Electromagnon dispersion probed by inelastic X-ray scattering in LiCrO2

Henrik Moodysson Rønnow, Christian Rüegg, Sándor Tóth

Inelastic X-ray scattering with meV energy resolution (IXS) is an ideal tool to measure collective excitations in solids and liquids. In non-resonant scattering condition, the cross-section is strongly dominated by lattice vibrations (phonons). However, it ...

Valley polarization by spin injection in a light-emitting van der Waals heterojunction

Andras Kis, Oriol López Sánchez, Dmitry Ovchinnikov, Adrien Victor Allain, Shikhar Misra

The band structure of transition metal dichalcogenides (TMDCs) with valence band edges at different locations in the momentum space could be harnessed to build devices that operate relying on the valley degree of freedom. To realize such valleytronic devic ...

American Chemical Society2016

Understanding the ultrafast evolution of atomic and electronic rearrangements under nonequilibrium conditions in organic, inorganic and biological materials plays a fundamental role in deciphering the mechanism governing chemical and biological functions. ...

Nanoscale Magnetometry with Single Fluorescent Nanodiamonds Manipulated in an Anti-Brownian Electrokinetic Trap

Metin Kayci

Studies on single-molecule spectroscopy and nanoscale detection have been remarkably driven by an interest to reveal quantum and conformational states of single particles, the intra-molecular dynamics and their response to physical observables hidden by en ...

EPFL2016

Sirtuin 3 (Sirt3) is an NAD(+)-dependent mitochondrial deacetylase associated with superoxide dismutase 2 (SOD2)-mediated protection from oxidative stress. We have reported accelerated weight gain and impaired metabolic flexibility in atherosclerotic Sirt3 ...

Measuring changes in substrate utilization in the myocardium in response to fasting using hyperpolarized [1-(13)C]butyrate and [1-(13)C]pyruvate

Arnaud Comment, Josefina Adriana Maria Bastiaansen

Cardiac dysfunction is often associated with a shift in substrate preference for ATP production. Hyperpolarized (HP) (13)C magnetic resonance spectroscopy (MRS) has the unique ability to detect real-time metabolic changes in vivo due to its high sensitivit ...

Probing strongly hybridized nuclear-electronic states in a model quantum ferromagnet

Henrik Moodysson Rønnow, Giovanni Boero, Peter Babkevich, Julian Piatek, Ivan Kovacevic

We present direct local-probe evidence for strongly hybridized nuclear-electronic spin states of an Ising ferromagnet LiHoF4 in a transverse magnetic field. The nuclear-electronic states are addressed via a magnetic resonance in the GHz frequency range usi ...

Novel Instrumentation and Methods for Chemical Applications of Dissolution Dynamic Nuclear Polarization

Jonas Milani

One of the major disadvantages of Nuclear Magnetic Resonance (NMR) is its low sensitivity, mainly due to a very low spin polarization. Since 2003, Dissolution Dynamic Nuclear Polarization (D-DNP) provides a way of overcoming this drawback in solution by in ...

Neutral Aminyl Radicals Derived from Azoimidazolium Dyes

Rosario Scopelliti, Kay Severin, Henrik Moodysson Rønnow, Matthew Wodrich, Andrzej Sienkiewicz, Ivica Zivkovic, Philip Pattison, Euro Solari, Alexander Tskhovrebov, Laurent Alexis Clément Vannay, Léonard Yannick Maurice Eymann, José Luis Bila

The synthesis and characterization of a new class of neutral aminyl radicals is reported. Monoradicals were obtained by reduction of azoimidazolium dyes with potassium. Structural, spectroscopic, and computational data suggest that the spin density is cent ...
