This book presents the general concepts of self-organized
spatio-temporal ordering processes. These concepts are demonstrated
via prototypical examples of recent advances in materials science.
Particular emphasis is on nano scale soft matter in physics,
chemistry, biology and biomedicine. The questions addressed embrace
a broad spectrum of complex nonlinear phenomena, ranging from
self-assembling near the thermodynamical equilibrium to dissipative
structure formation far from equilibrium. Their mutual interplay
gives rise to increasing degrees of hierarchical order. Analogues
are pointed out, differences characterized and efforts are made to
reveal common features in the mechanistic description of those
phenomena.
Scattering phenomena play an important role in modern physics. Many
significant discoveries have been made through collision
experiments. Amongst diverse kinds of collision systems, this book
sheds light on the collision of an electron with a molecule. The
electron-molecule collision provides a basic scattering problem. It
is scattering by a nonspherical, multicentered composite particle
with its centers having degrees of freedom of motion. The molecule
can even disintegrate, Le., dissociate or ionize into fragments,
some or all of which may also be molecules. Although it is a
difficult problem, the recent theoretical, experimental, and
computational progress has been so significant as to warrant
publication of a book that specializes in this field. The progress
owes partly to technical develop ments in measurements and
computations. No less important has been the great and continuing
stimulus from such fields of application as astrophysics, the
physics of the earth's upper atmosphere, laser physics, radiation
physics, the physics of gas discharges, magnetohydrodynamic power
generation, and so on. This book aims at introducing the reader to
the problem of electron molecule collisions, elucidating the
physics behind the phenomena, and review ing, to some extent,
up-to-date important results. This book should be appropri ate for
graduate reading in physics and chemistry. We also believe that
investi gators in atomic and molecular physics will benefit much
from this book."
The development and the study of both ionic and electronically
conducting polymers have been. in the past few years. areas of.
increasing interest. These new materials are. in fact. being

The NATO Advanced Study Institute (ASI) on "R@lativistic and
Electron Correlation Effects in Molecules and Solids", co-sponsored
by Simon Fraser University (SFU) and the Natural Sciences and
Engineering Research Council of Canada (NSERC) was held Aug 10- 21,
1992 at the University of British Columbia (UBC), Vancouver,
Canada. A total of 90 lecturers and students with backgrounds in
Chemistry, Physics, Mathematics and various interdisciplinary
subjects attended the ASI. In my proposal submitted to NATO for
financial support for this ASI, I pointed out that a NATO ASI on
the effects of relativity in many-electron systems was held ten
years ago, [See G.L. Malli, (ed) Relativistic Effects in Atoms,
Molecules and Solids, Plenum Press, Vol B87, New York, 1983].
Moreover, at a NATO Advanced Research Workshop (ARW) on advanced
methods for molecular electronic structure "an assessment of
state-of the-art of Electron Correlation ... " was carried out [see
C.E. Dykstra, (ed), Advanced Theories and Computational Approaches
to the Electronic Structure of Molecules, D. Reidel Publishin~
Company, Vol C133, Dordrecht, The Netherlands 1984]. However,
during the last five years, it has become clear that the
relativistic and electron correlation effects must be included in
the theoretical treatment of many-electron molecules and solids of
heavy elements (with Z > 70). Molecules and clusters containing
heavy elements are of crucial importance in a number of areas of
Chemistry and Physics such as nuclear fuels, catalysis, surface
science, etc.
The properties and nature of water clusters studied with novel
spectroscopic approaches are presented in this thesis. Following a
general introduction on the chemistry of water and water clusters,
detailed descriptions of the experiments and analyses are given.
All the experimental results, including first size-selective
spectra of large clusters consisting of 200 water molecules, are
presented with corresponding analyses. Hitherto unidentified
hydrogen bond network structures, dynamics, and reactivity of
various water clusters have been characterized at the molecular
level. The main targets of this book are physical chemists and
chemical physicists who are interested in water chemistry or
cluster chemistry.
This thesis presents an in-depth study on the effect of colloidal
particle shape and formation mechanism on self-organization and the
final crystal symmetries that can be achieved. It demonstrates how
state-of-the-art X-ray diffraction techniques can be used to
produce detailed characterizations of colloidal crystal structures
prepared using different self-assembly techniques, and how smart
systems can be used to investigate defect formation and diffusion
in-situ. One of the most remarkable phenomena exhibited by
concentrated suspensions of colloidal particles is the spontaneous
self-organization into structures with long-range spatial and/or
orientational orders. The study also reveals the subtle structural
variations that arise by changing the particle shape from spherical
to that of a rounded cube. In particular, the roundness of the cube
corners, when combined with the self-organization pathway,
convective assembly or sedimentation, was shown to influence the
final crystal symmetries.
The unique properties and applications of transition metal
compounds have long fascinated both physicists and chemists. This
volume presents theoretical and experimental studies for a deeper
understanding of the electronic and vibronic properties of these
compounds. In particular, an introduction into properties of spin
sublevels of dd*, dA*, and AA* states is given, and a modern ligand
field theory based on the Angular Overlap Model is presented. In
experimental case studies it is shown how to characterize different
types of electronic transitions using modern methods of laser
spectroscopy. Consequences of spin-orbit coupling, zero-field
splittings, spin-lattice relaxations, chromophore-matrix
interactions, Herzberg-Teller/Franck-Condon activities, and
localization/delocalization properties are treated.
This book is a guide to kinetic studies of reaction mechanisms. It
reviews conventional reactor types and data collection methods, and
introduces a new methodology for data collection using Temperature
Scanning Reactors (TSR). It provides a theoretical and practical
approach to temperature scanning (TS) methodology and supports a
revival of kinetic studies as a useful approach to the fundamental
understanding of chemical reaction mechanisms and the consequential
reaction kinetics.

Over the past few years there has been a significant growth in the
commercial application of a variety of processes which are all
essentially based upon the very rapid heat treatment of powdered
solid material in dilute gas suspensions. The objective of flash
heating is usually to create a desirable product by means of
physical and/or chemical transformations in the solid phase,
usually with a high degree of control and with lower specific
energy consumption than dense phase systems. Examples of successful
flash reaction processing are to be found in the areas
ofpyrometallurgy, mineral processing, plasma processing and, most
recently, rapid prototyping. These developments have been based on,
and have inspired, an expansion in fundamental research activities.
As our understanding of flash reaction technology improves so does
the need increase for the review of progress and the dissemination
of accumulated knowl edge. Previous stocktaking on selected areas
of flash reaction technology occurred in 1988 and can be found in
the proceedings of three conferences held in that year: Flash

The conventional solvents used in chemical, pharmaceutical,
biomedical and separation processes represent a great challenge to
green chemistry because of their toxicity and flammability. Since
the beginning of "the 12 Principles of Green Chemistry" in 1998, a
general effort has been made to replace conventional solvents with
environmentally benign substitutes. Water has been the most popular
choice so far, followed by ionic liquids, surfactant, supercritical
fluids, fluorous solvents, liquid polymers, bio-solvents and
switchable solvent systems. Green Solvents Volume I and II provides
a throughout overview of the different types of solvents and
discusses their extensive applications in fields such as
extraction, organic synthesis, biocatalytic processes, production
of fine chemicals, removal of hydrogen sulphide, biochemical
transformations, composite material, energy storage devices and
polymers. These volumes are written by leading international
experts and cover all possible aspects of green solvents'
properties and applications available in today's literature. Green
Solvents Volume I and II is an invaluable guide to scientists,
R&D industrial specialists, researchers, upper-level
undergraduates and graduate students, Ph.D. scholars, college and
university professors working in the field of chemistry and
biochemistry.
"Physical Chemistry in Depth" is not a stand-alone text, but
complements the text of any standard textbook on "Physical
Chemistry" into depth having in mind to provide profound
understanding of some of the topics presented in these textbooks.
Standard textbooks in Physical Chemistry start with thermodynamics,
deal with kinetics, structure of matter, etc. The "Physical
Chemistry in Depth" follows this adjustment, but adds chapters that
are treated traditionally in ordinary textbooks inadequately, e.g.,
general scaling laws, the graphlike structure of matter, and cross
connections between the individual disciplines of Physical
Chemistry. Admittedly, the text is loaded with some mathematics,
which is a prerequisite to thoroughly understand the topics
presented here. However, the mathematics needed is explained at a
really low level so that no additional mathematical textbook is
needed.
The bond valence model, a description of acid-base bonding, is
widely used for analysing and modelling the structures and
properties of solids and liquids. Unlike other models of inorganic
chemical bonding, the bond valence model is simple, intuitive, and
predictive, and is accessible to anyone with a pocket calculator
and a secondary school command of chemistry and physics. This new
edition of 'The Chemical Bond in Inorganic Chemistry: The Bond
Valence Model' shows how chemical properties arise naturally from
the conflict between the constraints of chemistry and those of
three-dimensional space. The book derives the rules of the bond
valence model, as well as those of the traditional covalent, ionic
and popular VSEPR models, by identifying the chemical bond with the
electrostatic flux linking the bonded atoms. Most of the new
edition is devoted to showing how to apply these ideas to real
materials including crystals, liquids, glasses and surfaces. The
work includes detailed examples of applications, and the final
chapter explores the relationship between the flux and quantum
theories of the bond.
Except for digressions in Chapters 8 and 17, this book is a highly
unified treatment of simple oscillations and waves. The phenomena
treated are "simple" in that they are de scribable by linear
equations, almost all occur in one dimension, and the dependent
variables are scalars instead of vectors or something else (such as
electromagnetic waves) with geometric complications. The book omits
such complicated cases in order to deal thoroughly with properties
shared by all linear os cillations and waves. The first seven
chapters are a sequential treatment of electrical and mechanical
oscillating systems, starting with the simplest and proceeding to
systems of coupled oscillators subjected to ar bitrary driving
forces. Then, after a brief discussion of nonlinear oscillations in
Chapter 8, the concept of normal modes of motion is introduced and
used to show the relationship between os cillations and waves.
After Chapter 12, properties of waves are explored by whatever
mathematical techniques are applicable. The book ends with a short
discussion of three-dimensional vii viii Preface problems (in
Chapter 16), and a study of a few aspects of non linear waves (in
Chapter 17)."

This volume presents the proceedings of the 1990 Advanced Study
Institute entitled "Fundamentals of Gas Phase Ion Chemistry" held
at Mont Ste. Odile , Alsace, France, 25th June -6th July, 1990. The
Institute brought together over 100 physicists, physical and
organic chemists working on a wide variety of topics with gas-phase
ion chemistry as the common theme. Many different viewpoints,
making use of very different experimental and theoretical
approaches, were brought to bear on the subject and provided a
stimulating and up-to-date account of the subject. Although the
Institute was built around the invited lectures, many specific
points were addressed in workshops which consisted of informal
discussion groups which were organised by participants during the
Institute. This volume therefore contains not only chapters based
on the lectures but summaries of many of the workshops which adds
considerably to the diversity of information presented. This
Advanced Study Institute was the fifth in a series of
NATO-sponsored institutes devoted to various aspects of the physics
and chemistry of gas phase ions. These meetings have been held
every four years since the first, held in Biarritz in 1974,
considered "Interactions between Ions and Molecules". The five
volumes which comprise the proceedings of these meetings illustrate
very clearly the many advances in theory and experiment which have
taken place over the last 20 years.
Catalysis for Enabling Carbon Dioxide Utilization, Volume 70 in the
Advances in Catalysis series highlights new advances in the field,
with this new volume presenting interesting chapters on a variety
of topics, including Catalytic nonreductive CO2 conversions to
facilitate fine chemical synthesis, Electrochemical transformation
of CO2 into methanol, Electrocatalytic routes towards Carbon
Dioxide Activation and Utilization, Visible-light
photoredox-catalyzed organic transformations with CO2,
Heterogeneous catalysis for the conversion of CO2into cyclic and
polymeric carbonates, and Catalytic synthesis of biosourced organic
carbonates and sustainable hybrid materials from CO2.
This book describes different aspects of characterization and
detection of nanomaterials in liquid disperse systems, such as
suspensions, emulsions and suspoemulsions. Natural and technical
particulate nanomaterials (NMs) are often present in formulations
and products consisting of several disperse phases and complex
dispersion media. Specific interfacial properties of the particles,
their interactions with each other and with the dispersion medium,
have to be considered. For example, the interfacial properties
determine whether the particles tend to be arranged in aqueous or
lipid phases or at their phase boundaries. The interfacial
properties are significantly influenced by the adsorption of
dissolved species, i.e., they depend on the composition of the
dispersion medium. This poses great challenges for the
characterization of these nanoparticle systems and requires
adequate preparation methods. The nanoparticle measurement
techniques aim at a deep physico-chemical understanding of the
dispersity state of nanoparticle systems. Since the dispersity
state of nanoparticle systems in an application usually does not
correspond to their original manufacturing process, the formulation
of new or improved product properties is of decisive importance.
The characterization of nanoparticles in complex formulations or
matrices requires an adequate sample preparation based on an
existing or yet to be developed Standard Operating Procedure (SOP).
The structure of the SOPs includes the dispersion regulations,
which are of essential importance for comparing reproducible
results of nanoparticle measurement with respect to comparability
and transferability worldwide. The aim is to separate and isolate
relevant NMs with knowledge of the interrelationships.
This book presents an important technique to process organic
photovoltaic devices. The basics, materials aspects and
manufacturing of photovoltaic devices with solution processing are
explained. Solution processable organic solar cells - polymer or
solution processable small molecules - have the potential to
significantly reduce the costs for solar electricity and energy
payback time due to the low material costs for the cells, low cost
and fast fabrication processes (ambient, roll-to-roll), high
material utilization etc. In addition, organic photovoltaics (OPV)
also provides attractive properties like flexibility, colorful
displays and transparency which could open new market
opportunities. The material and device innovations lead to improved
efficiency by 8% for organic photovoltaic solar cells, compared to
4% in 2005. Both academic and industry research have significant
interest in the development of this technology. This book gives an
overview of the booming technology, focusing on the solution
process for organic solar cells and provides a state-of-the-art
report of the latest developments. World class experts cover
fundamental, materials, devices and manufacturing technology of OPV
technology.
This textbook introduces the molecular side of physical chemistry.
It offers students and practitioners a new approach to the subject
by presenting numerous applications and solved problems that
illustrate the concepts introduced for varied and complex technical
situations. The book offers a balance between theory, tools, and
practical applications. The text aims to be a practical manual for
solving engineering problems in industries where processes depend
on the chemical composition and physical properties of matter. The
book is organized into three main topics: (I) the molecular
structure of matter, (II) molecular models in thermodynamics, and
(III) transport phenomena and mechanisms. Part I presents methods
of analysis of the molecular behavior in a given system, while the
following parts use these methods to study the equilibrium states
of a material system and to analyze the processes that can take
place when the system is in a state of non-equilibrium, in
particular the transport phenomena. Molecular Physical Chemistry
for Engineering Applications is designed for upper-level
undergraduate and graduate courses in physical chemistry for
engineers, applied physical chemistry, transport phenomena,
colloidal chemistry, and transport/transfer processes. The book
will also be a valuable reference guide for engineers, technicians,
and scientists working in industry. Offers modeling techniques and
tools for solving exercises and practical cases; Provides solutions
and conclusions so students can follow results more closely;
Step-by-step problem solving enables students to understand how to
approach complex issues.
Over the past two decades, two-phase flow and heat transfer
problems associated with two-phase phenomena have been a challenge
to many investigators. Two-phase flow applications are found in a
wide range of engineering systems, such as nuclear and conventional
power plants, evaporators of refrigeration systems and a wide vari
ety of evaporative and condensive heat exchangers in the chemical
industry. This publication is based on the invited lectures
presented at the NATO Advanced Research Workshop on the Advances in
Two-Phase Flow and Heat Transfer. The Horkshop was attended by more
than 50 leading scientists and practicing engineers who work
actively on two-phase flow and heat transfer research and
applications in dif ferent sectors (academia, government, industry)
of member countries of NATO. Some scientific leaders and experts on
the subject matter from the non-NATO countries were also invited.
They convened to discuss the state-of-the-art in two-phase flow and
heat transfer and formulated recommendations for future research
directions. To achieve these goals, invited key papers and a
limited number of contributions were presented and discussed. The
specific aspects of the subject were treated in depth in the panel
sessions, and the unresolved problems identified. Suitable as a
practical reference, these volumes incorporate a systematic
approach to two-phase flow analysis."
