Multiferroics, materials with a coexistence of magnetic and
ferroelectric order, provide an efficient route for the control of
magnetism by electric fields. The authors cover multiferroic
thin-film heterostructures, device architectures and
domain/interface effects. They critically discuss achievements as
well as limitations and assess opportunities for future
applications.
Electrochemical Nano-biosensors: Applications in Diagnostics,
Therapeutics, Environment, and Food Management features a critical
overview of different, recently reported nanomaterial-based
electrochemical sensing and biosensing strategies. It is based on
various analytical approaches for the point-of-care or POC
healthcare related diagnostics, evaluation of contaminants,
additives and adulterants in foods and environment management. Each
section under the topic is discussed in its exhaustive detail,
incorporating significant literature reviews spanning over two
decades. The book critically analyzes issues and challenges for its
applications in real world settings, universal applicability in
resource limited sets-ups of remote areas, ease of integration with
other sensing platforms, portability/miniaturization, and more.
The first version of quantum theory, developed in the mid 1920's,
is what is called nonrelativistic quantum theory; it is based on a
form of relativity which, in a previous volume, was called Newton
relativity. But quickly after this first development, it was
realized that, in order to account for high energy phenomena such
as particle creation, it was necessary to develop a quantum theory
based on Einstein relativity. This in turn led to the development
of relativistic quantum field theory, which is an intrinsically
many-body theory. But this is not the only possibility for a
relativistic quantum theory. In this book we take the point of view
of a particle theory, based on the irreducible representations of
the Poincare group, the group that expresses the symmetry of
Einstein relativity. There are several ways of formulating such a
theory; we develop what is called relativistic point form quantum
mechanics, which, unlike quantum field theory, deals with a fixed
number of particles in a relativistically invariant way. A central
issue in any relativistic quantum theory is how to introduce
interactions without spoiling relativistic invariance. We show that
interactions can be incorporated in a mass operator, in such a way
that relativistic invariance is maintained. Surprisingly for a
relativistic theory, such a construction allows for instantaneous
interactions; in addition, dynamical particle exchange and particle
production can be included in a multichannel formulation of the
mass operator. For systems of more than two particles, however,
straightforward application of such a construction leads to the
undesirable property that clusters of widely separated particles
continue to interact with one another, even if the interactions
between the individual particles are of short range. A significant
part of this volume deals with the solution of this problem. Since
relativistic quantum mechanics is not as well-known as relativistic
quantum field theory, a chapter is devoted to applications of point
form quantum mechanics to nuclear physics; in particular we show
how constituent quark models can be used to derive electromagnetic
and other properties of hadrons.
Over the last few decades magnetism has seen an enormous expansion
into a variety of different areas of research, notably the
magnetism of several classes of novel materials that share with
truly ferromagnetic materials only the presence of magnetic
moments. Volume 23 of the Handbook of Magnetic Materials, like the
preceding volumes, has a dual purpose. With contributions from
leading authorities in the field, it includes a variety of
self-contained introductions to a given area in the field of
magnetism without requiring recourse to the published literature.
It is also a reference for scientists active in magnetism research,
providing readers with novel trends and achievements in magnetism.
In each of these articles an extensive description is given in
graphical as well as in tabular form, with much emphasis being
placed on the discussion of the experimental material within the
framework of physics, chemistry and material science.
Advances in Heat Transfer fills the information gap between
regularly scheduled journals and university-level textbooks by
providing in-depth review articles over a broader scope than in
journals or texts. The articles, which serve as a broad review for
experts in the field, will also be of great interest to
non-specialists who need to keep up-to-date with the results of the
latest research. This serial is essential reading for all
mechanical, chemical and industrial engineers working in the field
of heat transfer, graduate schools or industry.
The Handbook on the Physics and Chemistry of Rare Earths is a
continuous series of books covering all aspects of rare earth
science - chemistry, life sciences, materials science, and physics.
The main emphasis of the Handbook is on rare earth elements [Sc, Y
and the lanthanides (La through Lu)] but whenever relevant,
information is also included on the closely related actinide
elements. The individual chapters are comprehensive, broad,
up-to-date critical reviews written by highly experienced invited
experts. The series, which was started in 1978 by Professor Karl A.
Gschneidner Jr., combines and integrates both the fundamentals and
applications of these elements and now publishes two volumes a
year.
Quantum mechanics is one of the most fascinating, and at the
same time most controversial, branches of contemporary science.
Disputes have accompanied this science since its birth and have not
ceased to this day.
"Uncommon Paths in Quantum Physics" allows the reader to
contemplate deeply some ideas and methods that are seldom met in
the contemporary literature. Instead of widespread recipes of
mathematical physics, based on the solutions of
integro-differential equations, the book follows logical and partly
intuitional derivations of non-commutative algebra. Readers can
directly penetrate the abstract world of quantum mechanics.
First book in the market that treats this newly developed area of
theoretical physics; the book will thus provide a fascinating
overview of the prospective applications of this area, strongly
founded on the theories and methods that it describes.Provides a
solid foundation for the application of quantum theory to current
physical problems arising in the interpretation of molecular
spectra and important effects in quantum field theory.New insight
into the physics of anharmonic vibrations, more feasible
calculations with improved precision.
Creating Materials with a Desired Refraction Coefficient provides a
recipe for creating materials with a desired refraction
coefficient, and the many-body wave scattering problem for many
small impedance bodies is solved. The physical assumptions make the
multiple scattering effects essential. On the basis of this theory,
a recipe for creating materials with a desired refraction
coefficient is given. Technological problems are formulated which,
when solved, make the theory practically applicable. The Importance
of a problem of producing a small particle with a desired boundary
impedance is emphasized, and inverse scattering with
non-over-determined scattering data is considered.
Advances in Imaging & Electron Physics merges two long-running
serials-Advances in Electronics & Electron Physics and Advances
in Optical & Electron Microscopy. The series features extended
articles on the physics of electron devices (especially
semiconductor devices), particle optics at high and low energies,
microlithography, image science and digital image processing,
electromagnetic wave propagation, electron microscopy, and the
computing methods used in all these domains.
Open microfluidics, the study of microflows having a boundary with
surrounding air, encompasses different aspects such as paper or
thread-based microfluidics, droplet microfluidics and open-channel
microfluidics. Open-channel microflow is a flow at the micro-scale,
guided by solid structures, and having at least a free boundary
(with air or vapor) other than the advancing meniscus. This book is
devoted to the study of open-channel microfluidics which (contrary
to paper or thread or droplet microfluidics) is still very sparsely
documented, but bears many new applications in biology,
biotechnology, medicine, material and space sciences. Capillarity
being the principal force triggering an open microflow, the
principles of capillarity are first recalled. The onset of
open-channel microflow is next analyzed and the fundamental notion
of generalized Cassie angle (the apparent contact angle which
accounts for the presence of air) is presented. The theory of the
dynamics of open-channel microflows is then developed, using the
notion of averaged friction length which accounts for the presence
of air along the boundaries of the flow domain. Different channel
morphologies are studied and geometrical features such as valves
and capillary pumps are examined. An introduction to two-phase
open-channel microflows is also presented showing that immiscible
plugs can be transported by an open-channel flow. Finally, a
selection of interesting applications in the domains of space,
materials, medicine and biology is presented, showing the
potentialities of open-channel microfluidics.
Principles of Nucleic Acid Structure, Second Edition, provides the
most complete and concise summary of underlying principles and
approaches to studying nucleic acid structure, including
discussions of X-ray crystallography, NMR, molecular modelling and
databases. The book's focus is on a survey of structures that are
especially important for biomedical research and pharmacological
applications. This updated edition includes the latest advances
relevant to recognition of DNA and RNA by small molecules and
proteins, including sections on RNA folding, ribosome structure and
antibiotic interactions, DNA quadruplexes, DNA and RNA protein
complexes and short interfering RNA (siRNA). This reference is a
must-have for those seeking an authoritative, comprehensive and
up-to-date source on all aspects of nucleic acid structure, from
basic first principles to details of recent research results.
This second edition of Medical Biochemistry is supported by more
than 45 years of teaching experience, providing coverage of basic
biochemical topics, including the structural, physical, and
chemical properties of water, carbohydrates, lipids, proteins, and
nucleic acids. In addition, the general aspects of thermodynamics,
enzymes, bioenergetics, and metabolism are presented in
straightforward and easy-to-comprehend language. This book ties
these concepts into more complex aspects of biochemistry using a
systems approach, dedicating chapters to the integral study of
biological phenomena, including cell membrane structure and
function, gene expression and regulation, protein synthesis and
post-translational modifications, metabolism in specific organs and
tissues, autophagy, cell receptors, signal transduction pathways,
biochemical bases of endocrinology, immunity, vitamins and
minerals, and hemostasis. The field of biochemistry is continuing
to grow at a fast pace. This edition has been revised and expanded
with all-new sections on the cell plasma membrane, the human
microbiome, autophagy, noncoding, small and long RNAs, epigenetics,
genetic diseases, virology and vaccines, cell signaling, and
different modes of programmed cell death. The book has also been
updated with full-color figures, new tables, chapter summaries, and
further medical examples to improve learning and better illustrate
the concepts described and their clinical significance.
