The "greening" of industry processes - i.e., making them more
sustainable - is a popular and often lucrative trend which has seen
increased attention in recent years. Green Chemical Processes, the
2nd volume of Green Chemical Processing, covers the hot topic of
sustainability in chemistry with a view to education, as well as
considering corporate and environmental interests, e.g. in the
context of energy production. The diverse team of authors allows
for a balance between these different, but interconnected
perspectives. The American Chemical Society's 12 Principles of
Green Chemistry are woven throughout this text as well as the
series to which this book belongs.
This volume presents the selected papers of the First International
Conference on Fundamental Research in Electrical Engineering, held
at Khwarazmi University, Tehran, Iran in July, 2017. The selected
papers cover the whole spectrum of the main four fields of
Electrical Engineering (Electronic, Telecommunications, Control,
and Power Engineering).
Wireless Sensor Networks (WSNs) and the Internet of Things are
facing tremendous advances both in terms of energy-efficiency as
well as in the number of available applications. Consequently,
there are challenges that need to be tackled for the future
generation of WSNs. After giving an overview of the WSN protocols
and IEEE 802.15.4 standard, this book proposes IEEE 802.15.4 Medium
Access Control (MAC) sub-layer performance enhancements by
employing not only RTS/CTS combined with packet concatenation but
also scheduled channel poling (MC-SCP). Results have shown that the
use of the RTS/CTS mechanism improves channel efficiency by
decreasing the deferral time before transmitting a data packet.
Furthermore, the Sensor Block Acknowledgment MAC (SBACK-MAC)
protocol enables more efficiency as it allows the aggregation of
several acknowledgement responses in one special Block
Acknowledgment (BACK) Response packet. The throughput and delay
performance have been mathematically derived under both ideal
conditions (a channel environment with no transmission errors) and
non-ideal conditions (with transmission errors). Simulation results
successfully validate the proposed analytical models. This research
reveals the importance of an appropriate design for the MAC
sub-layer protocol for the desired WSN application. Depending on
the mission of the WSN application, different protocols are
required. Therefore, the overall performance of a WSN application
certainly depends on the development and application of suitable
e.g., MAC, network layer protocols.
Green Composites: Waste-based Materials for a Sustainable Future,
Second Edition presents exciting new developments on waste-based
composites. New, additional, or replacement chapters focus on these
elements, reflecting on developments over the past ten years.
Authors of existing chapters have brought these themes into their
work wherever possible, and case study chapters that connect
materials engineering to the topic's social context are included in
this revised edition. Professor Baillie believes that the new
'green' is the "what and who" composites are being designed for,
"what" material needs we have, and "what" access different groups
have to the technical knowledge required, etc. Industry is now
showing concerns for corporate social responsibility and social
impact. Recent conversations with prestigious materials
institutions have indicated a growing interest in moving into areas
of research that relate their work to beneficial social impacts.
The book's example of Waste for Life demonstrates the genre
proposed for the case study chapters. Waste for Life adopts
scientific knowledge and low-threshold/high-impact technologies.

This book provides a comprehensive overview of the main nuclear
characterization techniques used to study hydrogen absorption and
desorption in materials. The various techniques (neutron
scattering, nuclear magnetic resonance, ion-beams, positron
annihilation spectroscopy) are explained in detail, and a variety
of examples of recent research projects are given to show the
unique advantage of these techniques to study hydrogen in
materials. Most of these nuclear techniques require very
specialized instrumentation, and there are only a handful of these
instruments available worldwide. Therefore, the aim of this book is
to reach out to a readership with a very diverse background in the
physical sciences and engineering and a broad range of
hydrogen-related research interests. The same technique can be used
by researchers interested in the improvement of the performance of
hydrogen storage materials and by those focused on hydrogen ingress
causing embrittlement of metals. The emphasis of this book is to
provide tutorial material on how to use nuclear characterization
techniques for the investigation of hydrogen in materials -
information that cannot readily be found in conference and regular
research papers. Provides a comprehensive overview of nuclear
techniques used for hydrogen-related research Explains all nuclear
techniques in detail for the non-expert Covers the whole range of
hydrogen-related research Features chapters written by
world-renowned experts in nuclear technique and hydrogen-related

Providing a valuable resource to energy engineers, chemical
engineers, biotechnologists and economists, this book will also be
of great interest to students and policymakers.
In January 1998 a massive ice storm descended on New York, New
England, and eastern Canada. It crushed power grids from the Great
Lakes to the North Atlantic, forcing thousands of people into
public shelters and leaving millions of others in their homes
without electricity. In this riveting book Stephen Doheny-Farina
presents an insider's account of these events, describing the
destruction of the electric network in his own village and the
emergence of the face-to-face interactions that took its place. His
stories examine the impact of electronic communications on
community, illuminating the relationship between electronic and
human connections and between networks and neighborhoods, and
exploring why and how media portrayals of disasters can distort
authentic experience. Doheny-Farina begins by discussing the
disaster and tracing the origins of the storm. He then goes back
two hundred years to tell how this particular electric grid was
built, showing us the sacrifices people made to create the grids
that (usually) connect us to one another. Today's power grid, says
Doheny-Farina, has become more vulnerable than we realize, as
demand begins to outstrip capacity in urban centers around the
nation. His book reminds us what those grids mean-both positively
and negatively-to our electronically saturated lives.
People scratching a living from parched land, women walking miles
for scraps of firewood are both familiar images of Africa. But, in
many places, people, with the help of governments and aid agencies,
are putting the land into good shape, growing more food and
creating a healthy cover of trees. This book joins the literature
of hope by looking at these advances from the viewpoint of the
energy crisis of the poor. This crisis can only be solved by going
beyond the narrow confines of energy to consider all the needs of
local people and the potential for change. Drawing on a wide range
of case histories, the authors describe the gains in farming and
forestry and woodfuel supply that have come about through this
broader, people-centered approach. They also write about woodfuel
prices, markets and other key elements of survival strategies for
the cities. Huge efforts will be needed to recover from the
failures of the past, but Leach and Mearns show that important
lessons are at last being learned and that new roads to success can
be mapped. Originally published in 1988

This thesis investigates the key characteristics of magnetless
doubly salient machines, evaluates their design philosophies, and
proposes new topologies for various applications. It discusses the
background of and previous research on magnetless machines, while
also outlining upcoming trends and potential future developments.
The thesis begins by presenting various torque-improving structures
- namely the multi-tooth structure, the double-rotor (DR)
structure, the axial-field (AF) structure, and the flux-reversal
(FR) structure - for magnetless machines. It subsequently addresses
the idea of merging the design philosophies of two different
machines to form new dual-mode machines. Thanks to a reconfigured
winding arrangement and controllable DC-field excitation, the
proposed machines can further extend their operating range to meet
the extreme demands of applications in electric vehicles and wind
power generation. Lastly, the thesis employs the finite element
method (FEM) to thoroughly analyze the proposed machines' key
performance parameters and develops experimental setups to verify
the proposed concepts.

of information on boiling springs and hot springs, including their
location and elevation, temperature, geological characteristics,
and water chemical data, as well as tables on warm and tepid
springs. Shedding new light on this vital supplement to
hydroelectric resources in remote southwest China, the book will
appeal to a broad relationship, from experts researching the
Tibetan Plateau to companies specializing in geothermal
exploration.
This book discusses the physics of the dynamics of ions in various
ionically conducting materials, and applications including
electrical energy generation and storage. The experimental
techniques for measurements and characterization, molecular
dynamics simulations, the theories of ion dynamics, and
applications are all addressed by the authors, who are experts in
their fields. The experimental techniques of measurement and
characterization of dynamics of ions in glassy, crystalline, and
liquid ionic conductors are introduced with the dual purpose of
introducing the reader to the experimental activities of the field,
and preparing the reader to understand the physical quantities
derived from experiments. These experimental techniques include
calorimetry, conductivity relaxation, nuclear magnetic resonance,
light scattering, neutron scattering, and others. Methods of
molecular dynamics simulations are introduced to teach the reader
to utilize the technique for practical applications to specific
problems. The results elucidate the dynamics of ions on some issues
that are not accessible by experiments. The properties of ion
dynamics in glassy, crystalline and liquid ionic conductors brought
forth by experiments and simulations are shown to be universal,
i.e. independent of physical and chemical structure of the ionic
conductor as long as ion-ion interaction is the dominant factor.
Moreover these universal properties of ion dynamics are shown to be
isomorphic to other complex interacting systems including the large
class of glass-forming materials with or without ionic
conductivity.By covering the basic concepts, theories/models,
experimental techniques and data, molecular dynamics simulations,
and relating them together, Dynamics of Glassy, Crystalline and
Liquid Ionic Conductors will be of great interest to many in basic
and applied research areas from the broad and diverse communities
of condensed matter physicists, chemists, materials scientists and
engineers. The book also provides the fundamentals for an
introduction to the field and it is written in such a way that can
be used for teaching courses either at the undergraduate or
graduate level in academic institutions.

newcomers to the field of carbon-based electrochemical energy
storage.
The evidence suggests that many solar programs are being designed
and implemented in isolation and without reliance on published
guidelines or the experience gained by others. The conclusion is
obvious: the likelihood of a program being successful would be
greatly improved if program implementers were made more aware of
best practice guidelines and of the lessons and experience learned
by others in implementing previous programs. Furthermore, the best
practice guidelines not only need to be readily available but need
to describe the stages, issues and the stakeholders' roles in
designing and implementing a SHS program. This book showcases a
detailed road map that has been developed for the implementation of
rural electrification projects in developing countries using solar
PV. Features of this book will be case studies derived from
personal participatory observation of the authors on Solar Home
Systems, their impact, their advantages and disadvantages and their
operation.
