Chiral Cyclopentadienyl Ligands Enable a Rhodium(III)-Catalyzed Enantioselective Access to Hydroxychromanes and Phthalides

Nicolai Cramer, Baihua Ye

The demand for efficient chiral cyclopentadienyl ligands (Cp-x) has increased significantly in recent years, partly because Cp*Rh(III) species have been developed as powerful catalysts for directed C-H functionalization reactions. However, a lack of suitab ...

The use of selected neutron absorption resonance filters to suppress spurious events on hot neutron spectrometers

Henrik Moodysson Rønnow, Diane Virginie Marie Lançon

Resonant absorption can be used as a filter for high energy neutron spectroscopy. Here we report the transmission of eight thin foil filters: erbium, indium, iridium, dysprosium, hafnium, gadolinium, cadmium and samarium, measured using neutron time-of-fli ...

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

Davide Ferri

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 ...
