Biophotonic diagnostics/biomedical spectroscopy can revolutionise
the medical environment by providing a responsive and objective
diagnostic environment. This book aims to explain the fundamentals
of the physical techniques used combined with the particular
requirements of analysing medical/clinical samples as a resource
for any interested party. In addition, it will show the potential
of this field for the future of medical science and act as a driver
for translation across many different biological
problems/questions.
This introduction to quantum field theory (QFT) is written by a
physical chemist for physical chemists, chemical physicists, and
other non-physicists with knowledge of quantum theory but who want
to explore ways in which they might use the power of QFT in their
investigations. This book starts where many graduate courses in
quantum theory that are offered to chemistry students leave off and
first develops some of the necessary tools, such as Fock algebra,
which is applied to solving the quantum oscillator problem. Then it
is used to develop the theory of coherent states, time-dependent
perturbation theory, and the treatment of bosons and fermions. With
this background, the QFT of a perfect gas is derived and a
connection to thermodynamics is demonstrated. Application to
imperfect gases provides a new approach to modelling gas-liquid
phase transitions. The book concludes with photons and their
interaction with molecular ensembles, and brings us to full circle
by deriving the blackbody radiation law, which started it all. The
power of the QFT methodology and the breadth of its applications
should fascinate the reader as it has the author.
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.
Many physical properties of our universe, such as the relative
strength of the fundamental interactions, the value of the
cosmological constant, etc., appear to be fine-tuned for existence
of human life. One possible explanation of this fine tuning assumes
existence of a multiverse, which consists of a very large number of
individual universes having different physical properties.
Intelligent observers populate only a small subset of these
universes, which are fine-tuned for life. In this book we will
review several interesting metamaterial systems, which capture many
features of important cosmological models and offer insights into
the physics of many other non-trivial spacetime geometries, such as
microscopic black holes, closed time-like curves (CTCs) and the
Alcubierre warp drive.
Written in the perspective of an experimental chemist, this book
puts together some fundamentals from chemistry, solid state physics
and quantum chemistry, to help with understanding and predicting
the electronic and optical properties of organic semiconductors,
both polymers and small molecules. The text is intended to assist
graduate students and researchers in the field of organic
electronics to use theory to design more efficient materials for
organic electronic devices such as organic solar cells, light
emitting diodes and field effect transistors. After addressing some
basic topics in solid state physics, a comprehensive introduction
to molecular orbitals and band theory leads to a description of
computational methods based on Hartree-Fock and density functional
theory (DFT), for predicting geometry conformations, frontier
levels and energy band structures. Topological defects and
transport and optical properties are then addressed, and one of the
most commonly used transparent conducting polymers, PEDOT:PSS, is
described in some detail as a case study.
This book presents the design requirements of antenna integration
for modern commercial devices such as smartphones, dongles, and
access points. Practical use-case scenarios of smartphone and the
design process of the antenna system for the same are highlighted.
The feasibility of scaling up sub-6GHz to mmWave antennas is also
discussed in detail followed by a plethora of design examples which
could be panel mounted to modern-day commercial smartphones. The
unique requirement of gain switchability is introduced with
feasible practical antenna designs. High efficiency antennas for 5G
base stations is introduced along with a design example on planar
all-metallic antenna. Beam switchability requirement for base
station is illustrated with a couple of compact antenna system
examples. Variety of feeding techniques for mmWave antennas is
elaborated in this book. Finally, low-cost antenna designs for
future wireless devices are illustrated.
This textbook is a unique and ambitious primer of nuclear physics,
which introduces recent theoretical and experimental progresses
starting from basics in fundamental quantum mechanics. The
highlight is to offer an overview of nuclear structure phenomena
relevant to recent key findings such as unstable halo nuclei,
superheavy elements, neutron stars, nucleosynthesis, the standard
model, lattice quantum chromodynamics (LQCD), and chiral effective
theory. An additional attraction is that general properties of
nuclei are comprehensively explained from both the theoretical and
experimental viewpoints. The book begins with the conceptual and
mathematical basics of quantum mechanics, and goes into the main
point of nuclear physics - nuclear structure, radioactive ion beam
physics, and nuclear reactions. The last chapters devote
interdisciplinary topics in association with astrophysics and
particle physics. A number of illustrations and exercises with
complete solutions are given. Each chapter is comprehensively
written starting from fundamentals to gradually reach modern
aspects of nuclear physics with the objective to provide an
effective description of the cutting edge in the field.
Since the earliest days of human existence, the clash of thunder
and trembling of the hills has struck fear into the hearts of
seasoned warriors and tribal villagers alike. Great gods,
demi-gods, and heroes were created to explain the awesome,
mysterious, and incomprehensibly powerful forces of Nature in a
feeble attempt to make sense of the world around them. To our
advanced scientific minds today, these explanations seem childish
and ridiculous; however, the power to flatten thousands of square
miles of ancient forest, create massive holes in the Earth itself,
and cause mountains to tremble to their very roots are more than
enough reason to believe. Indeed, perhaps our scientific
advancement has caused us to not fully or completely appreciate the
awesome scale and power that Nature can wield against us. The study
of shock wave formation and dynamics begins with a study of waves
themselves. Simple harmonic motion is used to analyze the physical
mechanisms of wave generation and propagation, and the principle of
superposition is used to mathematically generate constructive and
destructive interference. Further development leads to the shock
singularity where a single wave of immense magnitude propagates and
decays through various media. Correlations with the fields of
thermodynamics, meteorology, crater formation, and acoustics are
made, as well as a few special applications. Direct correlation is
made to events in Arizona, Siberia, and others. The mathematical
requirement for this text includes trigonometry, differential
equations, and large series summations, which should be accessible
to most beginning and advanced university students. This text
should serve well as supplementary material in a course covering
discrete wave dynamics, applied thermodynamics, or extreme
acoustics.
Owing to the increased accuracy requirements in fields such as
astrometry and geodesy the general theory of relativity must be
taken into account for any mission requiring highly accurate orbit
information and for practically all observation and measurement
techniques. This book highlights the confluence of Applied
Mathematics, Physics and Space Science as seen from Einstein's
general theory of relativity and aims to bridge the gap between
theoretical and applied domains. The book investigates three
distinct areas of general relativity: Exact solutions of the
Einstein field equations of gravitation. Dynamics of near-Earth
objects and solar system bodies. Relativistic orbitography. This
book is an updated and expanded version of the author's PhD thesis
which was awarded the International Astronomical Union PhD prize in
Division A: Fundamental Astronomy. Included is a new introduction
aimed at graduate students of General Relativity and extended
discussions and results on topics in post-Newtonian dynamics and
general relativistic spacecraft propagation.
This book presents the cold side of the Universe illustrated by the
rest-frame, far-infrared emission with Atacama Large
Millimeter/submillimeter Array (ALMA). The author constructed the
largest-ever ALMA sample and dataset, which enables them to
identify very faint, rest-frame, far-infrared dust continuums as
well as the carbon fine-structure line emission from distant
galaxies that have been missed in previous surveys. The
observational findings described in this book reveal for the first
time where and how much of the star formation, traced by the
rest-frame far-infrared emission, is ongoing, from inter-stellar
and circum-galactic media to cosmic structures. Moreover, since
some of the findings are unexpected and as such challenge the
current galaxy formation models, the book provides exciting
questions that should be addressed in the next decades.
This book is based on a set of 18 class-tested lectures delivered
to fourth-year physics undergraduates at Grifi th University in
Brisbane, and the book presents new discoveries by the Nobel-prize
winning LIGO collaboration. The author begins with a review of
special relativity and tensors and then develops the basic elements
of general relativity (a beautiful theory that unifies special
relativity and gravitation via geometry) with applications to the
gravitational deflection of light, global positioning systems,
black holes, gravitational waves, and cosmology. The book provides
readers with a solid understanding of the underlying physical
concepts; an ability to appreciate and in many cases derive
important applications of the theory; and a solid grounding for
those wishing to pursue their studies further. General Relativity:
An Introduction to Black Holes, Gravitational Waves, and Cosmology
also connects general relativity with broader topics. There is no
doubt that general relativity is an active and exciting field of
physics, and this book successfully transmits that excitement to
readers.
Today, air-to-surface vessel (ASV) radars, or more generally
airborne maritime surveillance radars, are installed on maritime
reconnaissance aircraft for long-range detection, tracking and
classification of surface ships (ASuW--anti-surface warfare) and
for hunting submarines (ASW--anti-submarine warfare). Such radars
were first developed in the UK during WWII as part of the response
to the threat to shipping from German U boats. This book describes
the ASV radars developed in the UK and used by RAF Coastal Command
during WWII for long-range maritime surveillance.
All living matter is comprised of cells, small compartments
isolated from the environment by a cell membrane and filled with
concentrated solutions of various organic and inorganic compounds.
Some organisms are single-cell, where all life functions are
performed by that cell. Others have groups of cells, or organs,
specializing in one particular function. The survival of the entire
organism depends on all of its cells and organs fulfilling their
roles. While the cells are studied by different sciences, they are
seen differently by biologists, chemists, or physicists. Biologists
concentrate their attention on cell structure and function. What
the cells consists of? Where are its organelles? What function each
organelle fulfils? From a chemists' point of view, a cell is a
complex chemical reaction chamber where various molecules are
synthesized or degraded. The main question is how these, sometimes
very complicated chains of reactions are controlled. Finally, from
a physics standpoint, some of the fundamental questions are about
the physical movement of all these molecules between organelles
within the cell, their exchange with the extracellular medium, as
well as electrical phenomena resulting from such transport. The aim
of this book is to look into the basic physical phenomena occurring
in cells. These physical transport processes facilitate chemical
reactions in the cell and various electrical effects, and that in
turn leads to biological functions necessary for the cell to
satisfy its role in the mother organism. Ultimately, the goals of
every cell are to stay alive and to fulfill its function as a part
of a larger organ or organism. The first volume of this book is an
inventory of physical transport processes occurring in cells while
this second volume provides a closer look at how complex biological
and physiological cell phenomena result from these very basic
physical processes.
Renewable energy (RE) is a subject of great interest today. It is
one of the two main means for implementing climate change
mitigation programmes, and presently the only perceived means for
replacing the declining global fossil fuel reserves. It also helps
fight poverty and assists in the global quest for gender equity by
taking clean energy where it is needed most for development. It is
perhaps not surprising therefore that there is so much coverage of
RE in both the conventional media and the internet by media and
tech writers, economists and bloggers, many of who only have a
partial understanding of the technology itself. The end result is
mostly promotional rhetoric that says little about the true value
of the technology, and leads to a confused picture for the serious
individual or decision-maker who wants to know what the technology
is really capable of doing. This book provides a clear and factual
picture of the status of RE and its capabilities today. The need
for such a book was first realized by the author when he was
engaged in a renewable energy capacity-building project
encompassing countries from Europe, the Caribbean, Africa, and the
Pacific. The book is largely non-technical in nature; it does
however contain enough mention of the science and technology to
enable readers to go further with their own investigations should
they wish to. The book covers all areas of renewable energy (RE),
starting from biomass energy and hydropower and proceeding to wind,
solar and geothermal energy before ending with an overview of ocean
energy. It begins with a simple introduction to the physical
principles of the RE technologies, followed by an enumeration of
the requirements for their successful implementation. The last two
chapters consider how the technologies are actually being
implemented today and their roles in climate change mitigation and
poverty alleviation.
Cosmology is the study of the origin, size, and evolution of the
entire universe. Every culture has developed a cosmology, whether
it be based on religious, philosophical, or scientific principles.
In this book, the evolution of the scientific understanding of the
Universe in Western tradition is traced from the early Greek
philosophers to the most modern 21st century view. After a brief
introduction to the concept of the scientific method, the first
part of the book describes the way in which detailed observations
of the Universe, first with the naked eye and later with
increasingly complex modern instruments, ultimately led to the
development of the "Big Bang" theory. The second part of the book
traces the evolution of the Big Bang including the very recent
observation that the expansion of the Universe is itself
accelerating with time.
Stacy Palen knows that introductory astronomy may be the only
science course some students take in their college careers, so it's
their best chance to develop scientific literacy. Education
research shows that the best way to attain scientific literacy is
through active learning. Understanding Our Universe, Fourth Edition
makes it easier for instructors to help students understand the
concepts and learn to value science by providing activities that
can be used before, during and after class. By expanding her
pedagogy to include What If scenarios and What an Astronomer Sees
figure captions, Stacy helps students build scientific literacy and
to think critically about science in the media.
