About the book
Ruthenium is an element that is loved by researchers, scientists, and engineers. The element is utilized in many scientific and industrial fields. In the periodic table, the element locates below iron but the properties are quite different. Ruthenium is used on the hard disc to expand memory capacities. It is used in organic syntheses as the catalysts. In particular, Noyori et al. won the Nobel Prize in Chemistry in 2001 for the ruthenium-catalyzed asymmetric syntheses. Ruthenium is actively utilized in photochemistry. Ruthenium tris(bipyridyl) complex absorbs visible light and emits room-temperature phosphorescence. The excited states are long-lived and have strong redox abilities. The properties are utilized as the dye in dye-sensitized solar cells. It is also utilized in photoredox catalyses. Ruthenium complexes are also researched as anti-cancer drugs. Ruthenium is a novel element, but the recycle technology has been developed and the price is not so high.
This book aims to review the research topics for ruthenium and introduce the reason why the researchers love ruthenium to who intend to start researches for ruthenium.
