As the global climate changes, scientists anticipate that the distribution of animal populations and disease vectors will expand. In the case of arthropods, such efforts hold immense significance as they have the potential to increase human mortality and suffering from arboviruses above current levels. The 238th American Chemical Society National Meeting and Exposition in Washington, D.C. on August 16-20, 2009, offered an opportunity for researchers to present and discuss new findings in invertebrate repellents research, regulations, and technology development. Recently efforts have been made to understand the role of chemicals in arthropod behavior, and screening programs are starting to incorporate repellency testing into their battery of bioassays. The lack of standardized protocols for measuring and comparison of repellents has remained a significant obstacle in arthropod research. Oftentimes studies report variable measures of success, and comparison of results across studies is not always consistent. Progress in the standardization of arthropod test methods for repellents would be valuable to many groups including academic researchers working in the field, contract labs supplying test results, government research laboratories, regulatory bodies in the process of developing guidelines for product registration, as well as companies looking to invest in new technologies. Perhaps one complicating factor in this process has been that research and technology haven't moved fast enough to meet the demand for effective arthropod repellents. Issues such as pest arthropod resurgence and insecticide/repellent resistance to chemical can create new challenges and add pressure for researchers. The collection of chapters in this book covers a range of applied and basic research on arthropod repellents. An overview of the state of arthropod repellents research is provided at the start. In the chapters that follow, there is a selection of papers demonstrating research on new repellent technologies at different stages of development. The scope of basic and applied research methods described in these chapters on new repellent technologies presents the range of testing that is often necessary to move a repellent technology forward in development. The transition from newly developed technologies to registered products is achieved in perspective of a growing market for natural arthropod repellents. New technologies that are completely developed and have gone through registration need to be accompanied by successful commercialization. The growing market for natural arthropod repellents presents such an example and highlights new opportunities in this area. The concluding chapter discusses the public entomology landscape, past and future opportunities for the development of chemical protectants.
This book describes the profound changes that occurred in the teaching of chemistry in western countries in the years immediately following the Soviet Union's launch of Sputnik, the first artificial Earth satellite, in 1957. With substantial government and private funding, chemistry educators introduced new curricula, developed programs to enhance the knowledge and skills of chemistry teachers, conceived of new models for managing chemistry education, and experimented with a plethora of materials for visualization of concepts and delivery of content. They also began to seriously study and apply findings from the behavioral sciences to the teaching and learning of chemistry. Now, many chemistry educators are contributing original research in the cognitive sciences that relates to chemistry education. While Sputnik seemed to signal the dawn of far-reaching effects that would take place in political, diplomatic, and strategic, as well as in educational spheres, the seeds of these changes were sown decades before, mainly through the insight and actions of one individual, Neil Gordon, who, virtually singlehandedly, launched the ACS Division of Chemical Education and the Journal of Chemical Education. These two institutions provided the impetus for the United States to eventually become the undisputed leader in chemistry education worldwide.

understand and utilize these fundamental reactions in their work,
including brief practical details. The book is illustrated with
real synthetic examples from the literature and about 3,400
references to the primary literature to aid further reading.
Extensive indexes (name, reagent, reaction) and a very useful
functional group transformation index help the reader fully
navigate this extensive collection of important reactions. With its
comprehensive coverage, superb organization and quality of
presentation, this long-awaited new edition belongs on the shelf of
every organic chemist.
This book makes a serious effort at bringing forth and synergistically combining the concepts of green chemistry, sustainability and nanotechnology and should motivate scientistsat all levels to think clearly and seriously about creating and optimizing novel and sustainable green approaches to nanotechnology. The chapters in this book can be divided into three broad categories: 1) Advancement in research on pollution control through the green chemistry principles of nanotechnology; 2) Emergence of nanomaterials in widespread applications in various scientific fields, including but not limited to sensors and catalysts; 3) Extension of research into nanotechnology and green nanotechnology at a rapid pace. Review articles on the individual aspects of these diverse and complementary topics have become important resources for researchers, industry leaders, and regulators, both nationally and internationally. This book contains a few chapters associated with these particular themes, and provides glimpses of the many difficulties and challenges faced by those who seek to not only understand but also regulate the new nanomaterials. Nanotechnology represents a unique field of science, and necessitates new and novel sustainable approaches to create usable end products for the market place with the primary goal of yielding less adverse effects upon both human health and the environment.
Compelling evidence exists to support the hypothesis that both
formal and informal mentoring practices that provide access to
information and resources are effective in promoting career
advancement, especially for women. Such associations provide
opportunities to improve the status, effectiveness, and visibility
of a faculty member via introductions to new colleagues, knowledge
of information about the organizational system, and awareness of
innovative projects and new challenges.
This book, based primarily on late breaking work ... provides an
interesting snapshot at some of the main lines of current and new
research within the field, such as investigation of the novel
properties of ionic liquids and their uses in separations (e.g.,
gases, organics, and metal ions), biochemistry, medicine, and
nanochemistry. The chapters also reflect the growing theoretical
and computational work within the field leading to new predictive
capability.
This book discusses the combined fields of Intellection Property
and Information Science. At this crossroads of these two
disciplines are lawyers, educators, intellectual property
specialists, searchers, librarians, and consultants, each requiring
a lengthy list of skills necessary for the job. The results of the
work they do is used for business and legal decisions across many
sectors of our society, including industry, academia, government,
and non-profits, to name a few. This book originated from the
American Chemical Society (ACS) Symposium entitled "IP to IP:
Intellection Property for Information Professionals," presented in
Washington DC on August 19th, 2009. It was organized to highlight
the specialty training and education required to work in this
field. The book is targeted towards Information Scientists learning
about Intellectual Property. Traditional education sources such as
universities are represented, and are specialty offerings from the
pharmaceutical sector and the United States Patent and Trademark
Office (USPTO).
There are eight columns in the Periodic Table. The eighth column is
comprised of the rare gases, so-called because they are the rarest
elements on earth. They are also called the inert or noble gases
because, like nobility, they do no work. They are colorless,
odorless, invisible gases which do not react with anything, and
were thought to be unimportant until the early 1960s. Starting in
that era, David Fisher has spent roughly fifty years doing research
on these gases, publishing nearly a hundred papers in the
scientific journals, applying them to problems in geophysics and
cosmochemistry, and learning how other scientists have utilized
them to change our ideas about the universe, the sun, and our own
planet.
"Progress in Medicinal Chemistry" provides a review of eclectic developments in medicinal chemistry. This volume continues in the serial's tradition of providing an insight into the skills required of the modern medicinal chemist; in particular, the use of an appropriate selection of the wide range of tools now available to solve key scientific problems, including g-secretase modulators, P2X7 antagonists as therapeutic agents for CNS disorders, N-type calcium channel modulators for the treatment of pain, and more.
This book examines the history and fundamentals of the physical organic chemistry discipline. With the recent flowering of the organic synthesis field, physical organic chemistry has seemed to be shrinking or perhaps is just being absorbed into the toolkit of the synthetic chemist. The only Nobel Prize that can be reasonably attributed to a physical organic chemist is the 1994 award to George Olah, although Jeffrey I. Seeman has recently made a strong case that R. B. Woodward was actually a physical organic chemist in disguise (I). 2014 saw the awarding of the 50th James Flack Norris Award in Physical Organic Chemistry. James Flack Norris was an early physical organic chemist, before the discipline received its name. This book provides insight into the fundamentals of the field, and each chapter is devoted to a major discovery or to noted physical organic chemists, including Paul Schleyer, William Doering, and Glen A. Russell.

This book is focused on recent progress in the dynamically developing field of controlled/living radical polymerization. It is a sequel to ACS Symposium Series 685, 768, 854, and 944. The volume contains 24 chapters on other controlled/living radical polymerization techniques including kinetics and mechanism of RAFT, DT, NMP, and OMRP, macromolecular architecture by RAFT, DT, and NMP, materials prepared by RAFT and NMP, and industriral aspects of RAFT and NMP.
Collaborations between scientists often transcend borders and cultural differences. The fundamental nature of science allows scientists to communicate using knowledge of their field but the institutions that support them are often hindered by financial and cultural barriers. As a result, science suffers. This book evolved from an August 2009 symposium at the 238th annual meeting of the American Chemical Society in Washington, DC. Its focus is on chemistry students and professors interested in developing a global approach to teaching chemistry, by participating in an international exchange program or incorporating culturally inclusive techniques into their classroom. The book has three broad themes; education research with a globalized perspective, experiences of teaching and learning in different countries, and organizations that support a global view of chemical education and chemistry.

Dr. Marie Maynard Daly received her PhD in Chemistry from Columbia
University in 1947. Although she was hardly the first of her race
and gender to engage in the field, she was the first African
American woman to receive a PhD in chemistry in the United States.
In this book, Jeannette Brown, an African American woman chemist
herself, will present a wide-ranging historical introduction to the
relatively new presence of African American women in the field of
chemistry. It will detail their struggles to obtain an education
and their efforts to succeed in a field in which there were few
African American men, much less African American women.

This book will provide valuable insight and information to all teachers of physical chemistry.
Levels of mycotoxin contamination in agricultural commodities are
regulated in more than 100 countries, and exposure to these
naturally occurring toxins presents serious risks to the health of
humans and animals with negative impacts to commodity values. This
symposium series book presents significant scientific developments
in the multifaceted approach to reducing exposure to these
naturally occurring toxins. A broad-spectrum of subject matter of
the multidisciplinary field of mycotoxin research is conveniently
compiled in this single volume, and general themes include
prevention, control, exposure, molecular biology, biosynthesis,
analytical methodology, and emerging techniques. The book opens
with an overview of prevention of mycotoxin production by means of
biological control and human exposure to contaminated foods,
including tofu, apples, figs, and a broad range of fruits.
This title in the authoritative Interface Science and Technology
Series presents the key features and applications of modified oxide
and phosphate surfaces.
As the cleanest source of fossil energy with the most advantageous
CO2 footprint, natural gas continues to increase its share in the
global energy market. This book provides state-of-the-art
contributions in the area of gas processing. Special emphasis is
given to Liquified Natural Gas (LNG); the book also covers the
following gas processing applications in parallel sessions:
This book treats the different current as well as unusual and
hitherto often unstudied physico-chemical and surface-thermodynamic
properties of water that govern all polar interactions occurring in
it. These properties include the hyper-hydrophobicity of the
water-air interface, the cluster formation of water molecules in
the liquid state and the concomitant variability of the ratio of
the electron-accepticity to electron-donicity of liquid water as a
function of temperature, T. The increase of that ratio with T is
the cause of the increase in hydration repulsion ("hydration
pressure") between polar surfaces upon heating, when they are
immersed in water.
Aggregation-induced emission (AIE) stands for an intriguing phenomenon in which a series of non-emissive molecules in solutions are induced to emit strongly in the aggregate or solid state. The concept of AIE was first coined by author Ben Zhong Tang in 2001, when he and his co-workers serendipitously discovered that 1-methyl-1,2,3,4,5-pentaphenylsilole was almost non-emissive in ethanol solution but became extremely bright in water-ethanol mixtures. Over the past 15 years, AIE has grown into a research field with high visibility and broad impact across both science and technology. Aggregation-Induced Emission: Materials and Applications summarizes the recent advances in AIE research, ranging from fundamentals, such as design, synthesis, and optical properties of AIE-active molecules, to mechanism studies supported by modeling and experimental investigations, and further to promising applications in the fields of energy, environment, and biology. The topics covered in Volume 2 include: AIE polymers; AIE-induced chirogenesis; Room-temperature phosphorescent AIE molecules; Liquid crystalline AIE molecules; AIE materials for energy devices; New chemo- and biosensors with AIE molecules; Cell structure and function imaging with AIE molecules; and AIE materials in drug delivery and therapy.
Nuclear magnetic resonance (NMR) is an analytical tool used by
chemists and physicists to study the structure and dynamics of
molecules. In recent years, no other technique has grown to such
importance as NMR spectroscopy. It is used in all branches of
science when precise structural determination is required and when
the nature of interactions and reactions in solution is being
studied. "Annual Reports on NMR Spectroscopy" has established
itself as a premier means for the specialist and non-specialist
alike to become familiar with new techniques and applications of
NMR spectroscopy.
Cryogenics is the study of low temperature interactions -
temperatures well below those existing in the natural universe.

Advances in Planar Lipid Bilayers and Liposomes, Volume 6,
continues to include invited chapters on a broad range of topics,
covering both main arrangements of the reconstituted system, namely
planar lipid bilayers and spherical liposomes. The invited authors
present the latest results in this exciting multidisciplinary field
of their own research group.
Chirality as an environmental phenomenon was dealt with in a
thorough and interesting manner in a series of three symposia
entitled "Modern Chiral Pesticides: Enantioselectivity and Its
Consequences," sponsored by the Agrochemical Division of the
American Chemical Society and held in Washington, DC (2005),
Boston, MA (2007) and San Francisco, CA (2010). All three symposia
included speakers from industry, government and academia,
representing several European countries, China, and the United
States. Corresponding to this broad group of countries,
institutions and speakers, the range of topics touched on almost
all facets of chirality as it is manifested in environmental and
human exposure and toxicity. The 40 oral and 20 poster
presentations indeed approached comprehensive coverage: analysis of
enantiomers and other stereoisomers; preparative separation of
enantiomers; stereoselective occurrences of chiral pesticides in
environment soil and water and in wildlife and human tissues and
fluids; stereoselective degradation and metabolism of chiral
pesticides; and stereoselective toxicity. |
