Polymeric materials have been and continue to be a focus of
research in the development of materials for energy conversion,
storage and delivery applications (fuel cells, batteries,
photovoltaics, capacitors, etc.). Significant growth in this field
started in the early 1990s and has continued to grow quite
substantially since that time. Polymeric materials now have a
prominent place in energy research.
Developing innovative efficient and sensitive spectroscopic and optical techniques for studying biomedically relevant molecules, structures and processes in vitro and in vivo is a field of rapidly growing interest. This symposium book covers novel and exciting approaches in biomedical spectroscopy. Several chapters deal with infrared and Raman spectroscopy. These complimentary vibrational spectroscopic techniques are capable of monitoring molecular structures as well as structural changes. Such studies are of interest for understanding diseases at a molecular level as well as for developing techniques for efficient early diagnosis based on molecular structural information. The chapters demonstrate also applications vibrational spectroscopy in proteomics and the characterization of micro organisms. The second section of the book introduces surface enhanced Raman scattering (SERS), demonstrates the application of the effect in the biomedical field and develops the concept of multifunctional nanosensors. The measurement of intrinsic optical signals from biological objects such as nerve tissue are discussed in the next section of the book. Chapters deal also with Coherent anti-Stokes Raman scattering (CARS) and fluorescence fluctuation spectroscopy. Other chapters illustrate how photons of very different energies, in the Terahertz and in the ultra violet range, can be used to retrieve molecular structural information from native biomolecules. The electrical properties of protein molecules adsorbed onto a gold substrate are studied by using a scanning Kelvin nanoprobe in a microarray format. The final chapters in the book demonstrate the powerful combination of different spectroscopic techniques for the characterization of biomolecules as well as native and engineered biomaterials. These chapters combine information from Raman and Inelastic Neutron Scattering, optical absorbance and energy dispersive X-ray analysis, positron annihilation lifetime spectroscopy (PALS), 1H NMR, and 129Xe NMR X-ray diffraction and fluorescence resonance energy transfer.
Professors and research advisors have always endeavored to make the opportunity to gain new knowledge available to their students. However, new knowledge takes different forms. From a student perspective, it comes from reading textbooks and primary literature or attending classes and seminars. Professors share in these activities with their students, but they know that physically taking part in the acquisition of new knowledge through active research is where the true excitement begins. For many, if not all, faculty members research is the source of passion for chemistry, and sharing it with a rising generation of chemists often comprises a substantial part of the decision to pursue a career in the field of undergraduate education. These chapters and additional ones provide starting points for developing such a culture at the department level. In several cases the starting point is redesigning introductory or research methods courses to place a stronger emphasis on authentic research and its associated skills. In other cases the establishment of a thriving research group by one faculty member is the catalyst for initiating the departmental transformation. There are also several examples of how to set up an undergraduate research group in departments that place a heavy emphasis on research, and those that place less emphasis on research. Many of these offer roadmaps for developing interdisciplinary research groups or translating resource-intensive graduate-level research to an environment that is resource-restrictive. In still other cases the research has an experiential learning component. For many of the above examples the departmental/institutional role is not always obvious and may not be influential or important. This is a reminder that undergraduate research need not be "institutional" to be successful.

Chiral molecules are ubiquitous in nature. Thus, it is not surprising to come across this phenomenon in the world of flavor substances. This book provides an overview on the analytical procedures currently applied to analyze chiral flavor substances at trace levels. It demonstrates several examples for the application of these techniques to determine naturally occurring enantiomeric compositions of chiral key flavor compounds in various natural systems. In addition to the analytical aspects, the contributions focus on the sensory properties of enantiomers and enlarge our knowledge on the correlation between configurations and odor properties and intensities of chiral flavor compounds. The practical importance of the topic is reflected by a discussion of merits and limitations of chiral analysis for the authenticity control of food flavorings. In addition, examples for the use of enzymes and microorganisms to obtain enantiopure flavor substances and thus to meet legal requirements for "natural" labeling are presented. Finally, the book covers aspects recently getting more and more in the focus of flavor science: What are the physiological mechanisms underlying the perception of sensory properties and does chirality matter in that respect?
The field of quantum chemistry has grown so immensely that the importance of some of the earliest work and the earliest pioneers of quantum chemistry is unfamiliar to many of today's youngest scientists in the field. Thus, this book is an attempt to preserve some of the very valuable, early history of quantum chemistry, providing the reader with not only a perspective of the science, but a perspective of the early pioneers themselves, some of whom were quite interesting characters. The symposium on which this book is based came about because one of the co-editors (ETS) came to a conviction that the contributions such as those by George Wheland to quantum chemistry and Otto Schmidt to free electron theory should be better appreciated and known. He organized a symposium in which quantum chemistry pioneers, both those celebrated by everyone and those seemingly overlooked by posterity, would be recognized. While this volume is certainly not a history of quantum chemistry, it does cover many highlights over a period of about sixty years. This volume consists of chapters based upon ten of the presentations at the symposium "Pioneers of Quantum Chemistry" held March 28, 2011, at the 241st ACS National Meeting in Anaheim, CA.
This book offers a broad discussion of the concepts required to
understand the thermodynamic stability of molecules and bonds and a
description of the most important condensed-phase techniques that
have been used to obtain that information. Above all, this book
attempts to provide useful guidelines on how to choose the "best"
data and how to use it to understand chemistry. Although the book
assumes some basic knowledge on physical-chemistry, it has been
written in a "textbook" style and most topics are addressed in a
way that is accessible to advanced undergraduate students. Many
examples are given throughout the text, involving a variety of
molecules.
Starting from a clear, concise introduction, the powerful finite element and boundary element methods of engineering are developed for application to quantum mechanics. The reader is led through illustrative examples displaying the strengths of these methods using applications to fundamental quantum mechanical problems and to the design/simulation of quantum nanoscale devices.
Chemistry is intimately involved in the development of the oldest known civilizations, resulting in a range of chemical technologies that not only continue to be part of modern civilized societies, but are so commonplace that it would be hard to imagine life without them. Such chemical technology has a very long and rich history, in some cases dating back to as early as 20,000 BCE. Chemistry Technology in Antiquity aims to present the discovery, development, and early history of a range of such chemical technologies, with the added goal of including a number of smaller subjects often ignored in the presentation of early chemical technology. While the book does not aim to be a comprehensive coverage of the full range of chemical technologies practiced during antiquity, it provides a feel and appreciation for both the deep history involved with these topics, as well as the complexity of the chemical processes that were being utilized at such a very early time period.

Increased energy prices and the growing attention on global warming are motivating the creation of economically viable alternatives to fossil fuels. Nanotechnologies have been recognized as one effective approach to solve energy problems. Therefore, to promote the improvement of research and to foster professional collaboration among researchers in energy-related nanotechnologies, we organized a symposium on "Nanotechnology for a Sustainable Energy Economy" as a part of the 243rd American Chemical Society National Meeting, which took place March 25-29, 2012 in San Diego, California, USA. Forty-four contributors from 12 countries presented their research works from industrial, university, and national laboratories in nanotechnology areas related to energy and fuel technologies. This ACS Symposium Series book was developed from this symposium. This book presents a very useful and readable collection of reviews and research papers in nanotechnologies for energy conversion, storage, and utilization, offering new results which are sure to be of interest to researchers, students, and engineers in the field of nanotechnologies and energy. The book focuses on the following topics: Li batteries (Chapters 1-4), supercapacitors (Chapter 5), dye-sensitized solar cells (Chapter 6), photocatalysis (Chapters 7-9), fuel cells (Chapter 10), electrocatalysis (Chapter 11), and electron beam lithography (Chapter 12). All 12 chapters were recruited from oral presentations at the symposium.
