Runaway electron beam control

Basil Duval, Stefano Coda, Joan Decker, Umar Sheikh, Cristian Galperti, Diego Carnevale, Filippo Bagnato, Georgios Pappas, Gergely Papp

Post-disruption runaway electron (RE) beams in tokamaks with large current can cause deep melting of the vessel and are one of the major concerns for ITER operations. Consequently, a considerable effort is provided by the scientific community in order to t ...

Validation of the ICRF antenna coupling code RAPLICASOL against TOPICA and experiments

Olivier Sauter, Basil Duval, Stefano Coda, Timothy Goodman, Yves Martin, Jean-Marc Moret, Duccio Testa, Patrick Blanchard, Bruno Marchand, Holger Reimerdes

In this paper we validate the finite element code RAPLICASOL, which models radiofrequency wave propagation in edge plasmas near ICRF antennas, against calculations with the TOPICA code. We compare the output of both codes for the ASDEX Upgrade 2-strap ante ...

Columnar self-assembly of N,N ',N ''-trihexylbenzene-1,3,5-tricarboxamides investigated by means of NMR spectroscopy and computational methods in solution and the solid state

Diego Carnevale, Mathieu Baudin

The columnar self-assembly resulting from units of N, N', N"-trihexylbenzene-1,3,5-tricarboxamide is investigated in solution and the solid state by means of NMR spectroscopy. A parallel computational study utilizing both semiempirical and DFT methods allo ...

Exciting Wide NMR Spectra of Static Solid Samples with Weak Radiofrequency Fields

Geoffrey Bodenhausen, Diego Carnevale, Srinivas Chinthalapalli

Trains of short pulses in the manner of `delays alternating with nutations for tailored excitation' (DANTE) have been applied to the Pake patterns of protons of water molecules trapped in a static powdered sample of barium chlorate monohydrate. The spin dy ...

NMR spectroscopy and DFT calculations of a self-assembled arene ruthenium rectangle obtained from a combination of coordination and hydrogen bonds

Diego Carnevale

The hydrogen-bonded arene ruthenium metalla-rectangle, (p-cymene)(2)Ru-2(OOnOO)(UPy)(2)(4+), obtained from 1-(4-oxo-6-undecyl-1,4-dihydropyrimidin-2-yl)-3-(pyridin-4-ylmethyl)urea (UPy) and the dinuclear arene ruthenium clip (p-cymene)(2)Ru-2(OOnOO)Cl ...

Homonuclear decoupling for spectral simplification of carbon-13 enriched molecules in solution-state NMR enhanced by dissolution DNP

Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin, Diego Carnevale, Srinivas Chinthalapalli

Complex overlapping multiplets due to scalar couplings (n)J(C-13, C-13) in fully C-13-enriched molecules can be simplified by polychromatic irradiation of selected spins. The signal intensities of the remaining non-irradiated signals are proportional to th ...

Rotation-induced recovery and bleaching in magnetic resonance

Geoffrey Bodenhausen, Diego Carnevale, Angel Joaquin Perez Linde, Srinivas Chinthalapalli

Thurber and Tycko recently described a 'bleaching effect' that occurs in magnetic resonance when solid samples that are doped with paramagnetic agents are subjected to rotation by magic angle spinning (MAS) in a static magnetic field with a rotation period ...

Challenges in preparing, preserving and detecting para-water in bulk: overcoming proton exchange and other hurdles

Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin, Jonas Milani, Diego Carnevale, Nicola Salvi, Daniele Mammoli, Roberto Buratto, Estel Canet Martinez

Para-water is an analogue of para-hydrogen, where the two proton spins are in a quantum state that is antisymmetric under permutation, also known as singlet state. The populations of the nuclear spin states in para-water are believed to have long lifetimes ...

Insights into the Catalytic Activity of Nitridated Fibrous Silica (KCC-1) Nanocatalysts from N-15 and Si-29 NMR Spectroscopy Enhanced by Dynamic Nuclear Polarization

Geoffrey Bodenhausen, Diego Carnevale, Angel Joaquin Perez Linde

Fibrous nanosilica (KCC-1) oxynitrides are promising solid-base catalysts. Paradoxically, when their nitrogen content increases, their catalytic activity decreases. This counterintuitive observation is explained here for the first time using N-15-solid-sta ...

Probing Al-27-C-13 proximities in metal-organic frameworks using dynamic nuclear polarization enhanced NMR spectroscopy

Geoffrey Bodenhausen, Diego Carnevale

We show how Al-27-C-13 proximities in the microporous metal-organic framework MIL-100(Al) can be probed using advanced Al-27-C-13 NMR methods boosted by Dynamic Nuclear Polarization. ...
