The Group 13 Metals Aluminium, Gallium, Indium and Thallium Chemical Patterns and Peculiarities

Professor Anthony J. Downs
The scopy of Professor Downs' research takes in the synthesis and chemistry of novel inorganic and organometallic compounds, mostly of the typical elements but also of transition metals. He has authored or edited more than 200 publications, including 27 books and review articles.
