Ultrasonics International 91 by Yong Zhou Pdf

Ultrasonics International 91 is a documentation of conference proceedings that discusses the status and future of acoustic microscopy and its application to materials research, especially focusing on its quantitative analyses. Acoustic microscopy, using focused waves, has been receiving increased attention as a technology applicable to materials characterization at the microscopic scale. In acoustic microscopy, the excitation and propagation of leaky surface acoustic waves (LSAWs) in the environment of the coupling liquid at the solid specimens are observed. Three types of the systems have been developed: point-focus-beam (PFB), line-focus-beam (LFB), and directional PFB acoustic microscopes. In this paper, a brief history of the practical developments is first presented, followed by LFB acoustic microscopy for quantitative material characterization and some applications concerned with characterization of elastic anisotropy and inhomogeneity of electronic materials, such as LiNb03 and LiTa03 single crystals, and thin-film characterization. This book gives a comprehensive account of the majority of the oral and poster contributions made during the conference, and makes a valuable addition to a student or researchers’ ultrasonic literature.

Ultrasound in Food Processing by Mar Villamiel,José V. García-Pérez,Antonia Montilla,Juan A. Carcel,Jose Benedito Pdf

Part I: Fundamentals of ultrasound This part will cover the main basic principles of ultrasound generation and propagation and those phenomena related to low and high intensity ultrasound applications. The mechanisms involved in food analysis and process monitoring and in food process intensification will be shown. Part II: Low intensity ultrasound applications Low intensity ultrasound applications have been used for non-destructive food analysis as well as for process monitoring. Ultrasonic techniques, based on velocity, attenuation or frequency spectrum analysis, may be considered as rapid, simple, portable and suitable for on-line measurements. Although industrial applications of low-intensity ultrasound, such as meat carcass evaluation, have been used in the food industry for decades, this section will cover the most novel applications, which could be considered as highly relevant for future application in the food industry. Chapters addressing this issue will be divided into three subsections: (1) food control, (2) process monitoring, (3) new trends. Part III: High intensity ultrasound applications High intensity ultrasound application constitutes a way to intensify many food processes. However, the efficient generation and application of ultrasound is essential to achieving a successful effect. This part of the book will begin with a chapter dealing with the importance of the design of efficient ultrasonic application systems. The medium is essential to achieve efficient transmission, and for that reason the particular challenges of applying ultrasound in different media will be addressed. The next part of this section constitutes an up-to-date vision of the use of high intensity ultrasound in food processes. The chapters will be divided into four sections, according to the medium in which the ultrasound vibration is transmitted from the transducers to the product being treated. Thus, solid, liquid, supercritical and gas media have been used for ultrasound propagation. Previous books addressing ultrasonic applications in food processing have been based on the process itself, so chapters have been divided in mass and heat transport, microbial inactivation, etc. This new book will propose a revolutionary overview of ultrasonic applications based on (in the authors’ opinion) the most relevant factor affecting the efficiency of ultrasound applications: the medium in which ultrasound is propagated. Depending on the medium, ultrasonic phenomena can be completely different, but it also affects the complexity of the ultrasonic generation, propagation and application. In addition, the effect of high intensity ultrasound on major components of food, such as proteins, carbohydrates and lipids will be also covered, since this type of information has not been deeply studied in previous books. Other aspects related to the challenges of food industry to incorporate ultrasound devices will be also considered. This point is also very important since, in the last few years, researchers have made huge efforts to integrate fully automated and efficient ultrasound systems to the food production lines but, in some cases, it was not satisfactory. In this sense, it is necessary to identify and review the main related problems to efficiently produce and transmit ultrasound, scale-up, reduce cost, save energy and guarantee the production of safe, healthy and high added value foods.

The Role of Green Chemistry in Biomass Processing and Conversion by Haibo Xie,Nicholas Gathergood Pdf

Sets the stage for the development of sustainable, environmentally friendly fuels, chemicals, and materials Taking millions of years to form, fossil fuels are nonrenewable resources; it is estimated that they will be depleted by the end of this century. Moreover, the production and use of fossil fuels have resulted in considerable environmental harm. The generation of environmentally friendly energy from renewable sources such as biomass is therefore essential. This book focuses on the integration of green chemistry concepts into biomass processes and conversion in order to take full advantage of the potential of biomass to replace nonsustainable resources and meet global needs for fuel as well as other chemicals and materials. The Role of Green Chemistry in Biomass Processing and Conversion features contributions from leading experts from Asia, Europe, and North America. Focusing on lignocellulosic biomass, the most abundant biomass resource, the book begins with a general introduction to biomass and biorefineries and then provides an update on the latest advances in green chemistry that support biomass processing and conversion. Next, the authors describe current and emerging biomass processing and conversion techniques that use green chemistry technologies, including: Green solvents such as ionic liquids, supercritical CO2, and water Sustainable energy sources such as microwave irradiation and sonification Green catalytic technologies Advanced membrane separation technologies The last chapter of the book explores the ecotoxicological and environmental effects of converting and using fuels, chemicals, and materials from biomass. Recommended for professionals and students in chemical engineering, green chemistry, and energy and fuels, The Role of Green Chemistry in Biomass Processing and Conversion sets a strong foundation for the development of a competitive and sustainable bioeconomy. This monograph includes a Foreword by James Clark (University of York, UK).

Output Measurements for Medical Ultrasound by Roy C. Preston Pdf

Medical applications of ultrasound range from therapy, foetal monitoring, diagnostic imaging and blood flow measurement, to surgery and lithotripsy. Ever since the earliest developments of medical ultrasound there has been an interest in the measurement and characterisation of the ultrasonic fields generated in these applications, either for assessment of performance of equipment or for safety. Until recently, procedures for acoustic output measurements were ill-defined, but standards are now being developed internationally by the International Electrotechnical Commission (1EC) and reliable commercial measuring equipment is becoming more widely available. The aim of this book is to introduce acoustic output measurement techniques and to provide an insight into the measurement methods. The material presented is based on a course originally run during November 1989 at the National Physical Laboratory. In addition to the lectures, the course consisted of a series of practicals to allow participants to gain experience of making measurements. Teddington, UK Roy C.
