Effect of Crystallographic Phase (β vs. γ) and Surface Area on Gas Phase Nitroarene Hydrogenation Over Mo2N and Au/Mo2N

Lioubov Kiwi, Vincent Laporte, Fernando Cardenas Lizana, Daniel André Samuel Lamey

The catalytic action of Mo2N and Au/Mo2N has been assessed in the selective gas phase hydrogenation of p-chloronitrobenzene (p-CNB) to p-chloroaniline (p-CAN). The nitrides were synthesised via temperature programmed treatment of MoO3 in H-2 + N-2 and Au i ...

First search for atmospheric and extraterrestrial neutrino-induced cascades with the IceCube detector

Shirit Cohen, Matthias Wolf, Mathieu Ribordy, Xiaoxia Bai

We report on the first search for atmospheric and for diffuse astrophysical neutrino-induced showers (cascades) in the IceCube detector using 257 days of data collected in the year 2007-2008 with 22 strings active. A total of 14 events with energies above ...

Hyperpolarized Lithium-6 as a Sensor of Nanomolar Contrast Agents

Rolf Gruetter, Cristina Ramona Cudalbu, Arnaud Comment, Sami Jannin, Ruud van Heeswijk, Jacques Van Der Klink, Chiara Perazzolo, Fiodar Kurdzesau

Lithium is widely used in psychotherapy. The Li-6 isotope has a long intrinsic longitudinal relaxation time T-1 on the order of minutes, making it an ideal candidate for hyperpolarization experiments. In the present study we demonstrated that lithium-6 can ...

Lattice anharmonicity in low-dimensional carbon systems

Nicola Marzari, Ramachandra Rao

The anharmonic properties of low-dimensional carbon crystal lattices are reviewed. The energy and crystal momentum conservation rules in two- and one-dimensional crystals lead to a drastic reduction of the phase space available for anharmonic phonon decay. ...

Zr isotope anomalies in chondrites and the presence of Nb-92 in the early solar system

Philippe Gillet

The presence of Zr isotope anomalies in the early solar system is demonstrated with the identification of Zr-92 excesses and Zr-96. deficits in several chondrites and the CAI Allende inclusions. The isotopic composition of Zr in carbonaceous, enstatite, an ...
