Book Description
Nanofiber Filter Technologies for Filtration of Submicron Aerosols and Nanoaerosols covers the nanoaerosols (less than 100 nanometers) to larger submicron aerosols due mostly to pollution, which are present in high number concentration in our surroundings. People are breathing these nanoaerosols daily without being aware of it. Airborne viruses from flu to coronaviruses are also nanoaerosols. During the COVID-19 pandemic, it took a long time for health authorities and the General Public to recognize the airborne transmission mode of the virus. This leads to inadequate protection and ineffective virus control strategies resulting in high infection and death rates. The book cites evidence and observations pointing to the airborne transmission mode of the coronavirus. It also discusses different filtration technologies using nanofibers to capture these aerosols for short-term filtration, where aerosols are trapped in the filter (depth filtration), and long-term filtration, where aerosols are trapped in the growing filter cake (cake filtration). This book provides a good understanding on how nanofibers, which is of size 1/1000 times that of a normal human hair, can effectively filter these tiny aerosols. NFT, organized in four sections – fundamentals, deep understanding, technologies, and application, covering comprehensively on the subject, is a valuable resource for undergraduates and graduates, engineers, researchers and practitioners in related industries. - Describes technologies with insight and use basic engineering principles to build-up technologies - Includes extensive clear and understandable figures and tables to enhance key concepts - Uses examples throughout to explain engineering principles and interdisciplinary concepts - The only book in the market focusing on nanofiber filter technologies for filtering submicron aerosols and nanoaerosols

Book Description
Filtration of aerosols is omnipresent in our daily lives, in areas as diverse as health, the protection of people and the environment, and air treatment inside buildings. However, the collection of particles within a filter media is not, contrary to popular belief, linked to a simple screen effect. The phenomena involved are much more complex and require the consideration of aerosol interactions, filter media and process conditions to select the best fiber filter for a given application. Aerosol Filtration, book for students, hygiene or process engineers, fibrous media manufacturers, designers, and filtration system suppliers or users addresses the filtration of aerosols in six chapters. These chapters cover physics and aerosol characterization, the fibrous media, and efficiency and filter clogging by solid or liquid aerosols, with special attention to the filtration of the nanoparticles. - Analyses the behavior of fibrous media against solid and liquid aerosols - Presents models of efficiency and pressure drop - Introduces computing elements for estimating the lifetime of filters - Provides guidance for designing filters and predicting their behavior over time

Book Description
Recent toxicological studies show that nanoparticles released in technological processes and combustion processes outside industry can be dangerous for humans especially when entering the body through the mouth and nose. In connection with the above, the use of adequately effective respiratory protection equipment is of great importance in prophylactic and preventive activities. The first part of Nanoaerosols, Air Filtering and Respiratory Protection: Science and Practice refers to the general phenomena of filtration described on the basis of the authors’ own experience and international reports. The book also includes a description of the respiratory system and principles of its functioning and the accumulation of aerosol particles. It goes on to discuss technological innovations regarding the production of filtering materials for protection against nanoparticles and the latest test methods. Finally, the book contains information about the proper selection and use of respiratory protective devices against airborne nanoparticles in the workplace and everyday life. Special attention is paid to proper fit procedures as well as use and maintenance activities of such devices. The content of the book with rich illustrative material has been presented so that it can be used by health and safety experts, students as well as employers, employees and private users of respiratory protective devices. "Through a comprehensive approach to the subject of the work, the authors present theoretical foundations as well as practical solutions that are used in the research and development of personal respiratory protection. The complementarity of the information contained in the book will allow the reader to become familiar with a wide range of knowledge related to the design and manufacture as well as assessment of properties and procedures for the use of respiratory protection against the adverse effects of aerosols, including air contaminated with nanoparticles and microparticles. In my opinion the book is a valuable part of the series Occupational Safety, Health, and Ergonomics: Theory and Practice, published by Taylor & Francis." —Maciej Boguń, ŁUKASIEWICZ – The Textile Research Institute, Łódź

Book Description
AEROSOL SCIENCE TECHNOLOGY AND APPLICATIONS Aerosols influence many areas of our daily life. They are at the core of environmental problems such as global warming, photochemical smog and poor air quality. They can also have diverse effects on human health, where exposure occurs in both outdoor and indoor environments. However, aerosols can have beneficial effects too; the delivery of drugs to the lungs, the delivery of fuels for combustion and the production of nanomaterials all rely on aerosols. Advances in particle measurement technologies have made it possible to take advantage of rapid changes in both particle size and concentration. Likewise, aerosols can now be produced in a controlled fashion. Reviewing many technological applications together with the current scientific status of aerosol modelling and measurements, this book includes: Satellite aerosol remote sensing The effects of aerosols on climate change Air pollution and health Pharmaceutical aerosols and pulmonary drug delivery Bioaerosols and hospital infections Particle emissions from vehicles The safety of emerging nanomaterials Radioactive aerosols: tracers of atmospheric processes With the importance of this topic brought to the public's attention after the eruption of the Icelandic volcano Eyjafjallajökull, this book provides a timely, concise and accessible overview of the many facets of aerosol science.

Book Description
This book documents the proceedings of the Symposium on Particles in Fluids: Detection, Characterization and Control held as a part of the 18th Fine Particle Society meeting in Boston, August 3-7, 1987. This was the Premier symposium on this topic and the response was so good that we have decided to organize it on a biennial basis and the second symposium will be held under the rubric Particles in Gases and Liquids: Detection, Characterization and Control at the 20th Fine Particle Society meeting in Boston, August 22-26, 1989. In the modern manufacture of sophisticated and sensitive microelectronic components and other precision parts, there has been a great deal of concern about yield losses due to micrometer- and submicrometer-sized particles. These particles can originate from a number of sources including fluids, i. e. , gases and liquids used in the manufacturing process. So the detection, characterization and control or removal of these undesirable particles is of cardinal importance and this symposium was conceived and o~ganized with this in mind. The purposes of this symposium were to bring together those actively involved in all aspects of particles in fluids, to provide a forum for discussion of the latest techniques for the detection, characterization and control of particles, and to highlight areas which needed intensified R&D efforts. The printed program contained a total of 46 papers and a variety of topics dealing with various ramifications of particles in fluids were presented.
