Nuts and Bolts of Chemical Education Research is book that would be useful for the chemist who is writing the educational outreach or evaluation component of a grant or planning his own chemical education research project. This book brings to the surface the key elements that are common to both. These key elements include establishing clear goals and research questions for your efforts: placing your outreach or research on a firm theoretical foundation so that the results of your work expand the current state of knowledge; developing an outreach or research design that address the goals and questions asked; locating, developing and testing the validity-reliability of the tools used in the study; selecting appropriate data analyses from quantitative, qualitative or mixed design disciplines to address the questions asked; writing conclusions based upon the data presented; and describing the implications of the outreach or research effort for chemistry practitioners. This book will address these key issues from a pragmatic point of view in an effort to assist those who are engaged or considering becoming engaged in this type of scholarly activity.

Green Chemistry - a new approach to designing chemicals and chemical transformations that are beneficial for human health and the environment - is an area that continues to emerge as an important field of study. Practitioners design to be more sustainable the materials, products, and processes that are the basis of our technologically advanced society and economy. Molecular designers are seeing new performance capabilities in the products, new efficiencies in the processes, and achievements in meeting the goals for protecting human health and the environment in a profitable way. Educators have recognized that Green Chemistry principles and practice have not been a part of traditional training in chemistry, and are not part of the skill sets of most practicing chemists. Leaders in Green Chemistry education have developed a wide range of new approaches, courses, tools, and materials that have been introduced and demonstrated in the chemistry curriculum in colleges and universities around the U.S. This ACS Symposium Series Book collects the current research and advances in the field of green chemistry, with an emphasis on providing educators with the knowledge and tools needed to incorporate recent information about this field into the chemistry curriculum. This volume is an outstanding resource for any chemical educator wishing to deepen, broaden, or begin the inclusion of green principles and practices into their teaching or research. Given the current interest in green chemistry, this timely book provides an invaluable snapshot of green chemistry education, highlighting best practices from the first decade of greening the chemistry curriculum.

Chemical education is essential to everybody because it deals with ideas that play major roles in personal, social, and economic decisions. This book is based on three principles: that all aspects of chemical education should be associated with research; that the development of opportunities for chemical education should be both a continuous process and be linked to research; and that the professional development of all those associated with chemical education should make extensive and diverse use of that research. It is intended for: pre-service and practising chemistry teachers and lecturers; chemistry teacher educators; chemical education researchers; the designers and managers of formal chemical curricula; informal chemical educators; authors of textbooks and curriculum support materials; practising chemists and chemical technologists. It addresses: the relation between chemistry and chemical education; curricula for chemical education; teaching and learning about chemical compounds and chemical change; the development of teachers; the development of chemical education as a field of enquiry. This is mainly done in respect of the full range of formal education contexts (schools, universities, vocational colleges) but also in respect of informal education contexts (books, science centres and museums).

College and university faculty find themselves tasked with teaching in the face of ever-changing trends in higher education and constant shifts in the student population. Educators must balance student engagement and retention with their learning and satisfaction in a never-ending cycle of changes in technology, the economy, and the political climate. Even when certain pedagogies or classroom techniques are shown to be beneficial in one discipline, individual faculty may find it challenging to apply them in their own classrooms. This is certainly true in chemistry. Many faculty in chemistry today struggle to embrace research-based educational practices, even those coming out of our own discipline. Graduate programs in chemical education, recent reports on discipline-based education research (1), and an increase in the scholarship of teaching and learning in chemistry indicate a desire among many faculty to change-to reach students in new and exciting ways or to change curricula to better meet students' needs. Faculty are looking for things that work-techniques used by chemists, for chemists. This volume contributes to this on-going conversation. The scholarship presented within this volume is organized in three sections. The first explores innovations found to enhance the learning of typical students as well as those who may be under-prepared. Authors describe their experiences using the flipped classroom and institutional readiness models. The second section provides examples of how technology may be utilized in the chemistry classroom-from e-textbook usage to a computational chemistry program to concrete suggestions for teaching chemistry online. The final section addresses broader issues in chemistry. One chapter demonstrates how to incorporate High-Impact Educational Practices (2) into courses for chemistry majors and nonmajors. A final chapter describes how colleges can adopt the Green Chemistry Commitment. Additionally, contextual information for pedagogical change may be found in the Introduction as well as helpful tips for adopting new approaches.

The American Chemical Society Symposium book African Natural Plant Products was originally conceived as a vehicle to present scientific discoveries, challenges, and to create a dialogue focused on African natural products, an area still very underexplored as a vehicle to benefit the African people. And yet, scientists realized early on the remarkable diversity and range of African plants and products being used for a wide variety of applications (foods, flavorings, medicine, nutrition and health). This series is to provide a scientific stimulus for greater research, enhanced collaboration, and confirmation and/or validation on the uses and importance of African natural plant products, particularly those steeped in a rich traditional history. The Volume II "Discoveries and Challenges in Chemistry, Health and Nutrition" is a new installment of an international effort to provide a communication platform for scientists to share their interest in African plants and products. The book seeks to promote the identification of new uses and applications that can contribute to the development of the African continent, as the value of plant uses emerges from the interaction of the rich biodiversity of the African ecosystems with societies and cultures. The focus will expand to include health and nutritional considerations in addition to the core natural product chemistry and continue to present new findings.

Free Radicals in Food: Chemistry, Nutrition, and Health presents recent developments in free radical chemistry as it pertains to food systems, antioxidants, and nutritional biochemistry and health. This book intends to illustrate the potential chemical links between food and health. The book is organized into three main sections: Food Chemistry, Antioxidants, and Nutritional Biochemistry and Health. Chapters in the Food Chemistry section cover free radical participation in Maillard reactions, emulsions and lysozymes, milk, meat, and extruded grains. This section also addresses detection of radicals by ESR and spin trapping techniques. Chapters in the Antioxidant section cover phenolic and polyphenols from seeds and tea, tannins, and isoflavonoids. Chapters in the Nutritional Biochemistry and Health section cover the influence of food antioxidants and radical damaged ingredients on oxidases, colon carinogenesis, atherosclerosis, and liver epithelial RL34 cells. The ability of specific food components and supplements to intervene in free radical reactions is believed to play a significant role in their ability to promote health and ameliorate disease. Free Radicals in Food presents specific chemical evidence to support these hypotheses.

Sweetness is the major vehicle through which we accept or dislike many food products. Sugar has the disadvantage of being associated with a number of adverse health related issues and as a result, myriad hours are spent producing non-caloric sweeteners to mimic sugar. The discovery of the taste receptors and the recent breakthrough in the culturing of taste bud cells have heightened the field of Sweeteners and modified our perception of them. This book will examine this closely. The proposed book will also follow the symposium closely discussing some of the following: Structural Studies of the Sweetener Receptor, Modeling of the Sweetener Receptor, Sweet Taste Transduction, and Advances in the Discovery and Commercial Development of Natural Non-Caloric Sweeteners.

Microreaction technology, with its unprecedented heat and mass transfer advantages as well as uniform residence time and flow pattern, is one of the few technologies with potential to develop efficient, environmentally benign, and compact processes. Novel fabrication and processing techniques, equipment, and operational methods are resulting in spectacular developments that go beyond "traditional" chemical engineering. These new developments promise improvements in process plants, and lead to the transformation of our concept of chemical plants into compact, safe, energy-efficient, and environmentally sustainable processes. Microsystems are now available in many devices for commercial applications including: micromixers and microreactors as alternative to batch production in pharmaceutical and fine chemical industry, lab-on-chip devices, microsensors, advanced rapid throughput chemical and catalyst screening tools (e.g. combi), distributed or portable power and chemical production, distributed heating and cooling, and even out of this world applications with NASA. A wide diversity of subjects are discussed in this book ranging from catalysis to fuel processing to combinatorial techniques to separations to novel reactors all of which are enabled by microtechnology principles. World renowned pioneers (Klavs Jensen, Volker Hessel, Jennifer Holmgren, and Galip Akay) provide accounts on both historical developments and the current state of the art as well as insights into future research and development in microreactor and process intensification. Research and developments are presented by industry, universities, U.S. National Laboratories, and other laboratories located in the United States and throughout the world. It is composed of peer-reviewed chapters from both contributing and invited authors. The review and original research topics include (1) introductory and general overviews, (2) microreactors- including catalysts for microreactors, fuel processors, milli-second contact time catalysis, gas to liquid technology, and biomass conversion; and (3) process intensification such as micro mixers, reactive membranes, and intensification of separation operations.

With the development of synthetic organic chemistry techniques in the early 19th century the world of synthetic FandF materials began and expanded, but it has not totally replaced natural FandF. A growing segment of the public prefers natural foods to foods containing artificial additives, and will pay a premium for natural foods. While modern synthetic methods permit the economical production of artificial FandF on a large scale, the natural FandF industry remains important. Why is thisso? How do the chemical, biological, and agricultural sciences support the natural FandF industry? What is the state of current natural FandF research? These are questions this volume attempts to address. Even considering only the value of FandF derived from essential oils, natural FandF constitute approximately a $2 billion annual business. The impact of FandF is best appreciated when you consider that a flavor or fragrance typically contributes only a very small part, both in cost and volume, to a finished product. Many analytical tools available do not have a detector that is as sensitive to taste or odor as a human (or many animals for that matter). The challenge for researchers is to sift FandF information from all the data obtained from the various analytical techniques. The intent of this book is to give the reader and appreciation for the many facets of the chemistry, analysis and production of natural flavors and fragrances. It is a field where each one of us who can smelland taste are active participants. New foods, plants, processes, packages and aromas are developed each day. Keeping researchers abreast of the many new facets of the natural FandF field have led to development of this chapter and the ACS symposium that served as the basis of this book.

The volume begins with an overview of POGIL and a discussion of the science education reform context in which it was developed. Next, cognitive models that serve as the basis for POGIL are presented, including Johnstone's Information Processing Model and a novel extension of it. Adoption, facilitation and implementation of POGIL are addressed next. Faculty who have made the transformation from a traditional approach to a POGIL student-centered approach discuss their motivations and implementation processes. Issues related to implementing POGIL in large classes are discussed and possible solutions are provided. Behaviors of a quality facilitator are presented and steps to create a facilitation plan are outlined. Succeeding chapters describe how POGIL has been successfully implemented in diverse academic settings, including high school and college classrooms, with both science and non-science majors. The challenges for implementation of POGIL are presented, classroom practice is described, and topic selection is addressed. Successful POGIL instruction can incorporate a variety of instructional techniques. Tablet PC's have been used in a POGIL classroom to allow extensive communication between students and instructor. In a POGIL laboratory section, students work in groups to carry out experiments rather than merely verifying previously taught principles. Instructors need to know if students are benefiting from POGIL practices. In the final chapters, assessment of student performance is discussed. The concept of a feedback loop, which can consist of self-analysis, student and peer assessments, and input from other instructors, and its importance in assessment is detailed. Data is provided on POGIL instruction in organic and general chemistry courses at several institutions. POGIL is shown to reduce attrition, improve student learning, and enhance process skills.

Boron compounds have been used extensively in organic synthesis for more than sixty years. Some of the best known reactions in synthesis, such as the Suzuki-Miyaura cross-coupling and the hydroboration reaction, involve boron compounds. Several natural products containing boron have been isolated in the last fifty years, including ionophoric macrodiolide antibiotics boromycin, borophycin, aplasmomycins A, B, and C, and tartrolons B, C, and E, as well as autoinducer-2. The study of compounds containing boronic acids for application in pharmaceuticals and materials science has grown tremendously over the last few decades. These include bortezomib, ixazomib, and tavaborole. Several more boron-based drugs are currently in clinical trials. Boron neutron capture therapy has the potential to provide a treatment for various cancers. In addition, materials bearing boronic acids are been studied as potential sensors for biological molecules, such as saccharides and glycoproteins that possess cis-1,2- or cis-1,3-diols.

Undergraduate research is a uniquely American invention. The ability to enter a laboratory and to embrace the unknown world, where a discovery is just around the corner, is a transformative experience. Undergraduate research, when done right, creates an authentic research project which changes the individual who is doing the research. Early introduction to authentic research captures student interest and encourages them to continue with their studies. The difficulty of undergraduate research is scale. To be truly authentic, and thus transformative, emerging scholars in the lab need to be guided by experts who clearly care for their junior collaborators. This apprenticeship model is time consuming, absolutely essential, and difficult to scale. To provide more authentic research experiences to students, dedicated teachers have developed the idea of course-based undergraduate research experiences (CUREs). This book offers a comprehensive overview of how authentic, early research is a strategy for student success. Dr. Desmond Murray and his co-authors demonstrate the importance of early introduction to authentic research for all students, including those that are most likely to be left out during the normal sink-or-swim research university science curriculum.
