3D Ruthenium Nanoparticle Covalent Assemblies from Polymantane Ligands for Confined Catalysis
International audience; The synthesis of metal nanoparticle (NP) assemblies stabilized by functional molecules is an important research topic in nanoscience, and the ability to control interparticle distances and positions in NP assemblies is one of the major challenges in designing and understanding functional nanostructures. Here, two series of functionalized adamantanes, bis-adamantanes, and diamantanes, bearing carboxylic acid or amine functional groups, were used as building blocks to produce, via a straightforward method, networks of ruthenium NPs. Both the nature of the ligand and the Ru/ligand ratio affect the interparticle distance in the assemblies. The use of 1,3-adamantanedicarb…
LOCAL STRUCTURE OF THE CuCu (EDTA) (H2O)2, 2H2O AMORPHOUS COMPLEX : A JOINT MAGNETIC, LAXS, AND MOLECULAR MECHANICS INVESTIGATION
The short range order in the amorphous CuCu (EDTA) (H2O)2, 2H2O is studied by Large Angle X-ray Scattering (LAXS) and molecular mechanics. Three conformations of the complex molecule are shown to be energetically equivalent, two of which are simultaneously present in the amorphous material.
