Available in PDF, EPUB and Kindle. Book excerpt: The goal of reduced emissions and increased efficiency in transportation has required investigation into advanced engine designs. Some of these advanced engines use charge reactivity to closely control the engine ignition and combustion process and thus the overall engine operation. Reactivity controlled operation requires models of the chemical kinetics at the low end of operating temperatures. The current models are lacking detail in the low and intermediate temperature region where hydroxyl (OH), hydroperoxy (HO2), and alkylperoxy (RO2) radicals play an important role in the oxidation chemistry. Measurement of these radicals is made difficult in combustion systems because of the strongly absorbing stable products of combustion, such as CO2 and H2O, which obscure the absorption features of HO2 and RO2. Therefore, there is a need for sensitive and selective diagnostics which can quantitatively measure these weakly absorbing small peroxy radicals in combustion systems. This work advances the development and application of a sensitive and selective laser diagnostic technique called Cavity Enhanced Magneto-Optic Rotation (CEMOR) for quantitative measurement of paramagnetic species, specifically HO2 radicals. CEMOR combines the sensitivity of cavity ringdown spectroscopy (CRDS) and the selectivity of magneto-optic rotation (MOR) spectroscopy. This work presents a novel design of CEMOR with a continuous wave laser source for measurement of HO2. The narrower bandwidth of continuous wave lasers offers increased spectroscopic resolution over the pulsed Nd:YAG/OPO laser used for previous CEMOR development. Continuous wave cavity ringdown spectroscopy (cw-CRDS) is integrated with MOR in order to make high resolution scans of HO2 in a flash photolysis cell. Modeling results of the magnetic field strength in studies of MOR and CEMOR with a slot burner using permanent magnets, and of CEMOR in a flash photolysis cell using a solenoid are presented. Magnetic field strength effect is shown to have a linear relationship with MOR signal and a mechanism for measurement of its effect on CEMOR signal is described. The objective of this dissertation is to demonstrate that CEMOR can be used to make measurements of HO2 by increasing its resolution through the incorporation of a continuous wave distributed feedback (DFB) diode laser. The intellectual merit of this work is found in the design of a novel laser spectroscopy technique which is capable of sensitive and selective detection of paramagnetic species. This initial work did not demonstrate successful application of continuous wave CEMOR to measurement of HO2, yet it provides a path forward for this goal in a flash photolysis cell and cool flame burner. The present work also provides a method which can easily be adapted to measurement of alkyl peroxy (RO2) radicals.

Download or read book Fluorescent Nanodiamonds written by Huan-Cheng Chang and published by John Wiley & Sons. This book was released on 2018-11-12 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most comprehensive reference on fluorescent nanodiamond physical and chemical properties and contemporary applications Fluorescent nanodiamonds (FNDs) have drawn a great deal of attention over the past several years, and their applications and development potential are proving to be manifold and vast. The first and only book of its kind, Fluorescent Nanodiamonds is a comprehensive guide to the basic science and technical information needed to fully understand the fundamentals of FNDs and their potential applications across an array of domains. In demonstrating the importance of FNDs in biological applications, the authors bring together all relevant chemistry, physics, materials science and biology. Nanodiamonds are produced by powerful cataclysmic events such as explosions, volcanic eruptions and meteorite impacts. They also can be created in the lab by high-pressure high-temperature treatment of graphite or detonating an explosive in a reactor vessel. A single imperfection can give a nanodiamond a specific, isolated color center which allows it to function as a single, trapped atom. Much smaller than the thickness of a human hair, a nanodiamond can have a huge surface area that allows it to bond with a variety of other materials. Because of their non-toxicity, nanodiamonds may be useful in biomedical applications, such as drug delivery and gene therapy. The most comprehensive reference on a topic of rapidly increasing interest among academic and industrial researchers across an array of fields Includes numerous case studies and practical examples from many areas of research and industrial applications, as well as fascinating and instructive historical perspectives Each chapter addresses, in-depth, a single integral topic including the fundamental properties, synthesis, mechanisms and functionalisation of FNDs The first book published by the key patent holder with his research group in the field of FNDs Fluorescent Nanodiamonds is an important working resource for a broad range of scientists and engineers in industry and academia. It will also be a welcome reference for instructors in chemistry, physics, materials science, biology and related fields.

This book was released on 2004-06-19 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent and forecasted advances in microbiology, molecular biology, and analytical chemistry have made it timely to reassess the current paradigm of relying predominantly or exclusively on traditional bacterial indicators for all types of waterborne pathogens. Nonetheless, indicator approaches will still be required for the foreseeable future because it is not practical or feasible to monitor for the complete spectrum of microorganisms that may occur in water, and many known pathogens are difficult to detect directly and reliably in water samples. This comprehensive report recommends the development and use of a "tool box" approach by the U.S Environmental Protection Agency and others for assessing microbial water quality in which available indicator organisms (and/or pathogens in some cases) and detection method(s) are matched to the requirements of a particular application. The report further recommends the use of a phased, three-level monitoring framework to support the selection of indicators and indicator approaches.Â

Download or read book Trace Metals and Infectious Diseases written by Jerome O. Nriagu and published by MIT Press. This book was released on 2024-06-11 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experts explore the influence of trace metals on the pathogenesis of infectious diseases. Many parts of the world in which common infectious diseases are endemic also have the highest prevalence of trace metal deficiencies or rising rates of trace metal pollution. Infectious diseases can increase human susceptibility to adverse effects of metal exposure (at suboptimal or toxic levels), and metal excess or deficiency can increase the incidence or severity of infectious diseases. The co-clustering of major infectious diseases with trace metal deficiency or toxicity has created a complex web of interactions with serious but poorly understood health repercussions, yet has been largely overlooked in animal and human studies. This book focuses on the distribution, trafficking, fate, and effects of trace metals in biological systems. Its goal is to enhance our understanding of the relationships between homeostatic mechanisms of trace metals and the pathogenesis of infectious diseases. Drawing on expertise from a range of fields, the book offers a comprehensive review of current knowledge on vertebrate metal-withholding mechanisms and the strategies employed by different microbes to avoid starvation (or poisoning). Chapters summarize current, state-of-the-art techniques for investigating pathogen-metal interactions and highlight open question to guide future research. The book makes clear that improving knowledge in this area will be instrumental to the development of novel therapeutic measures against infectious diseases. Contributors M.
