This thesis focuses on porous monolithic materials that are not in
the forms of particles, fibers, or films. In particular, the
synthetic strategy of porous monolithic materials via the sol-gel
method accompanied by phase separation, which is characterized as
the non-templating method for tailoring well-defined macropores, is
described from the basics to actual synthesis. Porous materials are
attracting more and more attention in various fields such as
electronics, energy storage, catalysis, sensing, adsorbents,
biomedical science, and separation science. To date, many efforts
have been made to synthesize porous materials in various chemical
compositions-organics, inorganics including metals, glasses and
ceramics, and organic-inorganic hybrids. Also demonstrated in this
thesis are the potential applications of synthesized porous
monolithic materials to separation media as well as to electrodes
for electric double-layer capacitors (EDLCs) and Li-ion batteries
(LIBs). This work is ideal for graduate students in materials
science and is also useful to engineers or scientists seeking basic
knowledge of porous monolithic materials.
The art of chemistry is to thoroughly understand the properties of
molecular compounds and materials and to be able to prepare novel
compounds with p- dicted and desirable properties. The basis for
progress is to fully appreciate and fundamentally understand the
intimate relation between structure and function. The thermodynamic
properties (stability, selectivity, redox potential), reactivities
(bond breaking and formation, catalysis, electron transfer) and
electronic properties (spectroscopy, magnetism) depend on the
structure of a compound. Nevertheless, the discovery of novel
molecular compounds and materials with exciting prop- ties is often
and to a large extent based on serendipity. For compounds with
novel and exciting properties, a thorough analysis of experimental
data - state-of-the-art spectroscopy, magnetism, thermodynamic
properties and/or detailed mechanistic information - combined with
sophisticated electronic structure calculations is p- formed to
interpret the results and fully understand the structure,
properties and their interrelation. From these analyses, new models
and theories may emerge, and this has led to the development of ef
cient models for the design and interpre- tion of new materials and
important new experiments. The chapters in this book therefore
describe various fundamental aspects of structures, dynamics and
physics of molecules and materials. The approaches, data and models
discussed include new theoretical developments, computational
studies and experimental work from molecular chemistry to biology
and materials science.
Inorganic Bioelectrochemistry provides a thorough overview of the
state of the art in this crucial area of research. In addition, the
book helps readers understand where the field is heading and what
new developments are on the horizon. Eight chapters written by
leading international experts cover crucial topics such as electron
and proton transfer in metalloprotein systems, electrochemistry and
electrocatalysis of redox enzymes, and electrochemistry of
DNA-based molecules.
This book presents critical reviews of the present position and
future trends in modern chemical research concerned with chemical
structure and bonding. It contains short and concise reports, each
written by the world's renowned experts. Still valid and useful
after 5 or 10 years, more information as well as the electronic

In the future, many modern materials will be increasingly based on
the assembly of preformed molecular entities. Their structural
characteristics and functional prop- ties will be programmed at the
molecular level and their formation as a completed entity will be
achieved by self-assembly processes. This in essence is a bottom-up
approach and its success will require a deep understanding not only
of the chemistry of intermolecular interactions and associations
but also of self-assembly processes in the condensed phase. Among
various interesting innovations brought about by the development of
supramolecular chemistry, supramolecular synthesis is a part-
ularly powerful approach for the design and generation of molecular
architectures displaying both structural and functional complexity.
The combination of mol- ular synthesis (which allows chemists to
design and prepare extremely sophis- cated biotic and abiotic
molecules through the interconnection of atoms or group of atoms by
strong covalent bonds) and supramolecular synthesis (which orch-
trates the association of molecules by recognition processes
through the use of weak and reversible interactions) opens up
endless structural and functional possibilities. Following the
perceptive observation by Dunitz that "A crystal is, in a sense,
the supramolecule par excellence", molecular crystals may be seen
as in?nite periodic architectures resulting from the
interconnection of building blocks or tectons ca- ble of
self-assembling through speci?c recognising events.
Involved as it is with 95% of the periodic table, inorganic
chemistry is one of the foundational subjects of scientific study.
Inorganic catalysts are used in crucial industrial processes and
the field, to a significant extent, also forms the basis of
nanotechnology. Unfortunately, the subject is not a popular one for
undergraduates. This book aims to take a step to change this state
of affairs by presenting a mechanistic, logical introduction to the
subject.
Organic teaching places heavy emphasis on reaction mechanisms -
"arrow-pushing" - and the authors of this book have found that a
mechanistic approach works just as well for elementary inorganic
chemistry. As opposed to listening to formal lectures or learning
the material by heart, by teaching students to recognize common
inorganic species as electrophiles and nucleophiles, coupled with
organic-style arrow-pushing, this book serves as a gentle and
stimulating introduction to inorganic chemistry, providing students
with the knowledge and opportunity to solve inorganic reaction
mechanisms.- The first book to apply the arrow-pushing method to
inorganic chemistry teaching- With the reaction mechanisms approach
("arrow-pushing"), students will no longer have to rely on
memorization as a device for learning this subject, but will
instead have a logical foundation for this area of study- Teaches
students to recognize common inorganic species as electrophiles and
nucleophiles, coupled with organic-style arrow-pushing- Provides a
degree of integration with what students learn in organic
chemistry, facilitating learning of this subject- Serves as an
invaluable companion to any introductory inorganic chemistry

For the practical application of thermochemistry to the development
and control of tech nical processes, the data for as many
substances as possible are needed in conjunction with rapid and
simple methods of calculating equilibrium constants, heat balances
and the EMF of galvanic cells. For these three types of calculation
the following three ther modynamic functions are suitable: The
Planck function, the enthalpy and the Gibbs free energy, which are
here defined and tabulated as unambigous functions of temperature
for pure substances. The first edition of the tables was published
in 1973 under the title "Thermochemical Properties of Inorganic
Substances". The present supplementary volume contains the data and
functions for a further 800 inorganic substances. In addition, the
data for about 250 substances from the first volume have been
up-dated. These usually small corrections produce better
consistency with the data from more recent publications. The
comments of users and reviewers of the first volume have largely
been concerned with the difference between the present
thermodynamic functions and the system used in the JANAF tables,
the somewhat unconventional handling of heat balances adopted here,
the notation of cell reactions, the description of
non-stoichiometric phases and the accuracy of the tabulated data.
To answer these questions and criticims the theore tical concepts
and the practical use of the tables are dealt with in more detail
in the introduction, following the recommendation of some
reviewers.

In his thesis, Sohail Shahzad carefully investigates carbon
nucleophiles in selenocyclisations, as well as reaction protocols
for performing such reactions catalytically. After a comprehensive
introduction to the element selenium, the author goes on to report
the synthesis of several substrates for carbocyclisation reactions
and the use of selenium reagents for the preparation of
dihydronaphthalenes. Further chapters detail electrophilic
selenium-mediated reactions, and novel strategies using selenium
catalysts together with stoichiometric amounts of hypervalent
iodine reagents as oxidants to convert stilbene carbosylic acids
into the corresponding isocoumarins. This thesis outlines some
excellent new synthetic routes which will be useful tools for
synthetic organic chemistry in the future.
Chemical sensors are in high demand for applications as varied as
water pollution detection, medical diagnostics, and battlefield air
analysis. Designing the next generation of sensors requires an
interdisciplinary approach. The book provides a critical analysis
of new opportunities in sensor materials research that have been
opened up with the use of combinatorial and high-throughput
technologies, with emphasis on experimental techniques. For a view
of component selection with a more computational perspective,
readers may refer to the complementary volume of Integrated
Analytical Systems edited by M. Ryan et al., entitled
"Computational Methods for Sensor Material Selection".
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.
The series Structure and Bonding publishes critical reviews on
topics of research concerned with chemical structure and bonding.
The scope of the series spans the entire Periodic Table and
addresses structure and bonding issues associated with all of the
elements. It also focuses attention on new and developing areas of
modern structural and theoretical chemistry such as nanostructures,
molecular electronics, designed molecular solids, surfaces, metal
clusters and supramolecular structures. Physical and spectroscopic
techniques used to determine, examine and model structures fall
within the purview of Structure and Bonding to the extent that the
focus is on the scientific results obtained and not on specialist
information concerning the techniques themselves. Issues associated
with the development of bonding models and generalizations that
illuminate the reactivity pathways and rates of chemical processes
are also relevant. The individual volumes in the series are
thematic. The goal of each volume is to give the reader, whether at
a university or in industry, a comprehensive overview of an area
where new insights are emerging that are of interest to a larger
scientific audience. Thus each review within the volume critically
surveys one aspect of that topic and places it within the context
of the volume as a whole. The most significant developments of the
last 5 to 10 years should be presented using selected examples to
illustrate the principles discussed. A description of the physical
basis of the experimental techniques that have been used to provide
the primary data may also be appropriate, if it has not been
covered in detail elsewhere. The coverage need not be exhaustive in
data, but should rather be conceptual, concentrating on the new
principles being developed that will allow the reader, who is not a
specialist in the area covered, to understand the data presented.
Discussion of possible future research directions in the area is
welcomed.
Organometallic Ion Chemistry features eight chapters, written by
acknowledged authorities, covering the gas-phase chemistry of
organometallic ions. Topics covered include: periodic trends in
gas-phase thermochemistry of transition metal-ligand systems; ab
initio calculations to determine electronic structure, geometric
structure, and thermochemistry of metal-containing systems;
electronic state effects on metal ion reactivity; organometallic
ion photochemistry; applications of gas-phase electron transfer
equilibria in organometallic redox thermochemistry. Also included
are state of the art mass spectrometric instrumentation used in
such studies. Finally, the book features - for the first time in
one place - a comprehensive list (containing over 1500 entries) of
metal ion-ligand bond energies, obtained from theory and
experiment. An invaluable reference source for ion chemists,
organometallic chemists and surface chemists, at both expert and
graduate student levels.
The contributors to this volume study macroscopic flow properties
and molecular mobility in complex liquids with high internal
mobility and a highly anisotropic molecular shape. Particular
attention is paid to the wide variety of experimental approaches,
in theory as well as in computer simulation of these difficult but
very important problems. The contributions are of interest to
researchers in physics as well as in engineering and chemistry.
Dr. Alan Williams has acquired a considerable experience in work
with transition metal complexes at the Universities of Cambridge
and Geneva. In this book he has tried to avoid the variety of
ephemeral and often contradictory rationalisations encountered in
this field, and has made a careful comparison of modern opinions
about chemical bond ing. In my opinion this effort is fruitful for
all students and active scientists in the field of inorganic
chemistry. The distant relations to group theory, atomic
spectroscopy and epistemology are brought into daylight when Dr.
Williams critically and pedagogic ally compares quantum chemical
models such as molecular orbital theory, the more specific L. C. A.
O. description and related "ligand field" theory, the valence bond
treat ment (which has conserved great utility in antiferromagnetic
systems with long inter nuclear distances), and discusses
interesting, but not too well-defined concepts such as
electronegativity (also derived from electron transfer spectra),
hybridisation, and oxid ation numbers. The interdisciplinary
approach of the book shows up in the careful consideration given to
many experimental techniques such as vibrational (infra-red and
Raman), elec tronic (visible and ultraviolet), Mossbauer, magnetic
resonance, and photoelectron spectra, with data for gaseous and
solid samples as well as selected facts about solution chemistry.
The book could not have been written a few years ago, and is likely
to re main a highly informative survey of modern inorganic
chemistry and chemical physicS. Geneva, January 1979 C. K.
In this comprehensive text a systematic numerical and analytical
treatment of the procedures for reducing complicated systems to a
simplified reaction mechanism is presented. The results of applying
the reduced reaction mechanism to a one-dimensional laminar flame
are discussed. A set of premixed and non-premixed methane-air
flames with simplified transport and skeletal chemistry are
employed as test problems that are used later on to evaluate the
results and assumptions in reduced reaction networks. The first
four chapters form a short tutorial on the procedures used in
formulating the test problems and in reducing reaction mechanisms
by applying steady-state and partial-equilibrium approximations.
The final six chapters discuss various aspects of the reduced
chemistry problem for premixed and nonpremixed combustion.
Our understanding of the basic processes of crystal growth has
meanwhile reached the level of maturity at least in the
phenomenological concepts. This concerns for example the growth of
pure crystals from a low-density nutrient phase like vapor or
dilute solution with various aspects of pattern formation like
spiral and layer growth, facetting and roughening, and the
stability of smooth macroscopic shapes, as well as basic mechanisms
of impurity incorporation in melt growth of (in this sense) simple
materials like silicon or organic model substances. In parallel the
experimental techniques to quantitatively ana lyze the various
growth mechanisms have also reached a high level of reproducibility
and precision, giving reliable tests on theoretical predictions.
These basic concepts and appli cations to experiments have been
recently reviewed by one of us (A. A. C. ) in "Modern
Crystallography III. Crystal Growth" (Springer Series on Solid
State Sciences, 1983). It has to be emphasized, however, that for
practical applications we are still unable to quantitatively
calculate many important parameters like kinetic coefficients from
first principles. For mixed systems such as complex oxides,
solutions and systems with chemi cal reactions, our degree of
understanding is even lower. As a few examples for present
achievements we note that experiments with vapour and molecular
beam condensation of alkali halides confirmed the qualitatively
predicted mechanisms of screw dislocations and two-dimensional
nucleation for layer-growth.
