This book advances the use of biodiesel-more environmentally friendly than traditional fossil fuels-by showing how it can be synthesized at a lower cost, with greater efficiency and as a more pure and stable product. It presents methods based on fluorescence spectroscopy, which are less time-consuming than the traditional Rancimat analysis for monitoring stability, and are therefore less prone to allowing oxidative decay in the biofuel. Biodiesel exploits a variety of raw materials, from freshly harvested cottonseed to recycled cooking oil. These are cheap to produce and generate fuel lower in polluting sulphur and aromatic compounds than its petroleum-based equivalent. Beginning by addressing different protocols for synthesis based on fatty acids, methyl and ethyl esters, it then describes chemical analyses essential to establishing the purity of the biodiesel. It highlights in detail the use of multifunctional and synthetic antioxidants, and investigates the impact of synthetic chalcones and their derivatives on the oxidative stability of biodiesel. The author goes on to explain how to ameliorate various influences - UV irradiation and metal contaminants for example - which increase the hazards of oxidation, such as degradation and instability. New pre-treatment procedures performed using ultrasonic energies, thermostatic bath and vortex stirring are not only more environmentally friendly, but cut down on the time-consuming process of determining metal content, and allow for the use of more environmentally friendly aqueous reagents. The book investigates and demonstrates these techniques on the basis of real-world results. Further, it suggests the practical uses of byproducts of biodiesel production, for example, using glycerol as a source of energy and high valuable chemicals. These useful techniques aid any researcher exploring the production process of biodiesel and its stabilization and characteristics.

Incorporating the latest theoretical and experimental developments in the field over the past decade, Brainina and Neyman's Electroanalytical Stripping Methods focuses on the theory associated with the most progressive stripping electroanalytical methods (SEAMs) and their application to environmental monitoring and industry. Wherever appropriate, it highlights the main advantages of these methods, including their extremely low detection limit, the low cost of the instruments used, the possibility of speciation analysis, and their use in the investigation of solids as well as solutions. The combined work of two eminent researchers from the former Soviet Union, the book closes the previous information gap that existed between West and East and now makes accessible the most recent developments from Russia, including a different approach to initial electro-crystallization stages, the interconnection between voltammograms of binary metal systems and work functions, and the use of these phenomena in applied stripping voltammetry. Electroanalytical Stripping Methods also provides a critical assessment of current achievements in the field of electrode materials, and in the design of electrodes and electrochemical cells used in stripping methods. Here, the authors provide unique insight into the advantages of graphite electrodes - largely used in the East - over glassy carbon electrodes generally favored by the West. The book presents a number of other modern ideas, including the theory behind and the application of a new internal standard in stripping voltammetry...the catalysis of metals electrodeposition on the foreign substrate with adatoms...and the electrochemical transformation of solidsand adsorbates and their use in phase analysis and the investigation of the defect structure of solids. Electroanalytical Stripping Methods will prove to be an invaluable tool for professionals involved in environmental monitoring, helping them to develop and use trace analysis in evaluating drinking water, food, waste, and other solids and solutions and to apply stripping voltammetry to the analyses of chemicals. Researchers in the food, clinical, and pharmaceutical industries will similarly use the book to develop and apply SEAMs for trace analysis. Practitioners in the microelectronics industry will find useful information on solids that will help them improve the quality of catalyzers, films, special ceramics, and semiconductors. Finally, medical technicians will tap this resource for the insight it can provide in the electroanalysis of blood, urine, and other body fluids.

Here is an extremely useful overview of photochemical vapor deposition, both its characteristics and potential. The book focuses on the properties of films that have been created by this versatile method and the conditions under which they are grown. The author works from the position that while photochemical vapor deposition (photo-CVD) is not the solution to all low-temperature deposition methodologies, it does provide an added dimension of flexibility to and control over the growth process and has proven to be valuable for those materials and growth steps in device fabrication that are sensitive to the processing temperature. Whenever applicable, the properties of electronic devices incorporating photo-CVD films are presented and numerous tables detail the deposition parameters as well as electrical and structural properties of the films of specific materials. 1992 (0-471-55083-3) 208 pp.

Research and development of solid state gas sensor devices began in the 1950s with several uncoordinated independent efforts. The number and pace of these investigations later accelerated in response to increasing pressure placed on the environment and public health by industrial activities. Since 1970, several thousand articles have been written on the subject, and laboratories around the globe have introduced novel methodologies and devices to address needs associated with particular technological developments. Despite the rapid development of this important new technology, very little has been done to review and coordinate data related to sensor science and technology itself.

Physics, Chemistry and Technology of Solid State Gas Sensor Devices focuses on the underlying principles of solid state sensor operation and reveals the rich fabric of interdisciplinary science that governs modern sensing devices. Beginning with some historical and scientific background, the text proceeds to a study of the interactions of gases with surfaces. Subsequent chapters present detailed information on the fabrication, performance, and application of a variety of sensors.

Types of sensor devices discussed include:

• Gas-sensitive solid state semiconductor sensors
• Photonic and photoacoustic gas sensors
• Fiber optic sensors
• Piezoelectric quartz crystal microbalance sensors
• Surface acoustic wave sensors
• Pyroelectric and thermal sensors

Recent research in science establishes a direct relation between human gut and skin. Several species of live microbes inhabit the human skin and intestines which far outnumbers the mammalian cells in the human body. Research interest of Nextgen scientists is focused on beneficially harnessing this microbial population to address skin disorders like acne, rosacea, eczema, premature aging, and skin cancer which are established to be a result of skin-microbiome dysbiosis. This volume highlights evidence-based endeavours of the scientific community in this sector. Currently there is no concrete literature which gives a detailed vision on the relationship between gut microbiota and skin related disorders. This volume is an attempt to put together available data in the area and demonstrate usefulness of probiotics as a new therapeutic option for management of these skin diseases which currently show poor prognosis, high cost of treatment and compromised quality of life of the patient.

This book focuses on nanomaterials with antibacterial properties. Antibacterial resistance is a growing concern that poses a serious threat to public health worldwide. This book looks at the fabrication, material's properties, and characterization of a range of metallic, bimetallic, and metal-oxide-based nanomaterials that can be exploited for their antimicrobial properties. A key focus of this book is its emphasis on 'green' synthesis of nanomaterials, as many conventional routes of nanomaterial fabrication do not fulfill key sustainability criteria in terms of their toxicity and lack of eco-friendliness. Additionally, this book introduces the application of nanoparticles to veterinary medicine. Given the ever-increasing global livestock population coupled with the emergence of drug-resistant pathogens of animal origin (bacterial, parasitic, and hemoprotozoa), the use of nanoparticles as antibacterial agents represents a paradigm shift in every aspect of veterinary care. Authored by scholars with combined expertise in nanomaterials and veterinary medicine, this book provides valuable information for researchers working on sustainable nanomaterials with antibacterial properties.
