In the context of the study of the interplay between magnetism and superconductivity, a phase transition has been evidenced as a function of magnetic field between two phases having identical magnetic symmetry. Since this effect cannot be magnetically driven, it implies a modification of the nature ... Lire la suite »

The properties of hard X-ray to excite light emission can be combined simultaneously with X-ray fluorescence techniques to study nanoscale devices as demonstrated for multiple quantum well (MQW) InGaN/GaN core/shell wires integrated in blue LED emitters. This study allowed us to understand the ... Lire la suite »

Legend: Q-constant energy scans (solid symbols), at two Bragg positions shown in the inset, fitted by a series of Gaussian functions (solid lines). This figure emphasizes one series of transverse modes when the scattering vector Q is parallel to the direction of the ordered antiferromagnetic ... Lire la suite »

In oleaginous seeds, the energy reserves are mainly triacylglycerols that are liquid lipids contained inside micrometric vesicles, called oil bodies (OB). Seeds are of first importance for human and animal feeds, for biofuels sources and their economic weight is far from being negligible. Therefore ... Lire la suite »

Graphite is widely used as an anode material for lithium ion batteries. Lithium atoms are stored with a well defined periodicity, called "stage" between carbon planes. The standard model describes the staging with pseudo-infinite lithium planes alternating with empty planes. Daumas and ... Lire la suite »

Mesoporous alumina (Al2O3) presents itself as a technologically important material due to its high surface area and catalytic properties. However, the characterization of this material remains elusive to various techniques. Using a hyperpolarization technique called dynamic nuclear polarization ... Lire la suite »
