Download or read book Ultrafine Bubbles written by Koichi Terasaka and published by CRC Press. This book was released on 2021-09-15 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrafine bubbles (UFBs) are gas-filled bubbles with a diameter smaller than 1 μm. They are sometimes called bulk nanobubbles because these are not on a solid surface but inside a bulk liquid (water). They are already being used in commercial processes such as cleaning and plant cultivation. However, many mysteries still exist with respect to UFBs, such as mechanisms of stability, OH radical formation, and biological and medical effects. This is the first book on UFBs that reviews research done on them. It is helpful for those interested in the fundamentals of this emerging field and its applications, including cleaning, biological, medical, and dental students and researchers.
Download or read book High Intensity Ultrasonic Fields written by L. Rozenberg and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: vi tute of the Academy of Sciences of the USSR. Thus, the book does not contain material on the nonlinear interaction of nonlinear ab sorption of high-intensity acoustic oscillations in solids, etc. Al though the main body of the text generally encompasses the results of the author of the given part of the book, the materials of other Soviet and foreign researchers working in the particular field are also incorporated in the interest of clarity and completeness. Part I presents a survey of the results of investigations con ducted by the author in the nonlinear absorption of,sound in liquids and gases. Of special interest are the effects on nonlinear ab sorption in convergent and divergent cylindrical and spherical fronts. Part n is based on results obtained by the author largely during his tenure at the Acoustics Institute. It is given over to the rather complex and beguiling problem of the radiation pressure, an area that is often imprecisely and at times incorrectly handled. Part lli comprises a survey of our knowledge concerning acoustic streaming. Even though the advances made in this area at the Acoustics Institute are relatively limited, the subject is still important enough to warrant its inclusion as an independent part of the book.
Download or read book Physical Principles of Medical Ultrasonics written by C. R. Hill and published by John Wiley & Sons. This book was released on 2005-08-05 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: The physical properties of ultrasound, particularly its highly directional beam behaviour, and its complex interactions with human tissues, have led to its becoming a vitally important tool in both investigative and interventional medicine, and one that still has much exciting potential. This new edition of a well-received book treats the phenomenon of ultrasound in the context of medical and biological applications, systematically discussing fundamental physical principles and concepts. Rather than focusing on earlier treatments, based largely on the simplifications of geometrical acoustics, this book examines concepts of wave acoustics, introducing them in the very first chapter. Practical implications of these concepts are explored, first the generation and nature of acoustic fields, and then their formal descriptions and measurement. Real tissues attenuate and scatter ultrasound in ways that have interesting relationships to their physical chemistry, and the book includes coverage of these topics. Physical Principles of Medical Ultrasonics also includes critical accounts and discussions of the wide variety of diagnostic and investigative applications of ultrasound that are now becoming available in medicine and biology. The book also encompasses the biophysics of ultrasound, its practical applications to therapeutic and surgical objectives, and its implications in questions of hazards to both patient and operator.

Available in PDF, EPUB and Kindle. Book excerpt: TEAN-LOUIS LUCHE A French poet of this eentury, Pierre Mae Orlan, wrote "Adventure does not exist, it is only in the mind of he who is pursuing it, and, as soon as it is at one's finger tips, it vanishes to come back to life, far away, in a different shape, at the frontiers of imagination". This sentence could be used to define the adventure that many sonochemists experienced. Most of them did not even suspect that the "laboratory trick" they were using was the first contact with a considerable amount of science. If a personal note is allowed here, it ean be interesting to mention the part played by chance in my involvement in sonochemistry. Almost 20 years ago, we had to perform an apparently simple Grignard reaetion with n-butylmagnesium bromide and geranial, but the results were repeatedly unsatisfactory. The one-pot Barbier technique was attempted, also without success. From my studies at the University, I imagined that the failure of the latter reaction could be caused by a common phenomenon known by solid state chemists as passivation, which in some cases can be overcome by ultrasonication. By chance, an ultrasonie bath was sitting on the next beneh, borrowed to clean some equipment. We clamped our reluctant reaction mixture into the bath, the reaction proceeded vigorously, and ... the adventure started. Without knowing anything about cavitation, high energies, ete., we had an illustration of Goethe's word "Am Anfang war die Tat" (at the Beginning was the Act).
Download or read book Ultrasonic Treatment of Light Alloy Melts written by G I Eskin and published by CRC Press. This book was released on 1998-05-06 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first monograph to comprehensively cover the effect of using power ultrasound to refine and solidify aluminium and magnesium alloys. The author is widely regarded as a pioneer in the field, and the text is based on results obtained over the 40 years he has spent developing these techniques. Ultrasonic treatment efficiently removes hydrogen and fine solid inclusions from melts, and also helps create a refined grain structure during solidification in the ultrasonic field. Both the fundamental and applied aspects of the formation of an extremely fine nondentritic grain structure are discussed, as well as the application of ultrasound to the process of zone melting.
Download or read book The Acoustic Bubble written by T Leighton and published by Academic Press. This book was released on 2012-12-02 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Acoustic Bubble describes the interaction of acoustic fields with bubbles in liquid. The book consists of five chapters. Chapter 1 provides a basic introduction to acoustics, including some of the more esoteric phenomena that can be seen when high-frequency high-intensity underwater sound is employed. Chapter 2 discusses the nucleation of cavitation and basic fluid dynamics, while Chapter 3 draws together the acoustics and bubble dynamics to discuss the free oscillation of a bubble and acoustic emissions from such activity. The acoustic probes that are often applied to study the behavior of a bubble when an externally-applied acoustic field drives it into oscillation is deliberated in Chapter 4. The last chapter outlines a variety of effects associated with acoustically-induced bubble activity. The bubble detection, sonoluminescence, sonochemistry, and pulse enhancement are also covered. This publication is a good reference for physics and engineering students and researchers intending to acquire knowledge of the acoustic interactions of acoustic fields with bubbles.

Download or read book The Underwater Handbook written by Charles Shilling and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 929 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook attempts to translate data on various parameters of man's capability in underwater and hyperbaric environments for those without a background in the life sciences. Accomplishing any multifaceted task requires team work, and effective team work depends on facile communication among all participants. To communicate properly, all parties must understand each other's problems and be able to speak a similar language. To this end we believe that this publication will go a long way in furthering the understanding and communication necessary for maximum achievement. The U. S. Navy has a fundamental interest in all types of activities connected with the ocean and is especially interested in the growing field of manned underwater and hyperbaric activities. Thus, the manuscript for this comprehensive book was developed under Office of Naval Research contract N00014-67-A-0214-0013 with The George Washington University. We acknowledge with appreciation the financial support and technical guidance for this undertaking by the Naval Medical Research and Develop ment Command of the Bureau of Medicine and Surgery as well as by the Engineering Psychology Program and the Physiology Program of the Office of Naval Research. JOSEPH P. POLLARD Director Biological and Medical Sciences Division Office of Naval Research vii Preface A need was felt for a book that would document the relationship of the human being to the underwater hyperbaric environment in such a way that the individual unfamiliar with the psychological or biomedical jargon could still understand and appreciate the information.
Download or read book Mechanics and Physics of Bubbles in Liquids written by Leen van Wijngaarden and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: A IUTAM (International Union of Theoretical and Applied Mechanics) Sympo sium 'Mechanics and Physics of Bubbles in Liquids' was held at Pasadena, Calif., USA from 15 through 19 June 1981. The present volume contains the printed version of nearly all papers read at the Symposium. The study of the behaviour of bubbles in liquids was originally stimu lated by problems in cavitation and in boiling ofliquids. Today research is initiated by problems in many other fields as well. In this respect a growing interest from the side of biomechanics may be mentioned. Ordering of the papers could be done either according to the various mechanical and physical aspects of the subject or according to the fields of application. The presentaton at the Symposium contained a bit of both; there was a session on physico-chemical aspects for example and also a session on biological applications. The subdivision in this volume follows roughly the sessions in the Symposium. Most of them start with a paper of a survey nature, reporting progress made in recent years. Here, as in other fields of engineering science, one notes the important part played by experimental techniques and by numerical analysis.
