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.
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.
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 where precise structural determination is required and
where the nature of interactions and reactions in solution is being
studied. Annual Reports on NMR has established itself as a premier
means for the specialist and nonspecialist alike to become familiar
with new techniques and applications of NMR spectroscopy.
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.
The Nobel Prize is the only scientific prize that has achieved worldwide recognition among the general public. Each year, announcement of the prizes is covered by the national news media, and countries and universities brag about how many Nobel Prize winners they have. As of 2015, 172 individuals have received the Nobel Prize in chemistry. This book explores the reasons why the Nobel Prize has not been awarded to various deserving chemists over the years, and points specifically to eleven deceased chemists in particular who did not receive the Nobel Prize in Chemistry.
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.
Advances in Physical Organic Chemistry provides the chemical community with authoritative and critical assessments of the many aspects of physical organic chemistry. The field is a rapidly developing one, with results and methodologies finding applications from biology to solid state physics. This text is ideal for those interested in the relationship between the structure and function of organic compounds, including physical and theoretical chemists as well as organic and bioorganic chemists.
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.
This book is concerned with two major industrial minerals: Lithium
and Calcium Chloride. The geology of their deposits is first
reviewed, along with discussions of most of the major deposits and
theories of their origin. The commercial mining and processing
plants are next described, followed by a review of the rather
extensive literature on other proposed processing methods. The more
important uses for lithium and calcium chloride are next covered,
along with their environmental considerations. This is followed by
a brief review of the production statistics for each industry, and
some of their compounds' phase data and physical properties.
This volume is an attempt to educate, to provide a source of information, knowledge, and wisdom to the person who has spent so much time and energy on his or her schooling. The Council for Chemical Research (CCR) and the American Chemical Society (ACS) have both spent considerable effort over the past decades focusing on how to ensure that graduate education in the chemical sciences remains at the absolute highest caliber, and produces the best possible professionals. In spite of notable efforts from both organizations to prepare graduate students for the professional world, neither has specifically asked what a person needs to be successful once they have both the Ph.D. and the first job in hand. Put succinctly, there is much more to being successful in a career in chemistry than just the hard-earned Ph.D. degree. What You Need for the First Job, Besides the Ph.D. in Chemistry is based on a symposium of the same name held at the 246th National Meeting of the American Chemical Society, which took place in Indianapolis, Indiana in September, 2013. This book is the result of seeds that were planted during numerous informal conversations at the annual meetings of the CCR, as well as during such discussions at national and regional meetings of the ACS, and at the ACS employment clearing houses. The authors felt that the same intense focus a person needs to earn a Ph.D. might actually work against the attention to other details needed in order to be successful once he or she has obtained a position. Leaders want to ensure that new hires are working effectively toward tenure, are quickly becoming productive members of their corporate team, or are well integrated into their government laboratory research group. While it is easy to lump factors other than technical competence in one's job under the term "soft skills," this is an oversimplification. This book represents an attempt to have voices from all three pillars of the chemical enterprise - academia, industry, and government laboratories - heard in terms of relating what is important for their newly hired Ph.D.-holders. What You Need for the First Job, Besides the Ph.D. in Chemistry will be a valuable resource for first-time job seekers, as well as those with aspirations of a future career in the chemical sciences.
This third volume of NMR Spectroscopy in the Undergraduate Curriculum continues the work we started with the first and second volumes in providing effective approaches for using nuclear magnetic resonance spectrometers as powerful tools for investigating a wide variety of phenomena at the undergraduate level. This volume focuses on upper-level courses and NMR spectroscopy across the curriculum. The applications and strategies in this volume will be helpful to those who are looking to transform their curriculum by integrating more NMR spectroscopy, to those who might not have considered NMR spectroscopy as a tool for solving certain types of problems, or for those seeking funding for a new or replacement NMR spectrometer.
Aiming to provide the reader with a general overview of the mathematical and numerical techniques used for the simulation of matter at the microscopic scale, this book lays the emphasis on the numerics, but modelling aspects are also addressed. The contributors come from different scientific communities: physics, theoretical chemistry, mathematical analysis, stochastic analysis, numerical analysis, and the text should be suitable for graduate students in mathematics, sciences and engineering and technology.
This book will explore our forests as the most readily available and renewable source of carbon as well as the building block of chemicals, plastics, and pharmaceuticals as the next 100 years gradually push consumers toward alternate sources of chemicals. Meeting these needs from trees requires that new chemistry be developed so that plant materials is converted to commodity chemicals. This focused discussion on ongoing global efforts at creativity using forest and biomass based renewable materials will include six different mechanisms for bringing about change on this very innovative topic.
This, the most recent contribution to the Tetrahedron Organic Chemistry series, provides an integrated evaluation of the diversity of natural products in relation to biodiversity. The ongoing exploitation of biological resources, while maintaining an effective equilibrium on Earth, depends much on the conservation of biodiversity. To this end, parts one and two focus on biodiversity from all viewpoints, while explaining the link with natural products. The third section concentrates on the molecular-shape level, as a link to ecosystem and biodiversity, while the fourth section tackles actual functionalization, as a link to biodiversity at species level. Part five addresses the diversification of these resources from biotechnology and chemical technology, while the final part is concerned with maintaining natural product diversity on Earth.
This ACS Symposium Series is the product of a symposium held at the 241st National Meeting of the American Chemical Society in Anaheim, CA on March 27-31, 2011. It includes chapters on new biobased building blocks such as the furandicarboxylic acid, polyesters and polyamides from adipic, succinic and sebacic acids with aliphatic diols such as 1,3-propylene glycol, 1,4-butanediol, 1,12-dodecylenediol and isosorbide. The conversion of hydroxymethylfurfural, the dehydration product of hexose sugars, to succinic acid and 1,4-butanediol to produce poly(butylene succinate) is described in one chapter. Also the synthesis of new polymers from plant-derived olefinic monomers such as tulipalin A and studies of composites from cotton by-products are featured in other chapters. There is a strong emphasis on biocatalytic synthesis and polymerization within the book. Chapter topics include the synthesis of ?-hydroxyfatty acids and polymers therefrom, an interesting discussion on the structural differences of the products of the biocatalytic and chemical catalytic synthesis of polyesters from oleic diacid and glycerol and the ability to produce polylactic acid (PLA) and PLA-PHA copolyesters within a "microbial cell factory". Other areas of interest explored in other chapters include recent developments of biobased polymer fibers and oleate-based pressure sensitive adhesives and composites. One chapter describes a large increase in cold-drawn fiber tensile strength by the blending of a small amount of ultrahigh molecular weight (MW) poly(3-hydroxybutyrate) with a much lower MW 3-hydroxybutyrate polymer. The addition of a rubber and inorganic fillers to normally brittle PLA was found to dramatically improve its ductility. Finally, there are several chapters on seed oil-based polyurethanes, one on fibers from soy proteins and composites from starch.
People are immersed in electromagnetic fields from such sources as
power lines, domestic appliances, mobile phones, and even
electrical storms. All living beings sense electric fields, but the
physical origins of the phenomenon are still unclear.
Magnetobiology considers the effects of electromagnetic fields on
living organisms. It provides a comprehensive review of relevant
experimental data and theoretical concepts, and discusses all major
modern hypotheses on the physical nature of magnetobiological
effects. It also highlights some problems that have yet to be
solved and points out new avenues for research.
Both technically and economically, additives form a large and
increasingly significant part of the polymer industry, both
plastics and elastomers. Since the first edition of this book was
published, there have been wide-ranging developments, covering
chemistry and formulation of new and more efficient additive
systems and the safer use of additives, both by processors in the
factory and, in the wider field, as they affect the general public.
This new edition follows the successful formula of its
predecessor, it provides a comprehensive view of all types of
additives, concentrating mainly on their technical aspects
(chemistry/formulation, structure, function, main applications)
with notes on the commercial background of each. The field has been
expanded to include any substance that is added to a polymer to
improve its use, so including reinforcing materials (such as glass
fibre), carbon black and titanium dioxide. This is a book which has been planned for ease of use and the information is presented in a way which is appropriate to the users' needs.
Since the first publication of this definitive work nearly 40 years ago, this fourth edition has been completely rewritten. Crystallization is used at some stage in nearly all process
industries as a method of production, purification or recovery of
solid materials.
This volume comprehensively examines the synthesis, spectroscopic properties, reactivity and catalytic applications of all phosphorus-carbon heterocycles. The most significant phosphorus heterocycles incorporating other heteroatoms, such as heterophospholes and heterophosphinines, are also covered. The introductory chapter describes the rise of this field that has developed, over the years, into the fourth major branch of heterocyclic chemistry. Written by several founders of the field, this book should prove a useful reference work within the domain for years to come and provide the basis for courses on heterocyclic chemistry and homogenous catalysis. All those interested in phosphorus heterocycles for applications in co-ordination chemistry, homogenous catalysis, molecular materials and biochemistry, should find this volume useful.

This third edition of Peter Bernath's successful Spectra of Atoms and Molecules is designed to provide advanced undergraduates and graduate students a working knowledge of the vast field of spectroscopy. Also of interest to chemists, physicists, astronomers, atmospheric scientists, and engineers, this volume emphasizes the fundamental principles of spectroscopy with the primary goal of teaching the interpretation of spectra. Features include a presentation of group theory needed to understand spectroscopy, detailed worked examples and a large number of excellent problems at the end of each chapter. Prof. Bernath provides a large number of diagrams and spectra which have been specifically recorded for this book. Molecular symmetry, matrix representation of groups, quantum mechanics, and group theory are among the topics covered; atomic, rotational, vibrational, electronic and Raman spectra are analyzed. Bernath's clear treatment of the confusing topic of line strengths as needed for quantitative applications is featured. This much-needed new edition has been updated to include the 2010 CODATA revision of physical constants, and a large number of corrections and clarifications. Responding to student requests, the main new feature is the addition of detailed worked examples in each chapter. Spectra of Atoms and Molecules, 3e will help demystify spectroscopy by showing readers the necessary steps in a derivation, as well as the final result.
This volume brings together contributions by leading researchers
covering a wide scope so characteristic of fluorine chemistry. It
is a monograph of historical character comprising personalized
accounts of progress and events in areas of particular interest.
This volume of "Progress in Heterocyclic Chemistry" (PHC) is the twelfth annual review of the literature, covering the work published on most of the important heterocyclic ring systems during 1999, with inclusions of earlier material as appropriate. As in PHC-11, there are also three specialized reviews in this year's volume. In the inaugural chapter, Michael Groziak revitalizes the field of boron heterocycles, a relatively obscure class of heterocycles, but with a promising future. Heterocyclic phosphorus ylides are similarly a little known but useful class of compounds and Alan Aitken and Tracy Massil have provided a comprehensive review of them in Chapter 2. In Chapter 3 Jack Li discusses the remarkably versatile palladium chemistry in pyridine alkaloid synthesis. The subsequent chapters deal with recent advances in the field
of heterocyclic chemistry arranged by increasing ring size and with
emphasis on synthesis and reactions. |
