Superfine Particle Technology

By: Noboru Ichinose,Yoshiharu Ozaki,Seiichiro Kashu

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.

Stereo-Differentiating reactions

The nature of asymmetric reactions

By: Yoshiharu Izumi

Stereo-Differentiating Reactions: The Nature of Asymmetric Reactions provides an introduction to asymmetric reactions. It brings together synthetic organic chemistry, stereochemistry, group theory, the theory of optical rotation, experimental methods, etc., all of which are basic to the study of stereo-differentiating reactions, to form a unified approach based on the new concept of "differentiation." The authors hope that the value of the new concept, which is rather more complex than conventional treatments of asymmetric reactions, will become clear in the present book. This new concept should be useful in many fields of study, not only the development of stereo-differentiating reactions, but also in the study of general reaction mechanisms in organic chemistry. The book contains nine chapters and begins with a historical background of studies on asymmetric reactions. This is followed by separate chapters on molecular symmetry and chirality; nomenclature for chirality, prochirality, and stereo-differentiating reactions; the mechanisms of stereo-differentiating reactions; methods for studying stereo-differentiating reactions; and the basic principle of optical activity.
