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.

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.

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.
The second edition of "Internal Photoemission Spectroscopy" thoroughly updates this vital, practical guide to internal photoemission (IPE) phenomena and measurements. The book's discussion of fundamental physical and technical aspects of IPE spectroscopic applications is supplemented by an extended overview of recent experimental results in swiftly advancing research fields. These include the development of insulating materials for advanced SiMOS technology, metal gate materials, development of heterostructures based on high-mobility semiconductors, and more. Recent results concerning the band structure of important interfaces in novel materials are covered as well. Internal photoemission involves the physics of charge carrier
photoemission from one solid to another, and different
spectroscopic applications of this phenomenon to solid state
heterojunctions. This technique complements conventional external
photoemission spectroscopy by analyzing interfaces separated from
the sample surface by a layer of a different solid or liquid.
Internal photoemission provides the most straightforward, reliable
information regarding the energy spectrum of electron states at
interfaces. At the same time, the method enables the analysis of
heterostructures relevant to modern micro- and nano-electronic
devices as well as new materials involved in their design and
fabrication.

A classic in the area of organic synthesis, "Strategies and
Tactics in Organic Synthesis" provides a forum for investigators to
discuss their approach to the science and art of organic synthesis.
Rather than a simple presentation of data or a secondhand analysis,
we are given stories that vividly demonstrate the power of the
human endeavor known as organic synthesis and the creativity and
tenacity of its practitioners. Firsthand accounts of each project
tell of the excitement of conception, the frustration of failure
and the joy experienced when either rational thought or good
fortune gives rise to the successful completion of a project. This
book series shows how synthesis is really done, and we are
educated, challenged and inspired by these accounts, which portray
the idea that triumphs do not come without challenges. We also
learn that we can meet challenges to further advance the science
and art of organic synthesis, driving it forward to meet the
demands of society, in discovering new reactions, creating new
designs and building molecules with atom and step economies that
provide solutions through function to create a better world.

Foams are ubiquitous in our daily lives. Their presence is highly desirable in certain foods, drinks and cosmetics, and they are essential in oil recovery and mineral extraction. In some industrial processes (such as the manufacture of glass, paper and wine) foams are an unwelcome by-product. Why do they appear? What controls the rate at which they disappear? Do they flow in the same way as ordinary liquids? All of these questions and more are addressed here, incorporating significant recent contributions to the field of foams. This book is the first to provide a thorough description of all aspects of the physico-chemical properties of foams. It sets out what is known about their structure, their stability, and their rheology. Engineers, researchers and students will find descriptions of all the key concepts, illustrated by numerous applications, as well as experiments and exercises for the reader. A solutions manual for lecturers is available via the publisher's web site.

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.
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.
The world is chiral. Most of the molecules in it are chiral, and asymmetric synthesis is an important means by which enantiopure chiral molecules may be obtained for study and sale. Using examples from the literature of asymmetric synthesis, this book presents a detailed analysis of the factors that govern stereoselectivity in organic reactions. After an explanation of the basic physical-organic principles governing stereoselective reactions, the authors provide a detailed, annotated glossary of stereochemical terms. A chapter on "Practical Aspects of Asymmetric Synthesis" provides a critical overview of the most common methods for the preparation of enantiomerically pure compounds, techniques for analysis of stereoisomers using chromatographic, spectroscopic, and chiroptical methods. The authors then present an overview of the most important methods in contemporary asymmetric synthesis organized by reaction type. Thus, there are four chapters on carbon-carbon bond forming reactions, one chapter on reductions, and one on oxidations (carbon-oxygen and carbon-nitrogen bond forming reactions). This organization allows the reader to compare the leading methods for asymmetric synthesis in an appropriate context. A highlight of the book is the presentation and discussion of
transition states at the current level of understanding, for
important reaction types. In addition, extensive tables of examples
are used to give the reader an appreciation for the scope of each
reaction. Finally, leading references are provided to natural
product synthesis that has been accomplished using a given reaction
as a key step.
The Student Solutions Manual provides worked-out solutions to all in-chapter exercises, as well as detailed, step-by-step solutions to odd-numbered practice problems, general problems, and cumulative-skills problems, plus answers to all self-assessment and review questions. Because the Concept Explorations and Strategy Problems are intended to challenge students to think step by step and not rush for a numerical answer (or a matched pair to model an algorithmic answer on), the solutions for these are not provided in the text or Student Solutions Manual. The Student Solutions Manual has been thoroughly accuracy checked for the tenth edition.
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. |
