Cyano-bridged mixed valence compounds have been known to exist since 1704, but a lot of interest in the bi-nuclear and tri-nuclear species has emerged only more recently. The growing interest in these complexes is due mainly to their promising and useful applications in electrochromism, molecular magnetism and molecular electronics. These properties are activated by the excitation of their metal-to-metal charge transfer (MMCT) transition. This book characterizes aqueous solutions of the FeHEDTA / [Fe(CN)6]4- system which form intensely colored solutions that absorb strongly in the visible/NIR...

Spatial analysis is the archaeology of space and place and is concerned with the creation of a cultural landscape focusing on archaeoastronomy, geoarchaeology, and ancient landscapes. Incorporating emerging technology such as GPS positioning and new forms of diagnostic imaging, spatial analysis can enable scientists to study the wider landscape of ancient human settlements. The ability to peer through time and clearly view the distribution of settlements and particular landforms and to determine resource areas provides researchers with invaluable information regarding the social relations,...
