The SMAD method is a versatile synthetic technique for preparation of organometallic compounds, colloids and nanostructured materials from metals and semiconductors. In this work we use this technique to prepare beta-diketonate complexes of Ba and Cu, nanoparticles of Fe-SiO and copper, and for first time nanoparticles of ionic salt-like compounds.Subjects--Topical Terms:

520 $a The SMAD method is a versatile synthetic technique for preparation of organometallic compounds, colloids and nanostructured materials from metals and semiconductors. In this work we use this technique to prepare beta-diketonate complexes of Ba and Cu, nanoparticles of Fe-SiO and copper, and for first time nanoparticles of ionic salt-like compounds.
520 $a The evaporation and cocondensation of Fe, SiO, and an organic solvent, produces nanoparticles of Fe-SiO that when heat treated and passivated, acquire a core-shell structure that protects the iron core from oxidation, preserving its magnetic properties.
520 $a beta-Diketonate complexes of Ba and Cu have been prepared free of water and with a considerable purity. Moreover, a striking finding was the dependence of the reactivity of the copper particles with their size toward the formation of the beta-diketonate complex.
520 $a Nanocrystalline particles of copper have been prepared, and their chemical and catalytic reactivity have been tested in the Ullman reaction and the hydrogenation of CO2 to form CH3OH. Their chemical reactivity in the Ullman reaction is proportional to their surface area, and more reactive that those found in literature, with a maximum yield of 90% biphenyl at 150°C after 6 h. for the Cu*/toluene sample. Their catalytic activity tested using nanocrystalline ZnO as a support, resulted in a maximum conversion of 80% from CO2 to CH3OH.
520 $a Nanocrystalline LiF particles have been successfully prepared with surface areas of 230--520 m2/g and with crystallite size of 5--10 nm. These particles present resistance to sintering when heated from room temperature up to 200°C. These samples can be densified without crystallite growth.
