Small Molecule Activation by Multimetallic Uranium Complexes

Marta Falcone

The development of new processes for the selective and sustainable transformation of abundant small molecules constitutes one of the major research areas in inorganic and organometallic chemistry. These molecules as CO2, CO, N2 and H2 are abundant reservoi ...

Four-electron Reduction and Functionalization of N₂ by a Uranium(III) Bridging Nitride

Marinella Mazzanti, Marta Falcone

N2 is a cheap and widely available but very unreactive molecule. Notably, the only industrial process for the conversion of dinitrogen is the Haber-Bosch process to form ammonia, but under very harsh conditions (high temperature and pressure). Here, we rev ...

Direct Imaging of Dopant Distribution in Polycrystalline ZnO Films

Christophe Ballif, Cécile Hébert, Aïcha Hessler-Wyser, Duncan Thomas Lindsay Alexander, Stéphane Laurent Escrig, Sylvain Nicolay, Monica Morales Masis, Martin Ledinsky, Arthur Brian Aebersold

Two fundamental requirements of transparent conductive oxides are high conductivity and low optical absorptance, properties strongly dependent on the free-carrier concentration of the film. The free carrier concentration is usually-tuned by the addition of ...

Real Space Imaging of Spin Polarons in Zn-Doped SrCu2(BO3)(2)

Frédéric Mila

We report on the real space profile of spin polarons in the quasi-two-dimensional frustrated dimer spin system SrCu2(BO3)(2) doped with 0.16% of Zn. The B-11 nuclear magnetic resonance spectrum exhibits 15 additional boron sites near nonmagnetic Zn impurit ...

Coupled Biogeochemical processes governing the stability of bacteriogenic UO2+x

Elena Suvorova Buffat, Harish Veeramani, Jonathan Sharp

The chemical stability of bacteriogenic “UO2” is one of the seminal issues governing its success as an in-situ waste form in remediated subsurface locations. Little detail is known about the structure and reactivity of this material, but based on compariso ...
