Book Description
If a substance is repeatedly subdivided, the result is what are known as "microscopic particles". These particles are distinguished from the solid mass which they originally formed by the size of the surface area per unit weight. This simple difference holds true down to a certain lower size limit, and when this limit is exceeded, a new state of matter is reached, in which the behavior of the particles is quite different to that of the original solid. Particles in this state are termed "superfine particles", and are distinct from ordinary particles. The size of the superfine particles, that is to say the size limit below which particle behavior is completely different from the behavior of the original solid, varies a good deal depending on the physical properties of the substance in question. Properties such as magnetism and electrical resistance are closely related to the internal structural properties of the particles themselves, such as the magnetization processes of their respective magnetic domains, and the mean free path of charged bodies. This internal structure therefore limits the size of the superfine particles. In ceramic processing, on the other hand, the surface area of the particles themselves becomes an even more important factor than their internal structure. In this case, the size of the superfine particles is determined by the interaction between water and solvents on the surface of the particles.

Book Description
Functionalization of material systems is one of the key developments nowadays in the textile industry, where particles are frequently used to enhance the properties of fibers and to add new functionalities. This book focuses on innovative textile materials and is a perfect guide for professionals in the textile industry and scientists alike. An overview of particle technology is provided before addressing all topics relevant to particle-enhanced textiles, i.e. the properties and application of micro/nanoparticles in textiles, production techniques, safety, as well as regulatory and intellectual property aspects. The book covers the composition and applications of various types of textile fillers, finishings, and microfibers. gives an outlook on future trends and challenges in the research, development, and production of nano- and micro-enabled textiles. The authors of the book, who are leading experts in their fields, address many aspects relevant to the use of particle-enhanced textiles in industrial applications as well as in our daily life. A particular emphasis is put on practical examples of applications and products, safety and sustainability issues and the potential for further innovation. This book should bring inspiration for textile scientists in using particles for improving textiles and further expanding their possibilities of use.

Book Description
Engineered Nanoparticles: Structure, Properties and Mechanisms of Toxicity is an indispensable introduction to engineered nanomaterials (ENM) and their potential adverse effects on human health and the environment. Although research in the area of pharmacology and toxicology of ENM is rapidly advancing, a possible correlation between their physicochemical properties and biomedical properties or toxicity is not yet fully understood. This understanding is essential to develop strategies for the safe applications and handling of ENM. The book comprehensively defines the current understanding of ENM toxicity, first describing these materials and their physicochemical properties, and then discussing the toxicological theory and methodology before finally demonstrating the potential impact of ENM on the environment and human health. It represents an essential reference for students and investigators in toxicology, pharmacology, chemistry, material sciences, medicine, and those in related disciplines who require an introduction to ENM and their potential toxicological effects. - Provides state-of-the-art physicochemical descriptions and methodologies for the characterization of engineered nanomaterials (ENM) - Describes the potential toxicological effects of ENM and the nanotoxicological mechanisms of action - Presents how to apply theory to practice in a public health and risk assessment setting

Book Description
Electromagnetic materials have both civilian and defence applications, such as novel antenna designs and protection against high power transients in densely packed printed circuits. For certain applications, the materials may be required to have special frequency response or polarization response to meet the component or system specifications. An in-depth understanding of the responses of materials to electromagnetic waves may even enable us to design and fabricate materials with properties not found in nature.This book constitutes the proceedings of the Symposium on Electromagnetic Materials, which provided a forum for scientists and engineers to report the latest research findings, to exchange ideas and information, and to establish research links.
