The identification and quantification of the widespread occurrence of trace organic chemicals at minute concentrations in the aqueous environment impacted by human activities is a result of rapid advances in environmental analytical chemistry. The body of knowledge regarding the characterization, fate and transport of these chemicals of emerging concern (CECs) in the natural water environment and engineered water treatment processes, as well as their toxicity, has grown substantially over the last two decades. Recently, the focus in the environmental chemistry community has shifted from these CEC parent compounds to the fate, transport, and toxicity of transformation products, which are generated through abiotic and biotic mechanisms in natural systems and during engineered advanced water treatment processes. This two-part book focuses on the studies and recent advancements towards the development of more harmonized strategies and workflows using non-target and suspects screening methods, including suitable bioassay approaches to assess the overall relevance of transformation products. Volume I covers the relevance of transformation products and international strategies to manage CECs, new methods for a comprehensive assessment of transformation products, and the fate and transport of transformation products in natural systems. This book is ideal for environmental scientists and engineers, particularly chemists, environmental engineers, public health officials, regulators, other chemistry-related professionals, and students.

""This book should become an indispensable asset on the bookshelves of pharmaceutical laboratories in academia and in industry, as well as of laboratories devoted to plant protection. I am convinced that studying this book will be an eye-opener for many scientists in the field of life sciences. Furthermore, for teachers in this area it will not only be a useful compilation of the various languages and definitions of organic stereochemistry, but also a welcome source of examples for demonstrating to their students the intricate and intriguing role stereochemistry plays in the chemistry of life."" -Prof. Dr. Dieter Seebach, Laboratory of Organic Chemistry, ETH Zurich, Switzerland This textbook presents the molecular scale of matter in the broad diversity and richness of its three dimensions, giving due attention when relevant to the temporal dimension in which molecules exist, act, and react. The focus is on two significant fields of three-dimensional chemistry: a presentation of the guiding principles in organic stereochemistry, followed by a focus on the biochemical and medicinal relevance of this discipline. The treatment of "Guiding Principles "gives priority to didactic clarity and nomenclature issues, as detailed and illustrated in Parts 1 to 4: '"Symmetry Elements and Operations, Classification of Stereoisomers"''"Stereoisomerism Resulting from One or Several Stereogenic Centers"''"Other Stereogenic Elements: Axes of Chirality, Planes of Chirality, Helicity, and ("E," "Z")-Diastereoisomerism"''"Isomerisms about Single Bonds and in Cyclic Systems"' This is followed by Parts 5 to 8 which focus on the biomedicinal relevance of stereochemistry, with special reference to the biochemistry and pharmacology of medicinal compounds. Here, examples and applications are discussed and illustrated based on their relevance to a given specific stereochemical aspect: '"Chirality in Molecular and Clinical Pharmacology"''"The Conformational Factor in Molecular Pharmacology"''"The Concept of Substrate Stereoselectivity in Biochemistry and Xenobiotic Metabolism"''"Prostereoisomerism and the Concept of Product Stereoselectivity in Xenobiotic Metabolism"' Finally, the book contains a gift for broad-minded readers with an interest in the historical roots of stereochemistry: Part 9: '"Molecular Chirality in Chemistry and Biology: Historical Milestones"' Key features: Consists entirely of beautifully produced colored figuresIncludes marginal notes, giving clear-cut short definitions of terms used in the corresponding captionProvides an alphabetic glossary of termsOffers an extensive index
Manganese (Mn) oxides are among the most reactive minerals in the earth's surface environment, and play a significant role in adsorption, co-precipitation and redox reactions, affecting biogeochemical cycles of numerous nutrients and contaminants. In addition, manganese oxides are widely applied as absorbents, ion sieves, chemical oxidants and catalysts for environmental remediation and pollution control. There are, however, still many aspects poorly understood in terms of the environmental geochemistry of manganese oxides, such as biogenic formation mechanisms, detailed crystal structure of nanocrystalline phases, electron transfer paths in redox reactions, adsorption mechanisms of contaminants on surfaces, physiochemical factors controlling the contents of structural Mn(III) and vacant sites that largely determine Mn oxide reactivity, and the role of Mn(III) in the above processes. This book aims to bring together advances on manganese oxide environmental biogeochemistry from leading scientists in multiple disciplines, e.g., mineralogy, geochemistry, soil science and environmental engineering. A number of frontier research topics are included in the book, such as in-situ characterization of Mn oxide reactivity with As and Cr, kinetics and molecular-scale mechanisms of metal oxidation by mangnese oxides, mechanistic understanding of metal sorption through density function theory, the role of surface edge sites of birnessites in metal(loid) sorption, reactivity of natural crytomelane, pathways of phyllomanganate transformation to todorokite, water-oxidation catalysis by manganese oxides, in situ As immobilization using stabilized Fe-Mn binary oxides, and synthesis of Li ion-sieves from biogenic oxides and stability of colloidal Mn oxides. The book should be of interest to scientists and engineers in a broad range of disciplines, such as geochemistry, soil science, mineralogy, microbiology, materials science, and environment engineering, as well as graduate students who are engaged in research on manganese oxide biogeochemistry and the engineering application of Mn-bearing materials.
In the past few years, the subject of climate change has frequently garnered headlines due to the usual political controversy surrounding it. However, setting aside the argument as to whether climate change is a man-made effect or not, we cannot deny the fact that humanity has been discharging carbon increasingly into the atmosphere for centuries. Likewise, similar reports on the growing Great Pacific Garbage Patch-and the general accumulation of plastics everywhere-are alarming. Moreover, it has also been recently demonstrated that microplastics are finally entering the food webs which include the human consumer. Air, soil, and water pollution are increasing; in some ways forcing certain countries and governments to modify their politics, while also creating new opportunities and opening new niches for the marketing of products, such as air and water filters. With current techniques, it is not possible to completely eliminate all toxic and hazardous waste, which means that security deposits are necessary. Security deposits are storage areas prepared for certain toxic and dangerous industrial waste, so that its harmful properties cannot affect the natural environment and human health-at least, in any case, for a very long time. Due to their geomorphological composition, topography, and hydrographic conditions, there are sites that can be used as waste deposits, given their natural isolation and projected stability for hundreds of years. Thus, they become security deposits. In addition, every day new materials and construction techniques are developed that allow for a total isolation of the waste. A relatively new view in the material life cycle is the reuse of the generated waste as new resources. This helps to mitigate the cost increases in raw materials, energy, and regulations regarding waste disposal, which have caused the industry to rethink its production methods, leading to a better use of raw materials and energy. Clean technologies are those used by the industry to reduce the need for treatment or disposal of waste and to reduce the demand for raw materials, energy, and water. For the proper implementation of clean technologies, industries and municipalities must develop a deep understanding of their own processes and activities, and must analyze the characteristics of their equipment and make any possible modifications. An environmental evaluation of the situation provides suitable information on the efficiency of each component and its integration in the whole process, on the proportion of waste, on energy consumption, and on how to reorganize or modify to improve cost-efficiency in economic and environmental terms, which in a middle term view results in synergistic goals. With this concise introduction to the world of waste and pollutant treatment technologies, the editors believe it is clear that the solutions are to be developed on a case-by-case basis; because the larger the number of mixed pollutants, the more complex and intimated the process will be. This book presents a series of selected approaches that can be used to approach different cases, also depending upon budget and viability of a sustainable approach. This book serves as a source of information, triggers ideas, and fosters interaction between all the players taking action in sustainable development initiatives.
The latest edition of Animal Nutrition has been updated thoroughly to provide a clear and comprehensive introduction to the science and practice of animal nutrition. This classic, market-leading text is a trusted resource for undergraduates studying Animal Science, Veterinary Science, Agriculture, Biology and Biochemistry. It is supported by key experimental evidence throughout about modern advancements in animal food nourishment, composition of foods and feeding standards for dairy and beef cattle, sheep, pigs and poultry, horses, and cats and dogs. It is split into six main sections covering: The components of food; The digestion and metabolism of nutrients; Quantifying the nutrient content of foods: digestibility, energy and protein values; The nutrient requirements of animals; The nutritional characteristics of foods; and Animal products and human nutrition. Quantitative aspects of the subject are clearly explained and illustrated by worked examples. Problems have been added to all chapters to aid student learning and the appendices include solutions to all chapter-end numeric questions. This edition includes nutritional topics related to molecular biology, the environment, and companion animals - dog and cat nutrition has been expanded. Under nutrient requirements of animals, usage of novel foods such as insects has also been added. Chapter-end summaries and questions allow students to recap and test their knowledge of the chapter topic.
Information literacy-the ability to find, evaluate, and use information resources-is an important skill for future chemists. Students and scientists need to distinguish between information provided by Wikipedia, ChemSpider, research journals, and The New York Times, depending on the intended use of the information sought. Instructors and librarians may often teach these skills through stand-alone database demonstrations, video tutorials, and lectures. However, it is possible to teach these skills in a more contextual and integrated manner by designing chemistry assignments that incorporate information literacy as a learning outcome. This book will prove useful for librarians and chemistry instructors who are designing courses in which students develop information literacy in the context of a chemistry course at two-year colleges, public and private universities, and high schools. The chapters in this book review the current state of information literacy in chemistry and provide concrete examples of assignments and interventions aimed at teaching information literacy skills in chemistry curricula. A wide range of options are offered for integrating information literacy into college-level chemistry courses, including general chemistry, organic chemistry, science courses for students not majoring in science, and chemistry capstone research courses.
Artificial intelligence is smarter than humans. It can process information at lightning speed and remain focused on specific tasks without distraction. AI can see into the future, predict outcomes and even use sensors to see around physical and virtual corners. So why does AI frequently get it so wrong and cause harm? The answer is us: the human beings who write the code and teach AI to mimic our behaviour. Scary Smart explains how to fix the current trajectory now, to make sure that the AI of the future can preserve our species. This book offers a blueprint, pointing the way to what we can do to safeguard ourselves, those we love and the planet itself.
Engineering is mathematics in action. But engineering students do not always see the link between what they learn in mathematics and how this applies to engineering problems. From relatively simple questions, like determining the maximum weight a beam can support to complex projects like mapping out the most efficient electrical flow for a city’s traffic lights, mathematics is essential.
Even the most cursory survey of the chemical literature reveals that modern NMR spectroscopy has indeed fulfilled its potential as a powerful and indispensable tool for probing molecular structure, providing detail that is comparable to, and sometimes surpasses that, of X-ray crystallography. As NMR spectroscopy's 70th anniversary approaches, the diversity of chemical problems to which this technique can be applied continues to grow across many scientific fields. Beyond the laboratory setting, the technology underlying NMR is now a widely used and critical medical diagnostic technique, Magnetic Resonance Imaging (MRI). Unfortunately, the number of applications of NMR spectroscopy across so many STEM-related fields presents significant challenges in how best to introduce this powerful technique in meaningful ways at the undergraduate level. Inspired by the development of the field, and building upon the work of previous symposia and an ACS symposium series book on this topic (3), a symposium was developed, entitled "NMR Spectroscopy in the Undergraduate Curriculum," for the 239th American Chemical Society National Meeting in San Francisco. This book brings together all of the presenters who have been successful in developing and successfully integrating NMR spectroscopy pedagogy across their undergraduate curriculums. Their knowledge and experiences will aid readers who are interested in expanding and invigorating their own curriculum.

Now more than ever we are facing pressing world challenges of energy (identifying alternate energy), food (ensuring the food supply), water (providing clean water), and human health (enabling individualized medicine); and to solve these challenges will require chemistry and the related chemical sciences. Integrating sustainability into everything we do from instituting responsible operations, to selecting partners for change and innovating sustainable solutions. Industry needs academe to prepare their graduates to ascend the ladder with skill and agility. This can only be done by integrating sustainability expeditiously into chemistry curricula.
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.
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 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 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.
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).
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.
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.
A bold, provocative exploration of the tension between our evolutionary history and our modern woes - and what we can do about it We are living through the most prosperous age in all of human history, yet we are listless, divided and miserable. Wealth and comfort are unparalleled, but our political landscape is unmoored, and rates of suicide, loneliness and chronic illness continue to skyrocket. How do we explain the gap between these truths? And how should we respond? For evolutionary biologists Heather Heying and Bret Weinstein, the cause of our woes is clear: the modern world is out of sync with our ancient brains and bodies. We evolved to live in clans, but today many people don't even know their neighbours' names. Survival in our earliest societies depended on living in harmony with nature, but today the food we eat, the work we do - even the light we absorb - is radically different from what our minds and bodies evolved to expect. In this book, Heying and Weinstein draw on decades of their work teaching in college classrooms and exploring earth's most biodiverse ecosystems to confront today's pressing social ills - from widespread sleep deprivation and dangerous diets to damaging parenting styles and backward education practices. A Hunter-Gatherer's Guide to the 21st Century outlines a science-based worldview that will empower you to live a better, wiser life.
Homework help! Develop the solid problem-solving strategies you need for success in organic chemistry with this Study Guide/Solutions Manual. Contains answers to all problems in the text.
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. |
