E. Thomas Strom, Vera V. Mainz
R5,475 Discovery Miles 54 750 Ships in 10 - 15 working days

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.

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.

African American Women Chemists (Hardcover): Jeannette Brown African American Women Chemists (Hardcover)
Jeannette Brown
R1,380 Discovery Miles 13 800 Ships in 10 - 15 working days

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.
The book contains sketches of the lives of African America women chemists from the earliest pioneers up until the late 1960's when the Civil Rights Acts were passed and greater career opportunities began to emerge. In each sketch, Brown will explore women's motivation to study the field and detail their often quite significant accomplishments. Chapters focus on chemists in academia, industry, and government, as well as chemical engineers, whose career path is very different from that of the tradition chemist. The book concludes with a chapter on the future of African American women chemists, which will be of interest to all women interested in science.

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.
The second section focuses on molecular biological approaches to control mycotoxin exposure. Topics covered include genomic approaches, detoxification, structure-activity studies of biosynthetic precursors, and mycotoxin biosynthesis. The success of these strategies is supported by the reduction of mycotoxin occurrence and incidence in foods. Accurate estimates of mycotoxin concentration in foods are important for food safety and wholesomeness.
The final section covers analytical approaches, including sampling plans for foods and dietary supplements, extraction efficiency of mycotoxins from naturally contaminated grains, traditional detection methods such as chromatography/mass spectrometry, and emerging techniques such as the use of molecularly imprinted polymers for purification and isolation and cyclodextrins for fluorescent enhancement of several mycotoxins.

The Properties of Water and their Role in Colloidal and Biological Systems, Volume 16 (Hardcover): Carel Jan Van Oss The Properties of Water and their Role in Colloidal and Biological Systems, Volume 16 (Hardcover)
Carel Jan Van Oss
R4,550 Discovery Miles 45 500 Ships in 10 - 15 working days

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.
The book also treats the surface properties of apolar and polar molecules, polymers, particles and cells, as well as their mutual interaction energies, when immersed in water, under the influence of the three prevailing non-covalent forces, i.e., Lewis acid-base (AB), Lifshitz-van der Waals (LW) and electrical double layer (EL) interactions. The polar AB interactions, be they attractive or repulsive, typically represent up to 90% of the total interaction energies occurring in water. Thus the addition of AB energies to the LW + EL energies of the classical DLVO theory of energy vs. distance analysis makes this powerful tool (the Extended DLVO theory) applicable to the quantitative study of the stability of particle suspensions in water. The influence of AB forces on the interfacial tension between water and other condensed-phase materials is stressed and serves, inter alia, to explain, measure and calculate the driving force of the hydrophobic attraction between such materials (the "hydrophobic effect"), when immersed in water. Thesephenomena, which are typical for liquid water, influence all polar interactions that take place in it. All of these are treated from the viewpoint of the properties of liquid water itself, including the properties of advancing freezing fronts and the surface properties of ice at 0o C.
- Explains and allows the quantitative measurement of hydrophobic attraction and hydrophilic repulsion in water
- Measures the degree of cluster formation of water molecules
- Discusses the influence of temperature on the cluster size of water molecules
- Treats the multitudinous effects of the hyper-hydrophobicity of the water-air interface

Aggregation-Induced Emission: Materials and Applications Volume 2 (Hardcover): Michiya Fujiki, bin Liu, Ben Zhong Tang Aggregation-Induced Emission: Materials and Applications Volume 2 (Hardcover)
Michiya Fujiki, bin Liu, Ben Zhong Tang
R4,839 Discovery Miles 48 390 Ships in 10 - 15 working days

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.

Chiral Pesticides - Stereoselectivity and Its Consequences (Hardcover, New): A. Wayne Garrison, Jay Gan, Weiping Liu Chiral Pesticides - Stereoselectivity and Its Consequences (Hardcover, New)
A. Wayne Garrison, Jay Gan, Weiping Liu
R2,730 Discovery Miles 27 300 Ships in 10 - 15 working days

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.
This book is a result of manuscript contributions by some of the oral and poster presenters to the third symposium in 2010. In addition to symposium participants, invitations were extended to the environmental chiral chemistry community in general, including most of the speakers in the 2005 and 2007 symposia, in an attempt to attain good coverage of this rather broad topic. Thus, this ACS Symposium book will generate many new ideas from interested readers and inform them of useful techniques for experimental exploration of the somewhat exotic, but important, area of chiral chemistry of pesticides.

Volume 8: Hyphenated Methods

Starting with gas chromatography-mass spectrometry (GC-MS) and continuing through GCxGC-MS, LC-MSn, and LC-NMR-MS, hyphenated methods have revolutionized chemical analysis. This volume covers that revolution in two parts. The first (Chapters 1-4) describes principles, instrumentation, and technology, and the second (Chapters 5-10) organizes major application areas in GC-MS and LC-MS.

After a general introduction (Chapter 1), attention is paid to principles and instrumentation of GC-MS (Chapter 2) and LC-MS (Chapter 3). Other hyphenated methods, including online combinations of capillary electromigration methods and supercritical fluid chromatography with mass spectrometry, are in Chapter 4.

Applications are then covered in the remaining chapters. The application-oriented chapters are focused on the role of mainly LC-MS in the pharmaceutical field (Chapter 5) and biochemical and biotechnological applications (Chapter 10), and the application of both GC-MS and LC-MS in relation to environmental analysis (Chapter 6), food safety and food analysis (Chapter 7), characterization of natural products (Chapter 8), and clinical, toxicological, and forensic analysis (Chapter 9).

Volume 6: Ionization Methods

Volume 6 captures the story of molecular ionization and its phenomenal evolution that makes mass spectrometry the powerful method it is today. Chapters 1 and 2 cover fundamentals and various issues that are common to all ionization (e.g., accurate mass, isotope clusters, and derivatization).

Chapters 3-9 acknowledge that some ionization methods are appropriate for gas-phase molecules and others for molecules that are in the solid or liquid states. Chapters 3-6 cover gas-phase molecules, dividing the subject into: (1) ionization of gas-phase molecules by particles (e.g., EI), (2) ionization by photons, (3) ionization by ion-molecule and molecule-molecule reactions (e.g., APCI and DART), and ionization in Strong electric fields (i.e., Electrohydrodynamic and Field Ionization/Desorption).

"Ionization in a Strong Electric Field" illustrates the transition to ionization of molecules in the solid or liquid states, covered in Chapters 7-9: (1) spray methods for ionization (e.g., electrospray), (2) desorption ionization by particle bombardment (e.g., FAB), and (3) desorption by photons (e.g., MALDI). Electrospray and MALDI also lead to applications in biophysical chemistry, the theme of Chapter 10.

Chapter 11 reconsiders ionization from the view of choosing an ionization method. The range of subjects is from ionization of organic and biomolecules to the study of microorganisms.
* reviews range of ionization methods used in mass spectrometry today
* includes tutorials describing the principles and instrumentation applied to each method
* considers appropriate methods of ionization for analysis of various substances

100+ Years of Plastics - Leo Baekeland and Beyond (Hardcover): E. Thomas Strom, Seth Rasmussen 100+ Years of Plastics - Leo Baekeland and Beyond (Hardcover)
E. Thomas Strom, Seth Rasmussen
R5,463 Discovery Miles 54 630 Ships in 10 - 15 working days

This volume consists of written chapters taken from the presentations at the symposium "100+ Years of Plastics: Leo Baekeland and Beyond," held March 22, 2010, at the 239th ACS National Meeting in San Francisco. The symposium celebrates the 100th anniversary of the formation of General Bakelite Corp., which was preceded by Leo Baekland's synthesis of Bakelite in 1907 and the unveiling of the Bakelite process in 1909. It is quite reasonable to use the synthesis of Bakelite as the starting point of the Age of Plastics. Indeed, Time magazine in its June 14, 1999, issue on the 100 most influential people of the 20th century chose Leo Baekeland and his Bakelite synthesis as the sole representative of chemistry.
Leo Baekeland and Bakelite are the topics of the first four chapters of this volume. The first two chapters come from the perspective of Baekeland family members. Carl Kaufmann is related to the Baekeland family through marriage and is the author of the only full-length biography of Baekeland, published as a master's thesis from the University of Delaware. As a family member Kaufmann had access to all of Baekeland's papers. This first chapter (Leo H. Baekeland) is not only a biographical sketch, but an exploration of Baekeland's effect on the chemical industry. Hugh Karraker is Baekeland's great-grandson, and his chapter (A Portrait of Leo H. Baekeland) provides a family picture of the great inventor. Gary Patterson's chapter (Materia Polymerica: Bakelite) goes into the history of Bakelite chemistry, while Burkhard Wagner's contribution (Leo Baekeland's Legacy-100 Years of Plastics) covers the history of Bakelite manufacture through time and space, finishing with a description of another Baekeland legacy, the Baekeland Award given through the North Jersey Section of the ACS.
In later chapters, Les Sperling (History of Interpenetrating Polymer Networks Starting with Bakelite-Based Compositions) covers the improvements in interpenetrating networks. James Economy and Z. Parkar (Historical Perspectives on Phenolic Resins and High-Temperature Aromatic Polyesters of p-Hydroxybenzoic Acid and Their Copolyesters) follow the paths of resoles, novolaks, and related chemicals.

Controlling Maillard Pathways To Generate Flavors (Hardcover): Donald Mottram, Andrew Taylor Controlling Maillard Pathways To Generate Flavors (Hardcover)
Donald Mottram, Andrew Taylor
R5,459 Discovery Miles 54 590 Ships in 10 - 15 working days

The role of the Maillard reaction in forming flavors from amino acid and sugar precursors has been studied for many years. To establish the basic chemistry of the reaction, researchers have used model systems, often solutions of a single amino acid with a single sugar. Despite the apparent simplicity of the system, heating such a solution can generate tens if not hundreds of compounds, which requires careful and time-consuming analysis to identify and quantify each component.
Data from the model systems has allowed researchers to study the pathways that lead to flavor formation, and various schemes have been proposed to identify the main "routes" that lead to flavor compounds. Such schemes have led to one of the main control principles, namely an understanding of the role of amino acids in forming some characteristic aromas, e.g., bread flavor from proline, as well as an appreciation of the role of C5 and C6 sugars in controlling the rate of reaction.
Recently, the formation of taste compounds through the Maillard reaction has been investigated and new potent compounds have been discovered that can contribute to the overall flavor formed during the Maillard reaction. These findings also offer the potential for control and manipulation of the Maillard reaction to form specific types of flavor. Although the nature of the end-products of the Maillard reaction in both food and model systems are well documented, applying these principles to control flavor formation in real foods has proved difficult.
This book describes recent research and developments related to the control of the Maillard reaction to give optimum flavor quality. These include kinetic modeling of the reaction, the effect of physical parameters (temperature, time, moisture content, pH), and the effect of chemical parameters (amino acid and sugar composition, the presence of other components). The topics covered relate to real food systems and reaction product flavorings, as well as model systems. Contributors from academia and industry have come together to provide an up to date overview of progress in this important area of flavor research.

Lipid Oxidation (Hardcover, 2nd edition): E N Frankel Lipid Oxidation (Hardcover, 2nd edition)
E N Frankel
R4,499 Discovery Miles 44 990 Ships in 10 - 15 working days

In this second edition, Edwin Frankel has updated and extended his now well-known book Lipid oxidation which has come to be regarded as the standard work on the subject since the publication of the first edition seven years previously. His main objective is to develop the background necessary for a better understanding of what factors should be considered, and what methods and lipid systems should be employed, to achieve suitable evaluation and control of lipid oxidation in complex foods and biological systems.
The oxidation of unsaturated fatty acids is one of the most fundamental reactions in lipid chemistry. When unsaturated lipids are exposed to air, the complex, volatile oxidation compounds that are formed cause rancidity. This decreases the quality of foods that contain natural lipid components as well as foods in which oils are used as ingredients. Furthermore, products of lipid oxidation have been implicated in many vital biological reactions, and evidence has accumulated to show that free radicals and reactive oxygen species participate in tissue injuries and in degenerative disease.
Although there have been many significant advances in this challenging field, many important problems remain unsolved. This second edition of Lipid oxidation follows the example of the first edition in offering a summary of the many unsolved problems that need further research. The need to understand lipid oxidation is greater than ever with the increased interest in long-chain polyunsaturated fatty acids, the reformulation of oils to avoid hydrogenation and trans fatty acids, and the enormous attention given to natural phenolic antioxidants, including flavonoids and other phytochemicals.
