Nanotechnology can be defined as the science of manipulating matter
at the nanometer scale in order to discover new properties and
possibly produce new products. For the past 30 years, a
considerable amount of scientific interest and R&D funding
devoted to nanotechnology has led to rapid developments in all
areas of science and engineering, including chemistry, materials,
energy, medicine, biotechnology, agriculture, food, electronic
devices, and consumer products. In the U.S. alone, the federal
government has spent more than $22 billion in nanotechnology
research since 2001. The global funding of nanotechnologies was
estimated to be about $7 billion in 2011 and has increased about
20% per year since then, according to various studies. Already some
products have appeared in the marketplace and more will certainly
come in the future. A possible concern is the health, safety, and
environmental impact of some of these products. The U.S. is
certainly investing heavily in nanotechnology. It started the
National Nanotechnology Initiative (NNI) about 16 years ago,
pulling together the efforts of 20 federal departments and
independent agencies. This book contains a wealth of information on
research, product development, commercialization, and regulatory
issues related to nanotechnology.
Nanoscience and nanotechnology have functioned as effective
"buzzwords " for at least a decade due to the unique properties
that materials possess on the nanometer scale. The interest in
nanoscience and nanotechnology is so great and so widespread that
these topics are even being introduced at the K-12 level in some
school districts. Nanoscience and nanotechnology have already
improved many applications and have the potential to continue to do
so, making it important for all types of scientists to stay
up-to-date on research related to nanomaterials. In the first
section of this book, a variety of synthetic methods used to make
or functionalize nanomaterials are presented with work related to
mesoporous materials, semiconductor nanowires, graphene, and carbon
nanotubes included. The second section of the book presents
accounts of using nanotechnology and nanoscience in a variety of
ways. Overall, this book presents a snapshot of research covering
synthetic studies of nanomaterials to applications of
nanomaterials.
Increased energy prices and the growing attention on global warming
are motivating the creation of economically viable alternatives to
fossil fuels. Nanotechnologies have been recognized as one
effective approach to solve energy problems. Therefore, to promote
the improvement of research and to foster professional
collaboration among researchers in energy-related nanotechnologies,
we organized a symposium on "Nanotechnology for a Sustainable
Energy Economy" as a part of the 243rd American Chemical Society
National Meeting, which took place March 25-29, 2012 in San Diego,
California, USA. Forty-four contributors from 12 countries
presented their research works from industrial, university, and
national laboratories in nanotechnology areas related to energy and
fuel technologies. This ACS Symposium Series book was developed
from this symposium. This book presents a very useful and readable
collection of reviews and research papers in nanotechnologies for
energy conversion, storage, and utilization, offering new results
which are sure to be of interest to researchers, students, and
engineers in the field of nanotechnologies and energy. The book
focuses on the following topics: Li batteries (Chapters 1-4),
supercapacitors (Chapter 5), dye-sensitized solar cells (Chapter
6), photocatalysis (Chapters 7-9), fuel cells (Chapter 10),
electrocatalysis (Chapter 11), and electron beam lithography
(Chapter 12). All 12 chapters were recruited from oral
presentations at the symposium.
The conditions of our overpopulated planet with ever-growing energy
needs, fossil fuels in limited supplies, and inefficient energy use
world-wide, are creating a global crisis. Science has a
responsibility, as well as a grand opportunity, to solve these
energy-based problems of society. Science's new nanotechnologies,
and the creativity they bring, are particularly appropriate to
solve these problems. For example, energy-saving lighting, coupled
with improved harvesting and conversion of sunlight into electric
energy, will have a great impact on society's energy needs. Also,
development of energy efficient and low cost fuel cells, which
could eventually replace car engines, has a potential to improve
everyday life greatly. Nanomaterials offer an opportunity to
develop new low-cost materials as environmentally friendly
solutions and renewable energy sources, in order to meet society's
energy needs. Fortunately, a wide spectrum of the scientific
community has become interested in developing these nanomaterials
in order to solve the above energy challenges. Nanomaterials offer
unique mechanical, catalytic, electronic, and optical features,
which are different from those of the analogous bulk material (1).
This is because nanomaterials have scale-dependent properties, due
to quantum size effects, which means the nanomaterial size (10 -
100 nm) is smaller than the mean free path of their electrons.
Thus, nanomaterials have great promise for use in harvesting solar
energy, hydrogen production and storage, fuel cells, catalysis,
chemical, optical sensors, drug delivery systems (such as
liposomes), and nanothermite reactions (2-4). Fluorine-containing
nanomaterials generally have certain unique properties which are
often improved relative to the analogous non-fluorinated
nanomaterials, and which therefore could be engineered. Although
fluorine has the highest electronegativity of all the elements,
which means that bonds to fluorine are generally quite polar, it is
also in the second period of the periodic table, so it also has a
small atomic radius and forms strong bonds. This produces the
following properties, which also are characteristic of and bring
great advantages to fluorine nanomaterials: high thermal and
chemical stability, resistance to degradation by solvents, low
flammability, low moisture absorption, low surface tension or
energy, low dielectric constant, and serving as a strong oxidant
under high energy conditions (5). However, little attention has
been given to fluorine-containing organic and inorganic
nanomaterials, which are predicted to have these unusual
characteristics. This book presents examples of four diverse
classes of these nanomaterials.
