the study and characterisation of liquid crystalline systems.
Use of these techniques on liquid crystals requires modifications
of traditional experiments, special sample handling and a fresh a
approach to data analysis. In addition, general routes used to
synthesise liquid crystals and tools to characterise liquid crystal
phases are described. Attempts are also made to show structure
property relationships for well known systems. This book will be of
particular interest to graduate students in physics and chemistry
as well as established researchers in the fields of liquid crystals
and soft condensed matter.
The phenomenon of catalysis is found in many homogeneous and
heterogeneous systems undergoing chemical change, where it effects
the rates of approach to the equilibrium state in processes as
diverse as those found in the stars, the earth's mantle, living
organisms, and the various chemistries utilized by industry. The
economies and the living standards of both developed and developing
countries depend to varying degrees upon the efficacy of their
chemical industries. Con sequently, this century has seen a wide
exploration and expansion of catalytic chemistry together with an
intensive investigation of specific, essential processes like those
contributing to life-supporting agricultures. Prime among the
latter must surely be the "fixation" of atmospheric nitrogen by
catalytic hydrogenation to anhydrous ammonia, still the preferred
synthetic precursor of the nitrogenous components of fertilizers.
In each decade contemporary concepts and techniques have been used
to further the understanding, as yet incomplete, of the catalyst,
the adsorbates, the surface reactions, and the technology of
large-scale operation. The contributors to the present volume
review the state of the art, the science, and the technology; they
reveal existing lacunae, and suggest ways forward. Around the turn
of the century, Sabatier's school was extending the descriptive
catalytic chemistry of hydrogenation by metals to include almost
all types of multiple bond. The triple bond of dinitrogen, which
continued to be more resistant than the somewhat similar bonds in
carbon monoxide and ethyne, defied their efforts.
The physical properties of water and steam have been the subject of
lhorough investigation for a long time. It can, on the one hand, be
due to the important role of this substance in the processes that
take place in nature and, on the .other hand, due to its wide
industrial use. Steam is the most important working substance used
in conventional and nuc lear power plants, in chemical engineering
and other fields of industry. The variety of practical use of water
and steam generates a need for knowing their thermodynamic,
transport, electrical, and other properties over a .very wide range
of temperatures and pressures. International Conferences on the
Properties of Steam, which have taken place since 1929, have the
aim to promote wide exchange of the results of theoretical and
experimental studies into the properties of ordinary and heavy
water in a11 phase states. In the course of last decade f.he
investigation oC physical and chemical properties of concentrated
and dilute aqueous solutions that are of interest in the first
place from the point of view of power play an important part in
these studies."
Metal-Oxygen Clusters is the first book, providing an overview of
the surface chemistry and catalytic properties of heteropoly
oxometalates. After a brief look at the early knowledge of
heteropoly oxometalates, the book discusses the synthesis,
characterization, structure, bulk properties and stability of these
materials. The remainder and the largest portion of the book
explores the properties of these solids as catalysts in
acid-catalyzed and oxidation processes in supported or unsupported
forms. The book provides an up-to-date review of the methods for
synthesizing heteropoly oxometalates of Keggin structure,
techniques from spectroscopic through electrochemical to elemental
analysis for their characterization and the current information on
their structure, bulk properties and their stabilities at high
temperatures and under acid and alkaline conditions. The book
discusses the materials employed as supports for the title solid
and the results of the examination of the supported materials.
Methods for the identification of the nature and source of the two
catalytic functions, the acidic and oxidative properties, of the
heteropoly oxometalates are reviewed and discussed. The use of both
the supported and unsupported heteropoly oxometalates as catalysts
in acidity-requisite processes ranging from methanol conversion to
hydrocarbons to ring-expansion and contraction processes and in
oxidation processes from methane cyclohexane are described and
related to the aforementioned properties.
