With nanotechnology being a relatively new field, the questions
regarding safety and ethics are steadily increasing with the
development of the research. This book aims to give an overview on
the ethics associated with employing nanoscience for products with
everyday applications. The risks as well as the regulations are
discussed, and an outlook for the future of nanoscience on a
manufacturer's scale and for the society is provided. Ethics in
nanotechnology is a valuable resource for, philosophers,
academicians and scientist, as well as all other industry
professionals and researchers who interact with emerging social and
philosophical ethical issues on routine bases. It is especially for
deep learners who are enthusiastic to apprehend the challenges
related to nanotechnology and ethics in philosophical and social
education. This book presents an overview of new and emerging
nanotechnologies and their societal and ethical implications. It is
meant for students, academics, scientists, engineers, policy
makers, ethicist, philosophers and all stakeholders involved in the
development and use of nanotechnology.
The 6th volume of Green Chemical Processing considers sustainable
chemistry in the context of innovative and emerging technologies,
explaining how they can support the "greening" of industry
processes. 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.
With the fast pace of developments in quantum technologies, it is
more than ever necessary to make the new generation of students in
science and engineering familiar with the key ideas behind such
disruptive systems. This book intends to fill such a gap between
experts and non-experts in the field by providing the reader with
the basic tools needed to understand the latest developments in
quantum communications and its future directions. This is not only
to expand the audience knowledge but also to attract new talents to
this flourishing field. To that end, the book as a whole does not
delve into much detail and most often suffices to provide some
insight into the problem in hand. The primary users of the book
will then be students in science and engineering in their final
year of undergraduate studies or early years of their post-graduate
programmes.
This volume is devoted to mostly to nanotubes, unique synthetic
nanoscale quantum systems whose physical properties are often
singular (i.e. record-setting). Nanotubes can be formed from a
myriad of atomic or molecular species, the only requirement
apparently being that the host material or "wall fabric" be
configurable as a layered or sheet-like structure. Nanotubes with
sp2-bonded atoms such as carbon, or boron together with nitrogen,
are the champions of extreme mechanical strength, electrical
response (either highly conducting or highly insulating), and
thermal conductance. Carbon nanotubes can be easily produced by a
variety of synthesis techniques, and for this reason they are the
most studied nanotubes, both experimentally and theoretically.
Boron nitride nanotubes are much more difficult to produce and only
limited experimental characterization data exist. Indeed, for boron
nitride nanotubes, theory is well ahead of experiment. For these
reasons this volume deals largely with carbon nanotubes.
Conceptually, the "building block" for a carbon nanotube is a
single sheet of graphite, called graphene. Recently, it has become
possible to experimentally isolate such single sheets (either on a
substrate or suspended). This capability has in turn fueled many
new theoretical and experimental studies of graphene itself. It is
therefore fitting that this volume contains also a chapter devoted
to graphene.

Today engineers, designers, buyers and all those who have to work
with plastics face a dilemma. There has been a proliferation of
test methods by which plastic properties are measured. The property
data measured by these test methods are not identical and sometimes
have large differences. How are engineers, designers, buyers going
to decide the type and resin grade and their property data? Which
are the valid test methods? The right plastic property data are the
difference between success and failure of a design, thus making the
property selection process critical. For the first time this book
provides a simple and efficient approach to a highly complex and
time consuming task. There are over 26,000 different grades of
polymers and millions of parts and applications, further adding to
the difficulty of the selection process.
Selection of Polymeric Materials steers engineers and designers
onto the right path to selecting the appropriate values for each
plastic property. A large amount of property information has been
provided to teach and assist the plastic part designer and others
in selecting the right resin and properties for an application.
Various standards including ASTM, ISO, UL, and British
Specifications have been discussed to help the readers in making
sound decisions.
A simple and efficient approach to a highly complex and time
consuming task.
Allows engineers to select from various standards including ASTM,
ISO, UL, and British Specification.
Presents information on properties such as tensile strength, melt
temperature, continuous service temperature, moisture exposure,
specific gravity and flammability ratings.
Tried and true values narrow myriad choices down quickly for
readers."

Theoretical and practical interests in additive manufacturing (3D
printing) are growing rapidly. Engineers and engineering companies
now use 3D printing to make prototypes of products before going for
full production. In an educational setting faculty, researchers,
and students leverage 3D printing to enhance project-related
products. Additive Manufacturing Handbook focuses on product design
for the defense industry, which affects virtually every other
industry. Thus, the handbook provides a wide range of benefits to
all segments of business, industry, and government. Manufacturing
has undergone a major advancement and technology shift in recent
years.

Critical Materials takes a case-study approach, describing
materials supply-chain failures from the bronze age to present day.
It looks at why these failures occurred, what the consequences
were, and how they were resolved. It identifies key lessons to
guide responses to current and anticipated materials shortages at a
time when the world's growing middle class is creating
unprecedented demand for manufactured products and the increasingly
exotic materials that go into them. This book serves as a guide to
materials researchers and industrial end-users for finding
effective approaches to shortages of specialty materials. The
lessons in the book are also appropriate to those who use materials
and for those involved in manufacturing supply-chain management and
industrial design.
Conducting polymers were discovered in 1970s in Japan. Since this
discovery, there has been a steady flow of new ideas, new
understanding, new conducing polymer (organics) structures and

devices. Almost all properties, mechanical, electrical, and
optical, are important in organics. This book describes the recent
advances in these organic materials and devices.

platforms for oral drug administration are discussed. The relevance
of controlling the physicochemical properties of the developed
particle formulations, from size and shape to drug release profile
are broadly reviewed. Advances in both in vitro and in vivo
scenarios are discussed, focusing on the possibilities to study the
biological-material interface. The industrial perspective on the
production of nanotechnology-based oral drug delivery systems is
also covered. Nanotechnology for Oral Drug Delivery: From Concept
to Applications is essential reading for researchers, professors,
advanced students and industry professionals working in the
