From the late-1960's, perfluorosulfonic acid (PFSAs) ionomers have dominated the PEM fuel cell industry as the membrane material of choice. The "gold standard' amongst the many variations that exist today has been, and to a great extent still is, DuPont's Nafion (R) family of materials. However, there is significant concern in the industry that these materials will not meet the cost, performance, and durability requirementsnecessary to drive commercialization in key market segments - es- cially automotive. Indeed, Honda has already put fuel cell vehicles in the hands of real end users that have home-grown fuel cell stack technology incorporating hydrocarbon-based ionomers. "Polymer Membranes in Fuel Cells" takes an in-depth look at the new chem- tries and membrane technologies that have been developed over the years to address the concerns associated with the materials currently in use. Unlike the PFSAs, which were originally developed for the chlor-alkali industry, the more recent hydrocarbon and composite materials have been developed to meet the specific requirements of PEM Fuel Cells. Having said this, most of the work has been based on derivatives of known polymers, such as poly(ether-ether ketones), to ensure that the critical requirement of low cost is met. More aggressive operational requi- ments have also spurred the development on new materials; for example, the need for operation at higher temperature under low relative humidity has spawned the creation of a plethora of new polymers with potential application in PEM Fuel Cells.

Chemicals from Biomass: Integrating Bioprocesses into Chemical Production Complexes for Sustainable Development helps engineers optimize the development of new chemical and polymer plants that use renewable resources to replace the output of goods and services from existing plants. It also discusses the conversion of those existing plants into facilities that are based on renewable resources that may require nonrenewable resource supplements. Relying on extensive reviews of biomass as feedstock and the production of chemicals from biomass, this book identifies and illustrates the design of new chemical processes (bioprocesses) that use renewable feedstock (biomass) as raw materials. The authors show how these new bioprocesses can be integrated into the existing plant in a chemical production complex to obtain the best combination of energy-efficient and environmentally acceptable facilities. This presented methodology is an essential component of sustainable development, and these steps are essential to achieving a sustainable chemical industry. The authors evaluate potential bioprocesses based on a conceptual design of biomass-based chemical production, and they use Aspen HYSYS(r) and Aspen ICARUS(r) to perform simulations and economic evaluations of these processes. The book outlines detailed process designs created for seven bioprocesses that use biomass and carbon dioxide as feedstock to produce a range of chemicals and monomers. These include fermentation, transesterification, anaerobic digestion, gasification, and algae oil production. These process designs, and associated simulation codes, can be downloaded for modification, as needed. The methodology presented in this book can be used to evaluate energy efficiency, cost, sustainability, and environmental acceptability of plants and new products. Based on the results of that analysis, the methodology can be applied to other chemical complexes for new bioprocesses, reduced emissions, and energy savings.
The ultrasonic velocity profile (UVP) method, first developed in medical engineering, is now widely used in clinical settings. The fluid mechanical basis of UVP was established in investigations by the author and his colleagues with work demonstrating that UVP is a powerful new tool in experimental fluid mechanics. There are diverse examples, ranging from problems in fundamental fluid dynamics to applied problems in mechanical, chemical, nuclear, and environmental engineering. In all these problems, the methodological principle in fluid mechanics was converted from point measurements to spatio-temporal measurements along a line. This book is the first monograph on UVP that offers comprehensive information about the method, its principles, its practice, and applied examples, and which serves both current and new users. Current users can confirm that their application configurations are correct, which will help them to improve the configurations so as to make them more efficient and effective. New users will become familiar with the method, to design applications on a physically correct basis for performing measurements accurately. Additionally, the appendix provides necessary practical information, such as acoustic properties.

The environmental and health hazards created by industrial chemicals and consumer products must be minimized. For safer products to be designed, the relationships between structure and toxicity must be understood at the molecular level. Green chemistry combined with free radical research has the potential to offer innovative solutions to such problems. Some solutions are "greener then others," and many necessitate significant financial investment. New technology will only be adopted if real benefit can be shown and sometimes adaptation of existing methods is the best option. The efficiency of processes must be assessed, not only in terms of the final yield, but also cost, environmental impact and waste toxicity. This practical and concise guide showcases the sustainable methods offered by green free radical chemistry and summarizes the fundamental science involved. It discusses the pros and cons of free radical chemistry in aqueous systems for synthetic applications. All transformation steps are covered including initiation, propagation, and termination. Useful background knowledge is combined with examples, including industrial scale processes for pharmaceuticals and fine chemicals. The book helps chemists to choose appropriate methods for achieving maximum output using a modern, environmentally conscious approach. It shows that, armed with an elementary knowledge of kinetics, an understanding of the mechanistic and technical aspects, and some common sense, it is possible to harness free radicals for use in a broad range of applications. Streamlining Green Free Radical Chemistry is aimed at chemists, engineers, materials scientists, biochemists and biomedical experts, as well as undergraduate and postgraduate students. It encourages readers to question conventional methods and move towards the "Benign-by-Design" approach of the future. References to further reading are provided at the end of each chapter.

In Europe, the main oil-rich crops are sunflower, rapeseed and olive which are grown primarily for food. This book discusses how to convert this whole crop into energy (fuels, power and heat), food and bioproducts (chemicals and/or materials), whilst making optimal use of the by-products generated during farming/harvesting, primary processing (oil extraction and refining) and secondary processing (transesterification). The resulting processes are more economically competitive and the business margin for oil and biodiesel manufacturers is improved. Previously, oil crops have been the main point of focus but many of the technologies used are applicable to a wide variety of raw materials. For example, cellulose from rapeseed straw can be converted to levulinic acid but the same technology could be applied to cellulose from wheat straw or wood. Significant effort is now being devoted to '2nd generation' raw materials such as ligno-cellulose which avoid direct competition with food sources. This volume integrates these developments with existing plant oil supply chains and combines biochemical and thermochemical processes to form integrated biorefinery schemes. Two unique features of the book are the information on LCA of biorefinery schemes and the surveys showing where traditional industries could be affected by new biorefinery developments. Energy and cost calculations for the key biorefinery processes and are also included revealing that some are surprisingly profitable and could offer significant global benefits. Other topics covered include: novel farming and harvesting methods, efficient extraction of plant oils, producing biodiesel without glycerol, extraction of high value chemicals from agricultural by-products, anaerobic digestion potential of agricultural by-products, use of proteins to yield amino acids, economics and life cycle analysis, stakeholder surveys, and policy scenarios. The book is of interest to academics working in relevant areas of chemistry, biology, materials, engineering, economics and policy studies. Those working in the EU farming industry will also find it relevant to their business.
The discovery of the spatial structure of the double-stranded
DNA molecule is one of the greatest achievements of science. It
would not be an exaggeration to say that the DNA double helix is a
distinguished symbol of modern biology.
This book focuses on pulverized coal particle devolatilization, ignition, alkali metal release behavior, and burnout temperature using several novel optic diagnostic methods on a Hencken multi-flat flame burner. Firstly, it presents a novel multi-filter technique to detect the CH* signal during coal ignition, which can be used to characterize the volatile release and reaction process. It then offers observations on the prevalent transition from heterogeneous ignition to hetero-homogeneous ignition due to ambient temperature based on visible light signal diagnostics. By utilizing the gap between the excitation energies of the gas and particle phases, a new low-intensity laser-induced breakdown spectroscopy (PS-LIBS) is developed to identify the presence of sodium in the particle or gas phase along the combustion process. For the first time, the in-situ verification of the gas phase Na release accompanying coal devolatilization is fulfilled when the ambient temperature is high enough. In fact, particle temperature plays a vital role in the coal burnout process and ash particle formation. The last part of the book uses RGB color pyrometry and the CBK model to study the char particle temperature on a Hencken burner. It offers readers valuable information on the technique of coal ignition and combustion diagnostics as well as coal combustion characteristics.

Chemistry of Modern Papermaking presents a chemist's perspective on the papermaking process. With roughly 3% of the mass of a paper product invested in water-soluble chemicals, paper makers can adjust the speed and efficiency of the process, minimize and reuse surplus materials, and differentiate a paper product as required by specific customers. With research and development scattered across academic journals or the proprietary information of a variety of companies, the modern paper maker requires a one-stop resource for the general picture of the paper chemicals organic chemistry. The remarkable effectiveness of chemicals at very low concentrations is a fascinating topic in paper chemistry. Chemistry of Modern Papermaking is an extensive collection of data combining the organic chemistry of paper with its potential applications. Within each chapter, paper chemicals are organized based on their chemical structure. After an introduction and brief history, the book explores the papermaking process, retention aids, temporary wet strength resins, wet strength resins, dry strength resins, internal sizing agents, creping adhesives and softeners, and chemicals for paper surface treatment. Uniquely, patents and scientific articles are included in almost equal number among the 3400 references. Chemistry of Modern Papermaking focuses on the chemistry behind each application, on what has been done, and on what can be done. Never before has a book analytically arranged and lucidly explained such an expansive collection of details from both the patent and scientific literature. This synthesis is achieved not only through diligent work, but also through years of industrial experience. |
