Electron trapping in substoichiometric germanium oxide

Alfredo Pasquarello, Peter Broqvist, Jan Felix Binder

Model structures of substoichiometric germanium oxide generated by ab initio molecular dynamics reveal a rich variety of bonding configurations, including threefold coordinated Ge and O atoms which correspond to valence alternation pairs. A sizable fractio ...

U(VI) reduction by spores of Clostridium acetobutylicum

Rizlan Bernier-Latmani, Elena Suvorova Buffat, Harish Veeramani, Elena Cristina Dalla Vecchia, Nicholas Wigginton

Vegetative cells of Clostridium acetobutylicum are known to reduce hexavalent uranium (U(VI)). We investigated the ability of spores of this organism to drive the same reaction. We found that spores were able to remove U(VI) from solution when H, was provi ...

Novel Ruthenium Complexes with Sterically Demanding Cyclopentadienyl Ligands

Barnali Dutta

Investigations of ruthenium halfsandwich complexes have mostly focused on Cp and Cp* based derivatives due to the availability of easily accessible starting materials. However, it is interesting to have complexes with substituted cyclopentadienyl ligands i ...

Reactions of Alkynes with [RuCl(cyclopentadienyl)] Complexes: The Important First Steps

Rosario Scopelliti, Ursula Röthlisberger, Kay Severin, Euro Solari, Basile Curchod, Pablo Campomanes Ramos, Barnali Dutta

Cyclopentadienyl-ruthenium half-sandwich complexes with 2-bound alkyne ligands have been suggested as catalytic intermediates in the early stages of Ru-catalyzed reactions with alkynes. We show that electronically unsaturated complexes of the formula [RuCl ...
