the history of BioMEMS and the design and manufacture of the first
bioMEMS-based devices.
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
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.
* Written by a leading scholar and industry expert
* Presents new and cutting edge material encouraging innovation and
future research
* Connects hot topics and leading research in one concise volume
High-resolution X-ray spectroscopy has become a powerful tool for
astrophysics since the launch of Chandra and XMM-Newton, ten years
ago. The grating spectrometers on both instruments still continue
to provide excellent data, while imaging calorimeters are being
prepared for future missions like Astro-H and IXO. The synergy with
other wavelength bands like the UV has been boosted by the addition
of COS to HST. X-ray spectroscopy offers unique diagnostics to
study almost any object in the Universe. This book contains review
papers on highlights and the state-of-the-art of X-ray spectroscopy
for a broad range of objects and on the prospects for future
studies.

imaging. In chapters written by key opinion leaders in the field,
it covers a broad range of topics, including fundamentals,
principles, instrumentation, image reconstruction and data/image
processing methods, preclinical and clinical applications of
LED-based photoacoustic imaging. Apart from preclinical imaging
studies and early clinical pilot studies using LED-based
photoacoustics, the book includes a chapter exploring the
opportunities and challenges of clinical translation from an
industry perspective. Given its scope, the book will appeal to
scientists and engineers in academia and industry, as well as
medical experts interested in the clinical applications of
photoacoustic imaging.
This book discusses fundamentally new biomedical imaging methods,
such as holography, holographic and resonant interferometry, and
speckle optics. It focuses on the development of holographic
interference microscopy and its use in the study of phase objects
such as nerve and muscle fibers subjected to the influence of laser
radiation, magnetic fields, and hyperbaric conditions. The book
shows how the myelin sheath and even the axon itself exhibit
waveguide properties, enabling a fresh new look at the mechanisms
of information transmission in the human body. The book presents
theoretically and experimentally tested holographic and
speckle-optical methods and devices used for investigating complex,
diffusely scattering surfaces such as skin and muscle tissue.
Additionally, it gives broad discussion of the authors' own
original fundamental and applied research dedicated to helping
physicians introduce new contact-less methods of diagnosis and
treatment of diseases of the cardiovascular and neuromuscular
systems into medical practice. The book is aimed at a broad
spectrum of scientific specialists in the fields of speckle optics,
holography, laser physics, morphology and cytochemistry, as well as
medical professionals such as physiologists, neuropathologists,
neurosurgeons, cardiologists and dentists.
The book reviews photosynthetic water oxidation and proton-coupled
electron transfer in photosystem, focusing on the molecular
vibrations of amino acid residues and water molecules.
Photosynthetic water oxidation performed by plants and
cyanobacteria is essential for the sustenance of life on Earth, not
only as an electron source for synthesizing sugars from CO2, but
also as an O2 source in the atmosphere. Water oxidation takes place
at the Mn4CaO5 cluster in photosystem II, where a series of
electron transfer reactions coupled with proton transfer occur
using light energy. The author addresses the unresolved mechanisms
of photosynthetic water oxidation and relevant proton-coupled
electron transfer reactions using a combined approach of
experimental and computational methods such as Fourier transform
infrared difference spectroscopy and quantum chemical calculations.
The results show that protonation and hydrogen-bond structures of
water molecules and amino acid residues in the protein play
important roles in regulation of the electron and proton transfer
reactions. These findings and the methodology make a significant
contribution to our understanding the molecular mechanism of
photosynthetic water oxidation.
This book highlights emerging trends in terahertz engineering and
system technologies, mainly, devices, advanced materials, and

tomographic reconstruction for THz biomedical imaging by use of
machine learning and artificial intelligence, THz imaging radars
for autonomous vehicle applications, THZ imaging system for
security and surveillance. It also discusses theoretical,
experimental, established and validated empirical work on these
topics and the intended audience is both academic and professional.
This book explores the use of biomass as an energy source and its
application in energy conversion technologies. Focusing on the
challenges of, and technologies related to, biomass conversion, the
book is divided into three parts. The first part underlines the
fundamental concepts that form the basis of biomass production, its
feasibility valuation, and its potential utilization. This part
does not consider only how biomass is generated, but also methods
of assessment. The second part focuses on the clarification of
central concepts of the biorefinery processes. After a preliminary
introduction with industrial examples, common issues of biochemical
reaction engineering applications are analysed in detail. The
theory explained in this part demonstrates that the chemical
kinetics are the core focus in modelling biological processes such
as growth, decay, product formation and feedstock consumption. This
part continues with the theory of biofuels production, including
biogas, bioethanol, biodiesel and Fischer-Tropsch synthesis of
hydrocarbons. The third part of this book gives detailed
explanations of preliminary notions related to the theory of
thermodynamics. This theory will assist the reader when taking into
account the concepts treated in the previous two parts of the book.
Several detailed derivations are given to give the reader a full
understanding of the arguments at hand. This part also gives
literature data on the main properties of some biomass feedstock.
Fundamentals of Biofuels Engineering and Technology will be of
interest not only to academics and researchers working in this
field but also to graduate students and energy professionals
seeking to expand their knowledge of this increasingly important
area.

This book introduces readers to the latest advances in G
protein-coupled receptor (GPCR) biology. It reviews our current
understanding of the structural basis of ligand binding and
allosteric mechanisms, following a decade of technological
breakthroughs. Several examples of structure-based drug discovery
are presented, together with the future challenges involved in
designing better drugs that target GPCRs. In turn, the book
illustrates the important concept of GPCR biased signaling in
physiological contexts, and presents fluorescent- and light-based
methodologies frequently used to measure GPCR signaling or to trace
their dynamics in cells upon ligand activation. Taken together, the
chapters provide an essential overview and toolkit for new
scientific investigators who plan to develop GPCR projects. All
chapters were written by experts in their respective fields, and
share valuable insights and powerful methodologies for the GPCR
field.
This book presents the latest advances and future trends in
electron and phonon spectrometrics, focusing on combined techniques
using electron emissions, electron diffraction, and phonon
absorption and reflection spectrometrics from a substance under
various perturbations to obtain new information on
bond-electron-phonon dynamics. Discussing the principles of the
bond order-length-strength (BOLS) correlation, nonbonding electron
polarization (NEP), local bond average (LBA), and multi-field
lattice oscillation dynamics for systems under perturbation, the
book covers topics like differential photoelectron/phonon
spectrometrics (DPS), which distils transition of the length,
energy, stiffness and the fraction of bonds upon chemical or
physical conditioning; and the derived performance of electrons in
various bands in terms of quantum entrapment and polarization. This
book appeals to researchers, scientists and engineers in the fields
of chemistry, physics, surface and interface science, and materials
science and engineering who are interested in electron and phonon
spectrometrics.
Micro-Raman Spectroscopy introduces readers to the theory and
application of Raman microscopy. Raman microscopy is used to study
the chemical signature of samples with little preperation in a
non-destructive manner. An easy to use technique with ever
increasing technological advances, Micro-Raman has significant
application for researchers in the fields of materials science,
medicine, pharmaceuticals, and chemistry.
This book reports new findings in the fields of nonlinear optics,
quantum optics and optical microscopy. It presents the first
experimental device able to transform an input Gaussian beam into a
non-diffracting Bessel-like beam. The modulation mechanism, i.e.
electro-optic effect, allows the device to be fast, miniaturizable
and integrable into solid state arrays. Also presented is an
extensive study of the superposition of Bessel beams and their
propagation in turbid media, with the aim of realizing field that
is both localized and non-diffracting. These findings have been
implemented in a light-sheet microscope to improve the optical
sectioning. From a more theoretical point of view this work also
tackles the problem of whether and how a single particle is able to
entangle two distant systems. The results obtained introduce
fundamental limitations on the use of linear optics for quantum
technology. Other chapters are dedicated to a number of experiments
carried out on disordered ferroelectrics including negative
intrinsic mass dynamics, ferroelectric supercrystals, rogue wave
dynamics driven by enhanced disorder and first evidence of spatial
optical turbulence.
This book offers a pragmatic guide to navigating through the
complex maze of EPR/ESR spectroscopy fundamentals, techniques, and
applications. Written for the scientist who is new to EPR
spectroscopy, the editors have prepared a volume that de-mystifies
the basic fundamentals without weighting readers down with detailed
physics and mathematics, and then presents clear approaches in
specific application areas. The first part presents basic
fundamentals and advantages of electron paramagnetic resonance
spectrscopy. The second part explores severalapplication areas
including chemistry, biology, medicine, materials and geology. A
frequently-asked-questions sections focuses on practicalquestions,
such as the size of sample, etc. It's an ideal, hands-on reference
for chemists and researchers in the pharmaceutical and materials
(semiconductor) industries who are looking for a basic introduction
to EPR spectroscopy.
The knowledge base of chromatography continued to expand throughout
the 1990s owing to its many applications to problems of
contemporary interest in industry, life and environmental sciences.
Organizing this information into a single text for a diverse group
of scientists has become increasingly difficult. The present book
stemmed from the desire to revise Chromatography Today, written by
the same author with Salwa K. Poole, and published in 1991. This
title is considered to be one of the definitive texts on
chromatography. It was soon realized however, that a simple
revision would not provide the desired result of a contemporary
picture of the practice of chromatography at the turn of the
century. The only workable solution was to start afresh,
maintaining the same general philosophy and concept for
Chromatography Today where possible, while creating essentially a
new book.
The format of the new book is modular, with extensive
cross-references to permit rapid location of related material using
different separation concepts. Important features are extensive
tabulation of essential data for performing separations and an
extensive bibliography to the most recent literature.
This title is intended as a suitable text for graduate level
courses in the separation sciences and as a self-study guide for
professional chromatographers wishing to refresh their background
in this rapidly expanding field.
The Essence of Chromatography presents a comprehensive survey of
modern chromatography and is an effective replacement for
Chromatography Today.
.Comprehensive and authoritative coverage of chromatographic
techniques
.Contains extensive coverage of recent literature on this
subject
.Ideal text for graduates and suitable for professional
chromatographers"
This book explores emerging topics in atomic- and nano-scale
electronics after the era of Moore's Law, covering both the
physical principles behind, and technological implementations for
many devices that are now expected to become key elements of the
future of nanoelectronics beyond traditional complementary
metal-oxide semiconductors (CMOS). Moore's law is not a physical
law itself, but rather a visionary prediction that has worked well
for more than 50 years but is rapidly coming to its end as the gate
length of CMOS transistors approaches the length-scale of only a
few atoms. Thus, the key question here is: "What is the future for
nanoelectronics beyond CMOS?" The possible answers are found in
this book. Introducing novel quantum devices such as atomic-scale
electronic devices, ballistic devices, memristors, superconducting
devices, this book also presents the reader with the physical
principles underlying new ways of computing, as well as their
practical implementation. Topics such as quantum computing,
neuromorphic computing are highlighted here as some of the most
promising candidates for ushering in a new era of atomic-scale
electronics beyond CMOS.
