ligand, and in the final chapter, Bunsho Ohtani presents a contri-
bution on photo-catalysis by inorganic solid materials, in which he
revisits the definition, concepts, and experimental procedures.
We appreciate the constructive interaction we had with the
authors of these chapters and thank them for their willingness
to find time to contribute to this thematic issue. We trust that
the readers in the inorganic/bioinorganic chemistry communities
will find this volume informative and useful.
