Essentials of Coordination Chemistry: A Simplified Approach with 3D
Visuals provides an accessible overview of this key, foundational
topic in inorganic chemistry. Thoroughly illustrated within the
book and supplemented by online 3D images and videos in full color,
this valuable resource covers basic fundamentals before exploring
more advanced topics of interest. The work begins with an
introduction to the structure, properties, and syntheses of ligands
with metal centers, before discussing the variety of isomerism
exhibited by coordination compounds, such as structural,
geometrical and optical isomerism. As thermodynamics and kinetics
provide a gateway to synthesis and reactivity of coordination
compounds, the book then describes the determination of stability
constants and composition of complexes. Building upon those
principles, the resource then explains a wide variety of
nucleophilic substitution reactions exhibited by both octahedral
and square planar complexes. Finally, the book discusses metal
carbonyls and nitrosyls, special classes of compounds that can
stabilize zero or even negative formal oxidation states of metal
ions. Highlighting preparations, properties, and structures, the
text explores the unique type of Metal-Ligand bonding which enable
many interesting applications of these compounds. Thoughtfully
organized for academic use, Essentials of Coordination Chemistry: A
Simplified Approach with 3D Visuals encourages interactive
learning. Advanced undergraduate and graduate students, as well as
researchers requiring a full overview and visual understanding of
coordination chemistry, will find this book invaluable.
Dealing with the basics, theory and applications of dynamic
pulsed-field-gradient NMR NMR (PFG NMR), this book describes the
essential theory behind diffusion in heterogeneous media that can
be combined with NMR measurements to extract important information
of the system being investigated. This information could be the
surface to volume ratio, droplet size distribution in emulsions,
brine profiles, fat content in food stuff,
permeability/connectivity in porous materials and medical
applications currently being developed. Besides theory and
applications it will provide the readers with background knowledge
on the experimental set-ups, and most important, deal with the
pitfalls that are numerously present in work with PFG-NMR. How to
analyze the NMR data and some important basic knowledge on the
hardware will be explained, too.
The series Topics in Current Chemistry Collections presents
critical reviews from the journal Topics in Current Chemistry
organized in topical volumes. The scope of coverage is all areas of
chemical science including the interfaces with related disciplines
such as biology, medicine and materials science. The goal of each
thematic volume is to give the non-specialist reader, whether in
academia or industry, a comprehensive insight into an area where
new research is emerging which is of interest to a larger
scientific audience. 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 are presented using selected examples to
illustrate the principles discussed. The coverage is not intended
to be an exhaustive summary of the field or include large
quantities of data, but should rather be conceptual, concentrating
on the methodological thinking that will allow the non-specialist
reader to understand the information presented. Contributions also
offer an outlook on potential future developments in the field.
The series Topics in Organometallic Chemistry presents critical
overviews of research results in organometallic chemistry. As our
understanding of organometallic structure, properties and
mechanisms increases, new ways are opened for the design of
organometallic compounds and reactions tailored to the needs of
such diverse areas as organic synthesis, medical research, biology
and materials science. Thus the scope of coverage includes a broad
range of topics in pure and applied organometallic chemistry, where
new breakthroughs are being achieved that are of significance to a
larger scientific audience. The individual volumes of Topics in
Organometallic Chemistry are thematic. Review articles are
generally invited by the volume editors.
This work revolves around the hydrogen economy and energy-storage
electrochemical systems. More specifically, it investigates the
possibility of using magnetron sputtering for deposition of
efficient thin-film anode catalysts with low noble metal content
for proton exchange membrane water electrolyzers (PEM-WEs) and
unitized regenerative fuel cells (PEM-URFCs). The motivation for
this research derives from the urgent need to minimize the price of
such electrochemical devices should they enter the mass production.
Numerous experiments were carried out, correlating the actual
in-cell performance with the varying position of thin-film catalyst
within the membrane electrode assembly, with the composition of
high-surface support sublayer and with the chemical structure of
the catalyst itself. The wide arsenal of analytical methods ranging
from electrochemical impedance spectroscopy through electrochemical
atomic force microscopy to photoelectron spectroscopy allowed the
description of the complex phenomena behind different obtained
efficiencies. Systematic optimizations led to the design of a novel
PEM-WE anode thin-film iridium catalyst which performs similarly to
the standard counterparts despite using just a fraction of their
noble metal content. Moreover, the layer-by-layer approach resulted
in the design of a Ir/TiC/Pt bi-functional anode for PEM-URFC which
is able to operate in both the fuel cell and electrolyzer regime
and thus helps to cut the cost of the whole conversion system even
further.
This detailed book provides a set of protocols necessary for the
development of a variety of microchip-based electrophoretic assays.
It compiles a range of such electrophoretic methods by leading
researchers in the field, covering subjects such as microfluidic
device fabrication, on-chip sample preparation,
theoretical/simulation protocols for assessing these separation
methods, as well as common practices followed when applying them to
important real world applications. The contents of the book range
from protocols for classical assays to those involving pioneering
separation techniques recently developed by the scientific
community for advancing our analytical capabilities. Written for
the highly successful Methods in Molecular Biology series, chapters
include introductions to their respective topics, lists of the
necessary materials and reagents, step-by-step, readily
reproducible laboratory protocols, and tips on troubleshooting and
avoiding known pitfalls. Authoritative and accessible, Microfluidic
Electrophoresis: Methods and Protocols serves as an convenient text
for academic researchers as well as practicing engineers,
biochemists, and analytical laboratory professionals.
This thesis presents experimental and theoretical investigations of
the connection between the time asymmetry in the short-time
evolution of particle clusters and the intrinsic irreversibility of
turbulent flows due to the energy cascade. The term turbulence
describes a special state of a continuous medium in which many
interacting degrees of freedom are excited. One of the interesting
phenomena observed in turbulent flows is their time
irreversibility. When milk is stirred into coffee, for example,
highly complex and interwoven structures are produced, making the
mixing process irreversible. This behavior can be analyzed in more
detail by studying the dispersion of particle clusters. Previous
experimental and numerical studies on the time asymmetry in
two-particle dispersion indicate that particles separate faster
backwards than forwards in time, but no conclusive explanation has
yet been provided. In this thesis, an experimental study on the
short-time behavior of two- and four-particle dispersion in a
turbulent water flow between two counter-rotating propellers is
presented. A brief but rigorous theoretical analysis reveals that
the observed time irreversibility is closely linked to the
turbulence energy cascade. Additionally, it is demonstrated
experimentally that the addition of minute amounts of polymers to
the flow has a significant impact on multi-particle dispersion due
to an alteration of the energy cascade.
State-of-the-art survey by leading experts in the field. Major foci
are superheavy nuclei and neutron-rich exotic nuclei. In addition
new developments in nuclear fission and nuclear cluster decay are
shown. Finally developments in relativistic heavy ion collisions
and the physics of supercritical fields are detailed.
This book reports on the successful implementation of an
innovative, miniaturized galvanic cell that offers unprecedented
control over and access to ionic transport. It represents a
milestone in fundamental studies on the diffusive transport of
lithium ions between two atomically thin layers of carbon
(graphene), a highly relevant aspect in electrodes for energy and
mass storage in the context of batteries. Further, it is a
beautiful example of how interdisciplinary work that combines
expertise from two very distinct fields can significantly advance
science. Machinery and tools common in the study of low-dimensional
systems in condensed matter physics are combined with methods
routinely employed in electrochemistry to enable truly unique and
powerful experiments. The method developed here can easily be
generalized and extended to other layered materials as well as
other ionic species. Not only the method but also the outcome of
its application to Li diffusion and intercalation in bilayer
graphene is remarkable. A record chemical diffusion coefficient is
demonstrated, exceeding even the diffusion of sodium chloride in
water and surpassing any reported value of ion diffusion in
single-phase mixed conducting materials. This finding may be
indicative of the exceptional properties yet to be discovered in
nanoscale derivatives of bulk insertion compounds.
This thesis both broadens and deepens our understanding of the
Brownian world. It addresses new problems in diffusion theory that
have recently attracted considerable attention, both from the side
of nanotechnology and from the viewpoint of pure academic research.
The author focusses on the difussion of interacting particles in
restricted geometries and under externally controlled forces. These
geometries serve, for example, to model ion transport through
narrow channels in cell membranes or a Brownian particle diffusing
in an optical trap, now a paradigm for both theory and experiment.
The work is exceptional in obtaining explicit analytically
formulated answers to such realistic, experimentally relevant
questions. At the same time, with its detailed exposition of the
problems and a complete set of references, it presents a clear and
broadly accessible introduction to the domain. Many of the problem
settings and the corresponding exact asymptotic laws are completely
new in diffusion theory.
The handbook focuses on a complete outline of lithium-ion
batteries. Just before starting with an exposition of the
fundamentals of this system, the book gives a short explanation of
the newest cell generation. The most important elements are
described as negative / positive electrode materials, electrolytes,
seals and separators. The battery disconnect unit and the battery
management system are important parts of modern lithium-ion
batteries. An economical, faultless and efficient battery
production is a must today and is represented with one chapter in
the handbook. Cross-cutting issues like electrical, chemical,
functional safety are further topics. Last but not least standards
and transportation themes are the final chapters of the handbook.
The different topics of the handbook provide a good knowledge base
not only for those working daily on electrochemical energy storage,
but also to scientists, engineers and students concerned in modern
battery systems.
Many new developments, related to the interpretation and importance
of symmetry relationships, quantum mechanics, general relativity,
field theory and mathematics have occurred in the second half of
the 20th century without having a visible impact on chemical
thinking. By re-examining basic theories, The New Theories for
Chemistry aims to introduce a new understanding of old concepts,
such as electron spin, The Periodic Table and electronegativity.
The book focuses on the new mathematical concepts that enable the
exploration of interactions between particles, waves and fields
within a chemical context, and is packed with examples to support
its arguments. The author adopts a practical approach and topics
are arranged sequentially, from the mathematical basis through to
general concepts. An essential reference source, this book is
suitable for physicists, theoretical and physical chemists, as well
as students and researchers working in the field.
* Re-examines basic theories, such as electronegativity and
electron spin, and introduces new theory
* Full of practical experiments and examples
* Is an excellent single reference source
This work takes advantage of high-resolution silicon stencil masks
to build air-stable complementary OTFTs using a low-temperature
fabrication process. Plastic electronics based on organic thin-film
transistors (OTFTs) pave the way for cheap, flexible and large-area
products. Over the past few years, OTFTs have undergone remarkable
advances in terms of reliability, performance and scale of
integration. Many factors contribute to the allure of this
technology; the masks exhibit excellent stiffness and stability,
thus allowing OTFTs with submicrometer channel lengths and superb
device uniformity to be patterned. Furthermore, the OTFTs employ an
ultra-thin gate dielectric that provides a sufficiently high
capacitance to enable the transistors to operate at voltages as low
as 3 V. The critical challenges in this development are the subtle
mechanisms that govern the properties of aggressively scaled OTFTs.
These mechanisms, dictated by device physics, are well described
and implemented into circuit-design tools to ensure adequate
simulation accuracy.
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. Review
articles for the individual volumes are invited by the volume
editors

The first part of this book looks at the consequence of chemical
and topological defects existing on real surfaces, which explain
the wettability of super hydrophilc and super hydrophobic surfaces.
There follows an in-depth analysis of the acido-basicity of
surfaces with, as an illustration, different wettability
experiments on real materials. The next chapter deals with various
techniques enabling the measurement of acido basicity of the
surfaces including IR and XPS technics. The last part of the book
presents an electrochemical point of view which explains the
surface charges of the oxide at contact with water or other
electrolyte solutions in the frame of Bronsted acido-basicity
concept. Various consequences are deduced from such analyses
illustrated by original measurement of the point of zero charge or
by understanding the basic principles of the electrowetting
experiments.
