Scandium is a chemical element with symbol Sc and atomic number 21. A silvery-white metallic transition metal, it has historically been sometimes classified as a rare earth element. This book presents topical research material in the study of scandium, including the application of Chiral scandium complexes in asymmetric catalysis; application of scandium oxide in dispenser thermionic cathodes; comparison of mechanisms of scandium recovery by phosphorous-containing inorganic and organic adsorbents; clinical use of scandium enriched power laser in sleep surgery; the physiology of scandium in relation to strain improvement and novel antibiotic discovery; and scandium aluminum nitride nanowires.
