This series is world-renowned as the leading compilation of current
reviews of this vast field. Internationally acclaimed for more than
40 years, "The Alkaloids: Chemistry and Biology, " founded by the
late Professor R.H.F. Manske, continues to provide outstanding
coverage of this rapidly expanding field. Each volume provides,
through its distinguished authors, up-to-date and detailed coverage
of particular classes or sources of alkaloids.
* Up-to-date reviews on a large and very important group of natural
products from both a chemical and biological perspective.
* Comprehensive, dynamic reviews written by leading authors in the
respective fields.
* Broad coverage on the biological aspects.
ReAction gives a scientist's and artist's response to the dark and
bright sides of chemistry found in 140 films, most of them
contemporary Hollywood feature films but also a few documentaries,
shorts, silents, and international films.
Even though there are some examples of screen chemistry between the
actors and of behind-the-scenes special effects, this book is
really about the chemistry when it is part of the narrative. It is
about the dualities of Dr. Jekyll vs. inventor chemists, the
invisible man vs. forensic chemists, chemical weapons vs. classroom
chemistry, chemical companies that knowingly pollute the
environment vs. altruistic research chemists trying to make the
world a better place to live, and, finally, about people who choose
to experiment with mind-altering drugs vs. the drug discovery
process.
Little did Jekyll know when he brought the Hyde formula to his lips
that his personality split would provide the central metaphor that
would come to describe chemistry in the movies. This book explores
the two movie faces of this supposedly neutral science. Watching
films with chemical eyes, Dr. Jekyll is recast as a chemist engaged
in psychopharmaceutical research but who becomes addicted to his
own formula. He is balanced by the often wacky inventor chemists
who make their discoveries by trial-and-error.
The aim of this volume is to present the basic mathematical aspects
of the ranking methods using a didactical approach and to explain
their use through examples of relevant applications in different
scientific fields. Ranking methods can be applied in several
different fileds, such as decision support, toxicology, EU priority
lists of toxic chemicals, environmental problems, proteomics and
genomics, analytical chemistry, food chemistry and QSAR.
. Covers a wide range of applications, from the environment and
toxicology to DNA sequencing
. Incorporates contributions from renowned experts in the
field
. Meets the increasing demand for literature concerned with ranking
methods and their applications
Surface-Enhanced Raman Scattering (SERS) was discovered in the
1970s and has since grown enormously in breadth, depth, and
understanding. One of the major characteristics of SERS is its
interdisciplinary nature: it lies at the boundary between physics,
chemistry, colloid science, plasmonics, nanotechnology, and
biology. By their very nature, it is impossible to find a textbook
that will summarize the principles needed for SERS of these rather
dissimilar and disconnected topics. Although a basic understanding
of these topics is necessary for research projects in SERS with all
its many aspects and applications, they are seldom touched upon as
a coherent unit during most undergraduate studies in physics or
chemistry. This book intends to fill this existing gap in the
literature. It provides an overview of the underlying principles of
SERS, from the fundamental understanding of the effect to its
potential applications. It is aimed primarily at newcomers to the
field, graduate student, researcher or scientist, attracted by the
many applications of SERS and plasmonics or its basic science. The
emphasis is on concepts and background material for SERS, such as
Raman spectroscopy, the physics of plasmons, or colloid science,
all of them introduced within the context of SERS, and from where
the more specialised literature can be followed.
* Represents one of very few books fully dedicated to the topic of
surface-enhanced Raman spectroscopy (SERS)
* Gives a comprehensive summary of the underlying physical concepts
around SERS
* Provides a detailed analysis of plasmons and plasmonics
For almost a decade, quantitative NMR spectroscopy (qNMR) has been
established as valuable tool in drug analysis. In all disciplines,
i. e. drug identification, impurity profiling and assay, qNMR can
be utilized.
Separation techniques such as high performance liquid
chromatography, gas chromatography, super fluid chromatography and
capillary electrophoresis techniques, govern the purity evaluation
of drugs. However, these techniques are not always able to solve
the analytical problems often resulting in insufficient methods.
Nevertheless such methods find their way into international
pharmacopoeias. Thus, the aim of the book is to describe the
possibilities of qNMR in pharmaceutical analysis.
Beside the introduction to the physical fundamentals and techniques
the principles of the application in drug analysis are described:
quality evaluation of drugs, polymer characterization, natural
products and corresponding reference compounds, metabolism, and
solid phase NMR spectroscopy for the characterization drug
substances, e.g. the water content, polymorphism, and drug
formulations, e.g. tablets, powders. This part is accompanied by
more special chapters dealing with representative examples. They
give more detailed information by means of concrete examples.
- combines theory, techniques, and concrete applications-all of
which closely resemble the laboratory experience
- considers international pharmacopoeias, addressing the concern
for licensing
- features the work of academics and researchers, appealing to a
broad readership

The aim of this book is to describe some aspects of the chemistry
and chemical ecology which are found in the garden. In the garden
there are numerous interactions between plants, the soil and with
other organisms in which chemistry plays a central mediating role.
The discussion concerns several of the chemically and ecologically
interesting compounds that are produced by common ornamental garden
plants and vegetables and by the predators that attack them. Many
chemists are amateur gardeners and this book is directed at them as
well as those with a general interest in the scientific processes
involved in the garden.
A classical metastable state possesses a local free energy minimum
at infinite sizes, but not a global one. This concept is phase size
independent. We have studied a number of experimental results and
proposed a new concept that there exists a wide range of metastable
states in polymers on different length scales where their
metastability is critically determined by the phase size and
dimensionality. Metastable states are also observed in phase
transformations that are kinetically impeded on the pathway to
thermodynamic equilibrium. This was illustrated in structural and
morphological investigations of crystallization and mesophase
transitions, liquid-liquid phase separation, vitrification and gel
formation, as well as combinations of these transformation
processes. The phase behaviours in polymers are thus dominated by
interlinks of metastable states on different length scales. This
concept successfully explains many experimental observations and
provides a new way to connect different aspects of polymer physics.

* Presents new and cutting edge material encouraging innovation and
future research
* Connects hot topics and leading research in one concise volume
Water in the proximity of a surface (interfacial water) is abundant
on the earth. It is involved in various physical and chemical
processes and crucial for biological function. Despite numerous
studies of interfacial water, systematic analysis of its properties
is missing in scientific literature. This book is a first
comprehensive review of experimental and simulation studies of
water in various confining environments, such as hydrophilic and
hydrophobic surfaces, surfaces of biomolecules, porous media, etc.
Systematic analysis of interfacial and confined water is based on
the firm physical ground, which accounts for variety of the
thermodynamic states of water near the surface, surface phase
transitions, surface critical behaviour, effect of confinement on
the bulk and surface phase transitions of water, clustering and
formation of a spanning hydrogen-bonded water network via
percolation transition. This allows distinguishing between
universal features, common for all fluids, and some specific water
properties, related to intermolecular hydrogen bonds. Special
attention is paid to the properties of hydration water, which
covers biomolecules and enables their biological activity. This
book provides readers with basic information on interfacial and
confined water, which will be useful for scientists and engineers
working in the fields of bioscienses, nanociences and
nanotechnologies.
* Comprehensive review and analysis of interfacial and confined
water
* Updates and informs practitioners and students on all the latest
developments in the field
* Written by leading scholars and industry experts

covers advances in the field since the previous edition published
in 2009. Subject of note include updates in the fields of
multidimensional and megavariate data analysis, omics data
analysis, big chemical and biochemical data analysis, data fusion
and sparse methods. The book follows a similar structure to the
previous edition, using the same section titles to frame articles.
Many chapters from the previous edition are updated, but there are
also many new chapters on the latest developments.
During the past 30 years, the field of alkene polymerization over
transition metal catalysts underwent several major changes:
1. The list of commercial heterogeneous Ziegler-Natta catalysts for
the synthesis of polyethylene and stereoregular polyolefins was
completely renewed affording an unprecedented degree of control
over the polymer structure.
2. Research devoted to metallocene and other soluble
transition-metal catalysis has vastly expanded and has shifted
toward complexes of transition metals with multidentate
ligands.
3. Recent developments in gel permeation chromatography,
temperature-rising fractionation, and crystallization fractionation
provided the first reliable information about differences between
various active centers in transition-metal catalysts.
4. A rapid development of high-resolution 13C NMR spectroscopy
resulted in greatly expanded understanding of the chemical and
steric features of polyolefins and alkene copolymers.
These developments require a new review of all aspects of alkene
polymerization reactions with transition-metal catalysts. The first
chapter in the book is an introductory text for researchers who are
entering the field. It describes the basic principles of
polymerization reactions with transition-metal catalysts, the types
of catalysts, and commercially manufactured polyolefins.
The next chapter addresses the principal issue of alkene
polymerization catalysis: the existence of catalyst systems with
single and multiple types of active centers. The subsequent
chapters are devoted to chemistry and stereochemistry of elemental
reaction steps, structures of catalyst precursors and reactions
leading to the formation of active centers, kinetics of
polymerization reactions, and their mechanisms.
The book describes the latest commercial polymerization catalysts
for the synthesis of polyethylenes and polypropylene
The book provides a detailed description of the multi-center
nature of commercial Ziegler-Natta catalysts.
The book devotes specialized chapters to the most important
aspects of transition metal polymerization catalysts: the reactions
leading to the formation of active centers, the chemistry and
stereochemistry of elemental polymerization steps, reaction
kinetics, and the polymerization mechanism.
The book contains an introductory chapter for researchers who are
entering the field of polymerization catalysis. It describes the
basic principles of polymerization reactions with transition-metal
catalysts and the types of commercially manufactured polyolefins
and copolymers
The book contains over 2000 references, the most recent up to end
of 2006.
