[hal-01523022] Composite stratifié hybride carbone/lin : caractérisation des renforts Carbon

17 mai 2017

La caractérisation du renfort est importante pour bien comprendre le comportement d'un matériau composite lors de sa mise en oeuvre. Dans cet article, le travail de caractérisation réalisé sur des renforts tissés de lin et de carbone sera présenté. Des observations à la caméra ont été réalisées sur le (...)

[hal-01517558] Thermo-stimulated evolution of crystalline structure and dopant distribution in Cu-doped Y- stabilized ZrO 2 nanopowders

11 mai 2017

This work deals with the effect of Cu doping on thermal stability of the structural properties of Y-stabilized ZrO2 nanopowders and dopants’ spatial distribution. The powders were synthesized by a co-precipitation technique, calcinated at Tc = 500–1100 °C during 2 h and studied by x-ray (...)

[hal-01507361] Alignment control and atomically-scaled heteroepitaxial interface study of GaN nanowires

13 avril 2017

Well-aligned GaN nanowires are promising candidates for building high-performance optoelectronic nanodevices. In this work, we demonstrate the epitaxial growth of well-aligned GaN nanowires on a [0001]-oriented sapphire substrate in a simple catalyst-assisted chemical vapor deposition process (...)

[hal-01504807] Modélisation biophysique des effets radiosensibilisants des nanoparticules

10 avril 2017

L’enjeu majeur de la radiothérapie est de concentrer la dose d’irradiation dans les cellules cancéreuses tout en épargnant au mieux les cellules saines. Parmi les stratégies envisagées, l’utilisation de radiosensibilisants vise à amplifier les effets destructeurs de dose dans la tumeur. Les (...)

[cea-01493350] In situ and time-resolved infrared detection of the reactivity induced by electrons in polymer films

22 mars 2017

The real time and in situ analysis of chemical reactions such as polymerization reactions, polymer degradation, and oxidation of polymers is of utmost importance. Surprisingly, only few experimental tools allowing this are available. To bridge this gap, we have developed a new experimental (...)

[hal-01467998] Sodalite cages of EMT zeolite confined neutral molecular-like silver clusters

15 février 2017

Stable luminescent silver clusters in nanosized EMT zeolite suspension were prepared and directly observed with high-resolution transmission electron microscopy (HRTEM). The luminescence of the Ag clusters remains stable in time due to their stabilization within the sodalite cages (0.7 nm) of (...)

[in2p3-01464846] Role of a neighbor ion in the fragmentation dynamics of covalent molecules

10 février 2017

Fragmentation of molecular nitrogen dimers (N2)2 induced by collision with low energy 135 keV Ar 9+ ions is studied to evidence the influence of a molecular environment on the fragmentation dynamics of N2 cations. Following the capture of three or four electrons from the dimer, the 3-body N + 2 (...)
