Low-Energy Nuclear Reactions and New Energy is a summary of
selected experimental and theoretical research performed over the
last 19 years that gives profound and unambiguous evidence for low
energy nuclear reaction (LENR), historically known as cold fusion.
In 1989, the subject was announced with great fanfare, to the
chagrin of many people in the science community. However, the
significant claim of its discoverers, Martin Fleischmann and
Stanley Pons, excess heat without harmful neutron emissions or
strong gamma radiation, involving electrochemical cells using heavy
water and palladium, has held strong.
In recent years, LENR, within the field of condensed matter nuclear
science, has begun to attract widespread attention and is regarded
as a potential alternative and renewable energy source to confront
climate change and energy scarcity. The aim of the research is to
collect experimental findings for LENR in order to present
reasonable explanations and a conclusive theoretical and practical
working model.
The goal of the field is directed toward the fabrication of LENR
devices with unique commercial potential demonstrating an
alternative energy source that does not produce greenhouse gases,
long-lived radiation or strong prompt radiation. The idea of LENR
has led to endless discussions about the kinetic impossibility of
intense nuclear reactions with high coulomb barrier potential.
However, recent theoretical work may soon shed light on this
mystery.
Understanding this process is one of the most challenging and
perhaps important issues in the scientific world. This book
includes previously unpublished studies, new and controversial
theories to approach LENR with access to new sources and
experimental results. The book offers insight into this
controversial subject and will help readers re-evaluate their
perspective on LENR as a possible alternative energy source.
Colorimetry is concerned with the measurement of, and
discrimination between, colours. These are important topics in a
wide range of the physical sciences, life sciences, and computing
and engineering. Examples of specific areas where the techniques of
colorimetry are used are: manufacturers of paints, textiles,
plastics and cosmetics (and quality controllers in these
industries), those interested in the effect of light in human
environments (for example, in terms of its direct effects on the
eye, laser safety and design of eye protection and ergonomics of
hospital lighting), psychology, physiology and those involved in
the technical aspects of photography. The book presents the
physiological background behind how colour is perceived and
discusses sources of visible radiation, before going on to describe
in detail colorimetric techniques for measuring and discriminating
between colours. Applications of these techniques are discussed and
relevant mathematical data is provided. The book gives a
comprehensive account of the physiological aspects of colour, the
development of photometry and colorimetry, and applications of
colorimetry in a single volume.

Synchrotron radiation is the name given to the radiation which
occurs when charged particles are accelerated in a curved path or
orbit. Classically, any charged particle which moves in a curved
path or is accelerated in a straight-line path will emit
electromagnetic radiation. Various names are given to this
radiation in different contexts. Thus circular particle
accelerators are called synchrotrons, this is where charged
particles are accelerated to very high speeds and the radiation is
referred to as synchrotron radiation.Suitable for a summer short
course or one term lecture series this text introduces the subject,
starting with some historical background then covering basic
concepts such as flux, intensity, brilliance, emittance and
Liouville's theorem. The book then covers the properties of
synchrotron radiation, insertion devices, beamlines and
monochromators before finishing with an introduction to free
electron lasers and an overview of the most common techniques and
applications of this technology.
This thesis explores two distinct applications of laser
spectroscopy: the study of nuclear ground state properties, and
element selective radioactive ion beam production. It also presents
the methods and results of an investigation into isotope shifts in
the mercury isotopic chain. These Resonance Ionization Laser Ion
Source (RILIS) developments are detailed, together with an RILIS
ionization scheme that allowed laser ionized ion beams of chromium,
germanium, radium and tellurium to be generated at the Isotope Mass
Separator On-Line (ISOLDE) facility. A combination of laser
spectroscopy with decay spectroscopy and mass spectrometry
unambiguously demonstrated a cessation of the extreme shape
staggering first observed in the 1970s and revealed the
characteristic kink at the crossing of the N=126 shell closure. A
series of RILIS developments were required to facilitate this
experiment, including mercury "ionization scheme" development and
the coupling of the RILIS with an arc discharge ion source. Laser
spectroscopy has since become a powerful tool for nuclear physics
and the Resonance Ionization Laser Ion Source (RILIS), of the
ISOLDE facility at CERN, is a prime example. Highlighting important
advances in this field, the thesis offers a unique and revealing
resource.
This book is an introduction to the concept of symmetries in
electromagnetism and explicit symmetry breaking. It begins with a
brief background on the origin of the concept of symmetry and its
meaning in fields such as architecture, mathematics and physics.
Despite the extensive developments of symmetry in these fields, it
has yet to be applied to the context of classical electromagnetism
and related engineering applications. This book unravels the beauty
and excitement of this area to scientists and engineers.
The development of nuclear weapons during the Manhattan Project is
one of the most significant scientific events of the twentieth
century. This revised and updated 4th edition explores the
challenges that faced the scientists and engineers of the Manhattan
Project. It gives a clear introduction to fission weapons at the
level of an upper-year undergraduate physics student by examining
the details of nuclear reactions, their energy release, analytic
and numerical models of the fission process, how critical masses
can be estimated, how fissile materials are produced, and what
factors complicate bomb design. An extensive list of references and
a number of exercises for self-study are included. Revisions to
this fourth edition include many upgrades and new sections.
Improvements are made to, among other things, the analysis of the
physics of the fission barrier, the time-dependent simulation of
the explosion of a nuclear weapon, and the discussion of tamped
bomb cores. New sections cover, for example, composite bomb cores,
approximate methods for various of the calculations presented, and
the physics of the polonium-beryllium "neutron initiators" used to
trigger the bombs. The author delivers in this book an
unparalleled, clear and comprehensive treatment of the physics
behind the Manhattan project.
This book provides detailed information on the electrochemistry of
technetium compounds. After a brief physico-chemical
characterization of this element, it presents the comparative
chemistry of technetium, manganese and rhenium. Particular
attention is paid to the stability, disproportionation,
comproportionation, hydrolysis and polymerization reactions of
technetium ions and their influence on the observed redox systems.
The electrochemical properties of both inorganic as well as organic
technetium species in aqueous and non-aqueous solutions are also
discussed. The respective chapters cover the whole spectrum of
topics related to the application of technetium in nuclear
medicine, electrochemistry of technetium in spent nuclear fuel
(including corrosion properties of technetium alloys), and
detecting trace amounts of technetium with the aid of
electrochemical methods. Providing readers with information not
easily obtained in any other single source, the book will appeal to
researchers working in nuclear chemistry, nuclear medicine or the
nuclear industry.
Separation of Isotopes of Biogenic Elements provides a detailed
overview of this area of research covering all aspects from the
value of isotope effects to their practical use (equilibrium
single-stage isotope effect - kinetics and mass transfer -
multiplication of the single-stage isotope separation factor -
technological peculiarity of processes) with the purpose of
extraction from the natural mixture of the enriched and highly
concentrated isotopes. In contrast to traditional books on the
theory of isotope separation, the theoretical part of the book
describes separation in two-phase processes in counter-flow
columns. The experimental part of the book presents systematic
analysis of specialists in the field of isotope separation in
counter-flow columns. This book will be of interest to scientists,
engineers and technical workers engaged in isotope separation
processes and isotope application in nuclear physics, medicine,
agro-chemistry, biology and other areas. This book may also be used
in teaching theory and practical aspects in courses on physical
chemistry and Isotope separation of light elements by
physicochemical methods.
