The preparation of iron (IH) ethoxide was first reported in 1929 simultaneously by Meerwein [1101] and Thiessen [1577]. The aim of the first of these studies was to obtain anew reagent for reduction of carbonyl compounds, and the aim of the second was to obtain a precursor for the preparation of iron hydroxydes and their colloid solutions. The derivatives of the Fe(OAlk)3 series were obtained then by Bradley et al. in 1958 [228], and their magnetic properties and UV-vis spectra were studied in detail in the 1960s by the group of... 

Indeed, with mono-metallic studies, we have found that solvent polarity and warm-up procedure can drastically affect resultant crystallite sizes,(29) magnetic properties,(29,31) and ability to form stable colloidal solutions.(32,34) However, a bimetallic such as Au-Sn has not been examined in this way before (although other bimetallics have yielded interesting SMAD catalysts).(40,60,61,62,63)...

Size-dependent structure and properties of Earth materials impact the geological processes they participate in. This topic has not been fully explored to date. Chapters in this volume contain descriptions of the inorganic and biological processes by which nanoparticles form, information about the distribution of nanoparticles in the atmosphere, aqueous environments, and soils, discussion of the impact of size on nanoparticle structure, thermodynamics, and reaction kinetics, consideration of the nature of the smallest nanoparticles and molecular clusters, pathways for crystal growth and colloid formation, analysis of the size-dependence of phase stability and magnetic properties, and descriptions of methods for the study of nanoparticles. These questions are explored through both theoretical and experimental approaches.
