About this collection

Professor Kenneth Wade, F.R.S. 13th October 1932–16th March 2014

This themed collection of 60 Dalton Transactions articles is dedicated to Ken Wade, who very unexpectedly passed away on 16th March 2014. While this sad loss is the reason for this commemoration, it is an honour for me to Guest Edit this collection.

The collection covers a wide and diverse spectrum of topics spanning inorganic chemistry, something that very clearly demonstrates Ken’s significant and wide-ranging contributions to inorganic chemistry in its broadest context. The rapidity with which all of the invited authors agreed to contribute their work to this themed collection of articles unmistakably reflects the great esteem and friendship with which Ken was held, and provides a fitting tribute to the man himself, his huge role as a teacher and mentor, and his important and extensive contributions to chemistry. Without a doubt, Ken is very sorely missed.
