[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 (...)

[in2p3-01347982] Characterization and performances of DOSION, a dosimetry equipment dedicated to radiobiology experiments taking place at GANIL

17 mars 2017

Currently,radiobiology experiments using heavy ions at GANIL GrandAccélérateurNationald’IonsLourds) are conducted under the supervision of the CIMAP (Center for research on Ions, MAterials and Photonics). In this context, a new beam monitoring equipment named DOSION has been developed. It allows (...)

[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 (...)
