Chemically disordered B3–7-nm-diameter FePt nanoparticles are synthesized using the airless operation technique based on decomposition of iron pentacarbonyl and reduction of platinum acetylacetonate. The particle solution is then washed and subsequently deposited onto a thermally oxidized Si substrate. Nanoparticle assemblies are formed after solvent evaporation. The samples are heat-treated us...

Introduction Highly dispersed supported gold catalysts have attracted wide interest because of their high activities and selectivities for reactions including low-temperature oxidation of CO, even in the presence of H2. Notwithstanding extensive research on supported gold catalysts, fundamental questions remain, such as what are the catalytically active sites and reaction mechanisms. By using A...

Catalytic performances of promoted CoMoS catalysts were greatly improved via a synthesis strategy based on the structuration active phase using self-assembled PANI (Polyaniline) nanowires followed by an addition step cobalt acetylacetonate oxidic or sulfided Mo-based hybrids. Taking into account different promotion levels, slabs lengths determined XPS and TEM, highest rate constants normalized ...

various radiometal complexes have been developed for tumor imaging, especially ga-68 tracer. in the present study, the development of a radiogallium bis-thiosemicarbazone complex has been reported. [67ga] acetylacetonate bis(thiosemicarbazone) complex ([67ga] aats) was prepared starting [67ga]gallium acetate and freshly prepared acetylacetonate bis (thiosemicarbazone) (aats) in 30 min at 90°c. ...
