Flame-Made WO3/CeOx-TiO2 Catalysts for Selective Catalytic Reduction of NOx by NH3

Materials based on a combination of cerium-tungsten-titanium are potentially durable catalysts for selective catalytic NOx reduction using NH3 (NH3-SCR). Flame-spray synthesis is used here to produce WO3/CeOx-TiO2 nanoparticles, which are characterized wit ...

Atomic Description of the Interface between Silica and Alumina in Aluminosilicates through Dynamic Nuclear Polarization Surface-Enhanced NMR Spectroscopy and First-Principles Calculations

David Lyndon Emsley, Aaron James Rossini

Despite the widespread use of amorphous aluminosilicates (ASA) in various industrial catalysts, the nature of the interface between silica and alumina and the atomic structure of the catalytically active sites are still subject to debate. Here, by the use ...

Surface charging behavior of nanoparticles by considering site distribution and density, dielectric constant and pH changes – a Monte Carlo approach

Marianne Seijo, Serge Stoll, Fabrice Carnal

Monte Carlo simulations are used to describe the charging behavior of metal oxide nanoparticles thus enabling a novel and original approach to predict nanoparticle reactivity and the possible interactions with biological and environmental molecules. The ch ...

CS2 activation at uranium(III) siloxide ate complexes: the effect of a Lewis acidic site

Marinella Mazzanti, Julie Renée Michelle Andrez

Multimetallic cooperative binding of heteroallenes provides an attractive route to their activation, but the reduction of CS2 at heterobimetallic sites, associating an electron-rich metal with a main group Lewis acid has not been explored. Here we show tha ...

Syntheses, structures and properties of cobalt and manganese complexes based on pyridine-2,3,5,6-tetracarboxylic acid

Weijin Wang, Chi Wai Cheung, Hong-Ling Gao

Two new complexes based on pyridine-2,3,5,6-tetracarboxylic acid(H(4)pdtc) as ligand, {[Co-2(pdtc)(H2O)(4)]center dot H2O}(n) (1) and {Mn-2(pdtc)(H2O)(4)}(n) (2), have been obtained by hydrothermal syntheses and characterized by IR, elemental analysis, X-r ...

Structural insights on cholesterol endosynthesis: Binding of squalene and 2,3-oxidosqualene to supernatant protein factor

Maria Josefina Marcaida Lopez, Michele Cascella, Christos Lamprakis

We present the crystal structures of the SEC14-like domain of supernatant protein factor (SPF) in complex with squalene and 2,3-oxidosqualene. The structures were resolved at 1.75 angstrom (complex with squalene) and 1.6 angstrom resolution (complex with 2 ...

Large, heterometallic coordination cages based on ditopic metallo-ligands with 3-pyridyl donor groups

Rosario Scopelliti, Kay Severin, Philip Pattison, Euro Solari, Matthew David Wise

Ditopic N-donor ligands with terminal 4-pyridyl groups are omnipresent in coordination-based self-assembly. The utilization of ligands with 3-pyridyl donor groups is significantly less common, because the intrinsic conformational flexibility of these ligan ...

Electrochemical oxygen reduction at soft interfaces catalyzed by the transfer of hydrated lithium cations

Hubert Girault, Pekka Eero Peljo, Thomas James Stockmann, Haiqiang Deng

The oxygen reduction reaction by decamethylferrocene (DMFc), triggered by hydrophilic metallic cations behaving as Lewis acids towards water molecules in a homogeneous organic phase reaction, was investigated using cyclic voltammetry at the water|1,2-dichl ...
