This book reviews the optical spectra of phthalocyanines and related compounds. The book also provides a theoretical background to distinguish their spectra from those of porphyrins as graphically as possible and without mathematicization. Phthalocyanines are tricky because their spectra behave like the sea-god Proteus: depending on conditions they sometimes can be very misleading. Therefore, those who have worked with these compounds for the first time, even educated professional researchers and engineers, may have been embarrassed by the deceptive behavior of phthalocyanines and could have,...

In this book, improvements in the heat resistance of silicon nitride (Si3N4) ceramics using grain boundary control and in plasticity at high temperatures using grain size control in order to reduce the cost of shaping Si3N4 are described.
The heat resistance of Si3N4 is improved by mixing a slight amount of sintering additive as an impurity into the original material powder. The author presents his findings on the high heat resistance of Si3N4.
The author also develops a new...

Oxide materials are good candidates to replace Si devices which are facing performance limits since these materials display unique properties, either due to their composition design and/or doping technique.
The author introduces a means of selecting oxide materials according to their functions and explains metal/oxide interface physics. Material development is the key to matching oxide materials to specific practical applications.
In this book, the investigation and intentional control of metal/oxide interface structure and electrical properties with the data obtained using...

This book introduces the principles and techniques of crystal growth by the flux method, which is arguably the most useful way to obtain millimeter- to centimeter-sized single crystals for physical research.

This monograph shares a newly emerging point of view among researchers and students in the field of materials science. Inspired by the presence of precisely determined molecular-level sequence structures in a wide range of biomolecules, a growing number of synthetic compounds with the same structural feature are appearing day by day. These examples in the interdisciplinary areas of materials science are collected in this monograph to provide readers with a good understanding of the state-of-the-art accessible structural level, characteristic features, and future potentials of these types of...
