Mass Spectrometric and Theoretical Study of Polyiodides: The Connection between Solid State, Solution, and Gas Phases

Paul Joseph Dyson, Zhaofu Fei, Michael Groessl

Polyiodides have been transferred intact from acetonitrile solution to the gas phase and analyzed by mass spectrometry. A range of ions were observed, including I-11, I-13, and I-15, which have higher iodine/iodide ratios than any previously ...

Probing the Transition from Hydrophilic to Hydrophobic Solvation with Atomic Scale Resolution

Majed Chergui, Ivano Tavernelli, Paul Beaud, Thomas James Penfold, Van Thai Pham, Amal El Nahhas, Renske Marjan van der Veen, Frederico Alves Lima

Picosecond and femtosecond X-ray absorption spectroscopy is used to probe the changes of the solvent shell structure upon electron abstraction of aqueous iodide using an ultrashort laser pulse. The transient L-1,L-3 edge EXAFS at 50 ps time delay points to ...

Specific DNA structural attributes modulate platinum anticancer drug site selection and cross-link generation

Paul Joseph Dyson, Alexey Nazarov

Heavy metal compounds have toxic and medicinal potential through capacity to form strong specific bonds with macromolecules, and the interaction of platinum drugs at the major groove nitrogen atom of guanine bases primarily underlies their therapeutic acti ...

Exciton Condensation Driving the Periodic Lattice Distortion of 1T-TiSe_{2}

Corsin Battaglia, Philipp Aebi

We address the lattice deformation of 1T-TiSe2 within the exciton condensate phase. We show that, at low temperature, condensed excitons influence the lattice through electron-phonon interaction. It is found that at zero temperature, in the exciton condens ...

Ultrafast Optical and X-ray Absorption Studies of Solvation Dynamics

Van Thai Pham

Solvation dynamics, the process of solvent reorganization upon electronic excitation of a solute, is central to our understanding chemical reactions in liquid phase. Ultrafast optical studies of solvation dynamics have so far been carried out on polyatomic ...

Direct and mediated electrochemical oxidation of ammonia on boron-doped diamond electrode

Christos Comninellis, Agnieszka Kapalka

Direct (non-mediated) electrochemical oxidation of ammonia on boron-doped diamond (BDD) electrode proceeds mainly at high pH (>8) via free ammonia (NH3) oxidation. To enhance ammonia oxidation on BDD at low pH (

Why are (NN2)Ni pincer complexes active for alkyl-alkyl coupling: ß-H elimination is kinetically accessible but thermodynamically uphill

Rosario Scopelliti, Xile Hu, Oleg Vechorkin, Jan Breitenfeld

Isomerization and olefin exchange experiments show that β-H elimination is kinetically viable but thermodynamically unfavorable in [(MeNN2)Ni-alkyl] complexes. The intermediacy of Ni-hydride species was corroborated by a trapping experiment. The alkyl comp ...

The solvent shell structure of aqueous iodide: X-ray absorption spectroscopy and classical, hybrid QM/MM and full quantum molecular dynamics simulations

Majed Chergui, Ivano Tavernelli, Van Thai Pham, Renske Marjan van der Veen

The L-3 X-ray absorption spectrum of aqueous iodide is reported, and its EXAFS is compared to theoretical spectra reconstructed from the radial distribution function of the iodide hydration obtained from classical, hybrid Quantum Mechanics Molecular Mechan ...

Formation of Iodinated Organic Compounds by Oxidation of Iodide-Containing Waters with Manganese Dioxide

Urs von Gunten

This study shows that iodinated organic compounds can be produced when iodide-containing waters are in contact with manganese oxide bimessite (delta-MnO2) in the pH range of 5-7. In the absence of natural organic matter (NOM), iodide is oxidized to iodate ...
